Impact of individual-, environmental-, and policy-level factors on health care utilization among US farmworkers

Objectives. We examined individual-, environmental-, and policy-level correlates of US farmworker health care utilization, guided by the behavioral model for vulnerable populations and the ecological model.Methods. The 2006 and 2007 administrations of the National Agricultural Workers Survey (n = 2884) provided the primary data. Geographic information systems, the 2005 Uniform Data System, and rurality and border proximity indices provided environmental variables. To identify factors associated with health care use, we performed logistic regression using weighted hierarchical linear modeling.Results. Approximately half (55.3%) of farmworkers utilized US health care in the previous 2 years. Several factors were independently associated with use at the individual level (gender, immigration and migrant status, English proficiency, transportation access, health status, and non-US health care utilization), the environmental level (proximity to US–Mexico border), and the policy level (insurance status and workplace payment structure). County Federally Qualified Health Center resources were not independently associated.Conclusions. We identified farmworkers at greatest risk for poor access. We made recommendations for change to farmworker health care access at all 3 levels of influence, emphasizing Federally Qualified Health Center service delivery.US farmworkers face significant disease burden¹ and excessive mortality rates for some diseases (e.g., certain cancers and tuberculosis) and injuries.² Disparities in health outcomes likely stem from occupational exposures and socioeconomic and political vulnerabilities. US farmworkers are typically Hispanic with limited education, income, and English proficiency.³ Approximately half are unauthorized to work in the United States.³ Despite marked disease burden, health care utilization appears to be low.^1,4–9 For example, only approximately half of California farmworkers received medical care in the previous year.⁶ This rate parallels that of health care utilization for US Hispanics, of whom approximately half made an ambulatory care visit in the previous year, compared with 75.7% of non-Hispanic Whites.¹⁰ Disparities in dental care have a comparable pattern.^6,8,11,12 However, utilization of preventive health services is lower for farmworkers^5,7,13,14 than it is for both US Hispanics and non-Hispanic Whites.^15,16Farmworkers face numerous barriers to health care^1,4,17: lack of insurance and knowledge of how to use or obtain it,^6,18 cost,^{5,6,12,13,18–20} lack of transportation,^{6,12,13,19–21} not knowing how to access care,^6,18,20,21 few services in the area or limited hours,^12,20,21 difficulty leaving work,¹⁹ lack of time,^5,13,19 language differences,^6,8,18–20 and fear of the medical system,¹³ losing employment,⁶ and immigration officials.²¹ Few studies have examined correlates of health care use among farmworkers. Those that have are outdated or limited in representativeness.^5,7,14,22,23 Thus, we systematically examined correlates of US health care use in a nationally representative sample of farmworkers, using recently collected data. The sampling strategy and application of postsampling weights enhance generalizability. We selected correlates on the basis of previous literature and the behavioral model for vulnerable populations.²⁴ The behavioral model posits that predisposing, enabling, and need characteristics influence health care use.²⁵ The ecological model, which specifies several levels of influence on behavior (e.g., policy, environmental, intrapersonal),²⁶ provided the overall theoretical framework. To our knowledge, we are the first to extensively examine multilevel correlates of farmworker health care use. We sought to identify farmworkers at greatest risk for low health care use and to suggest areas for intervention at all 3 levels of influence so that farmworker service provision can be improved.     

Hombres Sanos: evaluation of a social marketing campaign for heterosexually identified Latino men who have sex with men and women

Objectives. We evaluated the effectiveness of Hombres Sanos [Healthy Men] a social marketing campaign to increase condom use and HIV testing among heterosexually identified Latino men, especially among heterosexually identified Latino men who have sex with men and women (MSMW).Methods. Hombres Sanos was implemented in northern San Diego County, California, from June 2006 through December 2006. Every other month we conducted cross-sectional surveys with independent samples of heterosexually identified Latino men before (n = 626), during (n = 752), and after (n = 385) the campaign. Respondents were randomly selected from 12 targeted community venues to complete an anonymous, self-administered survey on sexual practices and testing for HIV and other sexually transmitted infections. About 5.6% of respondents (n = 98) were heterosexually identified Latino MSMW.Results. The intervention was associated with reduced rates of recent unprotected sex with both females and males among heterosexually identified Latino MSMW. The campaign was also associated with increases in perception of HIV risk, knowledge of testing locations, and condom carrying among heterosexual Latinos.Conclusions. Social marketing represents a promising approach for abating HIV transmission among heterosexually identified Latinos, particularly for heterosexually identified Latino MSMW. Given the scarcity of evidence-based HIV prevention interventions for these populations, this prevention strategy warrants further investigation.In the United States, adult and adolescent Latino males represent 5.6% of the total population¹ but 18.7% of HIV/AIDS cases.² Low rates of condom use^3–5 and limited HIV testing^5–7 likely contribute to the risk for infection and transmission among Latinos.Sex between men continues to account for the majority of new HIV infections in the United States.² HIV prevention efforts have traditionally targeted gay and bisexual men. However, individuals’ self-identified sexual orientation frequently does not correspond to their sexual behavior,^8–12 and recent research has been focused on men who self-identify as heterosexual but have sex with men. The results of studies on men who have sex with both men and women (MSMW) suggest that, regardless of sexual identity, this population is at greater risk for HIV than are men who exclusively have sex with men; likewise, MSMW are at greater risk than are men who exclusively have sex with women (MSW).^11,13–16 Reasons for greater risk among MSMW may include lower rates of condom use^11,16 and having sexual partners who engage in high-risk sexual practices.¹¹Previous studies have suggested that Latino men are more likely than are White men to engage in bisexual sexual behavior^9,11,17,18 but less likely than are White men to self-identify as gay or bisexual or to disclose their sexual orientation.^19–23 Cultural factors such as homophobia, social stigma related to same-sex practices, and sexual conservatism may inhibit Latino men from self-identifying as homosexual or bisexual.^{10,13,23–26} The degree to which Latinos integrate same-sex sexual practices into their sexual identities may influence their risk for HIV infection.²⁷ Latino MSMW who identify as heterosexual may perceive that they are at lower risk for sexually transmitted infections (STIs) than are gay or bisexual men, and Latino MSMW may thus be less likely to use condoms to protect themselves or their partners. Latino MSMW who identify as heterosexual may also be more likely to resort to substance use to reduce sexual inhibition, thus increasing the likelihood that they will engage in unsafe sex.^19,27Nondisclosure of same-sex sexual practices among MSMW also has significant implications for the health of their female sexual partners.^9,17 More than 70% of Latinas living with HIV/AIDS in the United States were infected via heterosexual contact.² Most cases of heterosexual transmission to Latinas are related to sex with partners who use injection drugs,²⁸ but unprotected sex with men who have multiple partners, including MSMW, has likely contributed to a subset of HIV cases among Latina women.^2,29Social marketing involves applying the principles and techniques of commercial marketing to the promotion of behavioral change for the good of a target audience.^30,31 Social marketing has been successfully used for HIV prevention with gay and bisexual males,^32,33 racial and ethnic minorities,³⁴ and youths.^35–38 Interventions using social marketing have been associated with improvements in HIV/STI testing^32,34 and condom use.^36,37,39,40 To our knowledge, no social marketing campaigns have been designed to reduce HIV risk among heterosexually identified Latino MSMW. Because of the secrecy of their sexual practices and the perceived association of HIV infection with homosexuality,^24,41,42 heterosexually identified Latino MSMW are difficult to reach with HIV prevention efforts. This population is not likely to be exposed to prevention messages or programs targeted to the gay and bisexual communities.¹⁸ Moreover, interventions requiring active recruitment of heterosexually identified MSMW may fail to reach sufficient numbers or may not reach those who are most secretive about their same-sex sexual practices.⁴¹ We sought to evaluate the effectiveness of a social marketing campaign to increase condom use and HIV testing among heterosexual Latino men in northern San Diego County, California, with a special emphasis on heterosexually identified Latino MSMW.     

Health Among Caregivers of Children With Health Problems: Findings From a Canadian Population-Based Study

Objectives. We used population-based data to evaluate whether caring for a child with health problems had implications for caregiver health after we controlled for relevant covariates.Methods. We used data on 9401 children and their caregivers from a population-based Canadian study. We performed analyses to compare 3633 healthy children with 2485 children with health problems. Caregiver health outcomes included chronic conditions, activity limitations, self-reported general health, depressive symptoms, social support, family functioning, and marital satisfaction. Covariates included family (single-parent status, number of children, income adequacy), caregiver (gender, age, education, smoking status, biological relationship to child), and child (age, gender) characteristics.Results. Logistic regression showed that caregivers of children with health problems had more than twice the odds of reporting chronic conditions, activity limitations, and elevated depressive symptoms, and had greater odds of reporting poorer general health than did caregivers of healthy children.Conclusions. Caregivers of children with health problems had substantially greater odds of health problems than did caregivers of healthy children. The findings are consistent with the movement toward family-centered services recognizing the link between caregivers'' health and health of the children for whom they care.Caring for a child with health problems can entail greater than average time demands,^1,2 medical costs,^3,4 employment constraints,^5,6 and childcare challenges.^6–8 These demands may affect the health of caregivers, a notion supported by a variety of small-scale observational studies that have shown increased levels of stress, distress, emotional problems, and depression among caregivers of children with health problems.^1,2,5,9–12Whether these problems are caused by the additional demands of caring for children with health problems or by confounding variables is difficult to answer definitively. The literature reports the identification of a variety of factors purported to be associated with caregiver health, including contextual factors such as socioeconomic status^13–17; child factors such as level of disability,^{1,11,13,18–21} presence of behavior problems,^22–25 and overall child adjustment²⁶; and caregiver-related characteristics such as coping strategies^11,22,27 and support from friends and family.^15,17,28,29 In general, this work has been based on small clinic-based samples^9,30 or specific child populations (e.g., cerebral palsy,^5,25 attention-deficit/hyperactivity disorder^31,32), and typically has been hampered by limited generalizability and a lack of careful, multivariate analysis. Furthermore, most studies have focused on caregivers'' psychological health,^1,2,5,9–12 although physical health effects may also exist among caregivers.^5,19,25,33One of the few studies to involve large-scale, population-based data compared the health of 468 caregivers of children with cerebral palsy to the health of a population-based sample of Canadian parents.⁵ The study showed that caregivers of children with cerebral palsy had poorer health on a variety of physical and psychological health measures. Furthermore, the data were consistent with a stress process model,^5,25 which proposes that additional stresses associated with caring for a child with cerebral palsy directly contribute to poorer caregiver health. However, these findings were based on a specific subpopulation of caregivers and univariate comparisons that could not control for potentially important confounders such as variation in caregiver education, income, and other demographic factors.We used population-based data to test the hypothesis that the health of caregivers of children with health problems would be significantly poorer than that of caregivers of healthy children, even after we controlled for relevant covariates. Our approach of using large-scale, population-based data representing a broad spectrum of childhood health problems³⁴ makes 4 key contributions to the current literature. First, our use of population-based data rather than small-scale, clinic-based studies yielded results that are potentially generalizable to a wide group of caregivers caring for children with health problems. Second, our examination of children with and without health problems allowed us to examine caregiver health effects across a wide variety of caregiving situations. Third, consideration of physical health outcomes (in addition to more regularly studied psychological outcomes) increased our knowledge of the breadth of caregiver health issues. Finally, controlling for relevant covariates allowed us to rule out a number of alternative explanations for caregiver health effects.     

Health status, neighborhood socioeconomic context, and premature mortality in the United States: The National Institutes of Health-AARP Diet and Health Study

Objectives. We examined whether the risk of premature mortality associated with living in socioeconomically deprived neighborhoods varies according to the health status of individuals.Methods. Community-dwelling adults (n = 566 402; age = 50–71 years) in 6 US states and 2 metropolitan areas participated in the ongoing prospective National Institutes of Health–AARP Diet and Health Study, which began in 1995. We used baseline data for 565 679 participants on health behaviors, self-rated health status, and medical history, collected by mailed questionnaires. Participants were linked to 2000 census data for an index of census tract socioeconomic deprivation. The main outcome was all-cause mortality ascertained through 2006.Results. In adjusted survival analyses of persons in good-to-excellent health at baseline, risk of mortality increased with increasing levels of census tract socioeconomic deprivation. Neighborhood socioeconomic mortality disparities among persons in fair-to-poor health were not statistically significant after adjustment for demographic characteristics, educational achievement, lifestyle, and medical conditions.Conclusions. Neighborhood socioeconomic inequalities lead to large disparities in risk of premature mortality among healthy US adults but not among those in poor health.Research dating back to at least the 1920s has shown that the United States has experienced persistent and widening socioeconomic disparities in premature mortality over time.^1–5 However, it has been unclear whether socioeconomic inequalities affect the longevity of persons in good and poor health equally. Socioeconomic status (SES) and health status are interrelated,^6–8 and both are strong independent predictors of mortality.⁹ Low SES is associated with greater risk of ill health and premature death,^{1–5,8,10–13} partly attributable to disproportionately high prevalence of unhealthful lifestyle practices^10,14,15 and physical and mental health conditions.^13,16 Correspondingly, risk of premature mortality is higher in poor than in more affluent areas.^16,17 Although the association between neighborhood poverty and mortality is independent of individual-level SES,^17,18 aggregation of low-SES populations in poor areas may contribute to variations in health outcomes across neighborhoods. Conversely, economic hardships resulting from ill health may lead persons in poor physical or mental health to move to poor neighborhoods.¹⁹ This interrelatedness may create spurious associations between neighborhood poverty and mortality.Although previous studies have found that the risk of premature death associated with poor health status varies according to individuals'' SES,^20,21 no published studies have examined whether the relative risks for premature mortality associated with living in neighborhoods with higher levels of socioeconomic deprivation vary by health status of individuals. Clarifying these relationships will inform social and public health policies and programs that aim to mitigate the health consequences of neighborhood poverty.^22,23We used data from a large prospective study to examine whether the risk of premature mortality associated with neighborhood socioeconomic context differs according to health status at baseline and remains after adjustment for person-level risk factors for mortality, such as SES, lifestyle practices, and chronic medical illnesses.     

The Interaction of Sexual Identity With Sexual Behavior and Its Influence on HIV Risk Among Latino Men: Results of a Community Survey in Northern San Diego County,California

Objectives. We examined the sexual behavior, sexual identities, and HIV risk factors of a community sample of Latino men to inform efforts to reduce Latinos'' HIV risk.Methods. In 2005 and 2006, 680 Latino men in San Diego County, California, in randomly selected, targeted community venues, completed an anonymous, self-administered survey.Results. Most (92.3%) respondents self-identified as heterosexual, with 2.2%, 4.9%, and 0.6% self-identifying as bisexual, gay, or other orientation, respectively. Overall, 4.8% of heterosexually identified men had a lifetime history of anal intercourse with other men. Compared with behaviorally heterosexual men, heterosexually identified men who had sex with both men and women were more likely to have had a sexually transmitted infection, to have unprotected sexual intercourse with female partners, and to report having sex while under the influence of alcohol or other drugs. Bisexually identified men who had sex with men and women did not differ from behaviorally heterosexual men in these risk factors.Conclusions. Latino men who have a heterosexual identity and bisexual practices are at greater risk of HIV infection, and efforts to reduce HIV risk among Latinos should target this group.Latinos and sexual minorities are disproportionately affected by HIV/AIDS. Latinos represented 14% of the US population in 2005,¹ but they accounted for 18% of HIV/AIDS cases diagnosed in 2006.² Although an estimated 6% to 9% of the US population has a lifetime history of homosexual sex,^3,4 men who have sex with men accounted for 49% of all HIV/AIDS cases diagnosed in the United States in 2006.² Sexual risk for HIV varies considerably by sexual orientation, with gay-identified and bisexually identified men generally at greater risk.^5,6 However, a person''s self-identified sexual orientation frequently does not correspond to his or her sexual behavior.^7–9Within Latino culture, it is possible for a man to have sex with men while maintaining a heterosexual identity and protecting his sense of masculinity.^10–13 For Latino men, sexual identity appears to be contingent upon certain behavioral and contextual factors, such as whether they have female sexual partners, are primarily attracted to women, adopt an insertive role in sexual practices, have sex with effeminate men, or have sex with men when under the influence of alcohol or drugs. Homophobia, social stigma attached to same-sex practices, and sexual conservatism are commonly found throughout Latino culture and may inhibit Latino men who have sex with men from self-identifying as gay or bisexual.^9,10,14–16 Research suggests that Latino men are more likely than are White men to engage in bisexual behavior (i.e., to have sex with both men and women)^8,17,18 but are less likely than are White men to disclose a nonheterosexual orientation.^16,19,20Among men, bisexual behavior appears to be more prevalent than bisexual identity. Although approximately 1% to 2% of the US male population identifies as bisexual,^3,4 rates of male bisexual behavior in national samples have ranged from 1% to 5%.^4,21,22 However, these estimates are questionable because of differences in sampling methods and varying definitions of bisexuality.²³ Recent research conducted in the United States suggests that men who have sex with men and women (MSMW) are at greater risk of HIV infection than men who have sex with men (MSM) exclusively and men who have sex with women (MSW) exclusively.^24–26 By contrast, investigators in Mexico have found that MSMW who self-identify as bisexual practice less risky sexual behaviors with their male partners than do exclusively gay men.⁶It has been difficult to quantify the population of heterosexually identified Latino MSMW because of the secretive nature of their sexual practices. In a homophobic cultural context, the fear of social rejection encourages people to hide their same-sex sexual behavior and lead a double life.¹⁰ A study involving a large population of HIV-positive MSM found that 15% of the Latino sample identified as heterosexual had a history of same-sex intercourse,²⁷ whereas a survey of 455 men recruited from gay-oriented publications and venues in 12 US cities found that 17% (n = 26) of Hispanic respondents (as per terminology used in the original survey) reported being “on the down low”.⁹ Although these results may not generalize to community-based US samples of Latino men, they suggest that a substantial proportion of heterosexually identified Latino men have a history of sex with men. Similarly, a household probability survey in Mexico City found that 73% of men with a lifetime history of bisexual practices identified as heterosexual, as did 29% of those with a lifetime history of having sex only with men.⁶Men''s nondisclosure of sexual practices with men has implications for the health of their female sexual partners.^8,17 In the United States in 2006, Latinas accounted for 23.7% of HIV infections among Hispanics; of these, an estimated 51.7% were infected through heterosexual contact.² Although most cases of heterosexual transmission to Latinas are related to sex with injection drug users,²⁸ women who have unprotected sex with heterosexually identified MSMW are also at risk and are likely a subset of this population.Although there is some evidence of greater HIV risk among MSMW than among MSM or MSW,^24–26 previous research has not examined the roles that both sexual behavior and sexual identity play in HIV risk among Latino men in particular. Sexual identity may influence HIV risk among Latino MSMW because a man who identifies as heterosexual may perceive that he is at lower risk of sexually transmitted infections (STIs) than are gay or bisexual men and may thus take fewer measures to protect himself or his partner. MSMW who identify as heterosexual may also be more likely to resort to substance use to reduce sexual inhibition, thus increasing the likelihood that they will engage in unsafe sex.²⁹Our goal was to learn more about the sexual practices of Latino men and to better understand the interactions among sexual behaviors and sexual identities in this population so as to inform efforts to reduce HIV risk among Latinos. Using survey data, we examined the sexual behavior of a community sample of Latino men; determined the proportions of MSM, MSW, and MSMW among them; elicited any discrepancies between their sexual behavior and their sexual identity; and searched for differences in HIV risk by sexual orientation.     

Walking and Cycling to Health: A Comparative Analysis of City, State, and International Data

Objectives. We sought to determine the magnitude, direction, and statistical significance of the relationship between active travel and rates of physical activity, obesity, and diabetes.Methods. We examined aggregate cross-sectional health and travel data for 14 countries, all 50 US states, and 47 of the 50 largest US cities through graphical, correlation, and bivariate regression analysis on the country, state, and city levels.Results. At all 3 geographic levels, we found statistically significant negative relationships between active travel and self-reported obesity. At the state and city levels, we found statistically significant positive relationships between active travel and physical activity and statistically significant negative relationships between active travel and diabetes.Conclusions. Together with many other studies, our analysis provides evidence of the population-level health benefits of active travel. Policies on transport, land-use, and urban development should be designed to encourage walking and cycling for daily travel.Many nations throughout the world have experienced large increases in obesity rates over the past 30 years.^1,2 The World Health Organization estimates that more than 300 million adults are obese,³ putting them at increased risk for diseases such as diabetes, hypertension, cardiovascular disease, gout, gallstones, fatty liver, and some cancers.^4,5 Several studies have linked the increase in obesity rates to physical inactivity^6–8 and to widespread availability of inexpensive, calorie-dense foods and beverages.^1,9The importance of physical activity for public health is well established. A US Surgeon General''s report in 1996, Physical Activity and Health,¹⁰ summarized evidence from cross-sectional studies; prospective, longitudinal studies; and clinical investigations. The report concluded that physical inactivity contributes to increased risk of many chronic diseases and health conditions. Furthermore, the research suggested that even 30 minutes per day of moderate-intensity physical activity, if performed regularly, provides significant health benefits. Subsequent reports have supported these conclusions.^11–13The role of physical activity in prevention of weight gain is well documented.¹⁴ Strong evidence from cross-sectional studies has established an inverse relationship between physical activity and body mass index.^15,16 In addition, longitudinal studies have shown that exercisers gain less weight than do their sedentary counterparts.^6,8 Thus, the obesity epidemic may be explained partly by declining levels of physical activity.^1,17,18A growing body of evidence suggests that differences in the built environment for physical activity (e.g., infrastructure for walking and cycling, availability of public transit, street connectivity, housing density, and mixed land use) influence the likelihood that people will use active transport for their daily travel.^19,20 People who live in areas that are more conducive to walking and cycling are more likely to engage in these forms of active transport.^21–25 Walking and cycling can provide valuable daily physical activity.^26–30 Such activities increase rates of caloric expenditure,³¹ and they generally fall into the moderate-intensity range that provides health benefits.^32–35 Thus, travel behavior could have a major influence on health and longevity.^29,30,36,37Over the past decade, researchers have begun to identify linkages between active travel and public health.^38–40 Cross-sectional studies indicate that walking and cycling for transport are linked to better health. The degree of reliance on walking and cycling for daily travel differs greatly among countries.^39,41 European countries with high rates of walking and cycling have less obesity than do Australia and countries in North America that are highly car dependent.²⁶ In addition, walking and cycling for transport are directly related to improved health in older adults.⁴² The Coronary Artery Risk Development in Young Adults Study found that active commuting was positively associated with aerobic fitness among men and women and inversely associated with body mass index, obesity, triglyceride levels, resting blood pressure, and fasting insulin among men.^26,39,41,43Further evidence of the link between active commuting and health comes from prospective, longitudinal studies.⁴⁴ Matthews et al. examined more than 67 000 Chinese women in the Shanghai women''s health study and followed them for an average of 5.7 years.³⁷ Women who walked (P < .07) and cycled (P < .05) for transport had lower rates of all-cause mortality than did those who did not engage in such behaviors. Similarly, Andersen et al. observed that cycling to work decreased mortality rates by 40% among Danish men and women.³⁶ A recent analysis of a multifaceted cycling demonstration project in Odense, Denmark, reported a 20% increase in cycling levels from 1996 to 2002 and a 5-month increase in life expectancy for males.⁴⁵We analyzed recent evidence from a variety of data sources that supports the crucial relationship between active travel, physical activity, obesity, and diabetes. We used city- and state-level data from the United States and national aggregate data for 14 countries to determine the magnitude, direction, and statistical significance of each relationship.     

National Trends in Smoking Behaviors Among Mexican,Puerto Rican,and Cuban Men and Women in the United States

Objectives. We examined trends in smoking behaviors across 2 periods among Mexicans, Puerto Ricans, and Cubans in the United States.Methods. We analyzed data from the 1992–2007 Tobacco Use Supplements to the Current Population Survey. We constructed 2 data sets (1990s vs 2000s) to compare smoking behaviors between the 2 periods.Results. Significant decreases in ever, current, and heavy smoking were accompanied by increases in light and intermittent smoking across periods for all Latino groups, although current smoking rates among Puerto Rican women did not decline. Adjusted logistic regression models revealed that in the 2000s, younger Mexicans and those interviewed in English were more likely to be light and intermittent smokers. Mexican and Cuban light and intermittent smokers were less likely to be advised by healthcare professionals to quit smoking. Mexicans and Puerto Ricans who were unemployed and Mexicans who worked outdoors were more likely to be heavy smokers.Conclusions. Increases in light and intermittent smoking among Mexican, Puerto Rican, and Cuban Americans suggest that targeted efforts to further reduce smoking among Latinos may benefit by focusing on such smokers.Since 2000, Latinos have experienced the largest population growth of all US racial/ethnic groups, making Latinos the largest ethnic minority group in the country at 16.3% of the population.1 Mexicans, Puerto Ricans, and Cubans are the 3 largest Latino national and family background groups in the United States.1 The leading causes of death among Latinos are coronary heart disease and cancer, both of which are strongly associated with tobacco use.2,3 Although differences in smoking rates by Latino national origin groups have been found,4–6 very little research has examined trends in smoking behaviors for various Latino national origin groups by gender in the United States.The aggregation of smoking rates for various Latino national origin groups masks important variations within the population group.4 For example, smoking prevalence rates as determined by national data from 2008 are highest among Cubans (21.5%), followed by Mexicans (20.1%), and Puerto Ricans (18.6%).3 Puerto Ricans and Cubans are also more likely to be current smokers than are Mexicans.7 Furthermore, although research grounded on a nationally representative sample found that Latinos were approximately 4.5 times more likely to be light smokers than were non-Hispanic Whites,8 that study provided only aggregated rates for all Latinos and did not differentiate between national origin groups. Gender differences have also been reported among disaggregated Latino groups. A higher prevalence of smoking has been reported among Mexican (25.0%), Puerto Rican (27.6%), and Cuban (24.7%) men than among Mexican (10.4%), Puerto Rican (24.2%), and Cuban (12.4%) women.7 The lower rates of smoking among women have been consistent in surveys of Latinos.5,7,9 Results from these studies, although informative, have generally been determined by aggregated Latino data or data from a single survey time point. Although such data are valuable and can demonstrate existing gender differences, national-level trends from Latino nationality groups in the United States add valuable information that have not been previously reported.Previous research has also identified social and environmental factors associated with Latinos’ smoking behaviors. Acculturation to mainstream US culture plays a significant role in one’s health behaviors,10 and as Latinos acculturate, their smoking behaviors become similar to those of non-Hispanic Whites.7 Existing research has also revealed that Latinos are less likely to quit smoking,11 receive tobacco screening, and be advised to quit by a physician than are non-Hispanic Whites.12–15 A health professionals’ advice to quit smoking has been found to increase the likelihood that a smoker will successfully quit.16,17 Lastly, workplace smoking policies have also influenced smoking prevalence and intensity.18–20 Work environments adopting a smoke-free policy saw a 14% decrease in individuals’ smoking.21 When examining national-level smoking behaviors among Latinos, it is important to account for social and environmental factors such as acculturation, physician advice to quit smoking, and work environment smoking policies, as they may influence smoking behaviors.Existing research on smoking behaviors among Latino national origin groups has been predicated on data from specific regions of the United States.4,22–25 Although regional data are important for the development of community-level interventions,4 national-level data provide an overview of the country’s progress in tobacco control as well as remaining and emerging challenges for Latinos nationwide. We compared smoking behaviors across 2 periods, about a decade apart, among Mexicans, Puerto Ricans, and Cubans. Our goals in these analyses were (1) to compare Latino national origin groups across 2 periods to examine factors affecting changes in smoking behavior within and between groups, and (2) to evaluate demographic factors that influence current smoking behaviors within Latino national origin groups in the most recent period available. Examining long-term national trends in Latino smoking behaviors may prove vital to policymakers, public health officials, community workers, and interventionists as they address tobacco-related issues.     

Prevalence,Harm Perceptions,and Reasons for Using Noncombustible Tobacco Products Among Current and Former Smokers

Objectives. We provided estimates of noncombustible tobacco product (electronic nicotine delivery systems [ENDS]; snus; chewing tobacco, dip, or snuff; and dissolvables) use among current and former smokers and examined harm perceptions of noncombustible tobacco products and reasons for their use.Methods. We assessed awareness of, prevalence of, purchase of, harm perceptions of, and reasons for using noncombustible tobacco products among 1487 current and former smokers from 8 US designated market areas. We used adjusted logistic regression to identify correlates of noncombustible tobacco product use.Results. Of the sample, 96% were aware of at least 1 noncombustible tobacco product, but only 33% had used and 21% had purchased one. Noncombustible tobacco product use was associated with being male, non-Hispanic White, younger, and more nicotine dependent. Respondents used noncombustible tobacco products to cut down or quit cigarettes, but only snus was associated with a higher likelihood of making a quit attempt. Users of noncombustible tobacco products, particularly ENDS, were most likely to endorse the product as less harmful than cigarettes.Conclusions. Smokers may use noncombustible tobacco products to cut down or quit smoking. However, noncombustible tobacco product use was not associated with a reduction in cigarettes per day or cessation.The use of noncombustible tobacco products has increased rapidly in recent years1–3 and may continue to rise in response to restrictions such as smoke-free indoor air laws and rising cigarette taxes.4–8 Noncombustible tobacco products can be grouped into 2 broad categories—aerosolized products such as e-cigarettes, or more accurately termed electronic nicotine delivery systems (ENDS), which deliver nicotine primarily through vapor inhalation that mimics smoking a traditional cigarette,9 and smokeless tobacco products such as chew, dip, or snuff; snus; and dissolvables, which deliver nicotine via oral mucosal absorption.10 These products are marketed to appeal to unique target audiences,9,11–13 such as smokers and young adults, and vary in levels of harmful constituents.9Noncombustible tobacco products are a critical part of the tobacco industry’s strategy to navigate the changing tobacco product landscape. Phillip Morris14,15 and RJ Reynolds16 have announced their intent to develop and market noncombustible tobacco products as part of a shift to reduced harm products.17 In some cases, noncombustible tobacco products have been used to expand the appeal of established cigarette brands to a broader spectrum of consumers, as with RJ Reynolds’s Camel Snus product.18 Most ENDS are marketed and sold independently; however, this is changing with Lorillard’s acquisition of blu eCigs in 201219,20 and the recent launches of RJ Reynolds’s Vuse digital vapor cigarettes21,22 and Altria’s MarkTen e-cigarettes.23Noncombustible tobacco product awareness and prevalence vary by product. In 2010, approximately 40% of adults reported awareness of e-cigarettes,24,25 rising to nearly 60% in 201125; awareness approached 75% among current and former smokers in 2010 to 2011.26 Between 1.8% and 3.4% of the adult general population has tried an e-cigarette,24,25,27,28 including up to 21.2% of current smokers.25,26 More than 40% of adults have heard of snus,29 5% have tried the product,29 and 1.4% are current users.30 Awareness of dissolvables is low (10%), and use is even lower (0.5%).29 Noncombustible tobacco product use is highest among young adults26,31 and smokers.24,27,28Although use of noncombustible tobacco products could potentially reduce harm associated with smoking if they replace cigarettes,32,33 some studies suggest that current smokers who use noncombustible tobacco products do not reduce combustible use and may delay cessation.12,34–37 For example, a study by Wetter et al.38 found that dual users of smokeless tobacco products and cigarettes were less likely to quit than were either smokeless tobacco product or cigarette users alone. This is of concern given the rising rates of dual use; a recent study reported that 30% of young adults who smoke cigarettes use at least 1 other tobacco product.31 Dual use is more prevalent among men,39,40 those of lower socioeconomic status,39,41 and youths and young adults.35,41,42Studies show that most users (65%–85%) perceive ENDS as less harmful than cigarettes,24,26,43 and 40% to 50% perceive snus and dissolvables as equally harmful as cigarettes.29 Few studies have examined reasons for use; one study of visitors to ENDS and smoking cessation Web sites found that nearly 85% used ENDS because they believed that they were less toxic than tobacco; other responses included use of ENDS to deal with cravings or withdrawal, to quit smoking, and to save money.43 Focus group research has shown that adults associate snus and dissolvables with historic images of chewing tobacco,34,44 express skepticism that the products are safer than cigarettes,34 do not view them as substitutes for cigarettes,34,44 and express concern about the user’s lack of control of nicotine ingestion relative to cigarettes.44 By contrast, young adults expressed positive perceptions of snus, dissolvables, and ENDS, in part because of a willingness to experiment with new products and because they are available in flavors.45With the ever-changing tobacco marketplace and the tobacco companies’ commitment to the development and promotion of noncombustible tobacco products, surveillance is critical. This study built on previous research to provide current estimates of noncombustible tobacco product use among current and former smokers and examined harm perceptions of noncombustible tobacco products and reasons for their use.     

Suicidal Behavior Among Female Sex Workers in Goa, India: The Silent Epidemic

Objectives. We sought to study suicidal behavior prevalence and its association with social and gender disadvantage, sex work, and health factors among female sex workers in Goa, India.Methods. Using respondent-driven sampling, we recruited 326 sex workers in Goa for an interviewer-administered questionnaire regarding self-harming behaviors, sociodemographics, sex work, gender disadvantage, and health. Participants were tested for sexually transmitted infections. We used multivariate analysis to define suicide attempt determinants.Results. Nineteen percent of sex workers in the sample reported attempted suicide in the past 3 months. Attempts were independently associated with intimate partner violence (adjusted odds ratio [AOR] = 2.70; 95% confidence interval [CI] = 1.38, 5.28), violence from others (AOR = 2.26; 95% CI = 1.15, 4.45), entrapment (AOR = 2.76; 95% CI = 1.11, 6.83), regular customers (AOR = 3.20; 95% CI = 1.61, 6.35), and worsening mental health (AOR = 1.05; 95% CI = 1.01, 1.11). Lower suicide attempt likelihood was associated with Kannad ethnicity, HIV prevention services, and having a child.Conclusions. Suicidal behaviors among sex workers were common and associated with gender disadvantage and poor mental health. India''s widespread HIV-prevention programs for sex workers provide an opportunity for community-based interventions against gender-based violence and for mental health services delivery.Suicide is a public health priority in India. Rates of suicide in India are 5 times higher than in the developed world,^1,2 with particularly high rates of suicide among young women.^3–5 Verbal autopsy surveillance from southern India suggests that suicide accounts for 50% to 75% of all deaths among young women, with average suicide rates of 158 per 100 000.²Common mental disorders such as depressive and anxiety disorders, and social disadvantage such as gender-based violence and poverty, are major risk factors for suicide among women.^1,3,6–8 Although research from high-income countries shows that common mental disorders are a major contributor to the risk of suicidal behavior, their role is less clear in low- and middle-income countries in which social disadvantage has been found to be at least as important.^1,3,6–8 Gender disadvantage is increasingly seen as an important contributing factor to the high rates of suicide seen among women in Asia.^1,3,6,7 Gender-based violence is a common manifestation of gender disadvantage and has been linked with common mental disorders and suicide in population-based studies of women and young adults in Goa, India.^4,5,9 Lack of autonomy, early sexual debut, limited sexual choices, poor reproductive health, and social isolation are other manifestations of gender disadvantage.Sex work in India is common. An estimated 0.6% to 0.7% of the female adult urban population are engaged in commercial sexual transactions.¹⁰ Studies from developed nations have found a high prevalence of self-harming behaviors in people engaged in transactional sexual activity.¹¹ There is also growing evidence suggesting that HIV-positive individuals from traditionally stigmatized groups report higher rates of violence exposure and suicidal ideation.^12,13 Female sex workers in India are a traditionally stigmatized group, with high prevalence of HIV¹⁰ and levels of stigma and violence that relate to the context of their work.¹⁴ Yet, despite substantial investigation of their reproductive and sexual health needs, there is virtually no information on suicide and its determinants among female sex workers from low- and middle-income countries.¹⁵As demonstrated in the hierarchical conceptual framework outlined in Figure 1,^4,5,9 we hypothesized that gender disadvantage, sex work, and health factors together with factors indicative of social disadvantage are distal determinants of female sex workers'' vulnerability to suicidal behaviors,^4,5,9,15 the effects of which would be mediated though poor mental health.³ We studied the burden of suicidal behaviors in a cross-sectional sample of female sex workers in Goa, India. We explored the association of sociodemographic factors, type of sex work, sexual health, and gender disadvantage, with and without measures of poor mental health, on suicide attempts in the past 3 months.Open in a separate windowFIGURE 1A conceptual framework for social risk factors for suicide among female sex workers in India.Note.

Male Perpetration of Intimate Partner Violence and Involvement in Abortions and Abortion-Related Conflict

Men aged 18 to 35 years (n = 1318) completed assessments of perpetration of intimate partner violence (IPV), abortion involvement, and conflict regarding decisions to seek abortion. IPV was associated with greater involvement by men in pregnancies ending in abortion and greater conflict regarding decisions to seek abortion. IPV should be considered within family planning and abortion services; policies requiring women to notify or obtain consent of partners before seeking an abortion should be reconsidered; they may facilitate endangerment and coercion regarding such decisions.Intimate partner violence (IPV) is a major public health issue that affects the lives and health of approximately 20% to 25% of adolescent and adult US women,^1,2 with women of reproductive age at greatest risk.^3,4 Major reproductive health concerns associated with experiences of IPV include unintended⁵ and rapid repeat pregnancies.^6–8 Given that unintended and unwanted pregnancies are the primary reason for seeking abortion,^7,9 abused women are thought to be more likely to experience abortion than are their nonabused counterparts.^10–12 Recent qualitative research suggests there is a broad role played by abusive male partners in controlling women''s reproductive health,^13–15 including attempts to control abortion-related decisions.^13,15 However, quantitative data on this issue have primarily been collected from women attending abortion services, which therefore precludes comparisons to women with no abortion history.^10–12 Given the increasing recognition of the role of male partners in controlling a woman''s reproductive health and decision-making, coupled with the continuing public debate concerning both women''s access to abortion and the role of family members in decisions regarding abortion (e.g., spousal consent),¹⁶ it is critical to understand to what extent abuse from male partners may relate to both women''s seeking abortion and coercion regarding abortion-related decisions. We examined the association of young adult men''s reports of perpetration of IPV and their participation in pregnancies ending in abortion as well as conflict surrounding abortion-related decisions.     

The association between perceived discrimination and obesity in a population-based multiracial and multiethnic adult sample

Objectives. We examined whether perceived chronic discrimination was related to excess body fat accumulation in a random, multiethnic, population-based sample of US adults.Methods. We used multivariate multinomial logistic regression and logistic regression analyses to examine the relationship between interpersonal experiences of perceived chronic discrimination and body mass index and high-risk waist circumference.Results. Consistent with other studies, our analyses showed that perceived unfair treatment was associated with increased abdominal obesity. Compared with Irish, Jewish, Polish, and Italian Whites who did not experience perceived chronic discrimination, Irish, Jewish, Polish, and Italian Whites who perceived chronic discrimination were 2 to 6 times more likely to have a high-risk waist circumference. No significant relationship between perceived discrimination and the obesity measures was found among the other Whites, Blacks, or Hispanics.Conclusions. These findings are not completely unsupported. White ethnic groups including Polish, Italians, Jews, and Irish have historically been discriminated against in the United States, and other recent research suggests that they experience higher levels of perceived discrimination than do other Whites and that these experiences adversely affect their health.It is estimated that 2 of every 3 adults in the United States are overweight or obese.^1,2 Obesity is a major risk factor for chronic health conditions, such as type 2 diabetes, coronary heart disease, hypertension, stroke, some forms of cancer, and osteoarthritis.³ Although it is widely accepted that high-fat diets and physical inactivity are preventable risk factors,⁴ obesity continues to increase.^1,2,5There is a growing interest in the relationship between psychosocial risk factors and excess body fat accumulation.^6–16 In particular, some evidence suggests that psychosocial stressors may play a role in disease progression in general and in excess body fat in particular.^7,8,17 The key factors underlying physiological reactions to psychosocial stress have not been completely elucidated, but McEwen and Seeman¹⁷ and others^7,18,19 posit that the continued adaptation of the physiological system to external challenges alters the normal physiological stress reaction pathways and that these changes are related to adverse health outcomes.^8,17,18,20 For example, in examining the association between psychosocial stress and excess body fat accumulation, Björntorp and others have suggested that psychosocial stress is linked to obesity, especially in the abdominal area.^7,8Perceived discrimination, as a psychosocial stressor, is now receiving increased attention in the empirical health literature.^21–24 Such studies suggest perceived discrimination is inversely related to poor mental and physical health outcomes and risk factors, including hypertension,^24,25 depressive symptoms,^26–28 smoking,^29–31 alcohol drinking,^32,33 low birthweight,^34,35 and cardiovascular outcomes.^36–38Internalized racism, the acceptance of negative stereotypes by the stigmatized group,³⁹ has also been recognized as a race-related psychosocial risk factor.⁴⁰ Recent studies have also suggested that race-related beliefs and experiences including perceived discrimination might be potentially related to excess body fat accumulation. Three of these studies^9,13,41 showed that internalized racism was associated with an increased likelihood of overweight or abdominal obesity among Black Caribbean women in Dominica⁴¹ and Barbados¹³ and adolescent girls in Barbados.⁹ These researchers posit that individuals with relatively high levels of internalized racism have adopted a defeatist mindset, which is believed to be related to the physiological pathway associated with excess body fat accumulation. However, Vines et al.¹⁶ found that perceived racism was associated with lower waist-to-hip ratios among Black women in the United States. Although the assessment of race-related risk factors varied across these studies, the findings suggest that the salience of race-related beliefs and experiences may be related to excess body fat accumulation.Collectively, the results of these studies are limited. First, because they examined the relationship between race-related beliefs and experiences and excess body fat only among women, we do not know if this relationship is generalizable to men.^13,16,41 Second, these studies only examined this relationship among Blacks, even though perceived unfair treatment because of race/ethnicity has been shown to be adversely related to the health of multiple racial/ethnic population groups in the United States^42–49 and internationally.^27,50–55 Third, none of the studies have examined the relationship between excess body fat accumulation and perceived nonracial/nonethnic experiences of interpersonal discrimination. Some evidence suggests that the generic perception of unfair treatment or bias is adversely related to health, regardless of whether it is attributed to race, ethnicity, or some other reason.^45,55,56 Fourth, none of these studies included other measures of stress. We do not know if the association between race-related risk factors and obesity is independent of other traditional indicators of stress.Using a multiethnic, population-based sample of adults, we examined the association of perceived discrimination and obesity independent of other known risk factors for obesity, including stressful major life events. Additionally, because reports of perceived racial/ethnic discrimination and non-racial/ethnic discrimination vary by racial/ethnic groups^24,45,46,57 and because Whites tend to have less excess body fat than do Blacks and Hispanics,^1,3 we examined the relationships between perceived discrimination and excess body fat accumulation among Hispanics, non-Hispanic Whites, and non-Hispanic Blacks.     

Social gradients in oral health in older adults: findings from the English longitudinal survey of aging

Objectives. We examined prospective associations between socioeconomic position (SEP) markers and oral health outcomes in a national sample of older adults in England.Methods. Data were from the English Longitudinal Survey of Aging, a national cohort study of community-dwelling people aged 50 years and older. SEP markers (education, occupation, household income, household wealth, subjective social status, and childhood SEP) and sociodemographic confounders (age, gender, and marital status) were from wave 1. We collected 3 self-reported oral health outcomes at wave 3: having natural teeth (dentate vs edentate), self-rated oral health, and oral impacts on daily life. Using multivariate logistic regression models, we estimated associations between each SEP indicator and each oral health outcome, adjusted for confounders.Results. Irrespective of SEP marker, there were inverse graded associations between SEP and edentulousness, with proportionately more edentate participants at each lower SEP level. Lower SEP was also associated with worse self-rated oral health and oral impacts among dentate, but not among edentate, participants.Conclusions. There are consistent and clear social gradients in the oral health of older adults in England, with disparities evident throughout the SEP hierarchy.The inverse linear relationship between socioeconomic position (SEP) and health is well established.^1–4 The uneven distribution of health across socioeconomic strata has been observed in both industrialized and less developed countries and for most common diseases and causes of death.^1,5–8 In most cases, the association between SEP and health is characterized by a linear graded pattern, with people in each lower SEP category having successively worse levels of health and dying earlier than those that are better off, a characteristic known as the social gradient in health.⁹Although there is clear and consistent evidence about the existence of the social gradient in working-age adults,^10,11 studies in older adults are less consistent, with some showing attenuation of the gradient^12,13 and others reporting that it persisted^14,15 or even increased¹⁶ in magnitude.Oral health is particularly important at older ages with tooth loss shown to be independently associated with disability and mortality.^17–20 Oral health status in older people is also an important determinant of nutritional status.²¹Socioeconomic disparities in oral health have been consistently demonstrated for various indicators, mostly clinical and disease related^22–31 but also subjective measures of oral health and quality of life.^30,32–38 Some of these studies have explicitly assessed the existence of an oral health gradient,^{23,25–31,34–37} but almost all were carried out on adolescents and adults, with very few focusing on older people.^33,36 These few relevant studies are cross-sectional and inconclusive and have used a limited number of SEP indicators (typically, education and occupational class), thereby hindering any comprehensive analysis on the relationship between SEP and oral health.We addressed the gap in the literature about the existence of an oral health gradient at older ages by examining the prospective associations between a wide range of SEP indicators (education, occupation, household income, household wealth, subjective social status [SSS], and childhood SEP) and various oral health outcomes (presence of natural teeth, self-rated oral health, and oral impacts) in a national sample of older adults from the English Longitudinal Survey of Aging (ELSA). We explored whether there are any significant socioeconomic inequalities in oral health among older people in England and, if so, whether these take the form of a gradient.     

Pathways and Correlates Connecting Latinos' Mental Health With Exposure to the United States

Objectives. We examined potential pathways by which time in the United States may relate to differences in the predicted probability of past-year psychiatric disorder among Latino immigrants as compared with US-born Latinos.Methods. We estimated predicted probabilities of psychiatric disorder for US-born and immigrant groups with varying time in the United States, adjusting for different combinations of covariates. We examined 6 pathways by which time in the United States could be associated with psychiatric disorders.Results. Increased time in the United States is associated with higher risk of psychiatric disorders among Latino immigrants. After adjustment for covariates, differences in psychiatric disorder rates between US-born and immigrant Latinos disappear. Discrimination and family cultural conflict appear to play a significant role in the association between time in the United States and the likelihood of developing psychiatric disorders.Conclusions. Increased perceived discrimination and family cultural conflict are pathways by which acculturation might relate to deterioration of mental health for immigrants. Future studies assessing how these implicit pathways evolve as contact with US culture increases may help to identify strategies for ensuring maintenance of mental health for Latino immigrants.It has been shown that Latino immigrants have better mental health than their US-born counterparts and non-Latino Whites, despite having disadvantaged socioeconomic status^1–3 (the “immigrant paradox”). It has also been shown that the mental health of immigrants declines over time in the host country³ (the “acculturation hypothesis”). Our findings from the National Latino and Asian American Study (NLAAS) on the prevalence of psychiatric disorders among Latinos in the United States indicate that foreign nativity is protective for some Latino groups (e.g., Mexicans) but not others (e.g., Puerto Ricans),⁴ implying that other factors besides nativity play a part in US Latinos'' risk of psychiatric disorders. Also, there is evidence that risk of psychopathology is the result of differences in immigrants'' length of residence in the United States and age at arrival. For example, Mexican immigrants in the United States for 13 years or more had higher rates of any mental health disorder, any mood disorder, alcohol abuse, and drug abuse than Mexican immigrants in the United States for fewer than 13 years.³ Findings from the NLAAS indicate that the longer that Latino immigrants remain in their country of origin, the less cumulative risk of onset of psychiatric disorders they experience, resulting in lower lifetime rates of disorders.⁵There is a lack of consensus about which aspects of US exposure are relevant for mental health.⁵ A number of hypotheses have linked years in the United States and mental illness among Latinos.³ US-born Latinos may have a weaker affiliation with traditional Latino values that buffer against mental illness than do Latino immigrants. When individuals come into contact with US culture, there may be negative outcomes such as increased intergenerational conflict,⁶ augmenting their risk for psychopathology. Although family factors have been hypothesized to be a protective factor for immigrant Latinos,^7,8 few empirical studies have actually tested this hypothesis with regard to psychiatric disorders. Another hypothesis is that US-born Latinos may have higher expectations for their quality of life than immigrant Latinos because of their citizenship status and their acquisition of skills similar to those possessed by non-Latino Whites.⁹ However, over time, these expectations may remain unfulfilled because of discrimination, resulting in social stress and declining levels of mental health.¹ Also, as time passes, immigrants may have perceptions of low social status¹⁰ that may be associated with higher risk of psychopathology.Other immigration-related factors could also affect adaptation experiences when integrating into the United States. Specifically, those arriving in the United States at early formative ages (0–10 years) may have weaker identification with Latino cultural values¹¹ and may confront significant pressure to acquire English as their dominant language.¹² English language dominance represents a strong cultural anchor for socially constructed meaning¹³ that may enable immigrants to join certain peer networks and not others. The neighborhoods where Latinos typically live are less safe than those inhabited by non-Latino Whites,¹⁴ which may increase Latinos'' likelihood of psychiatric disorders¹⁵ by increasing ambient hazards. In addition, exposure to racial/ethnic based discrimination^16,17 has been associated with negative mental health outcomes. The NLAAS study provides a unique opportunity to explore these pathways because these domains have been assessed for both Latino immigrants and US-born Latino respondents.We assessed the association of time in the United States with past-year risk for psychiatric disorder, with and without adjustment for potentially influential covariates. Then we tested different pathways explaining the link between time in the United States and psychiatric disorders.     

Migrants in Transit: The Importance of Monitoring HIV Risk Among Migrant Flows at the Mexico–US Border

We conducted a probability-based survey of migrant flows traveling across the Mexico–US border, and we estimated HIV infection rates, risk behaviors, and contextual factors for migrants representing 5 distinct migration phases. Our results suggest that the influence of migration is not uniform across genders or risk factors. By considering the predeparture, transit, and interception phases of the migration process, our findings complement previous studies on HIV among Mexican migrants conducted at the destination and return phases. Monitoring HIV risk among this vulnerable transnational population is critical for better understanding patterns of risk at different points of the migration process and for informing the development of protection policies and programs.Previous research indicates that Mexican labor migrants in the United States are at increased risk for HIV infection1–3 and may be a bridge population for increasing rates of HIV/AIDS in rural Mexico.4–6 The behavioral ecological model posits that health behaviors are influenced by a hierarchy of factors, including individual characteristics, features of the proximal context, and broader structural factors.7 The proximal context involves the physical and social conditions in which individuals live, work, learn, and play. The broader environment comprises political, social, and economic structures and cultural factors. Bidirectional influences exist across factors at the individual, contextual, and structural level, with interventions at the structural level having the most far-reaching public health impact.7 Mexican migrants tend to be male and young, have low levels of educational attainment, and report limited HIV prevention knowledge and condom use.8,9 Increased risk for HIV in migrants may result from the interplay between these individual characteristics and the broader contextual and structural factors in migration between Mexico and the United States.10Migration is a complex and multistage process involving 5 phases: predeparture, transit, destination, interception, and return.11 Different constellations of contextual and structural factors may influence risk behaviors for HIV infection among migrants at each of these stages. Research on HIV risk among migrants must cover the different phases involved in the migration process and identify risks as well as prevention and treatment opportunities associated with each of them.12 Much of our knowledge regarding HIV prevalence and behavioral risk factors among Mexican migrants has emanated from surveys conducted among receiving communities in the United States 1^,2^,13–15 and sending communities in Mexico.16^,17 These studies have covered the destination and return phases of migration.Mexican migrants in the United States (i.e., the destination) are exposed to contexts that may heighten their HIV risk. HIV prevalence rates are higher in the United States than in Mexico,18 increasing the probability of coming into contact with the virus. Furthermore, many migrants live in environments characterized by unbalanced gender composition (i.e., male overrepresentation) and limited family- and community-based social behavioral controls.19 They experience loneliness, geographic isolation, social exclusion,20 fear,21 poor living and working conditions, and limited access to health care, including access to HIV testing and other prevention services.2^,16^,19^,21–24 All these factors coalesce to increase the probability of risk behaviors for HIV, such as alcohol and drug use, sex with sex workers, and unprotected sex practices.9,10 Surveys in Mexican sending communities have documented higher rates of behavioral risk factors, such as a higher number of sexual partners and illicit drug use, but also increased rates of condom use, knowledge of HIV transmission, and HIV testing among return migrants, compared to nonmigrants in the same communities.16,25Little research has examined HIV risk among Mexican migrants during the predeparture, transit, and interception phases of the migration process. The same factors that may push migrants away from their sending communities, such as poverty,26 violence,27 and gender power unbalances,28,29 are also structural factors that may increase their HIV risk even before they leave these communities.30 The transit phase is defined as the period when migrants are between their place of origin and their destination.11 For most Mexican migrants, the northern border of Mexico is an intermediate point in their trajectory between the 2 countries. Northbound unauthorized and deported migrants may spend time in this transit location making arrangements to enter or reenter the United States. This region has been described as at heightened risk for infectious diseases such as HIV to occur and is characterized by “an economically disadvantaged population” and “a nexus for drug use, prostitution, and mobility.”^31(p428)Research with injecting drug users and sex workers in Mexican border cities has provided critical evidence of migration as a structural risk factor for HIV infection and substance use as well as the prevention needs of these high-risk groups.14,32 These studies have offered some insights into the potential risks among migrants in this intermediate migration context. Finally, migrants apprehended while trying to enter or after reaching the destination communities (i.e., interception phase) are at a particularly critical stage. Detention in immigration centers or prisons can have detrimental effects on migrants’ health.11 Interception may also be a marker of higher social vulnerability, as migrants who have less economic and social resources are more likely to experience this migration phase. A recent survey found higher rates of HIV infection and behavioral risk factors among deported Mexican migrants in Tijuana, Mexico, than among the US and Mexico populations.33 In general, knowledge concerning HIV risk among migrants at the 5 migration phases is fragmented, and the heterogeneity of sampling and data collection methodologies that previous studies have used creates challenges for comparing data on the different phases.There are an estimated 12 million Mexican migrants in the United States.34 Although not all migrants go through all 5 migration phases (some may never be intercepted, some may settle permanently in the region of destination and never return), many Mexican migrants go through 2 or more of these phases in their lifetime. Data on Mexican migration patterns indicate that circular migration (i.e., traveling back and forth between Mexico and the United States) is relatively common among Mexican migrants.34,35 About 29% of Mexican migrants are estimated to engage in circular migration,36 and 50% of undocumented migrants leave the United States within the first year of immigration.37 Proximity, social and political conditions, transportation costs, and cultural identity make Mexicans more likely to return to their home country than are migrants from other countries. Although the strengthening and stricter enforcement of border policies has lowered this trend in recent years, the incentives to emigrate out of Mexico have also increased.38 These circular migration patterns between Mexico and the United States result in sizable migrant flows traveling across the Mexican border.It is estimated that each year more than 600 000 Mexican migrants arrive in the United States, approximately 400 000 Mexican migrants return from the United States, and approximately 400 000 Mexican migrants are deported to Mexico.39,40 The same individual may arrive, return, or be deported more than once. In 2012, the net rate of Mexicans departing Mexico (mostly to the United States) and entering Mexico (most of whom are return migrants) was 41.9 and 14.3 per 1000, respectively.41 An estimated 300 000 Mexican migrants were admitted to a detention facility and repatriated by US immigration authorities,42 and an additional 266 000 unauthorized Mexican migrants were apprehended at the Mexican border.40 The volume and mix of migrants traveling across the Mexico–US border makes this region an important setting for binational monitoring of the mobile populations’ health. Such monitoring can further our understanding of HIV infection levels and of behavioral and environmental factors that contribute to HIV infection among Mexican migrants representing different phases and contexts of the migration process. Ongoing surveillance of this region can also reveal changes in HIV infection and behavioral risk factors among migrants on the move and inform the need for interventions to reduce HIV risk among Mexican migrants in sending, receiving, and intermediate communities.We estimated and compared the levels of HIV infection, risk behaviors, and contextual factors associated with different migration phases, using data from a survey of migrant flows who traveled across the Mexico–US border region and represented the different phases and geographic contexts of migration between Mexico and the United States.     

The California Endowment's Healthy Eating, Active Communities Program: A Midpoint Review

Objectives. We conducted a midpoint review of The California Endowment''s Healthy Eating, Active Communities (HEAC) program, which works in 6 low-income California communities to prevent childhood obesity by changing children''s environments. The HEAC program conducts interventions in 5 key childhood environments: schools, after-school programs, neighborhoods, health care, and marketing and advertising.Methods. We measured changes in foods and beverages sold at schools and in neighborhoods in HEAC sites; changes in school and after-school physical activity programming and equipment; individual-level changes in children''s attitudes and behaviors related to food and physical activity; and HEAC-related awareness and engagement on the part of community members, stakeholders, and policymakers.Results. Children''s environments changed to promote healthier lifestyles across a wide range of domains in all 5 key childhood environments for all 6 HEAC communities. Children in HEAC communities are also engaging in more healthy behaviors than they were before the program''s implementation.Conclusions. HEAC sites successfully changed children''s food and physical activity environments, making a healthy lifestyle a more viable option for low-income children and their families.Childhood obesity is at epidemic levels in the United States. More than 1 in 7 children and adolescents aged 6 to 17 years are considered obese.¹ Additionally, disparities in obesity rates exist among ethnic groups. Black, Hispanic, and Native American children and adolescents have higher rates of diabetes and obesity than do White children and adolescents.¹ Poor diet and inadequate physical activity have been linked to obesity and preventable chronic illnesses.^2,3 Overweight and obese children may develop a number of risk factors for chronic disease and are increasingly diagnosed with diseases that have historically had their onset in adulthood, such as type 2 diabetes, hypertension, and high cholesterol.⁴Most strategies to prevent or reduce childhood obesity have focused on individual behavior modification and pharmacological treatment, with limited success.⁵ Current research suggests that childhood dietary habits and physical activity levels are influenced by a variety of environmental factors,⁶ such as increasing portion sizes,^7–10 increasing availability of fast food and soft drinks,^11–20 availability of soda and unhealthy food on school campuses,^21–29 curtailment or elimination of physical education and recess in schools,³⁰ insufficient or inadequate parks and recreational facilities,³¹ public policy favoring personal transportation over mass transit,^32–39 limited access to healthy foods and ready availability of unhealthy foods,^37,40–44 and disproportionate advertising of low-nutrient-dense foods and sedentary activities to children and their families.^25,45–49Many of these factors are exacerbated in low-income communities, where healthy and affordable food options and safe opportunities for physical activity are noticeably absent.^40,42 These factors are contributing to high levels of diseases related to nutrition and physical activity among Black and Latino populations.^34,40,42,50A better understanding of the underlying factors that lead to obesity has led to the emergence of a new type of initiative that seeks to reduce childhood obesity by making environmental improvements that promote healthy eating and physical activity, rather than focusing on changing individual eating and activity patterns. Although this type of environmental intervention is relatively new, early results are encouraging.^51–53 It has been demonstrated that better access to healthy foods and opportunities for physical activity results in healthier diets and increased physical activity: people in the presence of supermarkets eat more fruits and vegetables,^40,42,54 and when a venue for physical activity is available, people are more likely to be physically active.^34,55To help prevent obesity and type 2 diabetes among children and adolescents, the Healthy Eating, Active Communities (HEAC) program was established to promote public health environmental change in 6 California communities. We conducted a midpoint review of HEAC''s progress to assess how well these communities were translating models for change into on-the-ground practices resulting in real improvements in the food and physical activity opportunities available to low-income children and families.     

Policy Support, Norms, and Secondhand Smoke Exposure Before and After Implementation of a Comprehensive Smoke-Free Law in Mexico City

Objectives. We assessed attitudes and beliefs about smoke-free laws, compliance, and secondhand smoke exposure before and after implementation of a comprehensive smoke-free law in Mexico City.Methods. Trends and odds of change in attitudes and beliefs were analyzed across 3 representative surveys of Mexico City inhabitants: before implementation of the policy (n = 800), 4 months after implementation (n = 961), and 8 months after implementation (n = 761).Results. Results indicated high and increasing support for 100% smoke-free policies, although support did not increase for smoke-free bars. Agreement that such policies improved health and reinforced rights was high before policy implementation and increased thereafter. Social unacceptability of smoking increased substantially, although 25% of nonsmokers and 50% of smokers agreed with smokers'' rights to smoke in public places at the final survey wave. Secondhand smoke exposure declined generally as well as in venues covered by the law, although compliance was incomplete, especially in bars.Conclusions. Comprehensive smoke-free legislation in Mexico City has been relatively successful, with changes in perceptions and behavior consistent with those revealed by studies conducted in high-income countries. Normative changes may prime populations for additional tobacco control interventions.Smoke-free policies can reduce involuntary exposure to toxic secondhand tobacco smoke (SHS), reduce tobacco consumption and promote quitting,^1,2 and shift social norms against smoking.^3–5 These policies are fundamental to the World Health Organization''s Framework Convention on Tobacco Control, an international treaty that promotes best-practices tobacco control policies across the world.⁶Evidence of successful implementation of smoke-free policies generally comes from high-income countries. Low- and middle-income countries increasingly bear the burden of tobacco use,⁷ however, and these countries may face particular challenges in implementing smoke-free policies, including greater social acceptability of tobacco use, shorter histories of programs and policies to combat tobacco-related dangers, and greater tolerance of law breaking.^8–10 There is a need for research that will help identify effective strategies for promoting and implementing smoke-free policies in low- and middle-income countries.Studies in high-income countries generally indicate that popular support for laws that ban smoking in public places and workplaces is strong and increases after such laws are passed.^11–15 Weaker laws that allow smoking in some workplaces can leave policy support unchanged.¹⁶ Policy-associated increases in support have been shown across populations that include smokers^{11,13,14,17,18} and bar owners and staff.^19,20 Beliefs about rights to work in smoke-free environments¹¹ and the health benefits of these environments²¹ have also been shown to increase with policy implementation. Support for banning smoking in all workplaces appears high in Latin American countries,²² but responses to smoke-free policies are less well known. In Uruguay, the first country in the Americas to prohibit smoking in all workplaces, including restaurants and bars,²³ support before the law was unknown. However, the level of support was high among both the general population²² and smokers²⁴ after the law''s implementation.Compliance with smoke-free laws in high-income countries has been good, particularly when laws apply across all workplaces, including restaurants and bars, and involve media campaigns. Self-reported declines in exposure in regulated venues^11,17,25 are consistent with findings from observational studies,^11,26 biomarkers of exposure,^11,25,27 and air quality assessments.^11,12Approximately 26% of Mexican adults residing in urban areas smoke.⁸ Most Mexicans recognize the harms of SHS and support smoke-free policies.^9,24,28,29 According to an opinion poll conducted before the August 2007 passage of a smoke-free law in Mexico City, about 80% of both Mexico City inhabitants and Mexicans in general supported prohibiting smoking in enclosed public places and workplaces.²⁸ In 2006, 60% of smokers reported that their workplace had a smoking ban, with Mexico City smokers reporting the lowest percentage of workplace bans at 37%.²⁴Mexico City''s smoke-free workplace law^30–32 initially allowed for designated smoking areas that were ventilated and physically separate.^22,33 Concerns about the inequity of this law for small business owners who could not afford to build designated smoking areas led the hospitality industry to support a comprehensive smoke-free law^31,32 that prohibited smoking inside all enclosed public places and workplaces, including public transport, restaurants, and bars. This law entered into force on April 3, 2008.Media coverage of the law was similar to that in high-income countries, pitting arguments about the government''s obligation to protect citizens from SHS dangers against arguments about discrimination toward smokers and the “slippery slope” of regulating behavior^4,32,34 (J. F. Thrasher et al., unpublished data, 2010). Most print media coverage was either positive or neutral, with much less coverage pitched against tobacco control policies.³⁴In the month before and after the law came into effect, the Mexico City Ministry of Health and nongovernmental organizations disseminated print materials and aired radio spots describing the dangers of SHS and the benefits of the law.³⁰ Community health promoters informed businesses about the law. From September through December 2008, a television, radio, print, and billboard campaign emphasized the law''s benefits.³⁵ We assessed, among Mexico City inhabitants, the prevalence of and increases in support, beliefs, norms, and compliance around the smoke-free law, as well as decreases in SHS exposure.     

The Long-Term Health Consequences of Relationship Violence in Adulthood: An Examination of Low-Income Women From Boston, Chicago, and San Antonio

Objectives. We examined the long-term health consequences of relationship violence in adulthood.Methods. Using data from the Welfare, Children, and Families project (1999 and 2001), a probability sample of 2402 low-income women with children living in disadvantaged neighborhoods in Boston, Massachusetts; Chicago, Illinois; and San Antonio, Texas, we predicted changes in the frequency of intoxication, psychological distress, and self-rated health over 2 years with baseline measures of relationship violence and a host of relevant background variables.Results. Our analyses showed that psychological aggression predicted increases in psychological distress, whereas minor physical assault and sexual coercion predicted increases in the frequency of intoxication. There was no evidence to suggest that relationship violence in adulthood predicted changes in self-rated health.Conclusions. Experiences with relationship violence beyond the formative and developmental years of childhood and adolescence can have far-reaching effects on the health status of disadvantaged urban women.Over the past 2 decades, numerous studies have examined the long-term health consequences of relationship violence during childhood. This body of research suggests that physical and sexual abuse in early life can be devastating to health in adulthood, contributing to poor mental^1–6 and physical health^3–5,7 and to higher rates of substance abuse.^5,6,8,9 These patterns are remarkably consistent across studies and notably persistent through the life course. In a recent study of more than 21 000 older adults, Draper et al.³ reported that physical and sexual abuse before 15 years of age is associated with poor mental and physical health well into late life.Although previous research has made significant contributions to our understanding of the lasting effects of abuse in early life, few studies have considered the long-term health consequences of relationship violence in adulthood. Our review of the literature revealed 5 longitudinal studies of relationship violence and health in adulthood. Not surprisingly, research suggests that women who experience relationship violence in adulthood are vulnerable to poor health trajectories, including increases in depressive symptoms,^10–12 functional impairment,^10,12 and alcohol consumption.^13,14Relationship violence is an important issue in all segments of society; however, studies consistently show that women of low socioeconomic status exhibit higher rates of intimate partner victimization than do their more affluent counterparts.^15–17 For example, Tolman and Raphael¹⁷ reported that between 34% and 65% of women receiving welfare report having experienced some form of relationship violence in their lifetime, and between 8% and 33% experience some form of relationship violence each year, levels that surpass those for women overall.¹⁸ Research also shows that residence in disadvantaged neighborhoods^19,20 and the presence of children in the household^21,22 may elevate the odds of relationship violence. Given their high violence-risk profile, attention must be directed to the patterns and health consequences of intimate partner victimization in the lives of disadvantaged urban women with children.^23–25Building on previous research, we used data collected from a large probability sample of low-income women with children living in low-income neighborhoods in Boston, Massachusetts, Chicago, Illinois, and San Antonio, Texas, to predict changes in the frequency of intoxication, psychological distress, and self-rated health over 2 years with measures of relationship violence in early life and adulthood and a host of relevant background variables. In accordance with previous research, we expected that intimate partner victimization in adulthood would predict increases in psychological distress and the frequency of intoxication and decreases in self-rated health over the study period.
