Cancer information disparities between U.S.- and foreign-born populations

Immigrant health is an important component of American public health. But relatively little is known about immigrants' cancer information use. Using the 2005 Health Information National Trends Survey (HINTS) data, this study examined potential disparities between foreign-born (n?=?563) and U.S.-born (n?=?4,830) populations in their access to and experience with cancer information. Logistic regressions showed that foreign-born Hispanics were less likely than the U.S.-born to have ever sought cancer information (adjusted odds ratio [OR]?=?.51). Foreign-born individuals overall were also less likely to have had somebody else look for cancer information for them (OR?=?.66). Compared with the U.S.-born, foreign-born individuals in general faced greater obstacles during the process of cancer information seeking (ORs?=?1.98-2.27). They were also less trusting of some important sources of health information (ORs?=?.50-.64), a pattern that was particularly pronounced among Hispanics (ORs?=?.20-.43). Implications of these disparities were explored through multiple linear regressions that revealed negative associations between cancer information use and undesirable cancer beliefs.     

Assessment of tuberculosis treatment completion in an ethnically diverse population using two data sources. Implications for treatment interventions

Many adolescents who are prescribed therapy for tuberculosis (TB) infection fail to complete it. This article presents the results of a demographic and epidemiological assessment of TB treatment completion in adolescent populations using (a) surveillance data from the Los Angeles Health County Department and (b) a prospective/retrospective medical chart review from targeted clinics. Patients who did not complete the 6-month recommended medical treatment for latent tuberculosis therapy (LTBI) averaged 13 weeks in care. Younger age (OR = 1.15; 95% CI 1.03-1.29), birth in the United States (OR = 1.92; 95% CI 1.14-3.22, compared to Mexico), and Asian ethnicity were associated with completion of care. In multiple logistic regression analysis, age (OR = .88; 95% CI .78-.98) and Latino ethnicity (OR = .53; 95% CI .29-.95) remained significant predictors of completion of treatment. These findings indicate the need for age-specific educational reinforcement and cultural differentials in completing care for LTBI.     

Challenges to tuberculin screening and follow-up in an urban Aboriginal sample in Montreal, Canada

We sought to describe the prevalence and predictors of tuberculin skin test (TST) reactors in a high-risk sample of urban Aboriginal people, and to evaluate adherence to medical evaluation and latent tuberculosis infection (LTBI) treatment among those with TST reactivity. Of the 164 participants tested, 86% returned for TST reading. Positive TST reactions (>or=10 mm) were observed in 17.7% (25/141, 95% CI 11.4-24.0) of participants, and were associated with older age (OR per 10 year increase 1.8, 95% CI 1.2-2.7) and Inuit Aboriginal group (OR 2.8, 95% CI 1.1-7.3). Only four participants presented for evaluation, of whom one initiated and none completed LTBI treatment. Tuberculin screening in this population can be an effective strategy for identifying TST reactive individuals; however, screening efforts will have minimal impact without additional efforts in this high-risk group.     

Smoking prevalence and correlates among Chinese- and Filipino-American adults: findings from the 2001 California Health Interview Survey

OBJECTIVES: We report prevalence rates and correlates of cigarette smoking among a population-based sample of Chinese- and Filipino-American adults together with rates found in other racial/ethnic groups in California. METHODS: All analyses are based on the 2001 California Health Interview Survey. RESULTS: The proportion of current smokers among males was lowest among Chinese Americans (14%), followed by Non-Hispanic Whites (19%), Hispanics (20%), African Americans (22%), Filipino Americans (24%), American Indians/Alaska Natives (29%), and Pacific Islanders (32%). The proportion of current smokers among females was lowest among Chinese Americans (6%), followed by Hispanics (8%), Filipino Americans (11%), Non-Hispanic Whites (17%), African Americans (20%), Pacific Islander (21%), and American Indians/Alaska Natives (32%). Smoking rates were higher among foreign-born versus U.S.-born Asian males. CHIS data show an opposite effect among Asian women: acculturation to the U.S. is associated with increased smoking prevalence rates. Multivariate analyses with Chinese and Filipino respondents showed that the likelihood of smoking varied among foreign-born versus U.S.-born men (OR 2.59 for Chinese, 1.42 for Filipino, 2.01 for all Asian men combined) and for foreign-born versus U.S.-born women (OR 0.41 for Chinese, 0.38 for Filipino, and 0.59 for all Asian women combined). CONCLUSION: Public health intervention efforts should take into account Asian ethnic subgroup, gender, and acculturation status in targeting high-risk smoking groups.     

Individual- and neighborhood-level contextual factors are associated with Mycobacterium tuberculosis transmission: genotypic clustering of cases in Michigan, 2004–2012

PurposeUsing genotyping data of Mycobacterium tuberculosis isolates from new cases reported to the tuberculosis (TB) surveillance program, we evaluated risk factors for recent TB transmission at both the individual- and neighborhood- levels among U.S.-born and foreign-born populations.MethodsTB cases (N = 1236) reported in Michigan during 2004 to 2012 were analyzed using multivariable Poisson regression models to examine risk factors for recent transmission cross-sectionally for U.S.-born and foreign-born populations separately. Recent transmission was defined based on spoligotype and 12-locus-mycobacterial interspersed repetitive unit–variable number tandem repeat typing matches of bacteria from cases that were diagnosed within 1 year of each other. Four classes of predictor variables were examined: demographic factors, known TB risk factors, clinical characteristics, and neighborhood-level factors.ResultsOverall, 22% of the foreign-born cases resulted from recent transmission. Among the foreign-born, race and being a contact of an infectious TB case were significant predictors of recent transmission. More than half (52%) of U.S.-born cases resulted from recent transmission. Among the U.S.-born, recent transmission was predicted by both individual- and neighborhood-level sociodemographic characteristics.ConclusionsInterventions aimed at reducing TB incidence among foreign-born should focus on reducing reactivation of latent infection. However, reducing TB incidence among the U.S.-born will require decreasing transmission among socially disadvantaged groups at the individual- and neighborhood- levels. This report fills an important knowledge gap regarding the contemporary social context of TB in the United States, thereby providing a foundation for future studies of public health policies that can lead to the development of more targeted, effective TB control.     

The “Latina Epidemiologic Paradox”: Contrasting Patterns of Adverse Birth Outcomes in U.S.-Born and Foreign-Born Latinas

BackgroundThe “Latina epidemiologic paradox” postulates that despite socioeconomic disadvantages, Latina mothers have a lower risk for delivering low birth weight (LBW) babies than non-Latina Whites. However, these patterns may be changing over time and may differ depending on the mother's birthplace and legal status in the United States. This study investigates differences in risk for three birth outcomes among Whites, U.S.-born Latinas, and foreign-born Latinas.MethodsWe undertook a cross-sectional study of rates of LBW, preterm, and small-for-gestational-age (SGA) births among 196,617 women delivering live, singleton births in Utah from 2004 to 2007. Each group was compared using logistic regression.ResultsU.S.-born Latinas had a similar or greater risk for all three outcomes when compared with Whites. Foreign-born Latinas had lower risk for preterm birth (odds ratio [OR], 0.85; 95% confidence interval [CI], 0.80–0.90) compared with Whites, but not for LBW and SGA; foreign-born Latinas had a lower risk for LBW (OR, 0.82; 95% CI, 0.74–0.92), preterm birth (OR, 0.81; 95% CI, 0.74–0.89), and SGA (OR, 0.91; 95% CI, 0.83–0.99) compared with U.S.-born Latinas. Among foreign-born Latinas only, there was no difference in risk between documented (i.e., those who had a legal social security number) and undocumented women for LBW, preterm birth, or SGA.ConclusionsThese data support the existence of a variation of the “Latina paradox” among Latinas according to birthplace, where U.S.-born Latinas do not experience better birth outcomes than Whites, but foreign-born Latinas experience better birth outcomes for several endpoints compared with U.S.-born Latinas. Prevention efforts may prove more effective by considering the different composition of risk factors among foreign- and U.S.-born Latina populations.     

Deconstructing a disparity: explaining excess preterm birth among U.S.-born black women

Purpose

To determine components of excess preterm birth (PTB) rates for U.S.-born black women relative to both foreign-born black women and U.S.-born white women attributable to differences in observed sociodemographic, behavioral, and medical risk factors.

A Comparison of Nonfatal Unintentional Injuries in the United States Among U.S.-Born and Foreign-Born Persons

The objective of this research was to compare the risk of nonfatal unintentional injuries between foreign-born and U.S.-born persons. Cross-sectional, nationally representative data were used from the 2000–2003 National Health Interview Survey to compare the risk of injury between 62,267 foreign-born and 322,200 U.S.-born persons. Nonfatal unintentional injuries occurring during the three months prior to the interview were compared by age, gender, education, poverty status, region of residence, family size, and health insurance coverage status. There were a total of 7,654 injured persons with U.S.-born persons having a weighted injury prevalence of 2.3% (95% confidence interval [CI]: 2.2, 2.4) and foreign-born persons having a weighted injury prevalence of 1.2% (95% CI: 1.0, 1.3). With the U.S.-born population as the reference and while controlling for sociodemographic characteristics, the odds ratio of injury risk was 0.54 (95% CI: 0.48, 0.62) for the foreign-born population. Transportation-related injuries occurred more frequently among foreign-born persons than among U.S.-born persons (23.7%, 95% CI: 19.7, 28.3 vs. 15.0%, 95% CI: 14.0, 16.2, respectively). This research is the first step in determining the morbidity from unintentional injuries among the foreign-born population in the U.S.     

The role of health insurance on Pap smear and mammography utilization by immigrants living in the United States

BACKGROUND: Nearly half of recent immigrants to the United States lack health insurance. Access to cancer screening services for this group is problematic. We examine the role of health insurance and having a usual source of care (USC) on Pap smear and mammography utilization by immigrant women using a nationally representative sample. METHODS: We used a telephone survey that oversampled racial and ethnic minorities. We analyzed data on 3,622 women age 18-70. We classified the 822 foreign-born women as recent immigrants if they had resided in the United States for under 10 years; LT immigrants were those with a longer tenure. RESULTS: Among recent immigrants, 73% and 78% (SE 4%) reported a Pap smear or mammogram, respectively, in the previous 2 years versus 89% and 89% of U.S.-born women (P < 0.05 for both comparisons). Among those with insurance or a USC, differences in screening between recent immigrants and U.S.-born women were four percentage points or less and not statistically significant. However, uninsured recent immigrants were less likely than uninsured U.S.-born women to have Pap smears [60% (SE 7%) versus 71%, P < 0.05]. Adjusting for differences in sociodemographics, health attitudes or beliefs, patient or provider communication, and the medical care environment, insurance remained the strongest predictor of screening. CONCLUSION: Disparities in screening were greatly attenuated among the insured population. Increasing awareness of available safety net sources of care may also improve cancer screening among uninsured recent immigrants.     

Incidence of TB in inmates with latent TB infection: 5-year follow-up

BACKGROUND: Inmates are a high-risk population for tuberculosis (TB) control efforts, including treatment for latent tuberculosis infection (LTBI). Completion of therapy after release has been poor. The goal of this study was to evaluate therapy completion and active disease over 5 years in a cohort of inmates. METHODS: The sample was from a completed randomized trial in 1998-1999 of education or incentive versus usual care to improve therapy completion after release from the San Francisco County Jail. Records from the jail, the County Tuberculosis Clinic, and the California TB Registry were used to measure therapy completion and development of active TB. Analyses were conducted in 2005. RESULTS: Of a total 527 inmates, 31.6% (n=176) completed therapy, of whom 59.7% (n=105) completed it in jail. Compared with the U.S.-born, foreign-born inmates residing in the United States for < or =5 years were less likely to complete the therapy (adjusted odds ratio [AOR]=0.49, 95% confidence interval [CI]=0.28-0.85), and those with more education were more likely to complete the therapy (AOR=1.06, 95% CI=1.01-1.12). Three subjects developed active TB in the 5 years of follow-up, resulting in an annual rate of 108 per 100,000. Compared with California rates, subjects were 59 times as likely to develop active TB (standardized morbidity ratio of 59.2, 95% CI=11.2-145.1). None had completed therapy, none were new immigrants, and two were known to be HIV-positive at diagnosis. CONCLUSIONS: Completion of therapy for LTBI is a challenge, but the active TB seen in this jail cohort emphasizes the importance of continued efforts to address TB risk in this population.     

Offending Behavior,Drug Use,and Mental Health Among Foreign-Born versus U.S. Born Latino Criminal Justice Clients

Little is known about the offending behavior and recidivism factors of Latinos by nativity (U.S. born, foreign-born). The present study focused on Latinos in community corrections (n?=?201) in Miami, Florida, and examined differences in criminal activity, drug use, and mental health by nativity. Data were collected utilizing convenience sampling between June 2014 and December 2015. The research question was: what are the offending, drug use, and mental health histories of Latinos involved in community corrections? Participants were mostly male (n?=?120; 59.7%), White (n?=?105; 52.2%), and Cuban (n?=?97; 48.3%). U.S. born community corrections clients (n?=?141) were more likely to report more lifetime and recent criminal activity; and more likely to report lifetime and recent drug use behavior than foreign-born Latinos (n?=?60). No differences were found in recent mental health. Correctional healthcare should tailor services such as substance abuse treatment differently toward U.S. born and foreign-born Latinos.     

A national study of socioeconomic status and tuberculosis rates by country of birth, United States, 1996-2005

ABSTRACT: BACKGROUND: Tuberculosis (TB) in developed countries has historically been associated with poverty and low socioeconomic status (SES). In the past quarter century, TB in the United States has changed from primarily a disease of native-born to primarily a disease of foreign-born persons, who accounted for more than 60% of newly-diagnosed TB cases in 2010. The purpose of this study was to assess the association of SES with rates of TB in U.S.-born and foreign-born persons in the United States, overall and for the five most common foreign countries of origin. METHODS: National TB surveillance data for 1996-2005 was linked with ZIP Code-level measures of SES (crowding, unemployment, education, and income) from U.S. Census 2000. ZIP Codes were grouped into quartiles from low SES to high SES and TB rates were calculated for foreign-born and U.S.-born populations in each quartile. RESULTS: TB rates were highest in the quartiles with low SES for both U.S.-born and foreign-born populations. However, while TB rates increased five-fold or more from the two highest to the two lowest SES quartiles among the U.S.-born, they increased only by a factor of 1.3 among the foreign-born. CONCLUSIONS: Low SES is only weakly associated with TB among foreign-born persons in the United States. The traditional associations of TB with poverty are not sufficient to explain the epidemiology of TB among foreign-born persons in this country and perhaps in other developed countries. TB outreach and research efforts that focus only on low SES will miss an important segment of the foreign-born population.     

Personal and Cultural Influences on Diabetes Self-Care Behaviors Among Older Hispanics Born in the U.S. and Mexico

Older Hispanics are disproportionately affected by diabetes, but little is known about predictors of diabetes self-care among this group. This study compared the magnitude of three self-care behaviors (diet, physical activity (PA), and glucose monitoring) among older Hispanics with type 2 diabetes born in the United States (n?=?59) to those born in Mexico (n?=?179), and investigated the influence of personal and health indicators on each self-care behavior. Findings were based on data drawn from convenience sample data collected with a questionnaire. Self-care behaviors were moderately practiced (39.5–45.8?%) with no significant differences by nativity. Mexico-born seniors were less linguistically acculturated (P?<?0.001). Being female (OR?=?2.41) and PA levels (OR?=?2.62) were significantly associated with diet. Being female (OR?=?3.24), more educated (OR?=?3.73), U.S.-born (OR?=?2.84), and receiving diabetes education (OR?=?3.67) were associated with PA. Diabetes education (OR?=?2.41) was associated with glucose monitoring. Although acculturation influenced only PA and no other behaviors, personal and cultural factors require further investigation to design diabetes management strategies for Hispanic seniors at the border region.     

Social networks,migration, and HIV testing among Latinos in a new immigrant destination: Insights from a qualitative study

Latinos in the U.S. are disproportionately affected by HIV and are more likely than non-Latinos to present with a late diagnosis, which delays engagement in HIV care and treatment. Social networks may provide normative influence and social support for HIV testing, but a contextualised understanding of networks is needed in order to maximise these social resources. We conducted qualitative interviews with foreign-born Latino men and transgender women (n?=?17) in a new immigrant destination to explore their social networks. Most participants described having smaller social networks after migrating. Networks included both local and transnational ties, but most participants had few close ties. Contextual factors including stigma and geographic dispersion limited the re-construction of networks with close ties after migration. HIV testing was not a common topic of discussion with social network ties. Efforts to improve early uptake of HIV testing among Latino immigrants may benefit from engaging with social networks, but such efforts need to address how the context in which networks operate enables access to testing.     

Cysticercosis-related deaths, California

Cysticercosis is an increasingly important disease in the United States, but information on the occurrence of related deaths is limited. We examined data from California death certificates for the 12-year period 1989-2000. A total of 124 cysticercosis deaths were identified, representing a crude 12-year death rate of 3.9 per million population (95% confidence interval [CI] 3.2 to 4.6). Eighty-two (66%) of the case-patients were male; 42 (34%) were female. The median age at death was 34.5 years (range 7-81 years). Most patients (107, 86.3%) were foreign-born, and 90 (72.6%) had emigrated from Mexico. Seventeen (13.7%) deaths occurred in U.S.-born residents. Cysticercosis death rates were higher in Latino residents of California (13.0/106) than in other racial/ethnic groups (0.4/106), in males (5.2/106) than in females (2.7/106), and in persons >14 years of age (5.0/106). Cysticercosis is a preventable cause of premature death, particularly among young Latino persons in California and may be a more common cause of death in the United States than previously recognized.     

Mind the gap: parents' citizenship as predictor of Latino children's health insurance

Parents' citizenship appears to be correlated with high rates of uninsurance and low rates of job-based insurance among Latino citizen children in families headed by citizens and non-citizens. Few studies have examined the direct relationship between parents' citizenship and children's insurance status. Data for U.S.-born Latino and non-Latino white children ages 0-18 years in working two-parent households obtained from the March 2001 Current Population Survey were analyzed. Results from logistic regressions were adjusted for a design effect to account for survey design. After controlling for other sociodemographic and employment characteristics, only Latino children in families headed by non-citizen couples are more likely to be uninsured and less likely to have employer-based insurance than others in the dataset. Even controlling for non-citizen parents' duration in the U.S., citizenship status of the head of household predicts children's coverage. Latino children are more likely to have health insurance if they have at least one citizen parent. Continued and varied efforts are needed to promote coverage among U.S.-born Latino children.     

Treatment for latent TB in correctional facilities: a challenge for TB elimination

BACKGROUND: To eliminate tuberculosis (TB) in the United States, more information is needed on how to gain access to difficult-to-reach, high-risk populations to evaluate people who would benefit from treatment for latent TB infection (LTBI). METHODS: A field study was conducted of people at risk for co-infection with TB and the human immunodeficiency virus (HIV) and to demonstrate that treating LTBI in inmates is feasible. Inmates were tested for LTBI using the Mantoux tuberculin skin test (TST). Outcomes measured were skin test results and the start and completion of treatment for LTBI. RESULTS: In 49 correctional facilities in 12 states, 198102 inmates had a skin test read. The mean skin test positivity rate among inmates was 17.0%. Of those who had a known HIV test result, 14.5% tested HIV positive. Inmates with a positive TST were 4.2 times more likely than those with a negative TST to be HIV infected (95% confidence interval [CI]=3.9-4.4). Therapy for LTBI was completed in 55.9% of patients started on treatment. Patients who were HIV positive and started on a 12-month treatment regimen were less likely than HIV-negative patients (40.0% vs 68.1%, respectively) to complete treatment (odds ratio [OR]=0.24, 95% CI=0.20-0.28). Patients treated in jails were less likely than those treated in prisons (33.6% vs 57.7%, respectively) to complete treatment (OR=0.29, 95% CI=0.26-0.32). CONCLUSIONS: Correctional facilities offer a venue for identifying and treating high-risk individuals for LTBI. However, completing treatment is more problematic in jails than in prisons.     

Diagnosis of latent tuberculosis infection in candidates for kidney transplantation (comparison of two tests)

It is assumed that about 10% of individuals infected with Mycobacterium tuberculosis develop tuberculosis. The rate of tuberculosis in solid organ transplant recipients has been estimated to be 50-fold higher than in the general population. Candidates for solid organ transplantation are routinely screened for latent tuberculosis infection (LTBI). In this study we aimed to compare Tuberculin Skin Test (TST) with QuantiFERON-TB Gold In-Tube (QFT) for the detection of LTBI in candidate for kidney transplantation. Between October 2009 and November 2010, 64 candidates for kidney transplant who referred to the transplant clinic in Imam Khomeini Hospital, were enrolled in the study. Patients were screened for LTBI with both QFT and TST. Concordance between two test results and variables associated with test discordance were assessed. The mean age of patients was 38.5 years (range 16-65); female/male ratio was 26/38. Positive results were found in 21.9% and 21.9%, by TST and QFT, respectively. Four patients (6.3%) had indeterminate QFT. Overall agreement between QFT and TST was 75% (k=0.28 and P=0.028). BCG vaccination and past positive TST were not associated with positive QFT result (P=0.13 and P=0.09 respectively). Overall agreement between test results was fair. Comparison among test results showed that TST andQFT can be used interchangeably for latent TB screening in kidney transplant candidates. The decision to select QFT or TST will depend on the purpose of testing and resource availability.     

Patients' reports about medical doctors' inquiries on their mental health: do generational status, ethnicity and mental health/substance use disorders matter?

Immigrants are less likely than others to use mental health (MH) services. Physicians' limited time often precludes inquiry about MH. This study investigated the influence of generational status, ethnicity, and mental/substance use disorders on physicians' inquiries about Asian American (AA) MH. Data from the National Latino and Asian American Study were analyzed (n=1,853). The outcome was past year physician's inquiry regarding MH. Results revealed that AA with U.S.-born parents had significantly greater odds compared to AA born outside the U.S. to report that their doctors inquired about their MH (OR=218, 95% CI: 1.28, 3.73). Past year mental/substance use disorder increased the odds of AA reporting that their doctors inquired about their MH (OR=8.41; 95% CI: 3.28, 21.66). This increase differed by ethnicity, with Chinese less affected than Vietnamese (OR=0.17; 95% CI: 0.05, 0.59). The reasons for these associations warrant further exploration.
