Objectives: This study examines the relationship among pregnancy intention and attitudes, inconsistent contraceptive use, and plans for potential pregnancy among 311 women who presented at local health departments to seek a pregnancy test and for whom a pregnancy would be unintended. Methods: Women were surveyed prior to receiving pregnancy tests. Pregnancy intention was measured using traditional classifications of mistimed and unwanted pregnancies. Frequency distributions and chi-square tests were computed to examine and compare rates of happiness about the pregnancy among women with mistimed or unwanted pregnancy and to compare rates of inconsistent contraceptive use and plans for the pregnancy by intention and level of happiness. Results: Although all of the women selected for our sample stated that their pregnancies would be unintended, almost half (46%) were inconsistent contraceptive users. Further, 48% reported that they would be somewhat or very happy about a pregnancy. The proportion of women who were uncertain about the future of a pregnancy and who considered adoption or abortion was highest among those for whom a potential pregnancy was mistimed and who were unhappy about the pregnancy. Conclusions: Differentiating between pregnancy intention and happiness has practice implications for family planning and prenatal providers. Additional research should further elaborate these distinctions.  相似文献

BackgroundPrevious research has established that women accumulate less moderate-to-vigorous physical activity (MVPA) than men. To date, however, little is known about the gender differences in device-based activity patterns of sedentary behavior (SB) and light-intensity physical activity (LPA). We aimed to compare time spent in SB and different intensities of physical activity taking into account of co-dependence of time use domains.MethodsThis cross-sectional study was conducted in Suttu town, Hokkaido, Japan. Data were analyzed from 634 Japanese adults (278 men, aged 19–92 years) who provided valid accelerometer (HJA-750C) data. Gender differences in activity behavior patterns were tested using multivariate analysis of covariance (MANCOVA) based on isometric log-ratio transformations of time use, adjusting for age. We also developed bootstrap percentile confidence intervals (CI) to support the interpretation of which behavior differed between genders.ResultsOverall, participants had percent time spent in SB, LPA, MVPA during wearing time (mean, 14.8 hours) corresponding to 53.9%, 41.7%, and 4.4% of wearing time, respectively. Activity behavior patterns differed significantly between genders after controlling for time spent in all activities. Women spent relatively 13.3% (95% CI, 9.9–15.9%) less time in SB and 19.8% (95% CI, 14.9–24.6%) more time in LPA compared to men. The difference of time spent in MVPA was not statistically significant.ConclusionsIn contrast with previous studies, our findings suggest that Japanese women are more physically active than men when all intensities of activities are considered. Given the health benefits of LPA, evaluating only MVPA may disproportionately underestimate the level of physical activity of women.Key words: accelerometry, exercise, sedentary lifestyle, middle-aged, physical activity  相似文献

Objective. We examined adverse birth outcomes among Mexican-Americans to determine the effect of country of maternal birth, a measure of acculturation. Design. We conducted a retrospective cohort analysis of birth outcomes among 4800 Mexico-born and 4800 US-born Mexican-American women using Washington State birth certificate data from 1989 to 1994. Length of residence at current address was used to help refine our measure of acculturation. Results. US-born women had a slightly increased risk of preterm birth relative to Mexico-born women [relative risk (RR) 1.18, 95% confidence interval (CI) 1.04-1.33]. Among Mexico-born women, the risk of preterm birth increased with greater duration of current residence. Conclusions. US-born Mexican-American women had a slightly increased risk of preterm birth despite having more adequate prenatal care, more education, and higher socioeconomic indicators. This may be due to acculturation factors, such as earlier pregnancy, loss of social support systems, and increased smoking or alcohol use. Reducing this risk depends on recognition among health care workers and policy-makers of the potential influence of acculturation on health in this population .  相似文献

This paper explores associations among the vulnerabilities of being female, being a member of a minority group, and being a drug abuser in homeless women’s hospitalizations. It uses a 1997 probability survey of 974 homeless females age 15–44 in Los Angeles. In unadjusted analyses, whites were more likely than other ethnic minority groups to be hospitalized, and drug abusers were more likely to be hospitalized than non-drug abusers. Multiple logistic regression analyses indicated that factors associated with hospitalization differed considerably among the ethnic and drug-abuse subgroups. For example, ethnic disparities in inpatient health care were found for drug-abusing women, but not for those who did not abuse drugs. Pregnancy was the only important determinant of hospitalization in all subgroups (OR, 2.9–17.4). Preventing unintended pregnancy appears to be the most inclusive means of reducing hospitalization and attendant costs among homeless women. The authors dedicate this paper in memory of and with great fondness for Douglas Longshore, PhD, our co-investigator and beloved colleague, who always reminded us to search for the truth and that, rather than simply “controlling” for other variables in analyzing ethnicity, to actively use those other variables in the model to explain the effect of ethnicity. Such analyses might suggest policy levers to improve the health of at-risk populations.  相似文献

Against a backdrop of scant literature on commonalities and differences among diverse groups of menopausal women within the United States, and little attempt by scholars in any country to study the ways in which both privilege and oppression can shape women's ideas and experiences of menopause, in this study, 61 menopausal women of varied racial–ethnic and class locations in a Midwestern state were asked about the different meanings and experiences of menopause. African American women and Chicanas, particularly working-class women, viewed menopause as a positive experience, whereas many middle-class European American women discussed more negative feelings. Women of color were more likely than European Americans to report talking about menopause with same-race, same-sex friends only. While women of color discussed their knowledge of European American women's menopause, the latter lacked knowledge of other women's experiences. Women's lived experiences with privilege and oppression also surfaced in the interviews. The authors argue that when scholars listen to how women discuss menopause experiences, commonalities among women by gender, and differences among women by race, and class are exposed. The presence of racial–ethnic differences in these pilot data suggests the importance of more comparative studies on reproductive aging both in the United States and abroad.  相似文献

Most research concerning clients of commercial sex workers (CSWs) relies upon CSW reports of client characteristics and behavior. We describe correlates of ever purchasing sex among 3,829 men from three cities: São Paulo, Brazil; Cuernavaca, Mexico; and Tampa, USA. A computer-assisted self-interview collected data on demographics and sexual behavior. There were significant site differences—26.5 % paid for sex in São Paulo, 10.4 % in Cuernavaca, and 4.9 % in Tampa. In all cities, men who had sex with men and women (versus sex with women only) were more likely to have ever paid for sex. In São Paulo and Cuernavaca, CSW clients were older, had higher educational attainment, and were less likely to be married. In Tampa, older age was associated with being a CSW client but not education and marital status. In São Paulo and Cuernavaca, CSW clients had more partners than men who had never paid for sex. In São Paulo, CSW clients initiated vaginal sex at an earlier age, while in Cuernavaca they were more likely to self-report a sexually transmitted infection. CSW clients varied with respect to demographics across the three cities while the association between paying for sex and risky sexual behavior seems to be somewhat conserved. These findings suggest that interventions among CSW clients should focus on condom use with commercial and non-commercial partners as these men may be at increased risk for transmitting and acquiring sexually transmitted infections to and from their sex partners. Better understanding of client characteristics is needed for targeting interventions and creating culturally appropriate content.  相似文献

This article considers the scientific evidence on the prevalence and management of verified lactose intolerance and the growing misperception that dairy foods should be avoided because ethnic populations cannot tolerate them. Healthcare professionals, in particular, must understand why eliminating dairy foods is rarely necessary and is generally undesirable. The genetically programmed ability to digest the milk sugar lactose normally declines throughout childhood in all ethnic groups. Only rarely does lactase nonpersistence result in verifiable lactose intolerance. The intolerance-gastrointestinal symptoms, such as diarrhea, bloating, and abdominal cramping-is easily managed when it occurs and is not a barrier to the consumption of 2 to 3 servings of calcium-rich dairy foods, as encouraged by the Dietary Guidelines for Americans.  相似文献

This qualitative study examined sex work among internally displaced male and transgender female sex workers in Bogotá, Colombia. Internal displacement has occurred in Colombia as a result of decades of conflict among armed groups and has created large-scale migration from rural to urban areas. Informed by the polymorphous model of sex work, which posits that contextual conditions shape the experience of sex work, we examined three main research questions. The first dealt with how internal displacement was related to the initiation of sex work; the second concerned the effect of agency on sex worker satisfaction; and the third examined how sex work in this context was related to HIV and other risks. Life history interviews were conducted with 26 displaced individuals who had done sex work: 14 were men who have sex with men and 12 were transgender women (natal males). Findings revealed that many participants began doing sex work in the period immediately after displacement, because of a lack of money, housing, and social support. HIV risk was greater during this time due to limited knowledge of HIV and inexperience negotiating safer sex with clients. Other findings indicated that sex workers who exerted more control and choice in the circumstances of their work reported greater satisfaction. In addition, we found that although many sex workers insisted on condom use with clients, several noted that they would sometimes have unprotected sex for additional money. Specific characteristics affecting the experience of sex work among the transgender women were also discussed.  相似文献

We used an Internet-based questionnaire to investigate whether viewing pornography depicting unprotected anal intercourse (UAI) was associated with engaging in UAI in a sample of 821 non-monogamous men who have sex with men (MSM). In the 3 months prior to interview, 77.2% viewed pornography depicting UAI, 42.6% engaged in insertive UAI, and 38.9% engaged in receptive UAI. Polytomous logistic regression of the 751 subjects who provided data on pornography viewing showed significantly elevated odds ratios for having engaged in receptive UAI, insertive UAI, and both receptive and insertive UAI associated with increasing percentage of pornography viewed that depicted UAI. We also found independently significant associations of engaging in UAI with age, use of inhalant nitrites, and HIV status. Although the data cannot establish causality, our findings indicate that viewing pornography depicting UAI and engaging in UAI are correlated. Further research is needed to determine if this observation may have utility for HIV prevention.  相似文献

Changes in psychosocial risk and protective factors associated with the onset of substance use were examined in a sample of 556 urban public school sixth graders. General linear modeling analyses indicated that students who did not use substances by the end of sixth grade consistently had higher scores on protective factors than did students who were already using substances at the beginning of sixth grade. Students who began to use during the school year were in flux with scores similar to nonusers at Time 1 and scores closer to early users by Time 2. These findings suggest that interventions which focus on skill enhancement during the transition to middle school may be effective at delaying the onset of substance use. Editors' Strategic Implications: The authors find the same protective factors in this urban, primarily African American sample that are typical in suburban, White samples. Developmentalists and school officials will find interesting the changing effects of protective factors against early substance use during the transitional sixth grade year.  相似文献

Monetary incentives are increasingly used to help motivate survey participation. This article summarizes several theories underlying the use of incentives and briefly reviews research demonstrating their intended and unintended effects on response rates, sample composition, response bias, and response quality. It also considers the evidence for the effectiveness of incentives in reducing nonresponse bias. Institutional review boards have begun to ask whether, and under what conditions, the use of monetary incentives to induce participation might be coercive and to question the use of such incentives in surveys of "vulnerable" populations, including surveys of injury and violence. The article reviews the ethical principles underlying the requirement for voluntary informed consent as well as current regulations and a broad theoretical and empirical literature bearing on this question, concluding that incentives are never coercive. The question of whether they exert "undue influence" in a specific situation is more difficult, but it may be the wrong question to ask. The article concludes with several recommendations designed to ensure the ethical use of incentives in surveys on violence and injury.  相似文献

Dietary guidelines often deal with 100% fruit juice (FJ) inconsistently because it represents a source of free sugars. However, FJ also provides bioavailable micronutrients and plant bioactives at levels similar to those found in whole fruits. The present review weighs up the evidence from high-quality studies investigating a potential health harm for FJ against evidence from studies which indicate a potential health benefit. The findings reveal that FJ consumption, at moderate intakes consistent with the dietary guidelines for the US and some European countries (75–224 mL daily), does not increase the risk of obesity, type 2 diabetes, cardiovascular disease or poor glycaemic control. In contrast, regular consumption of FJ—even up to 500 mL per day in short-to-medium-term studies—appears to confer a health benefit in terms of vascular function and reduced blood pressure. Emerging evidence for cognitive health benefits requires further investigation in human trials. Observational studies report associations between FJ and nutrient adequacy and suggest that FJ consumption is associated with reduced risk of stroke. In conclusion, FJ appears to offer more benefit than risk and there appears to be no justification for discouraging FJ within a balanced diet for children and adults.  相似文献

Although age at first sex is considered a measure of sexual risk and vulnerability for HIV infection, there is a dearth of literature on age at sexual debut in the Canadian context. This study examined time variations to first sex among heterosexual African, Caribbean, and Black (ACB) men in four Ontarian cities. A population-based retrospective survey (n?=?879) on timing to first sexual intercourse was conducted between 2018 and 2019 among self-identified heterosexual ACB men 16 years or older and residing in London, Ottawa, Toronto or Windsor. We used the lognormal survival analysis technique to examine variations in time to first sexual intercourse among age cohorts and between cities. The findings showed a generational shift in the pattern of sexual initiation, with younger heterosexual ACB men initiating sexual intercourse earlier compared with those currently older than 50 years. We observed those between 16 and 19 years, 20 and 29 years, and 30 and 39 years of age to have significantly higher risk ratios of TR?=?0.852, TR?=?0.869, and TR?=?0.855, respectively. At city level, the results show marked spatial variations, with youth in cities of Toronto, Ottawa, and London at the highest risk of early sexual debut relative to those in Windsor. Early initiation of first sexual intercourse among heterosexual ACB youth was observed with those in the larger cities being at a relatively higher risk. There is the need for programs aimed at delaying sexual debut among youth in general. It is, however, important to recognize the relative risk of those in the larger cities.

Few HIV prevention interventions have been developed for African American men who have sex with men or who have sex with both men and women. Many interventions neglect the historical, structural or institutional, and sociocultural factors that hinder or support risk reduction in this high-risk group.We examined ways to incorporate these factors into Men of African American Legacy Empowering Self, a culturally congruent HIV intervention targeting African American men who have sex with men and women.We also studied how to apply key elements from successful interventions to future efforts. These elements include having gender specificity, a target population, a theoretical foundation, cultural and historical congruence, skill-building components, and well-defined goals.AFRICAN AMERICAN MEN WHO have sex with men (MSM) or who have sex with both men and women (MSMW) have the highest HIV prevalence among African Americans and among other racial/ethnic groups of MSM.13 However, HIV risk behaviors alone do not explain the disproportionate HIV rates among African American MSM.4,5 Attention to the sociocultural challenges facing African American MSM is needed.Only 1 published HIV behavioral intervention targets African American MSM6; none specifically target African American MSMW. Inclusion of culture is believed to improve the ability of public health programs to meet members'' needs.79 However, inherent abstractness and a lack of operationalized definitions and cultural competency pose challenges for those designing and implementing interventions.1014 Understanding the experiences of African American MSM requires attention to definitions of what it means to be African American and of male sexuality that are rooted in African American history and culture. Choices regarding identification with gay or bisexual labels and disclosure of Black same-gender sexual activities must be contextualized within African American communities.1517Health improvement among African American MSM requires attention to racism; gender role expectations; connection to partners, families, and communities; and HIV-related stigma.1822 Double minority status is made worse by high HIV rates and perceived responsibility for spreading HIV.2325 Even if family and community provide social support, homophobia and racism can deter African American MSM from disclosing their sexuality and seeking HIV prevention and care.26 Interventions must engage protective factors and address structural or institutional and sociocultural barriers to prevention.  相似文献
