A case-control study was conducted to investigate the association between the consumption of local common foods that are rich in vitamin A and the risk of lung cancer in Taiwan. A total of 301 incident lung cancer cases, 602 hospital controls, and 602 neighborhood controls were recruited. The consumption of 13 food items and vitamin supplements was estimated by use of a food frequency questionnaire. The conditional logistic regression models were used to estimate the adjusted odds ratios (AOR) and 95% confidence intervals (CI) for lung cancer risk with each control group as reference by adjustment of covariates. A reduced risk for lung cancer was found to be associated with increased intakes of vitamin A, alpha-carotene, and beta-carotene from 13 food items. More servings of vegetables (AOR for the highest versus the lowest quartile = 0.67-0.70, 95% CI = 0.42-1.08, (plinear trend )= 0.04), garland chrysanthemum (AOR for the highest versus the lowest tertile = 0.58-0.74, 95% CI = 0.37-1.14, (plinear trend )<= 0.04) and sweet potato leaves (AOR for the highest versus the lowest tertile = 0.43-0.65, 95% CI = 0.28-0.96, (plinear trend )<= 0.03) were associated with the reduced risk for lung cancer. In conclusion, higher consumption of vitamin A-rich vegetables, especially garland chrysanthemum and sweet potato leaves might provide potential protection from lung cancer. 相似文献

IntroductionMany factors contribute to sleep disturbance among young adults. Social media (SM) use is increasing rapidly, and little is known regarding its association with sleep disturbance.MethodsIn 2014 we assessed a nationally representative sample of 1788 U.S. young adults ages 19–32. SM volume and frequency were assessed by self-reported minutes per day spent on SM (volume) and visits per week (frequency) using items adapted from the Pew Internet Research Questionnaire. We assessed sleep disturbance using the brief Patient-Reported Outcomes Measurement Information System (PROMIS®) sleep disturbance measure. Analyses performed in Pittsburgh utilized chi-square tests and ordered logistic regression using sample weights in order to estimate effects for the total U.S. population.ResultsIn models that adjusted for all sociodemographic covariates, participants with higher SM use volume and frequency had significantly greater odds of having sleep disturbance. For example, compared with those in the lowest quartile of SM use per day, those in the highest quartile had an AOR of 1.95 (95% CI = 1.37–2.79) for sleep disturbance. Similarly, compared with those in the lowest quartile of SM use frequency per week, those in the highest quartile had an AOR of 2.92 (95% CI = 1.97–4.32) for sleep disturbance. All associations demonstrated a significant linear trend.DiscussionThe strong association between SM use and sleep disturbance has important clinical implications for the health and well-being of young adults. Future work should aim to assess directionality and to better understand the influence of contextual factors associated with SM use. 相似文献

Deported injection drug users (IDUs) in Mexico may be vulnerable to HIV infection following expulsion from the USA. We examined factors associated with HIV risk perception among a sample of deportees in Tijuana. From January to April 2010, 313 male IDUs who reported ever being deported from the USA completed a questionnaire. Overall, 35% (N = 110) of deportees perceived HIV risk. In multivariate logistic regression analyses, factors independently associated with HIV risk perception included ever having a steady female partner in Tijuana post-deportation (adjusted odds ratio [AOR]: 2.26; 95% confidence interval [CI]: 1.01–5.07) and years spent in a US prison (AOR: 1.29 per year; 95% CI: 1.13–1.48). Conversely, years of drug injection use (AOR: 0.95 per year; 95% CI: 0.91–0.99), ever witnessing family members use drugs prior to first migration trip (AOR: 0.24; 95% CI: 0.09–0.65), years of residence in the USA (AOR: 0.91 per year; 95% CI: 0.84–0.98) and being a Tijuana native (AOR: 0.40; 95% CI: 0.16–0.99) were negatively associated with HIV risk perception. US–Mexico border cities that receive deported migrants should target HIV prevention interventions to specific subgroups, including drug-using male deportees. Interventions should consider migrant's time in the USA, the role of their social networks, and reducing missed opportunities for HIV testing/education. 相似文献

BACKGROUND: Chinese injection drug users (IDUs) may be a proper candidate population for HIV vaccine trials. OBJECTIVE: To evaluate willingness to participate (WTP) in HIV vaccine trials among Chinese IDUs. METHODS: Questionnaire interviews were completed among 401 IDUs in Urumqi City in northwestern China in 2005. RESULTS: Overall 74.3% of participants said that they would be definitely willing to participate in HIV vaccine trials, 17.7% were probably willing, 6.2% were probably not willing, and remaining 1.8% were definitely not willing to join. Multivariate logistic regression analysis demonstrated that WTP was positively associated with having ever had sex with a drug use partner (adjusted odds ratio [AOR]: 1.8; 95% confidence interval [CI]: 1.04, 3.2), sharing needle and syringe with a new drug use partner in the past 3 months (AOR: 3.8; 95% CI: 1.2, 11.7), perceived family support for participation (AOR: 7.4; 95% CI: 4.3, 12.7), and perceived vaccine protection against HIV infection (AOR: 16.1; 95% CI: 3.7, 70.8), and was negatively associated with perceived risk of social stigma and isolation for participation (AOR: 0.3; 95% CI: 0.2, 0.5). CONCLUSIONS: The stated WTP in hypothetical HIV vaccine trials was high among Chinese IDUs. Further studies are needed to evaluate actual enrollment into the trials. 相似文献

Numerous studies have investigated the deleterious effects of maternal depression on child outcomes. Knowledge of characteristics of these mothers is incomplete, as most studies utilize small samples or limit investigation to the postpartum period. Utilizing data from a nationally representative sample of 7,211 fathers and mothers living in households with children aged 5–17 years who participated in the Medical Expenditure Panel Survey (MEPS) 2004–2006, the Patient Health Questionnaire-2 (PHQ-2) was used to assess parental depressive symptoms, the Short Form-12 (SF-12) was used to examine paternal and maternal physical health, and the Columbia Impairment Scale was used to measure child behavioral or emotional problems. In multivariate analyses, maternal unemployment (AOR 1.76, 95 % CI 1.31–2.35); living with smokers (AOR 1.82, 95 % CI 1.12–2.94); poor maternal physical health (AOR 2.31; 95 % CI 1.81–2.94); living with children with behavioral or emotional problems (AOR 2.95, 95 % CI 2.30–3.96); and paternal depressive symptoms (AOR 5.11, 95 % CI 1.97–13.25) each were independently associated with increased rates of maternal depressive symptoms. This paper is the first we are aware of to use a nationally representative sample to investigate characteristics associated with maternal depressive symptoms and found that maternal unemployment, living with smokers, poor maternal physical health, having children with behavioral or emotional problems, and paternal depressive symptoms are each independently associated with maternal depressive symptoms. In these data, paternal depressive symptoms are associated with the greatest risk of mothers exhibiting depressive symptoms, a finding that we believe has never before been shown. 相似文献

Depression is more common among drug users (15–63 %) than the general population (5–16 %). Lack of social support network members may be associated with low mental health service (MHS) use rates observed among drug users. We investigated the relationship between social network members’ roles and MHS use among frequent drug users using Social Ties Associated with Risk of Transition into Injection Drug Use data (NYC 2006–2009). Surveys assessed depression, MHS use, demographics, drug use and treatment, and social network members’ roles. Participants reporting lifetime depressive episode with start/end dates and information on social/risk network members were included (n = 152). Adjusting for emotional support and HIV status, having one or more informational support network members remained associated with MHS use at last depressive episode (adjusted odds ratio (AOR) 3.37, 95 % confidence interval (CI) 1.38–8.19), as did history of drug treatment (AOR 2.75, 95 % CI 1.02–7.41) and no legal income (AOR 0.23, 95 % CI 0.08–0.64). These data suggest that informational support is associated with MHS utilization among depressed drug users. 相似文献

Despite extensive documentation of the reentry challenges facing female prisoners, few such studies have focused on women exiting jails. The Window Study investigated factors associated with the perceived availability of stable housing upon release from detention. Anonymous surveys were conducted with a random sample (n=148) of female detainees at the Baltimore City Detention Center from January 21 to March 17, 2005. Interviews focused on socio-demographic background, health status, recent drug use and sexual behavior history, and material and social resource availability upon release. The median age of female detainees was 37 (interquartile range [IQR]: 29, 41), 69% were African-American, and 33% identified as lesbian or bisexual. The median income in the 30 days prior to arrest was $145 (IQR: 0, 559), and the median number of prior arrests was 5 (IQR: 3, 11). In the presence of other variables familial support (Adjusted Odds Ratio [AOR] 2.57; 95% Confidence Interval [CI] 1.21, 5.47) and a monthly income of $400-799 (AOR 3.18; 95% CI 1.00, 10.07) were positively associated with perceived housing stability upon release; wanting a support group for having traded sex for money, drugs or a place to stay (AOR 0.25; 95% CI 0.10, 0.63) was significantly negatively associated with perceived housing stability upon release. This study suggests the importance of pre-release planning and continuity of care for female detainees. Interventions should emphasize access to housing, economic opportunity and family reunification. Special attention is warranted to those who have engaged in sex work, who may be marginalized from family and service-based support networks. 相似文献

BACKGROUND: The effectiveness of mammography screening could be improved if factors that influence nonattendance were better understood. METHODS: We examined attitudes, beliefs, and knowledge in relation to nonattendance in a population-based mammography screening program, using a case-control design. Data were collected from November 1997 to March 1998 through telephone interviews with 434 nonattenders and 515 attenders identified in a population-based mammography register in central Sweden. The questions asked drew primarily upon the components constituting the Health Belief Model. RESULTS: Multivariate analysis showed that nonattendance was most common among women within the highest quartile of perceived emotional barriers, compared to women within the lowest quartile (OR = 4.81; 95% CI 2.96-7.82). Women who worried most about breast cancer were more likely to attend than those who worried least (OR = 0.09; 95% CI 0.02-0.31). Women with the highest scores of perceived benefits were more likely to attend than women with the lowest ones (OR = 0.35; 95% CI 0.08-0.75). Other factors associated with nonattendance were less knowledge about mammography and breast cancer, lack of advice from a health professional to participate, and very poor trust in health care. CONCLUSIONS: Our findings suggest that increased participation in outreach mammography screening programs can be achieved through enhancement of breast cancer awareness and possibly by reducing some of the modifiable barriers. mammography; mass screening; breast cancer; attitudes; Sweden. 相似文献

BACKGROUND: Demographic and psychosocial correlates of activity in domains other than recreational activity have not been well characterized and may be particularly relevant for health promotion efforts aimed at women. METHODS: Cross-sectional relationships between recreational, occupational, and household/caregiving physical activity and demographic and psychosocial factors were assessed with a mail survey in a random sample of 2,636 ethnically diverse women members of a large health maintenance organization, ages 20-65. Activity was assessed with a modified Baecke questionnaire that uses categorical responses regarding frequency of domain-specific activities to create four semicontinuous activity indices (sports/exercise, active living, occupational, household/caregiving). RESULTS: Multivariable logistic regression analysis showed that the likelihood of being in the highest quartile of the sports/exercise and active-living indices, compared with the other three quartiles, was decreased among older, nonwhite, less well educated, heavier women who had young children at home, lacked motivation to exercise, and perceived external obstacles to exercise behavior. The odds ratios (ORs) ranged from 0.38, 95% confidence interval (CI) 0.33-0.45, associated with low motivation, to 0.95, 95% CI 0.93-0.98, associated with increasing body mass index. Social support and confidence in one's ability to continue to exercise, even when faced with other pressures and demands (termed self-efficacy), were associated with increased likelihood of high levels of sports/exercise and active living (OR = 2.34, 95% CI 1. 83-2.98 and OR = 3.96, 95% CI 2.92-5.38, respectively). In contrast, the highest quartile of household/caregiving activity was positively associated with increasing age (OR = 1.28, 95% CI 1.16-1.42), Hispanic ethnicity (OR = 1.58, 95% CI 0.55-1.01), being married (OR = 1.70, 95% CI 1.33-2.18), having young children at home (OR = 6.99, 95% CI 4.33-11), and greater time constraints as a barrier to exercise (OR = 1.55, 95% CI 1.38-1.74) and was negatively associated with employment (OR = 0.38, 95% CI 0.30-0.47). Increased likelihood of the highest quartile of occupational activity was associated with high school education or less (OR = 2.26, 95% CI 1.74-2.94) and current smoking (OR = 1.66, 95% CI 1.23-2.23), while self-efficacy regarding exercise was associated with decreased likelihood (OR = 0. 77, 95% CI 0.61-0.96). CONCLUSIONS: These findings suggest that demographic and psychosocial correlates of physical activity vary by domain and that initiatives to promote physical activity in the population need to take these differences into account. 相似文献

Extensive research shows maternal depression to be associated with poorer child outcomes, and characteristics of these mothers have been described. Recent research describes associations of paternal depressive symptoms and child behavioral and emotional outcomes, but characteristics of these fathers have not been investigated. This study describes characteristics of fathers with depressive symptoms in the USA. Utilizing data from 7,247 fathers and mothers living in households with children aged 5–17 years who participated in the Medical Expenditure Panel Survey 2004–2006, the Patient Health Questionnaire-2 was used to assess parental depressive symptoms, the Short Form-12 was used to examine paternal and maternal physical health, the Columbia Impairment Scale was used to measure child behavioral or emotional problems, and the Children with Special Health Care Needs Screener was used to identify children with special health care needs. In multivariate analyses, poverty (AOR 1.52; 95% CI 1.05–2.22), maternal depressive symptoms (AOR 5.77; 95% CI 4.18–7.95), living with a child with special health care needs (AOR 1.42, 95% CI 1.04–1.94), poor paternal physical health (AOR 3.31; 95% CI 2.50–4.38) and paternal unemployment (AOR 6.49; 95% CI 4.12–10.22) were independently associated with increased rates of paternal depressive symptoms. These are the first data that demonstrate that poverty, paternal physical health problems, having a child with special health care needs, maternal depressive symptoms, and paternal unemployment are independently associated with paternal depressive symptoms, with paternal unemployment associated with the highest rates of such problems. 相似文献

Individuals who use illicit drugs and belong to a sexual minority group often contend with elevated risks for adverse health outcomes. However, little is known about women who use drugs and have sex with women. We therefore sought to identify sociodemographic, substance use patterns, and exposures to social-structural factors associated with reporting sexual activity among women participating in three open prospective cohort studies of individuals who use illicit drugs in Vancouver, Canada. Generalized estimating equations were used to identify substance use patterns, violence, and other social and structural drivers of health-related harm among women who reported having sex with women (WSW) between December 2005 and May 2012. In multivariate analyses, younger age (adjusted odds ratio [AOR] 2.89; 95 % confidence interval [CI] 1.81, 4.60), violence (AOR 1.78; 95 % CI 1.22, 2.59), and homelessness (AOR 1.42; 95 % CI 1.00, 2.02) were associated with WSW. WSW were also less likely to report enrollment in addiction treatment (AOR 0.68; 95 % CI 0.46, 0.99). In a second model, sexual violence (AOR 3.47; 95 % CI 2.08, 5.78) in the previous 6 months was also found to be positively associated with WSW. These findings indicate a critical need for more thorough understandings of the intersections between sexual relationships, exposure to violence, and enrollment in addiction treatment among women who use illicit drugs, as well as the development of programs to address the unique needs of this population. 相似文献

BackgroundCalifornia may vote on marijuana legalization in 2016. Young adults have the highest rates of marijuana use, but little is known about the correlates of use in this age group, including factors that may be affected by policy change. We investigated whether there are differences in marijuana use by sociodemographic characteristics, psychological distress, loneliness and social support, controlling for risk factors such as alcohol and cigarette use as well as perceived harm of marijuana.MethodsBivariate and multivariable analysis of past 30 day marijuana use using the 2014 San Francisco Bay Area Young Adult Health Survey, a probabilistic multi-mode survey of (N = 1324) young adults (aged 18–26 years) residing in Alameda and San Francisco Counties, stratified by race/ethnicity.Results291 (27%) sample participants reported current marijuana use. Compared to non-Hispanic Whites (referent) Asian/Pacific Islander respondents were less likely to use marijuana (AOR, 0.42; 95% CI, 0.22–0.80) while multiracial participants were twice as likely (AOR, 2.27; 95% CI, 1.06–4.85). Psychological distress was not related to marijuana use, but social support (AOR, 1.42; 95% CI, 1.08–1.88) and loneliness (AOR, 1.42; 95% CI, 1.09–1.86) were. Perceived harm of marijuana was inversely related to marijuana use (AOR, 0.60; 95% CI, 0.51–0.70), while smoking cigarettes (AOR, 3.95; 95% CI, 2.28–6.84) and binge drinking (AOR, 1.13; 95% CI, 1.03–1.24) were positively related.ConclusionsLegalization policies should include public education campaigns addressing potential harms of marijuana use particularly targeting multiracial young adults who also engage in other risk behaviors, such as cigarette smoking and binge drinking. 相似文献

Because little is known about the etiology of non-Hodgkin lymphoma (NHL), a heterogeneous disease, and because dietary factors are modifiable, the authors examined the associations between nutrients related to one-carbon metabolism and risk of NHL in a population-based case-control study of Connecticut women diagnosed between 1996 and 2000. A total of 594 cases and 710 controls completed a food frequency questionnaire for determination of intakes of folate, vitamins B(2), B(6), and B(12), and methionine. Through unconditional logistic regression, the authors estimated the risk of NHL associated with intake of each nutrient. Comparing the highest quartile of intake with the lowest, the authors found lower risks of all NHL associated with increasing intakes of folate and methionine. Analysis by NHL subtype indicated lower risks of diffuse large B-cell lymphoma (highest quartile vs. lowest: odds ratio (OR) = 0.54, 95% confidence interval (CI): 0.30, 0.98; p-trend = 0.02) and marginal zone lymphoma (highest quartile vs. lowest: OR = 0.08, 95% CI: 0.02, 0.26; p-trend < 0.0001) associated with folate. Vitamin B(6) intake was also associated with lower risk of NHL overall and of marginal zone lymphoma (highest quartile vs. lowest: OR = 0.23, 95% CI: 0.08, 0.65; p-trend = 0.002). These findings suggest that these nutrients may be important for susceptibility to NHL. 相似文献

Social networks are increasingly recognized as important determinants of many chronic diseases, yet little data exist regarding
the influence of social networks on diabetes. We surveyed diabetic patients to determine how social networks affect their
overall level of concern regarding diabetes and its complications. We adapted a previously published instrument and surveyed
240 diabetic patients at two primary care practices. Patients recorded the number of family and friends who had diabetes and
rated their level of concern about diabetes on a scale of 0% (no concern) to 100% (extremely concerned). Our primary outcome
variable was patients’ level of concern (<75% or ≥75%). We developed logistic regression models to determine the effect of
disease burden in patients’ social networks on expressed level of concern about diabetes. We received 154 surveys (64% response
rate). We found that for each additional family member with diabetes, patients expressed a greater level of concern about
diabetes (AOR 1.5; 95% CI 1.2–2.0) and its potential complications (AOR 1.4; 95% CI 1.1–1.7). Similarly, patients with an
increased number of friends with diabetes expressed greater concern about diabetes (AOR 1.5; 95% CI 1.2–1.9) and its complications
(AOR 1.3; 95% CI 1.1–1.7). Patients with a higher prevalence of diabetes within their social networks expressed greater concern
about diabetes and diabetic complications. Determining disease burden within patients’ social networks may allow physicians
to better understand patients’ perspectives on their disease and ultimately help them achieve meaningful behavioral change. 相似文献

Limited research has examined the social context surrounding stigma and discrimination and HIV outcomes among people living with HIV (PLHIV). We surveyed 900 PLHIV in Brazil and examined the relationship between stigma, discrimination and HIV outcomes utilising multivariable logistic regression. HIV stigma and discrimination were inversely associated with age (AOR Stigma 0.65, 95% CI 0.49–0.88; AOR Discrimination 0.72, 95% CI 0.54–0.95) and income (AOR Stigma 0.74, 95% CI 0.55–0.99; AOR Discrimination 0.62, 95% CI 0.46–0.82). Stigma was inversely associated with education (AOR 0.71, 95% CI 0.52–0.96) and no history of sex work (AOR 0.56, 95% CI 0.35–0.90), and positively associated with having children (AOR 1.71, 95% CI 1.18–2.48). Discrimination was inversely associated with no history of drug use (AOR 0.63, 95% CI 0.42–0.95). Stigma and discrimination were found to be inversely associated with overall health (AOR Stigma 0.54, 95% CI 0.40–0.74; AOR Discrimination 0.71, 95% CI 0.52–0.97). Discrimination was associated with having a sexually transmitted infection since HIV diagnosis (AOR 1.63, 95% CI 1.14–2.32). Findings suggest that future interventions should address multiple social inequalities faced by PLHIV to reduce HIV stigma and discrimination and improve health and HIV outcomes. 相似文献

The aim of the Belstress Study was to see whether use of benzodiazepines is associated with perceived job stress as measured by Karasek's job-strain model. This model has as its central tenet that the most adverse health outcomes are to be expected in high strain jobs characterized by high job demands and low job control. An extension of the model states that the most noxious combination is high job demands, low control and low social support at work. Sample subjects were recruited from 25 Belgian companies between 1994 and 1998, and cover a wide range of occupations. A 5.6% of 16,094 men and 9.3% of 5012 women aged 35-59 years report use of benzodiazepines during the last month. A clear association is displayed between self-reported use of benzodiazepines and a high strain job compared to a low strain job (men: OR=1.93, 99% CI=1.4-2.6; women: OR=1.66, 99% CI=1.0-2.7), after adjustment is made for socio-demographic confounders (age, level of education, occupational group, employment sector, living situation). The independent association with quartile level of job demands is a striking feature (men: OR of highest quartile compared to lowest quartile group=1.91, 99% CI=1.4-2.6; women: OR=1.99, 99% CI=1.3-3.1). In men, an inverse association with quartile level of job control is observed (OR= 0.65, 99% CI=0.5-0.9) whereas in women a clear tendency in that direction is displayed (OR=0.62, 99% CI=0.4-1.1). The association with low social support is less clear; an independent association between use of benzodiazepines and iso-strain was observed particularly in men. 相似文献

The purpose of the study was to determine the potential contribution of bisexual men to the spread of HIV in Los Angeles. We compare the characteristics and behaviors of men who have sex with men and women (MSMW) to men who have sex with only women (MSW) and men who have sex with only men (MSM) in Los Angeles. Men (N?=?1,125) who participated in one of the two waves of data collection from 2005 to 2007 at the Los Angeles site for NIDA’s Sexual Acquisition and Transmission of HIV—Cooperative Agreement Program were recruited using Respondent Driven Sampling. Participants completed Audio Computer Assisted Self Interviews and received oral HIV rapid testing with confirmatory blood test by Western Blot and provided urine specimens for detection of recent powder cocaine, crack cocaine, methamphetamine, or heroin use. MSM, MSW, or MSMW were defined by the gender of whom they reported sex with in the past 6 months. Chi-square tests and ANOVAs were used to test independence between these groups and demographic characteristics, substance use, and sexual behaviors. We fit generalized linear random intercept models to predict sexual risk behaviors at the partner level. Men were mostly of low income, unemployed, and minority, with many being homeless; 66% had been to jail or prison, 29% had ever injected drugs, and 25% had used methamphetamine in the past 30 days. The sample had high HIV prevalence: 12% of MSMW, 65% of MSM, and 4% of MSW. MSMW were behaviorally between MSW and MSM, except that more MSMW practiced sex for trade (both receiving and giving), and more MSMW had partners who are drug users than MSW. Generalized linear random intercept models included a partner-level predictor with four partner groups: MSM, MSMW-male partners, MSMW-female partners, and MSW. The following were significantly associated with unprotected anal intercourse (UAI): MSW (AOR 0.15, 95% CI 0.08, 0.27), MSMW-female partners (AOR 0.4, 95% CI 0.27, 0.61), HIV-positive partners (AOR 2.03, 95% CI 1.31, 3.13), and being homeless (AOR 1.37, 95% CI 1.01, 1.86). The factors associated with giving money or drugs for sex were MSMW-female partners (AOR 1.70, 95% CI 1.09, 2.65), unknown HIV status partners (AOR 1.72, 95% CI 1.29, 2.30), being older (AOR 1.02, 95% CI 1.00, 1.04), history of incarceration (AOR 1.64, 95% CI 1.17, 2.29), and being homeless (AOR 1.73, 95% CI 1.27, 2.36). The following were associated with receiving money or drugs for sex: MSW (AOR 0.53, 95% CI 0.32, 0.89), African American (AOR 2.42, 95% CI 1.56, 3.76), Hispanic (AOR 1.85, 95% CI 1.12, 3.05), history of incarceration (AOR 1.44, 95% CI 1.04, 2.01), history of injecting drugs (AOR 1.57, 95% CI 1.13, 2.19), and had been recently homeless (AOR 2.14, 95% CI 1.57, 2.94). While overall HIV-positive MSM had more UAI with partners of any HIV status than MSMW with either partner gender, among HIV-positive MSMW, more had UAI with HIV-negative and HIV status unknown female partners than male partners. Findings highlight the interconnectedness of sexual and drug networks in this sample of men—as most have partners who use drugs and they use drugs themselves. We find a concentration of risk that occurs particularly among impoverished minorities—where many men use drugs, trade sex, and have sex with either gender. Findings also suggest an embedded core group of drug-using MSMW who may not so much contribute to spreading the HIV epidemic to the general population, but driven by their pressing need for drugs and money, concentrate the epidemic among men and women like themselves who have few resources. 相似文献
