Gender-specific Correlates of Sex Trade among Homeless and Marginally Housed Individuals in San Francisco

Objective: Sex exchange is a well-established risk factor for HIV infection. Little is known about how correlates of sex trade differ by biologic sex and whether length of homelessness is associated with sex trade. We conducted a cross-sectional study among a sample of 1,148 homeless and marginally housed individuals in San Francisco to assess correlates of exchanging sex for money or drugs. Key independent variables included length of homelessness; use of crack, heroin or methamphetamine; HIV status; and sexual orientation. Analyses were restricted by biologic sex. In total, 39% of women and 30% of men reported a lifetime history of sex exchange. Methamphetamine use and greater length of homelessness were positively associated with a history of sex trade among women, while heroin use, recent mental health treatment, and homosexual or bisexual orientation were significantly associated with sex trade for men. Crack use was correlated with sex trade for both genders. Correlates of sex trade differ significantly according to biologic sex, and these differences should be considered in the design of effective HIV prevention programs. Our findings highlight the critical need to develop long-term services to improve housing status for homeless women, mental health services for homeless men, and drug treatment services for homeless adults involved in sex work.Weiser, Dilworth, and Neilands are with the Center for AIDS Prevention Studies, University of California, San Francisco (UCSF), San Francisco, CA, USA.

Sexual Networks and Housing Stability

Unstable housing is related to a range of health problems including substance abuse, poor mental health, and HIV. Little is known about how sexual partners’ attributes influence access to resources such as housing. The purpose of the present study was to examine the relationship between sexual network characteristics and improvements in housing situation among a sample of drug users using a longitudinal design. Size of one’s sex network was not associated with housing change. However, having a main partner and having a sex partner who lent money was associated with moving from a homeless state at baseline to being housed at follow-up. Also, having a sex partner who was a drug user was associated with decrease in the odds of improving one’s housing situation.     

Housing Status,Medical Care,and Health Outcomes Among People Living With HIV/AIDS: A Systematic Review

Background. Accumulating evidence suggests responses to HIV that combine individual-level interventions with those that address structural or contextual factors that influence risks and health outcomes of infection. Housing is such a factor. Housing occupies a strategic position as an intermediate structural factor, linking “upstream” economic, social, and cultural determinants to the more immediate physical and social environments in which everyday life is lived. The importance of housing status for HIV prevention and care has been recognized, but much of this attention has focused on homeless individuals as a special risk group. Analyses have less often addressed community housing availability and conditions as factors influencing population health or unstable, inadequate, or unaffordable housing as a situation or temporary state. A focus on individual-level characteristics associated with literal homelessness glosses over social, economic, and policy drivers operating largely outside any specific individual’s control that affect housing and residential environments and the health resources or risk exposures such contexts provide.Objectives. We examined the available empirical evidence on the association between housing status (broadly defined), medical care, and health outcomes among people with HIV and analyzed results to inform future research, program development, and policy implementation.Search methods. We searched 8 electronic health and social science databases from January 1, 1996, through March 31, 2014, using search terms related to housing, dwelling, and living arrangements and HIV and AIDS. We contacted experts for additional literature.Selection criteria. We selected articles if they were quantitative analyses published in English, French, or Spanish that included at least 1 measure of housing status as an independent variable and at least 1 health status, health care, treatment adherence, or risk behavior outcome among people with HIV in high-income countries. We defined housing status to include consideration of material or social dimensions of housing adequacy, stability, and security of tenure.Data collection and analysis. Two independent reviewers performed data extraction and quality appraisal. We used the Cochrane Risk of Bias Tool for randomized controlled trials and a modified version of the Newcastle Ottawa Quality Appraisal Tool for nonintervention studies. In our quality appraisal, we focused on issues of quality for observational studies: appropriate methods for determining exposure and measuring outcomes and methods to control confounding.Results. Searches yielded 5528 references from which we included 152 studies, representing 139 757 HIV-positive participants. Most studies were conducted in the United States and Canada. Studies examined access and utilization of HIV medical care, adherence to antiretroviral medications, HIV clinical outcomes, other health outcomes, emergency department and inpatient utilization, and sex and drug risk behaviors. With rare exceptions, across studies in all domains, worse housing status was independently associated with worse outcomes, controlling for a range of individual patient and care system characteristics.Conclusions. Lack of stable, secure, adequate housing is a significant barrier to consistent and appropriate HIV medical care, access and adherence to antiretroviral medications, sustained viral suppression, and risk of forward transmission. Studies that examined the history of homelessness or problematic housing years before outcome assessment were least likely to find negative outcomes, homelessness being a potentially modifiable contextual factor. Randomized controlled trials and observational studies indicate an independent effect of housing assistance on improved outcomes for formerly homeless or inadequately housed people with HIV. Housing challenges result from complex interactions between individual vulnerabilities and broader economic, political, and legal structural determinants of health. The broad structural processes sustaining social exclusion and inequality seem beyond the immediate reach of HIV interventions, but changing housing and residential environments is both possible and promising.     

Emergency department use among the homeless and marginally housed: results from a community-based study

OBJECTIVES: This study examined factors associated with emergency department use among homeless and marginally housed persons. METHODS: Interviews were conducted with 2578 homeless and marginally housed persons, and factors associated with different patterns of emergency department use were assessed in multivariate models. RESULTS: Findings showed that 40.4% of respondents had 1 or more emergency department encounters in the previous year; 7.9% exhibited high rates of use (more than 3 visits) and accounted for 54.5% of all visits. Factors associated with high use rates included less stable housing, victimization, arrests, physical and mental illness, and substance abuse. Predisposing and need factors appeared to drive emergency department use. CONCLUSIONS: Efforts to reduce emergency department use among the homeless should be targeted toward addressing underlying risk factors among those exhibiting high rates of use.     

Housing Instability and Incident Hypertension in the CARDIA Cohort

Housing instability, a growing public health problem, may be an independent environmental risk factor for hypertension, but limited prospective data exist. We sought to determine the independent association of housing instability in early adulthood (year 5, 1990–1991) and incident hypertension over the subsequent 15 years of follow-up (years 7, 10, 15, and 20) in the Coronary Artery Risk Development in Young Adults (CARDIA) study (N = 5,115). Because causes of inadequate housing and its effects on health are thought to vary by race and sex, we hypothesized that housing instability would exert a differential effect on incident hypertension by race and sex. At year 5, all CARDIA participants were asked about housing and those free of hypertension were analyzed (N = 4,342). We defined housing instability as living in overcrowded housing, moving frequently, or living doubled up. Of the 4,342 participants, 8.5 % were living in unstable housing. Across all participants, housing instability was not associated with incident hypertension (incidence rate ratio (IRR), 1.1; 95 % CI, 0.9–1.5) after adjusting for demographics, socioeconomic status, substance use, social factors, body mass index, and study site. However, the association varied by race and sex (p value for interaction, <0.001). Unstably housed white women had a hypertension incidence rate 4.7 times (IRR, 4.7; 95 % CI, 2.4–9.2) that of stably housed white women in adjusted analysis. There was no association among white men, black women, or black men. These findings suggest that housing instability may be a more important risk factor among white women, and may act independently or as a marker for other psychosocial stressors (e.g., stress from intimate partner violence) leading to development of hypertension. Studies that examine the role of these psychosocial stressors in development of hypertension risk among unstably housed white women are needed.     

Homelessness and HIV risk behaviors among drug injectors in Puerto Rico

This report examines associations between homelessness and HIV risk behaviors among injection drug users (IDUs) in Puerto Rico. The study sample consisted of 557 IDUs who were not in treatment, recruited in inner-city neighborhoods of the North Metro Health Care Region. Subjects were categorized into three groups by residential status (last 30 days): housed, transitionally housed (living with friends, family, or others but considering themselves homeless), and on-the-street homeless (living on the street or in a shelter). Multiple logistic regression models were fitted to assess effects of residential status on each HIV risk behavior after adjusting for sociodemographic and drug-use related covariates. Transitionally housed and on-the-street homeless subjects made up 16% of the total sample. On-the-street homeless IDUs were more likely to test positive for HIV than were transitionally housed and housed IDUs. In the adjusted analysis, on-the-street homeless subjects were significantly more likely to share needles, share rinse water, and practice back loading than the other two groups. Sexual risk behaviors (last 30 days) were not significantly associated with residential status after adjustment. Findings from this study present an added challenge to drug treatment and HIV prevention and treatment programs, to provide services that can address the additional needs of drug users suffering the stressors of homelessness.     

Identifying homelessness at an urban public hospital: a moving target?

Hospitals do not routinely collect data about homelessness. The objectives of the present study were to (1) describe rate of patient reports of homelessness among inpatients at a public hospital, (2) assess the agreement between patient report of housing status on a study questionnaire with clinical and administrative data about homelessness, and (3) assess changes in housing status during hospitalization. We conducted a cross-sectional survey of inpatients at an urban public hospital to assess housing status; we then examined subjects' medical charts to assess agreement with the questionnaire on housing status. Of inpatients, 25.6% were homeless at discharge. An additional 19.4% were marginally housed. One third of homeless persons had their housing status change during their hospitalization. Administrative data identified 25.6% and physicians' notes identified 22.5% as homeless. Clinical, administrative, and survey data did not agree. Homelessness and changes in housing status are common among inpatients at an urban public hospital. Poor agreement on who is homeless limits the usefulness of data.     

The HIV Risk Reduction Needs of Homeless Women in Los Angeles

BackgroundSubstance use, housing instability, and transactional sex all contribute to HIV risk engagement among homeless women. Because of the increased risk of HIV among homeless women, this study sought to understand the context of sexual behaviors and condom use among homeless women and elucidate modifiable factors that can be targeted by interventions.MethodsHomeless women (n = 45) participated in focus groups (n = 6) at shelters throughout Los Angeles County. Thematic analyses revealed that similar to other high-risk women, homeless women engage in sex with multiple types of partners (steady, casual, and transactional).FindingsOur findings indicate that, similar to use among other high-risk women, condom use by homeless women varied by type of partner. Substance use also contributed to condom non-use. In a departure from previous research, homeless women reported overarching feelings of hopelessness. Participants spoke of hopelessness contributing to risk engagement, specifically the number of ongoing stressors experienced because of homelessness contributing to despair. Without acknowledgement of this unique quality of homelessness, women felt their risk reduction needs would never truly be understood.ConclusionsInterventions involving homeless women should include self-esteem building, acknowledgment and use of inherent resilience qualities gained during homelessness, respect for current knowledge and skills, and an exploration of when women choose to trust their partners and how they make safer sex choices.     

Access and utilization of HIV treatment and services among women sex workers in Vancouver’s downtown eastside

Many HIV-infected women are not realizing the benefits of highly active antiretroviral therapy (HAART) despite significant advancements in treatment. Women in Vancouver’s Downtown Eastside (DTES) are highly marginalized and struggle with multiple morbidities, unstable housing, addiction, survival sex, and elevated risk of sexual and drug-related harms, including HIV infection. Although recent studies have identified the heightened risk of HIV infection among women engaged in sex work and injection drug use, the uptake of HIV care among this population has received little attention. The objectives of this study are to evaluate the needs of women engaged in survival sex work and to assess utilization and acceptance of HAART. During November 2003, a baseline needs assessment was conducted among 159 women through a low-threshold drop-in centre servicing street-level sex workers in Vancouver. Cross-sectional data were used to describe the sociodemographic characteristics, drug use patterns, HIV/hepatitis C virus (HCV) testing and status, and attitudes towards HAART. High rates of cocaine injection, heroin injection, and smokeable crack cocaine use reflect the vulnerable and chaotic nature of this population. Although preliminary findings suggest an overall high uptake of health and social services, there was limited attention to HIV care with only 9% of the women on HAART. Self-reported barriers to accessing treatment were largely attributed to misinformation and misconceptions about treatment. Given the acceptability of accessing HAART through community interventions and women specific services, this study highlights the potential to reach this highly marginalized group and provides valuable baseline information on a population that has remained largely outside consistent HIV care.     

HIV Sexual Risk and Syndemics among Women in Three Urban Areas in the United States: Analysis from HVTN 906

Limited data are available on the longitudinal occurrence of syndemic factors among women at risk for HIV infection in the USA and how these factors relate to sexual risk over time. HVTN 906 was a longitudinal study enrolling 799 HIV-uninfected women in three cities. Assessments were done at baseline, 6, 12, and 18 months to assess syndemic factors (low education, low income, unemployment, lack of health insurance, housing instability, substance use, heavy alcohol use, partner violence, incarceration) and sexual risk outcomes. For each sexual risk outcome, a GEE model was fit with syndemic factors or syndemic score (defined as sum of binary syndemics, ranging from 0 to 9), visit, study site, age and race/ethnicity as predictors to examine the multivariable association between syndemic factors and outcomes over time. Odds of unprotected sex while drunk or high were significantly higher when women reported lack of health insurance, substance and heavy alcohol use and partner violence. Housing instability, substance and heavy alcohol use, partner violence and recent incarceration were associated with higher odds of having multiple sexual partners. Odds of sex exchange were significantly higher in the presence of unemployment, housing instability, low education, lack of health insurance, substance and heavy alcohol use, partner violence and incarceration. Housing instability, substance and heavy alcohol use, and partner violence were significantly associated with higher odds of unprotected anal sex. Odds of having a recent STI were significantly higher when women reported housing instability and partner violence. There were significantly higher odds of the reporting of any risk outcomes during follow-up with higher syndemic score. This study highlights a group of women experiencing multiple poor social and health outcomes who need to be the focus of comprehensive interventions.     

Are Parental Relationships Always Protective? A Social Network Analysis of Black,Latino, and White Homeless Youth and Sexual Risk-Taking Behaviors

Black and Latino homeless youth are at high risk of HIV, and yet no HIV prevention interventions have been specifically designed for these groups. Given the success of parent–child intervention programs for housed Black and Latino youth, this study examined parental relationships that could be leveraged for future HIV prevention efforts targeting minority homeless youth, specifically the associations among presence of parents in social networks, parental influence, and parental support. A convenience sample of Black, Latino, and White homeless youth (N?=?754) was recruited from three drop-in centers in Los Angeles. Participants completed a computerized, self-administered questionnaire and an interviewer-led personal social network interview. Multivariate logistic regression models assessed the association between parental relationships and sexual risk behaviors. Forty-five percent (n?=?338) of youth identified a parent in their network. Having at least one parent in their network was significantly associated with decreased odds of using a condom for Black and White youth. Black youth were almost four times more likely to report being tested for HIV if they spoke to their parents about sex, whereas Latino youth were 91 % less likely to report being tested for HIV if they talked with their parents about sex. Black youth who identified a parent as a positive influence (i.e., promoting condom use or discouraging multiple partners) were almost four times more likely to have used a condom during their last sexual encounter. Parent–child HIV prevention interventions targeting homeless youth would benefit from culturally tailored adaptations.     

Unstable housing, associated risk behaviour, and increased risk for HIV infection among injection drug users

We sought to examine the relationship between housing status and risk of HIV-infection among injection drug users in Vancouver, Canada. Using Kaplan-Meier survival analysis, we found an elevated HIV incidence rate among those who reported residing in unstable housing (log-rank p=0.006). In Cox's regression survival analysis, unstable housing remained marginally associated with elevated risks of HIV infection (relative hazard=1.40 (95% confidence interval: 0.09-2.00); p=0.084) after adjustment for potential confounders including syringe sharing. Adjusted generalized estimating equations analysis that examined factors associated with unstable housing demonstrated that residing in unstable housing was independently associated with several HIV risk behaviours including borrowing used needles (adjusted odds ratio (OR)=1.14) and sex-trade involvement (adjusted OR=1.19). Our findings suggest that unstable housing environments are associated with elevated risk of HIV- infection due to risk behaviours that take place in these environments. Implications for policy including more comprehensive housing interventions (e.g. 'floating support') are discussed.     

Sex Trade Behavior among Heterosexually Active Homeless Men

Sex trade behavior is fairly common among homeless adults and may contribute to higher rates of HIV/AIDS in this population. This study provides a detailed examination of the sex trade-related attitudes and behaviors of homeless men by: (1) determining the prevalence of sex trade-related behaviors, including sex with female sex workers (FSWs); (2) identifying risk factors for having sex with FSWs; and (3) comparing men’s relationships with FSWs and non-FSWs in terms of relationship qualities and HIV-related risk behaviors, such as condom use. Structured interviews were conducted with a probability sample of 305 heterosexually active homeless men recruited from meal lines in Los Angeles. Recent sex with a FSW was reported by 26 % of men, and more likely among those who were older, used crack cocaine, had more sex partners, believed that sometimes men just need to have sex no matter what, and were embedded in networks that were denser and where risky sex was more normative. Compared to non-FSW partners, men with FSW partners felt less emotionally close to them, were more likely to believe the partner had never been tested for HIV, and were more likely to have sex with them under the influence of drugs or alcohol; however, they were not more likely to talk about using condoms or to use condoms with FSWs. Whether the relationship was considered “serious” was a stronger correlate of condom use than whether the partner was a FSW. Implications of these findings for HIV prevention efforts among homeless adults are discussed.     

HIV-risk practices among homeless and low-income housed mothers

BACKGROUND: Knowledge of human immunodeficiency virus (HIV) and its risk behaviors have not been systematically studied in homeless mothers. The identification of the factors associated with HIV-risk practices will guide interventions for low-income housed and homeless women. METHODS: We interviewed 220 homeless and 216 low-income housed mothers living in Worcester, Massachusetts, to gather information on demographic, psychosocial , and HIV-risk practice characteristics. We used standardized instruments and questions drawn from national surveys. The primary study outcome was high HIV-risk behavior. RESULTS: Although homeless mothers were more likely than low-income housed mothers to report first sexual contact at an early age, multiple partners during the last 6 months, and a history of intravenous drug use, homelessness was not associated with high HIV-risk practices. Both homeless and low-income housed mothers demonstrated misconceptions about HIV transmission through casual contact. Among high-risk women, approximately 75% perceived themselves as having low or no risk for contracting HIV. A history of childhood victimization, adult partner violence, or both placed women at a significantly increased likelihood of high HIV-risk practices. African American race, knowledge about HIV, and self-perception of risk were also significantly associated with high-risk practices. CONCLUSIONS: Homeless mothers are a subgroup of poor women at high risk for HIV and should be targeted for preventive interventions. In addition, there are potentially modifiable factors associated with HIV-risk practices in both low-income housed and homeless mothers that should be directly addressed.     

Revolving doors: imprisonment among the homeless and marginally housed population

OBJECTIVES: We studied a sample of homeless and marginally housed adults to examine whether a history of imprisonment was associated with differences in health status, drug use, and sexual behaviors among the homeless. METHODS: We interviewed 1426 community-based homeless and marginally housed adults. We used multivariate models to analyze factors associated with a history of imprisonment. RESULTS: Almost one fourth of participants (23.1%) had a history of imprisonment. Models that examined lifetime substance use showed cocaine use (odds ratio [OR]=1.67; 95% confidence interval [CI]=1.04, 2.70), heroin use (OR=1.51; 95% CI=1.07, 2.12), mental illness (OR=1.41; 95% CI=1.01, 1.96), HIV infection (OR=1.69; 95% CI=1.07, 2.64), and having had more than 100 sexual partners were associated with a history of imprisonment. Models that examined recent substance use showed past-year heroin use (OR = 1.65; 95% CI = 1.14, 2.38) and methamphetamine use (OR=1.49; 95% CI=1.00, 2.21) were associated with lifetime imprisonment. Currently selling drugs also was associated with lifetime imprisonment. CONCLUSIONS: Despite high levels of health risks among all homeless and marginally housed people, the levels among homeless former prisoners were even higher. Efforts to eradicate homelessness also must include the unmet needs of inmates who are released from prison.     

Correlates of Sexual Risk among Recent Gay and Bisexual Immigrants from Western and Eastern Africa to the USA

We examined correlates of sexual risk among gay and bisexual men, who recently migrated from western and eastern African countries to the USA and lived in New York City and who are HIV negative or of unknown status. These men migrate from countries where same-sex sexuality is socially rejected and mostly illegal contributing to the motivation to migrate. Their background might predispose these men to engagement in sexual risk practices, while they are not specifically addressed in HIV prevention programming. Participants (N?=?62) reported in face-to-face interviews on pre- and postmigration experiences, psychosocial determinants of sexual risk, and current sexual practices. Operationalization of sexual risk was based on the number of men with whom they had condomless receptive and/or insertive anal sex. Over a third of the men reported always having used condoms in the past year; among the other men, sexual risk varied. Multivariate analyses showed that sexual risk was lower among men with a stronger motivation to avoid HIV infection and higher among men who currently engaged in transactional sex. Further analyses indicated that housing instability was independently associated with reduced motivation to avoid HIV infection and with engagement in transactional sex in the USA. In recent western and eastern African gay and bisexual immigrants to the USA, structural factors, including housing instability, are strongly associated with sexual risk.     

The association between history of violence and HIV risk: a cross-sectional study of HIV-negative incarcerated women in Connecticut.

PURPOSE: We examine the association between history of violence and risk for HIV infection among incarcerated women. Specifically, we consider physical violence and rape as they relate to unprotected sex with male primary and nonprimary (male or female) sexual partners among a sample of HIV negative female inmates (n = 1,588) housed in Connecticut's sole correctional facility for women between November 1994 and October 1996. METHODS: A supplement to the mandatory Connecticut Department of Correction Inmate Medical Screening/Health History was used to collect information on each woman's background, history of violence, and unprotected sex practices. Multivariate logistic regression was used to determine the associations between violence and unprotected sex by partner type. RESULTS: Experiencing any violence was significantly associated with increased odds of unprotected sex with one's primary partner, even after controlling for race, history of sex work, drug use, employment status, and having other nonprimary partners. Of particular importance was having a history of physical violence. History of violence was not significantly associated with unprotected sex with nonprimary partners. CONCLUSIONS: These findings demonstrate the considerable vulnerability of incarcerated women to violence and suggest that this history is associated with increased unprotected sex practices, especially with male primary partners. HIV prevention interventions among women should take experiences of violence into account. Conversely, violence prevention and interventions aimed at coping with violence can be a part of the HIV prevention agenda for incarcerated women. Future longitudinal research can confirm the relationships of violence to HIV risk in women.     

Reducing risky sexual behavior and substance use among currently and formerly homeless adults living with HIV

Objectives. We examined the efficacy of the Healthy Living Program in reducing risky sexual behavior and substance use among adults with HIV infection who were marginally housed (i.e., homeless at some point over a 37-month period).Methods. We had previously conducted a randomized controlled trial with 936 adults living with HIV infection. In that study, 3 intervention modules of 5 sessions each addressed different goals: reducing risky sexual acts and drug use, improving the quality of life, and adhering to healthful behaviors. Participants were interviewed at baseline and at 5, 10, 15, 20, and 25 months; 746 completed 4 or more assessments. In this study, we analyzed sexual behavior and drug use outcomes for the 35% (n = 270 of 767) of participants who were considered marginally housed.Results. Among the marginally housed participants, there were significantly greater reductions in unprotected risky sexual acts, the number of sexual partners of HIV negative or unknown serostatus, alcohol or marijuana use, and hard drug use among the intervention group than among the control group.Conclusions. Intensive, skill-focused intervention programs may improve the lives of marginally housed adults living with HIV infection.The rate of HIV infection among homeless adults in the United States ranges between 10.5% and 21%,^1–3 a rate 20 to 40 times higher than that among nonhomeless adults. Risky sexual acts are often associated with alcohol and drug use among the homeless, as they are among housed adults.^4–7 Injection drug users who are marginally housed (i.e., homeless at some time during the past 37 months) use shooting galleries and perform sex work twice as often as stably housed injection drug users.⁷ Given these heightened risks, it is critical that HIV-positive homeless and marginally housed adults receive interventions to reduce HIV transmission.Efficacious HIV prevention programs are available for homeless persons of unknown serostatus^8–12; however, no program has targeted adults living with HIV. Building on other prevention programs for HIV-positive persons^13–16 and informed by extensive preliminary qualitative work,¹⁷ the National Institute of Mental Health''s Healthy Living Project was designed for adults living with HIV infection who continued to engage in risky sexual acts after learning their serostatus.¹⁸ In previous analyses of this intervention, exposure to the Healthy Living Project helped adults living with HIV to significantly reduce their numbers of HIV-negative partners or partners of unknown serostatus, increase their condom use, and reduce substance abuse.^19,20 We analyzed the impact of the Healthy Living Project on a subsample of marginally housed adults living with HIV.Surviving while homeless is an all-consuming process, and the resources available to alter habitual sexual and drug behaviors are scarce. Under these stressful conditions, it was unclear whether a behavioral intervention would influence the daily routines of those without stable housing.We defined study participants who were homeless at any point over a period of 37 months as being marginally housed. Longitudinal studies have recently demonstrated that homelessness is usually sporadic.^7,21 In our study, the participants moved in and out of homelessness; only 4 of them remained homeless over the course of the entire study. The primary transmission behaviors examined were risky sexual behavior and drug use.     

Psychiatric symptoms, health services, and HIV risk factors among homeless women

The authors determined whether psychiatric symptoms and lack of health and/or social services contacts were associated with HIV risk behaviors among a probability sample of homeless women. Women were interviewed regarding socioeconomic indicators, psychiatric symptoms, health and/or social services contacts, and past-year HIV risk behaviors. Overall, 8 percent of the women injected drugs, 64 percent engaged in unprotected sex, and 22 percent traded sex. Multiple logistic regression results revealed that substance abuse was positively associated with injection drug use and trading sex. Homeless women with case managers were less likely to inject drugs. Although barriers to obtaining drug treatment were associated with trading sex, women attending self-help meetings for substance abuse were also more likely to trade sex. Homeless women who are substance abusers are vulnerable to HIV risk behaviors. Risk reduction interventions for homeless women should be implemented through substance abuse and intensive case management programs.     

High-risk behaviors among men who have sex with men in 6 US cities: baseline data from the EXPLORE Study

OBJECTIVES: We describe the prevalence of risk behaviors at baseline among men who have sex with men (MSM) who were enrolled in a randomized behavioral intervention trial conducted in 6 US cities. METHODS: Data analyses involved MSM who were negative for HIV antibodies and who reported having engaged in anal sex with 1 or more partners in the previous year. RESULTS: Among 4295 men, 48.0% and 54.9%, respectively, reported unprotected receptive and insertive anal sex in the previous 6 months. Unprotected sex was significantly more likely with 1 primary partner or multiple partners than with 1 nonprimary partner. Drug and alcohol use were significantly associated with unprotected anal sex. CONCLUSIONS: Our findings support the continued need for effective intervention strategies for MSM that address relationship status, serostatus of partners, and drug and alcohol use.
