Gender-specific correlates of sex trade among homeless and marginally housed individuals in San Francisco

Communicable disease among people experiencing homelessness in California

California has a large population of people experiencing homelessness (PEH) that is characterised by a high proportion of people who are unsheltered and chronically homeless. PEH are at increased risk of communicable diseases due to multiple, intersecting factors, including increased exposures, comorbid conditions including substance use disorder and mental illness and lack of access to hygiene and healthcare facilities. Data available for several communicable diseases show that PEH in California experiences an increased burden of communicable diseases compared to people not experiencing homelessness. Public health agencies face unique challenges in serving this population. Efforts to reduce homelessness, increase access to health care for PEH, enhance data availability and strengthen partnerships among agencies serving PEH can help reduce the disparity in communicable disease burden faced by PEH.

Comparison of Selected Sociodemographic Characteristics and Sexual Risk Behaviors of Black/African American Men Who Have Sex with Men Only and Men Who Have Sex with Men and Women, Southeastern United States, 2013-2016

PURPOSE

Compare selected sociodemographic and sexual risk characteristics of black/African American (black) men who have sex with men only (MSMO) and men who have sex with men and women (MSMW) in the southeastern United States (the South).

METHODS

We conducted bivariate and multivariable analyses to explore the sociodemographic characteristics and sexual risk behaviors of 584 MSMW and MSMO in the South.

RESULTS

MSMW had lesser odds of having a college or graduate degree (aOR = 0.32; 95% CI = 0.19, 0.54) and having > 2 male oral sex partners (aOR = 0.20; 95% CI = 0.08, 0.48) compared to MSMO. MSMW had greater odds of being homeless (aOR = 3.11; 95% CI = 1.80, 5.38) and selecting "top" sexual position (aOR = 1.70; 95% CI = 1.07, 2.72) compared to MSMO.

CONCLUSION

MSMW in the South experience social and structural factors that may affect their risk for HIV infection. Strategies to address these factors should be considered in prevention and care efforts for this population.

Arrest and Trait Aggression Correlates of Emergency Department Use

This study examined the associations between arrest and incarceration, trait aggression, and emergency department (ED) use. Data were collected from 525 clients who visited the Center for Behavioral Research and Services in Long Beach, CA, using the following instruments: Risk Behavior Assessment, Risk Behavior Follow-Up Assessment, the Aggression Questionnaire (AQ), the Displaced AQ, and the parole and Legal Status section of the Addiction Severity Index. The bivariate analysis suggested that ED use was significantly associated with trait aggression and trait-displaced aggression among those with a history of incarceration. In the logistic regression, weapons offenses, manslaughter/homicide, being male, and being Black were significantly associated with ED use. Identification and management of aggressive trait personality are important in improving the management of postrelease care in transition to clinical networks and community-based health care settings.

Condomless Sex and Psychiatric Comorbidity in the Context of Constrained Survival Choices: A Longitudinal Study Among Homeless and Unstably Housed Women

We sought to identify the prevalence and independent correlates of condomless sex within a cohort of community-recruited homeless and unstably housed cisgender adult women who were followed biannually for 3 years (N = 143 HIV+ , N = 139 HIV-). Nearly half (44%) of participants reported condomless sex in the 6 months before baseline, which increased to 65% throughout the study period. After adjusting for having a primary partner, longitudinal odds of condomless sex among women with HIV were significantly higher among those reporting < daily use of alcohol or cannabis (AOR = 2.09, p =.002, and 1.88, p =.005, respectively) and PTSD (AOR = 1.66, p =.034). Among women without HIV, adjusted longitudinal odds of condomless sex were significantly higher for those reporting < daily methamphetamine use (AOR = 2.02, p =.012), panic attack (AOR = 1.74, p =.029), and homelessness (AOR = 1.67, p = .006). Associations were slightly attenuated when adjusting for sex exchange. Targeted HIV/STI programs for unstably housed women should address anxiety and trauma disorders, infrequent substance use, and housing challenges.

POPULAÇÃO EM SITUAÇÃO DE RUA, VULNERABILIDADES E DROGAS: UMA REVISÃO SISTEMÁTICA

Resumo O presente artigo tem como objetivo realizar uma revisão sistemática sobre os determinantes pobreza, estigma, raça e vulnerabilidade entre a população em situação de rua usuária de drogas. Para tal, foi realizada uma revisão sistemática utilizando as bases de dados Scielo Br, PepSiC, PubMed e Redalyc. Ao final dos procedimentos foram selecionados 79 artigos. Foi percebida diferença significativa dos estudos realizados nos Estados Unidos e os latino-americanos. Enquanto os primeiros tendem a priorizar estudos com grandes amostras com o foco na análise de riscos e na quantificação de categorias, as pesquisas latinas tendem a contextualizar as condições de desigualdade e pobreza, ao passo que utilizam metodologias participativas e se aproximam de uma análise das vulnerabilidades. Os resultados indicam discussões ainda incipientes que articulem tais categorias e que pouco englobam as diversas vulnerabilidades a que esses sujeitos estão expostos ao longo de suas vidas, bem como apontam para a necessidade de uma nova categoria analítica de compreensão.

Structural factors associated with methamphetamine smoking among female sex workers in Tijuana, Mexico

INTRODUCTION AND AIMS

Smoking methamphetamine is associated with increased risk of HIV among female sex workers (FSW). The structural context of substance use is an important shaper of individual behaviour; however, structural determinants of methamphetamine use among FSWs are largely unknown. We identified individual, structural and neighbourhood factors associated with smoking methamphetamine among FSWs in the border city of Tijuana, Baja California, Mexico.

DESIGN AND METHODS

A prospective cohort of 301 FSWs sampled from indoor and outdoor sex work venues throughout Tijuana participated in quantitative surveys on behaviours and mapping of home and work neighbourhoods across three visits. Multinomial logistic regression using generalised estimating equations identified individual, structural and neighbourhood variables associated with smoking methamphetamine.

RESULTS

Methamphetamine use, particularly smoking, was highly prevalent among FSWs. Over half (61%) of FSWs had ever used methamphetamine in their lifetime and at baseline, 38% currently smoked methamphetamine. Smoking methamphetamine daily was associated with living in the red light district [adjusted odds ratio (AOR) = 2.72, 95% confidence interval (CI) = 1.23-6.02] and with perceived homelessness, but only among women in a good financial situation (AOR = 4.08, 95% CI = 1.58-10.50). Smoking methamphetamine less than daily was associated with older age (AOR = 1.06, 95% CI = 1.02-1.10).

DISCUSSION AND CONCLUSIONS

Our findings point to the important dynamic between the residential environment and more severe methamphetamine use. FSWs may prioritise the purchase of methamphetamine over stable housing if they have the financial means. Given the high prevalence of smoking methamphetamine among FSWs in Tijuana, drug treatment options, especially for women living in the red light district, are needed.

Burden and correlates of mental health diagnoses among sex workers in an urban setting

Background

Women involved in both street-level and off-street sex work face disproportionate health and social inequities compared to the general population. While much research has focused on HIV and sexually transmitted infections (STIs) among sex workers, there remains a gap in evidence regarding the broader health issues faced by this population, including mental health. Given limited evidence describing the mental health of women in sex work, our objective was to evaluate the burden and correlates of mental health diagnoses among this population in Vancouver, Canada.

Methods

An Evaluation of Sex Workers Health Access (AESHA) is a prospective, community-based cohort of on- and off-street women in sex work in Vancouver, Canada. Participants complete interviewer-administered questionnaires semi-annually. We analyzed the lifetime burden and correlates of self-reported mental health diagnoses using bivariate and multivariable logistic regression.

Results

Among 692 sex workers enrolled between January 2010 and February 2013, 338 (48.8%) reported ever being diagnosed with a mental health issue, with the most common diagnoses being depression (35.1%) and anxiety (19.9%). In multivariable analysis, women with mental health diagnoses were more likely to identify as a sexual/gender minority (LGBTQ) [AOR=2.56, 95% CI: 1.72—3.81], to use non-injection drugs [AOR=1.85, 95% CI: 1.12—3.08], to have experienced childhood physical/sexual trauma [AOR=2.90, 95% CI: 1.89—4.45], and work in informal indoor [AOR=1.94, 95% CI: 1.12 – 3.40] or street/public spaces [AOR=1.76, 95% CI: 1.03–2.99].

Conclusions

This analysis highlights the disproportionate mental health burden experienced by women in sex work, particularly among those identifying as a sexual/gender minority, those who use drugs, and those who work in informal indoor venues and street/public spaces. Evidence-informed interventions tailored to sex workers that address intersections between trauma and mental health should be further explored, alongside policies to foster access to safer workspaces and health services.

Violence, trauma and living with HIV: Longitudinal predictors of initiating crystal methamphetamine injection among sex workers

BACKGROUND

Despite rapid increases in crystal methamphetamine (CM) use worldwide and established gendered patterns of use, empirical research on CM injection initiation among sex workers is limited. Given the wide range of harms associated with CM, alongside stimulant effects including sexual dis-inhibition and prolonged awake-ness, this study aimed to longitudinally investigate socio-structural predictors of initiating CM injection among sex workers in Vancouver, Canada.

METHODS

Data (2010-2014) were drawn from a community-based cohort of women sex workers: AESHA (An Evaluation of Sex Workers Health Access). Participants completed bi-annual interviewer-administered questionnaires and HIV/STI testing. Kaplan Meier methods and Cox proportional hazards regression were used to model predictors of CM injection initiation among CM injection-naïve participants.

RESULTS

Of 455 participants eligible at baseline, 14.3% (n=65) injected CM for the first time over follow-up, with an incidence density of 6.79 per 100 person-years (95% Confidence Interval [CI] 5.30-8.69). In multivariable analysis, injection heroin use (Adjusted Hazard Ratio [AHR] 6.11; 95%CI 3.24-11.52), having an intimate partner who injects drugs (AHR 2.93; 95%CI 1.57-5.46), workplace violence (AHR 2.85; 95%CI 1.74-4.67), HIV seropositivity (AHR 2.69; 95%CI 1.45-5.00), and childhood abuse (AHR 1.86; 95%CI 0.99-3.49) were independently associated with initiating CM injection.

CONCLUSIONS

Findings underscore the gendered and social risk environment of CM injection initiation among sex workers. The strong influences of historical/workplace violence, coupled with heroin injection (known to be self-medicating for post-traumatic stress) as a primary risk pathway, emphasize the urgency of increasing access to integrated, trauma-informed addiction treatment and HIV care for marginalized women.

Recruitment and retention of homeless individuals with mental illness in a housing first intervention study

Background

Homeless individuals with mental illness are challenging to recruit and retain in longitudinal research studies. The present study uses information from the Vancouver site of a Canadian multi-city longitudinal randomized controlled trial on housing first interventions for homeless individuals. We were able to recruit 500 participants and retain large number of homeless individuals with mental illness; 92% of the participants completed the 6-month follow up interview, 84% the 24-month follow up, while 80% completed all follow-up visits of the study.

Purpose

In this article, we describe the strategies and practices that we considered as critical for successful recruitment and retention or participants in the study.

Methods

We discuss issues pertaining to research staff hiring and training, involvement of peers, relationship building with research participants, and the use of technology and social media, and managing challenging situations in the context of recruitment and retention of marginalized individuals.

Conclusions

Recruitment and retention of homeless participant with mental illness in longitudinal studies is feasible. It requires flexible, unconventional and culturally competent strategies. Longitudinal research projects with vulnerable and hidden populations may benefit from extensive outreach work and collaborative approaches that are based on attitudes of mutual respect, contextual knowledge and trust.

Pilot Test of an Adapted, Evidence-Based HIV Sexual Risk Reduction Intervention for Homeless Women

Women experiencing homelessness are at heightened risk for HIV, yet risk reduction interventions specifically designed for this population are lacking. This study reports on a pilot efficacy trial of a brief evidence-based intervention, Sister To Sister (STS), that we specifically adapted for homeless women in the temporary/emergency settings where they typically seek services. Seventy-nine women, recruited from three service sites in Los Angeles County, were assigned to the 40-min adapted STS intervention or an information-only control group. At 30-day follow-up, intervention participants reported significantly greater condom use, intentions to use condoms, and sexual impulse control (as well as marginally higher positive condom beliefs and condom self-efficacy) compared to control participants. Results provide preliminary evidence that HIV risk reduction can be achieved for homeless women through a brief skill-based intervention. A randomized controlled trial employing a longer follow-up period to monitor outcomes will be necessary to determine efficacy of the adapted intervention.

The Impact of Homelessness and Incarceration on Women's Health

Female inmates have multiple challenges during incarceration and as they transition into the community including: barriers to accessing health care within correctional facilities, poor transitional preparation preceding release, and inadequate continuity of health care after release. This qualitative study explored the health-seeking experiences and the health and housing needs of female inmates. Four focus groups were conducted in a remand facility in Canada. Women described poor health at entry to the correctional system and viewed incarceration as a means to access health care services. Transition back into the community represented a crossroad that was dependent on the stability of housing status. These findings support gender-sensitive health and housing programs to reduce addictions, recidivism, and poor health among this vulnerable population.

High Rates of Herpes Simplex Virus Type 2 Infection in Homeless Women: Informing Public Health Strategies

BACKGROUND

Homeless and unstably housed women living in an urban setting are at risk for sexually transmitted diseases, yet the seroprevalence and correlates of herpes simplex virus type 2 (HSV-2) specific to impoverished women are poorly understood.

MATERIALS AND METHODS

Between April and October 2010, we conducted a cross-sectional analysis of sociodemographic, structural, and behavioral factors associated with prevalent HSV-2 infection (recent and historical infections) within a community-recruited cohort of homeless and unstably housed women. Logistic regression modeling was used to identify independent sociobehavioral correlates of HSV-2 infection.

RESULTS

Among 213 women (114 HIV positive and 99 HIV negative), the median age was 49, 48% were African American, and 63% had completed high school. HSV-2 seroprevalence was 88%, and only 17% of infected women were aware of their infection. In adjusted analysis, odds of HSV-2 infection were significantly higher for those reporting at-risk drinking (adjusted odds ratio [AOR] = 7.04; 95% confidence interval [CI] = 1.59, 67.91), heterosexual orientation (AOR = 4.56; 95% CI = 1.81, 11.69), and for those who were HIV positive (AOR = 3.64; 95% CI = 1.43, 10.30). Odds of HSV-2 infection decreased as current income increased (AOR for each $500 monthly increase = 0.90; 95% CI = 0.78, 0.997).

CONCLUSIONS

There is an extremely high seroprevalence of HSV-2 infection among homeless and unstably housed women, and most are unaware of their HSV-2 status. Screening all unstably housed women for HSV-2 infection, with additional counseling for sexual risk and alcohol use, may lead to the identification of more infections and be a first step in reducing additional disease transmission.

Understanding Consistent Condom Use Among Homeless Men Who Have Sex with Women and Engage in Multiple Sexual Partnerships: A Path Analysis

Consistent condom use is the main strategy aimed at preventing individuals from acquiring HIV through sexual intercourse. The mechanism of consistent condom use among a high-risk homeless subpopulation-homeless men who have sex with women and also engage in multiple sexual partnerships-remains unclear. This study identified 182 homeless men who engaged in multiple sexual partnerships from a representative sample of homeless men, who self-identified as heterosexual, using meal line services in Downtown Los Angeles' Skid Row area. Information such as participants' condom use psychosocial correlates, sexual risk behaviors, and social network characteristics were collected. Results suggested that condom efficacy is a potential intervening mechanism through which condom attitudes (β = -0.199; p = 0.005) and depression (β = -0.156; p = 0.029) are associated with an individual's consistent condom use. Having more network members with whom participants talked about HIV prevention (β = 0.051; p = 0.006) was also found to be associated with an individual's consistent condom use. HIV prevention programs should focus on increasing their condom efficacy to help reduce HIV risks among this vulnerable homeless subpopulation.

Prevalence and factors associated with sex trading in the year prior to entering treatment for drug misuse in England

BACKGROUND

This study estimates the past year prevalence of and factors associated with sex trading (offering sex for money, drugs or something else) among 1796 men and women presenting to 342 drug misuse treatment agencies in England, and identifies service development and delivery implications.

METHODS

Secondary analysis of baseline data from a prospective cohort was conducted. Short Form-12 measured mental and physical wellbeing, psychiatric diagnoses were self-reported and the circumstances, motivation and readiness tool assessed readiness for/pressure to enter treatment. Logistic regression models determined associations with sex trading separately by sex. Inverse probability population weights were calculated, utilising demographics from the National Drug Treatment Monitoring System and agency specific data collection windows.

RESULTS

The estimated prevalence rate of sex trading in the past 12 months was 5.1% (15.0% for women and 2.1% for men). For women, adjusted models identified crack use (aOR 1.83, 95% CI 1.22-2.74, p=0.004), previous treatment (aOR 3.00, 95% CI 1.31-6.86, p=0.010) and greater readiness for treatment (aOR 1.12, 95% CI 1.01-1.24, p=0.027) as independently associated with sex trading. For men, lower mental wellbeing (aOR 0.97, 95% CI 0.94-0.99, p=0.030) was independently associated and marginal effects were identified for syringe sharing (aOR 2.89, 95% CI 0.94-8.86, p=0.064) and unprotected sex (aOR 2.23, 95% CI 0.95-5.26, p=0.065).

CONCLUSIONS

Sex trading among drug misusers is associated with additional health risks and specific treatment needs. Given the scale of the problem it is important that treatment providers have the competencies to adequately address the issue and provide accessible and appropriate services.

Syndemics of psychosocial problems and HIV risk: A systematic review of empirical tests of the disease interaction concept

In the theory of syndemics, diseases co-occur in particular temporal or geographical contexts due to harmful social conditions (disease concentration) and interact at the level of populations and individuals, with mutually enhancing deleterious consequences for health (disease interaction). This theory has widespread adherents in the field, but the extent to which there is empirical support for the concept of disease interaction remains unclear. In January 2015 we systematically searched 7 bibliographic databases and tracked citations to highly cited publications associated with the theory of syndemics. Of the 783 records, we ultimately included 34 published journal articles, 5 dissertations, and 1 conference abstract. Most studies were based on a cross-sectional design (32 [80%]), were conducted in the U.S. (32 [80%]), and focused on men who have sex with men (21 [53%]). The most frequently studied psychosocial problems were related to mental health (33 [83%]), substance abuse (36 [90%]), and violence (27 [68%]); while the most frequently studied outcome variables were HIV transmission risk behaviors (29 [73%]) or HIV infection (9 [23%]). To test the disease interaction concept, 11 (28%) studies used some variation of a product term, with less than half of these (5/11 [45%]) providing sufficient information to interpret interaction both on an additive and on a multiplicative scale. The most frequently used specification (31 [78%]) to test the disease interaction concept was the sum score corresponding to the total count of psychosocial problems. Although the count variable approach does not test hypotheses about interactions between psychosocial problems, these studies were much more likely than others (14/31 [45%] vs. 0/9 [0%]; χ2 = 6.25, P = 0.01) to incorporate language about "synergy" or "interaction" that was inconsistent with the statistical models used. Therefore, more evidence is needed to assess the extent to which diseases interact, either at the level of populations or individuals, to amplify HIV risk.

A new survey of methamphetamine users in treatment: who they are, why they like "meth," and why they need additional services

The quality and quantity of illicit methamphetamine has recently increased due to introduction of a new precursor, 1-phenyl-2-propanone (P2P). This paper updates the problems associated with methamphetamine use. Methamphetamine-using clients (N = 222) entering a Texas program participated in computer-assisted interviews in 2010 and 2011 about routes of administration, other drugs used, severity of dependence, mental and physical health, perceived risks and benefits of use, family history, and abuse and neglect experienced as children and adults. Special needs of this population include therapies for trauma, gender-focused counseling, safe housing, and prevention messages to discourage use of the drug.

Emergency room use after being released from incarceration

Background

This study investigates opiate use in mediating the impact of history of incarceration on emergency department (ED) use.

Method

Data were collected from 1,341 clients who underwent HIV and STI screening in an outpatient care center in Long Beach, California. The Risk Behavior Assessment (RBA, baseline) and Risk Behavior Follow-Up Assessment (RBFA, follow-up) were administered to each client with at least a three months interval between assessments.

Results

Of 1341 participants in the study, 931 (69.43%) reported previous incarceration. Having a history of incarceration was significantly associated with emergency room use as well as a history of sexually transmitted infections (STIs), injection drug use, opiate use, and survival sex trading, defined as sex for money or drugs. The relationship between previous incarceration and ED use was mediated by opiate use for men but not for women. The findings suggested that the effect of history of incarceration on ED use was exacerbated when the individuals were male and opiate users.

Conclusions

Targeted interventions in treatment and rehabilitation programs could help prevent unnecessary ED use and reduce the use of EDs through drug treatment during incarceration and after release.

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.

Basic subsistence needs and overall health among human immunodeficiency virus-infected homeless and unstably housed women

Some gender differences in the progression of human immunodeficiency virus (HIV) infection have been attributed to delayed treatment among women and the social context of poverty. Recent economic difficulties have led to multiple service cuts, highlighting the need to identify factors with the most influence on health in order to prioritize scarce resources. The aim of this study was to empirically rank factors that longitudinally impact the health status of HIV-infected homeless and unstably housed women. Study participants were recruited between 2002 and 2008 from community-based venues in San Francisco, California, and followed over time; marginal structural models and targeted variable importance were used to rank factors by their influence. In adjusted analysis, the factor with the strongest effect on overall mental health was unmet subsistence needs (i.e., food, hygiene, and shelter needs), followed by poor adherence to antiretroviral therapy, not having a close friend, and the use of crack cocaine. Factors with the strongest effects on physical health and gynecologic symptoms followed similar patterns. Within this population, an inability to meet basic subsistence needs has at least as much of an effect on overall health as adherence to antiretroviral therapy, suggesting that advances in HIV medicine will not fully benefit indigent women until their subsistence needs are met.

Crystal methamphetamine use among female street-based sex workers: Moving beyond individual-focused interventions

Given growing concern of the sexual risks associated with crystal methamphetamine use and the dearth of research characterizing the use of methamphetamine among street-based sex workers (FSWs), this study aimed to characterize the prevalence and individual, social, and structural contexts of crystal methamphetamine use among FSWs in a Canadian setting. Drawing on data from a prospective cohort, we constructed multivariate logistic models to examine independent correlates of crystal methamphetamine among FSWs over a two-year follow-up period using generalized estimating equations. Of a total of 255 street-based FSWs, 78 (32%) reported lifetime crystal methamphetamine use and 24% used crystal methamphetamine during the two-year follow-up period, with no significant associations between methamphetamine use and sexual risk patterns. In a final multivariate GEE model, FSWs who used crystal methamphetamine had a higher proportional odds of dual heroin injection (adjOR=2.98, 95%CI: 1.35-5.22), having a primary male sex partner who procures drugs for them (adjOR=1.79, 95%CI: 1.02-3.14), and working (adjOR=1.62, 95%CI: 1.04-2.65) and living (adjOR=1.41, 95%CI: 1.07-1.99) in marginalized public spaces. The findings highlight the crucial need to move beyond the individual to gender-focused safer environment interventions that mediate the physical and social risk environment of crystal methamphetamine use among FSWs.

Risk factors for homelessness and sex trade among incarcerated women: A Structural equation model

Incarcerated women are among the most vulnerable and perhaps the least studied populations in the US. Significant proportions of female inmates are substance users, and many living in unstable housing conditions or being homeless. Female inmates are often at high risk of engaging in sex exchange for drugs or housing needs. While a disproportionate number of incarcerated women have experienced childhood household adversities and maltreatments, the effects of these childhood experiences on psychosocial and behavioral outcomes of this population in later life. We apply a life course perspective to examine these pathways in a sample of incarcerated women in Cook County, Illinois. Findings demonstrated lasting, but differential, effects of household adversities and childhood abuse on subsequent life risks and opportunities among these women.

Polydrug use among IDUs in Tijuana, Mexico: correlates of methamphetamine use and route of administration by gender

Tijuana is situated on the Mexico-USA border adjacent to San Diego, CA, on a major drug trafficking route. Increased methamphetamine trafficking in recent years has created a local consumption market. We examined factors associated with methamphetamine use and routes of administration by gender among injection drug users (IDUs). From 2006-2007, IDUs > or =18 years old in Tijuana were recruited using respondent-driven sampling, interviewed, and tested for HIV, syphilis, and TB. Logistic regression was used to assess associations with methamphetamine use (past 6 months), stratified by gender. Among 1,056 participants, methamphetamine use was more commonly reported among females compared to males (80% vs. 68%, p < 0.01), particularly, methamphetamine smoking (57% vs. 34%; p < 0.01). Among females (N = 158), being aged >35 years (AOR, 0.2; 95% CI, 0.1-0.6) was associated with methamphetamine use. Among males (N = 898), being aged >35 years (AOR, 0.5; 95% CI, 0.3-0.6), homeless (AOR, 1.4 (0.9-2.2)), and ever reporting sex with another male (MSM; AOR, 1.9; 95% CI, 1.4-2.7) were associated with methamphetamine use. Among males, a history of MSM was associated with injection, while sex trade and >2 casual sex partners were associated with multiple routes of administration. HIV was higher among both males and females reporting injection as the only route of methamphetamine administration. Methamphetamine use is highly prevalent among IDUs in Tijuana, especially among females. Routes of administration differed by gender and subgroup which has important implications for tailoring harm reduction interventions and drug abuse treatment.

Behaviorally bisexual men and their risk behaviors with men and women

Gay and bisexual men are often treated as a homogenous group; however, there may be important differences between them. In addition, behaviorally bisexual men are a potential source of HIV infection for heterosexual women. In this study, we compared 97 men who have sex with men only (MSM) to 175 men who have sex with men and women (MSMW). We also compared the 175 MSMW to 772 men who have sex with women only (MSW). Bivariate and multiple logistic regression analyses were performed to assess correlates of MSMW risk behaviors with men and with women as well as whether MSMW, compared with MSW, engaged in more risky behaviors with women. Compared with MSM, MSMW were less likely to be HIV-positive or to engage in unprotected receptive anal intercourse. In contrast, MSMW were more likely than MSW to be HIV-positive and to engage in anal intercourse with their female partners; however, rates of unprotected anal intercourse were similar. The study findings suggest that there may be important differences in HIV risk behaviors and HIV prevalence between MSM and MSMW as well as between MSMW and MSW.

Transactional sex among men and women in the south at high risk for HIV and other STIs

Transactional sex refers to selling sex (exchanging sex for money, drugs, food, shelter, or other items) or purchasing sex (exchanging money, drugs, food, shelter, or other items for sex). These activities have been associated with a higher risk for HIV and other sexually transmitted infections in a variety of populations and settings. This paper examines correlates of purchasing and selling sex in a large sample of drug users, men who have sex with men, and sex partners of these groups. Using respondent-driven sampling, participants were recruited between 2005 and 2008 in two urban and two rural counties in North Carolina. We used multiple logistic regressions to examine separate models for selling and purchasing sex in men and women. In addition, we estimated direct and indirect associations among independent variables in the logistic regression models and transactional sex using structural equation models. The analysis shows that factors associated with women selling and buying sex include being homeless, use of stimulants, bisexual behavior, and neighborhood disorder. There was also a significant difference by race. For men, the factors associated with selling and buying sex include being homeless, bisexual behavior, and not being in a relationship. Although neighborhood violence and disorder show significance in bivariate associations with the outcome, these associations disappear in the structural equation models.

Gender-specific correlates of incarceration among marginally housed individuals in San Francisco

OBJECTIVES

We assessed how different patterns of housing instability affect incarceration and whether correlates of incarceration are gender specific.

METHODS

We used multivariate logistic regression to assess associations between patterns of housing instability and recent jail stays among a reproducible sample of 1175 marginally housed adults in San Francisco, California.

RESULTS

Over the previous year, 71% of men and 21% of women in the sample reported jail stays. Among women, long-term single-room occupancy hotel stays ( > 90 days) were protective for incarceration. Stays in the street were associated with incarceration among both genders, but among men, short-term (i.e., <or= 90 days) street stays were associated with the highest odds of incarceration, and among women, long-term street stays were most correlated with incarceration. Sex trade increased the odds of incarceration among men only; recent drug use was associated with incarceration among both genders.

CONCLUSIONS

Correlates of incarceration differed by gender, and patterns of housing instability differentially affected incarceration for men and women. Policies to improve housing options and drug treatment for the urban poor are critical to breaking the cycle of incarceration and homelessness and improving health outcomes.

Profile of cocaine and crack users in Brazil

This article aims to systematize the profile of cocaine and crack users in Brazil. The study adopted a literature review of the MEDLINE, LILACS, Cochrane Library databases and CAPES thesis/dissertation database. Data were grouped in thematic categories: national household surveys, surveys of specific population groups, profile of patients that seek treatment, and mortality and morbidity. Within each category the principal findings from the Brazilian literature were described and then discussed. The article concludes that the information on cocaine and crack consumption in Brazil is still incipient, but that the scientific community can already draw on a relevant theoretical corpus that can be used to update current public policies on this issue.

Poverty, unstable housing, and HIV infection among women living in the United States

Women who are HIV positive incur a higher risk of mortality than men who are HIV positive, a difference which is primarily based in the social context of poverty. Economic crises that lead to homelessness, unmet subsistence needs, and sex exchange often reorder priorities among women with HIV infection, de-emphasizing consistent medical care or the use of antiretroviral therapy. High rates of mental illness, drug use, and victimization further increase health and safety risks. HIV prevention messages highlighting education and behavior change insufficiently address the predicament of indigent women where constrained survival choices in the context of poverty may take precedence over safe behaviors. In this article, we highlight the risks of poor and unstably housed women to clarify the context in which risks occur. Suggestions for service provision are offered with the understanding that providers may have limited time and expertise to meet the entire array of needs for impoverished women.
