Women who exchange sex for money or other goods, that is, female sex workers, are at increased risk of experiencing physical and sexual violence from both paying and intimate partners. Exposure to violence can be exacerbated by alcohol use and HIV/STI risk. The purpose of this study is to examine the efficacy of a HIV/STI risk reduction and enhanced HIV/STI risk reduction intervention at decreasing paying and intimate partner violence against Mongolian women who exchange sex and engage in harmful alcohol use. Women are recruited and randomized to either (a) four sessions of a relationship-based HIV/STI risk reduction intervention (n = 49), (b) the same HIV/STI risk reduction intervention plus two additional motivational interviewing sessions (n = 58), or (c) a four session control condition focused on wellness promotion (n = 59). All the respondents complete assessments at baseline (preintervention) as well as at immediate posttest, 3 and 6 months postintervention. A multilevel logistic model finds that women who participated in the HIV/STI risk reduction group (OR = 0.14, p < .00), HIV/STI risk reduction and motivational interview group (OR = 0.46, p = .02), and wellness (OR = 0.20, p < .00) group reduced their exposure to physical and sexual violence in the past 90 days. No significant differences in effects are observed between conditions. This study demonstrates the efficacy of a relationship-based HIV/STI risk reduction intervention, a relationship-based HIV/STI risk reduction intervention combined with motivational interviewing, and a wellness promotion intervention in reducing intimate and paying partner violence against women who exchange sex in Mongolia. The findings have significant implications for the impact of minimal intervention and the potential role of peer networks and social support in reducing women’s experiences of violence in resource poor settings.

OBJECTIVES We tested whether a structural intervention combining savings-led microfinance and HIV prevention components would achieve enhanced reductions in sexual risk among women engaging in street-based sex work in Ulaanbaatar, Mongolia, compared with an HIV prevention intervention alone. METHODS Between November 2011 and August 2012, we randomized 107 eligible women who completed baseline assessments to either a 4-session HIV sexual risk reduction intervention (HIVSRR) alone (n=50) or a 34-session HIVSRR plus a savings-led microfinance intervention (n=57). At 3- and 6-month follow-up assessments, participants reported unprotected acts of vaginal intercourse with paying partners and number of paying partners with whom they engaged in sexual intercourse in the previous 90 days. Using Poisson and zero-inflated Poisson model regressions, we examined the effects of assignment to treatment versus control condition on outcomes. RESULTS At 6-month follow-up, the HIVSRR plus microfinance participants reported significantly fewer paying sexual partners and were more likely to report zero unprotected vaginal sex acts with paying sexual partners. CONCLUSIONS Findings advance the HIV prevention repertoire for women, demonstrating that risk reduction may be achieved through a structural intervention that relies on asset building, including savings, and alternatives to income from sex work.

Persons living with HIV/AIDS (PLHA) of color are under-represented in AIDS clinical trials (ACTs), which may limit the generalizability of research findings and denies many individuals access to high levels of care and new treatments available through ACTs. Disproportionately low rates of recruitment in health care settings and by providers are a major barrier to ACTs for this group. Moreover, PLHA of color are more likely than their white peers to decline to participate, mainly due to fear and mistrust (although willingness is also high), negative social norms about ACTs, and difficulty navigating the unfamiliar ACT system. We describe a small number of successful behavioral and structural interventions to increase the participation of PLHA of color in screening for and enrollment into ACTs. HIV care settings, clinical trials sites, and trial sponsors are uniquely positioned to develop procedures, supports, and trials to increase the proportion of PLHA of color in ACTs.

OBJECTIVES We examined the efficacy of a peer-driven intervention to increase rates of screening for AIDS clinical trials among African Americans and Hispanics living with HIV/AIDS. METHODS We used a randomized controlled trial design to examine the efficacy of peer-driven intervention (6 hours of structured sessions and the opportunity to educate 3 peers) compared with a time-matched control intervention. Participants were recruited using respondent-driven sampling (n = 342; 43.9% female; 64.9% African American, 26.6% Hispanic). Most participants (93.3%) completed intervention sessions and 64.9% recruited or educated peers. Baseline and post-baseline interviews (94.4% completed) were computer-assisted. A mixed model was used to examine intervention effects on screening. RESULTS Screening was much more likely in the peer-driven intervention than in the control arm (adjusted odds ratio [AOR] = 55.0; z = 5.49, P < .001); about half of the participants in the intervention arm (46.0%) were screened compared with 1.6% of controls. The experience of recruiting and educating each peer also increased screening odds among those who were themselves recruited and educated by peers (AOR = 1.4; z = 2.06, P < .05). CONCLUSIONS Peer-driven intervention was highly efficacious in increasing AIDS clinical trial screening rates among African Americans and Hispanics living with HIV/AIDS.

Piloting a Savings-Led Microfinance Intervention with Women Engaging in Sex Work in Mongolia: Further Innovation for HIV Risk Reduction

Laura Cordisco Tsai; Susan S. Witte; Toivgoo Aira; Batsukh Altantsetseg; Marion Riedel

This paper describes a pilot study testing the feasibility of an innovative savings-led microfinance intervention in increasing the economic empowerment and reducing the sexual risk behavior of women engaging in sex work in Mongolia. Women’s economic vulnerability may increase their risk for HIV by compromising their ability to negotiate safer sex with partners and heightening the likelihood they will exchange sex for survival. Microfinance has been considered a potentially powerful structural HIV prevention strategy with women conducting sex work, as diversification of income sources may increase women’s capacity to negotiate safer transactional sex. With 50% of all reported female HIV cases in Mongolia detected among women engaging in sex work, direct prevention intervention with women conducting sex work represents an opportunity to prevent a potentially rapid increase in HIV infection in urban Mongolia. The piloted intervention consisted of a matched savings program in which matched savings could be used for business development or vocational education, combined with financial literacy and business development training for women engaging in sex work. Results of the pilot demonstrate participants’ increased confidence in their ability to manage finances, greater hope for pursuing vocational goals, moderate knowledge gains regarding financial literacy, and an initial transition from sex work to alternative income generation for five out of nine participants. The pilot findings highlight the potential for such an intervention and the need for a clinical trial testing the efficacy of savings-led microfinance programs in reducing HIV risk for women engaging in sex work in Mongolia.

Individuals from racial/ethnic minority backgrounds and women have not been proportionately represented in AIDS clinical trials (ACTs). There have been few intervention efforts to eliminate this health disparity. This paper reports on a brief behavioral intervention to increase rates of screening for ACTs in these groups. The study was exploratory and used a single-group pre/posttest design. A total of 580 persons living with HIV/AIDS (PLHA) were recruited (39% female; 56% African-American, 32% Latino/Hispanic). The intervention was efficacious: 25% attended screening. We identified the primary junctures where PLHA are lost in the screening process. Both group intervention sessions and an individual contact were associated with screening. Findings provide preliminary support for the intervention’s efficacy and the utility of combining group and individual intervention formats. Interventions of greater duration and intensity, and which address multiple levels of influence (e.g., social, structural), may be needed to increase screening rates further.

Introduction: This article provides an overview of the financial lives of women (n = 204) engaging in sex work in Ulaanbaatar, Mongolia. Methods: This paper presents findings from a computer-based, interviewer-administered baseline assessment administered with women recruited for participation in a randomized controlled trial testing the feasibility of a combined HIV risk reduction and savings-led microfinance intervention for women engaging in sex work in Mongolia. Findings: Findings demonstrate that most women are the primary financial providers for their households, using an array of earning strategies to provide for themselves and other dependents, with sex work often constituting the primary household income source. Financial instability in the lives of people engaging in sex work may increase their risk for HIV and STIs due to a compromised ability to negotiate safer sex with partners in times of economic crisis or need. High levels of financial responsibility for household welfare, when combined with low reported savings, the presence of debt, higher premiums offered for sex without a condom, and high levels of harmful alcohol use, may heighten womens risk for HIV and other STIs. Conclusion: Further research that documents the financial lives of people working in sex work is needed in order to understand the complex relationship between financial stability and engagement in sex work, and to inform the development and testing of structural HIV prevention interventions which target the economic determinants of risk. These findings highlight the importance of economic support programming for women engaged in sex work in Mongolia at a time of rapid economic change in Mongolia.

A substantial proportion of persons living with HIV/AIDS (PLHA) delay, decline, or discontinue antiretroviral therapy (ART) when it is medically indicated (40–45%), largely African-Americans and Latinos/Hispanics. This study explores the feasibility of locating PLHA, who are not on ART (PLHA-NOA) through clinics and peer-referral; compares the two cohorts on multi-level barriers to ART; and examines readiness to initiate/reinitiate ART, a predictor of treatment outcomes. We recruited adult HIV-infected African-American and Latino/Hispanic PLHA-NOA through HIV hospital clinics and peer-referral in 2012–2013. Participants were engaged in structured 1-h assessments with reliable/valid measures on barriers to ART. We found that recruitment through peers (63.2%, 60/95) was more feasible than in clinics (36.8%, 35/90). Participants were 48.0 years old and had lived with HIV for 14.7 years on average, and 56.8% had taken ART previously. Most (61.1%) were male and African-American (76.8%), and 23.2% were Latino/Hispanic. Peer-recruited participants were older, had lived with HIV longer, were less engaged in HIV care, and were more likely to have taken ART previously. The cohorts differed in reasons for discontinuing ART. Levels of ART knowledge were comparable between cohorts (68.5% correct), and there were no differences in attitudes toward ART (e.g., mistrust), which were in the neutral range. In bivariate linear regression, readiness for ART was negatively associated with physician mistrust (B = −10.4) and positively associated with self-efficacy (B = 5.5), positive outcome expectancies (B = 6.3), beliefs about personal necessity of ART (B = 17.5), and positive internal norms (B = 7.9). This study demonstrates the feasibility of engaging this vulnerable population through peer-referral. Peer-recruited PLHA evidence particularly high rates of risk factors compared to those in hospital clinics. Interventions to support ART initiation and continuation are sorely needed for both subgroups.

“I Thought There Was No Hope for Me”: A Behavioral Intervention for Urban Mothers With Problem Drinking

Rebecca de Guzman; Noelle R. Leonard; Marya Gwadz; Rebecca Young; Amanda S. Ritchie; Gricel N. Arredondo; Marion Riedel

In this article, the authors evaluate the effects of a behavioral intervention for mothers with problem drinking who were infected with, or at risk for, HIV. They randomly selected 25 mothers from a larger longitudinal randomized controlled intervention trial for a qualitative interview. The authors found that mothers’ participation in the program was facilitated by the development of a strong therapeutic alliance with the intervention facilitator and the use of a harm reduction approach toward alcohol and/or drug abuse. Mothers also reported that training in coping skills and the emphasis on parent-adolescent relationships were beneficial for program engagement and behavior change. The authors conclude from these results that treatment approaches that take into account the complexity of urban mothers’ lives and substance use patterns can successfully engage and treat these women at high risk for adverse outcomes.

This article evaluates the efficacy of a 14-session social-cognitive behavioral intervention on problem drinking (and where applicable, drug use) among urban HIV-infected and uninfected mothers, in comparison to a single-session social/motivational intervention, and explores the relationships of initial substance use problem severity and HIV status to efficacy. A randomized controlled trial design was used. Participants (N = 118) were mothers with problem drinking, both HIV-infected (55%) and uninfected, and primarily from racial/ethnic minority and low socioeconomic status backgrounds. Participants were interviewed five times over 18 months. Both intervention arms yielded reductions in alcohol and drug use frequency, alcohol quantity, and alcohol/drug problems, with moderate effect sizes. Those with greater initial substance use maintained reductions over a longer period of time in response to the more intensive social-cognitive intervention. Treatment efficacy did not vary by HIV status. The utility of targeting intervention intensity to the level of substance use is supported.
