The impact of a microsavings intervention on reducing violence against women engaged in sex work: a randomized controlled study

Strategies and Interventions Used to Prevent Violence Against Sex Workers in the United States: A Scoping Review Using the Social-Ecological Model

Structural factors in the United States, such as criminalization, contribute to disproportionate rates of violence against sex workers and subsequent risk of adverse health outcomes. There is a clear need for systemic interventions and risk reduction strategies to reduce violence in this population. To inform next steps in prevention, this scoping review provides an overview of the literature on violence prevention efforts targeting sex workers in the United States, mapped out according to the social-ecological model (SEM). A comprehensive search of peer-reviewed literature across five databases with no limit on publication date yielded 2,372 documents. Studies were eligible for inclusion if they focused on the U.S. population of sex workers and had a clearly defined aim or purpose of exploring, describing, or evaluating sex work violence prevention interventions or risk reduction strategies. Twelve studies met all eligibility criteria and were selected. Only two of the studies evaluated sexual violence prevention interventions, while the remaining 10 explored strategies sex workers use to minimize the risk of violence. Most research focused on female sex workers, violence from paying clients, and prevention at the individual level of the SEM. Our findings suggest a need for additional violence prevention interventions tailored for diverse groups of sex workers and cognizant of the overlapping forms of violence they face. This scoping review contributes to the limited body of research on the prevention of violence against sex workers in the United States by providing future directions for research and program development that span across the SEM.

Reducing Partner Violence Against Women who Exchange Sex and use Drugs through a Combination Microfinance and HIV Risk Reduction Intervention: A Cluster Randomized Trial

Women who exchange sex and use drugs (WESUD) are at high risk for HIV infection and partner violence. The few tested interventions at the intersection of HIV and IPV show mixed results. This analysis examined the impact of a combination HIV risk reduction (HIVRR) and microfinance (MF) intervention on reported paying and intimate partner violence against WESUD in Kazakhstan. This cluster randomized controlled trial enrolled 354 women from 2015 to 2018 and randomized them to either a combination of HIVRR and MF intervention or HIVRR alone. Outcomes were assessed at four time points over 15 months. Logistic regression within a Bayesian approach assessed change in odds ratio (OR) of recent physical, psychological, or sexual violence perpetrated by current or past intimate partners; and paying partners/clients by study arm over time. Compared to the control arm, the combination intervention decreased the odds of participants experiencing physical violence from past intimate partners by 14% (OR = 0.861, p = 0.049). Women in the intervention group reported significantly lower rates of sexual violence from paying partners (HIVRR + MF - HIVRR: 25.9%; OR = 0.741, p = 0.019) at 12-month follow-up. No significant differences in rates from current intimate partners were found. A combination HIVRR and microfinance intervention may reduce gender-based violence from paying and intimate partners among WESUD above and beyond HIVRR interventions alone. Future research should examine how microfinance reduces partner violence and how to implement combination interventions in diverse settings.

Association of gender-based violence with sexual and drug-related HIV risk among female sex workers who use drugs in Kazakhstan

BACKGROUND

Little is known about the prevalence of intimate partner violence (IPV) or client violence, and associated HIV risk among women who engage in sex work (WESW) and use drugs in Kazakhstan, despite a growing HIV epidemic.

METHODS

Women who reported engaging in sex work and using illicit drugs were recruited from Almaty and Temirtau, Kazakhstan between 2015 and 2017. A cross-sectional analysis was conducted to determine prevalence and correlates of physical and sexual violence perpetrated by intimate partners and clients. Associations between each type of violence with sexual and drug-related HIV risk behaviors were assessed with negative-binomial and logistic regression models, respectively.

RESULTS

Of the 400 women, 45% and 28% reported recent IPV and client violence, respectively. IPV and client violence was associated with a greater number of sex work clients [IPV: adjusted incidence rate ratio (aIRR)physical: 1.86, 1.28-2.71; aIRRsexual: 2.28, 1.56-3.35]; [client violence: aIRRphysical: 2.20, 1.44-3.42; aIRRsexual: 2.54, 1.72-3.83], and client violence was associated with greater frequency of condomless sex with clients [aIRRphysical: 2.33, 1.41-4.03; aIRRsexual: 2.16, 1.35-3.56]. Violence was not associated with injection drug use, despite exchanging sex for drugs being associated with higher odds of violence.

CONCLUSION

HIV prevention programs for WESW in Kazakhstan should consider multi-sectoral approaches that address economic hardship and relationship-based components, in addition to violence reduction.

A Systematic Review of Gender-Based Violence Prevention and Response Interventions for HIV Key Populations: Female Sex Workers, Men Who Have Sex With Men, and People Who Inject Drugs

Gender-based violence (GBV) is that perpetrated based on sex, gender identity, or perceived adherence to socially defined gender norms. This human rights violation is disproportionately experienced by HIV key populations including female sex workers (FSW), people who inject drugs (PWID), and men who have sex with men (MSM). Consequently, addressing GBV is a global priority in HIV response. There is limited consensus about optimal interventions and little known about effectiveness. Our systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered in International Prospective Register of Systematic Reviews. Peer-reviewed and non-peer-reviewed literature were searched for articles that described a GBV prevention or response intervention specifically for key populations including FSW, PWID, and MSM. Results were organized by level(s) of implementation and pillars of a comprehensive GBV response: prevention, survivor support, and accountability/justice. Of 4,287 articles following removal of duplicates, 32 unique interventions (21 FSW, seven PWID, and nine MSM, not mutually exclusive) met inclusion criteria, representing 13 countries. Multisectoral interventions blended empowerment, advocacy, and crisis response with reductions in violence. Individual-level interventions included violence screening and response services. Violence-related safety promotion and risk reduction counseling within HIV risk reduction programming reduced violence. Quantitative evaluations were limited. Violence prevention and response interventions for FSW, PWID, and MSM span individual, community, and multisectoral levels with evidence of promising practices at each level. The strongest evidence supported addressing violence in the context of sexually transmitted infection/HIV risk reduction. As interventions continue to emerge, the rigor of accompanying evaluations must simultaneously advance to enable clarity on the health and safety impact of GBV prevention and response programming.

Intertwined epidemics: progress, gaps, and opportunities to address intimate partner violence and HIV among key populations of women

The intersection of intimate partner violence and HIV is a public health problem, particularly among key populations of women, including female sex workers, women who use drugs, and transgender women, and adolescent girls and young women (aged 15-24 years). Intimate partner violence results in greater risk of HIV acquisition and creates barriers to HIV prevention, testing, treatment, and care for key populations of women. Socioecological models can be used to explain the unique multilevel mechanisms linking intimate partner violence and HIV. Few interventions, modelling studies, and economic evaluations that concurrently address both intimate partner violence and HIV exist, with no interventions tailored for transgender populations. Most combination interventions target individual-level risk factors, and rarely consider community or structural factors, or evaluate cost-efficacy. Addressing intimate partner violence is crucial to ending the HIV epidemic; this Review highlights the gaps and opportunities for future research to address the intertwined epidemics of intimate partner violence and HIV among key populations of women.

A cluster-randomized controlled trial of a combination HIV risk reduction and microfinance intervention for female sex workers who use drugs in Kazakhstan

INTRODUCTION

Female sex workers (FSW) who use drugs are a key population at risk of HIV in Kazakhstan, and face multiple structural barriers to HIV prevention. More research is needed on the role of structural interventions such as microfinance (MF) in reducing HIV risk. This paper describes the results of a cluster-randomized controlled trial to test the efficacy of a combination HIVRR + MF intervention in reducing biologically confirmed STIs and HIV risk behaviours.

METHODS

This study took place from May 2015 to October 2018 in two cities in Kazakhstan. We screened 763 participants for eligibility and enrolled 354 FSW who use drugs. Participants were randomized in cohorts to receive either a four-session HIVRR intervention, or that same intervention plus 30 additional sessions of financial literacy training, vocational training and asset-building through a matched-savings programme. Repeated behavioural and biological assessments were conducted at baseline, 3-, 6- and 12-months post-intervention. Biological and behavioural primary outcomes included HIV/STI incidence, sexual risk behaviours and drug use risk behaviours, evaluated over the 12-month period.

RESULTS

Over the 12-month follow-up period, few differences in study outcomes were noted between arms. There was only one newly-detected HIV case, and study arms did not significantly differ on any STI incidence. At post-intervention assessments compared to baseline, both HIVRR and HIVRR + MF participants significantly reduced sexual and drug use risk behaviours, and showed improvements in financial outcomes, condom use attitudes and self-efficacy, social support, and access to medical care. In addition, HIVRR + MF participants showed a 72% greater reduction in the number of unprotected sex acts with paying partners at the six-month assessment (IRR = IRR = 0.28, 95% CI = 0.08, 0.92), and a 10% greater reduction in the proportion of income from sex work at the three-month assessment (b = -0.10, 95% CI = -0.17, -0.02) than HIVRR participants did. HIVRR + MF participants also showed significantly improved performance on financial self-efficacy compared to HIVRR over the 12-month follow-up period.

CONCLUSIONS

Compared to a combination HIVRR + MF intervention, a robust HIVRR intervention alone may be sufficient to reduce sexual and drug risk behaviours among FSW who use drugs. There may be structural limitations to the promise of microfinance for HIV risk reduction among this population.

Microfinance and violence prevention: A review of the evidence and adaptations for implementation in the U.S

Microfinance programs provide access to small amounts of capital in the form of credit, savings, or financial incentives. There is evidence that microfinance reduces financial strain and reduces violence making it a promising public health approach. However, most of this evidence was generated internationally in low-resource countries; thus, it is likely that adaptations are necessary for microfinance to be effective at preventing violence in the U.S. This article reviews the evidence base for microfinance interventions on violence outcomes; outlines the potential of microfinance to prevent violence in the U.S.; and offers some possible adaptations in order to increase the likelihood that microfinance will prevent violence in the U.S. Programs might consider providing matched savings instead of small loans to individuals and providing job skills training. Furthermore, it is important for U.S. microfinance programs to engage multiple sectors and to consider additional content, such as a gender equity component and safety planning to protect those who might be in violent relationships. It is also important that these adaptations be rigorously evaluated for impacts on multiple forms of violence.

Women economic empowerment via cash transfer and microcredit programs is enough to decrease intimate partner violence? Evidence from a systematic review

Intimate partner violence (IPV) is a worldwide public health problem. Many proposals aiming to eliminate its occurrence include the empowerment of women through their socio-economic development. In this context, some studies suggested that microcredit programs (MP) and cash transfer programs (CTP) are initiatives that can also reduce the risk of IPV. Others pointed to an opposite effect. The objective of this study was to investigate the influence of women's economic empowerment in MP and CTP on the risk of physical, psychological and sexual violence through a systematic review. Papers/documents selection was conducted by two researchers according to the following criteria: published in English, Portuguese or Spanish; primary data; assessing the effect of MP or CTP on IPV; in heterosexual couples; on women beneficiaries of the intervention; using a comparator group eligible for an MP or CTP; and focusing on risk IPV as the outcomes. Our results showed that the impact of MP are mixed when it comes to physical and physical/sexual violence. Even so, the review suggests that the effect of MP on sexual violence is trivial or nonexistent. Regarding the impact of CTPs, the present study showed that the effects on physical, physical/sexual, psychological, and sexual violence were also heterogeneous. Women more empowered and with some autonomy could be at risk. Despite that, participation in the empowerment program should be encouraged for poor women and families. However, parallel interventions to lead with IPV should be addressed to the main actions to reduce the risk of increasing IPV prevalence in certain scenarios.

Microenterprise intervention to reduce sexual risk behaviors and increase employment and HIV preventive practices in economically-vulnerable African-American young adults (EMERGE): protocol for a feasibility randomized clinical trial

Background

Economic vulnerability, such as homelessness and unemployment, contributes to the HIV risk among racial minorities in the U.S., who are disproportionately infected. Yet, few economic-strengthening interventions have been adapted for HIV prevention in economically-vulnerable African-American young adults. Engaging Microenterprise for Resource Generation and Health Empowerment (EMERGE) is a feasibility randomized clinical trial of an HIV prevention microenterprise intervention with integrated text messages (“nudges”) that are informed by behavioral economic principles. The trial aims to reduce sexual risk behaviors and increase employment and uptake of HIV preventive behaviors.

Methods/design

In total, 40 young adults who are African-American, aged 18–24, live in Baltimore City, have experienced at least one episode of homelessness in the last 12 months, are unemployed or underemployed (fewer than 10 h per week), are not enrolled in school, own a cell phone with text messaging, and report at least one episode of unprotected or unsafe sex in the prior 12 months will be recruited from two community-based organizations providing residential supportive services to urban youth. Participants will undergo a 3-week run-in period and thereafter be randomly assigned to one of two groups with active interventions for 20 weeks. The first group (“comparison”) will receive text messages with information on job openings. The second group (“experimental”) will receive text messages with information on job openings plus information on HIV prevention and business educational sessions, a mentored apprenticeship, and a start-up grant, and business and HIV prevention text messages based on principles from behavioral economics. The two primary outcomes relate to the feasibility of conducting a larger trial. Secondary outcomes relate to employment, sexual risk behaviors, and HIV preventive practices. All participants will be assessed using an in-person questionnaire at pre-intervention (prior to randomization) and at 3 weeks post-intervention. To obtain repeated, longitudinal measures, participants will be assessed weekly using text message surveys from pre-intervention up to 3 weeks post-intervention.

Discussion

This study will be one of the first U.S.-based feasibility randomized clinical trials of an HIV prevention microenterprise intervention for economically-vulnerable African-American young adults. The findings will inform whether and how to conduct a larger efficacy trial for HIV risk reduction in this population.

Economic Policies and Intimate Partner Violence Prevention: Emerging Complexities in the Literature

Although the question of whether economic policies serve to reduce rates of intimate partner violence (IPV) has long been raised, rigorous tests of this question have only begun to take place recently. Given the mixed evidence to date, much remains unknown about the circumstances in which a positive or negative relationship holds between changes in financial well-being and IPV. We describe an empirically based theoretical model that may link economic empowerment to IPV and that highlights research questions for further testing. This model reflects two theoretical pathways through which economic policies may reduce IPV: A program may activate social and psychological empowerment as protective factors and a program may deactivate cognitive and behavioral risk factors such as stress and substance abuse. We then consider the relevance of each of a range of economic policies and review existing experimental evidence regarding the effect of such programs on IPV. We discuss unconditional and conditional cash transfers, savings programs, microfinance and income generation programs, and economic programs combined with relationship-related training. Gaps in research on this topic and emerging complexities in the literature suggest the following three key areas that would benefit from greater research and evaluation: comparison across programs based on size and design, assessment of the returns to economic empowerment of young adults, and more evaluations in high-income countries.

The impact of violence, perceived stigma, and other work-related stressors on depressive symptoms among women engaged in sex work

While the physical health risks of sex work have been well documented, fewer studies have explored mental health risks associated with sex work. This study examined rates of depressive symptoms and associated risk factors among women engaged in sex work in Mongolia (n=222), a country experiencing significant economic and social development and where mental health infrastructure is in its infancy. A linear regression analysis indicated that significant risk factors for depressive symptoms included paying partner sexual violence, perceived occupational stigma, less social support, and higher harmful alcohol use. As one of the first studies to examine depression among sex workers, this study holds important social welfare implications for this marginalized population in Mongolia and other low-resource settings globally.
