HIV self-testing and oral pre-exposure prophylaxis are empowering for sex workers and their intimate partners: a qualitative study in Uganda. J Int AIDS Soc 2021; 24:e25782.

Abstract
Introduction HIV self‐testing (HIVST) and oral pre‐exposure prophylaxis (PrEP) are complementary, evidence‐based, self‐controlled HIV prevention tools that may be particularly appealing to sex workers. Understanding how HIVST and PrEP are perceived and used by sex workers and their intimate partners could inform prevention delivery for this population. We conducted qualitative interviews to examine ways in which HIVST and PrEP use influence prevention choices among sex workers in Uganda. Methods Within a randomized trial of HIVST and PrEP among 110 HIV‐negative cisgender women, cisgender men and transgender women sex workers (NCT03426670), we conducted 40 qualitative interviews with 30 sex workers and 10 intimate partners (June 2018 to January 2020). Sex worker interviews explored (a) experiences of using HIVST kits; (b) how HIVST was performed with sexual partners; (c) impact of HIVST on PrEP pill taking; and (d) sexual risk behaviours after HIVST. Partner interviews covered (i) introduction of HIVST; (ii) experiences of using HIVST; (iii) HIV status disclosure; and (iv) HIVST's effect on sexual behaviours. Data were analysed using an inductive content analytic approach centering on descriptive category development. Together, these categories detail the meaning of HIVST and PrEP for these qualitative participants. Results Using HIVST and PrEP was empowering for this group of sex workers and their partners. Three types of empowerment were observed: (a) economic; (b) relational; and (c) sexual health. (i) Using HIVST and PrEP made sex without condoms safer. Sex workers could charge more for condomless sex, which was empowering economically. (ii) Self‐testing restored trust in partners’ fidelity upon being reunited after a separation. This trust, in combination with condomless sex made possible by PrEP use, restored intimacy, empowering partnered relationships. (iii) HIVST and PrEP enabled sex workers to take control of their HIV prevention efforts and avoid the stigma of public clinic visits. In this way they were empowered to protect their sexual health. Conclusions In this sample, sex workers’ use of HIVST and PrEP benefitted not only prevention efforts, but also economic and relational empowerment. Understanding these larger benefits and communicating them to stakeholders could strengthen uptake and use of combination prevention interventions in this marginalized population.

Abstract
Mobility among sex workers has been linked not only to improved economic and social opportunities, but also to concerns regarding displacement, criminalization, and violence. In 2014, new "end-demand" legislation criminalized new aspects of sex work in Canada (e.g., third-party advertising, purchasing) while leaving the sale of sex legal. Utilizing data from a longitudinal community-based cohort of women sex workers in Metro Vancouver (An Evaluation of Sex Workers Health Access [AESHA], 2010-2016), we used kernel density mapping to understand and identify geographic patterns of workplace neighborhood mobility (i.e., changing the primary neighborhood in which one worked in the last 6 months); multivariable logistic regression using generalized estimating equations was also used to model contextual (policing, violence, and safety) and individual correlates of workplace mobility among sex workers over the 6-year period, including potential changes in mobility patterns pre- and post-end-demand criminalization. A total of 543 sex workers were included in analyses, contributing 2,199 observations. A total of 402 (74.0%) experienced workplace neighborhood mobility during the study period. Neighborhood mobility was negatively correlated with age (adjusted odds ratio [AOR] = 0.98/year older, 95% confidence interval [CI] = [0.97, 0.99]) and positively correlated with homelessness (AOR = 1.43, 95% CI = [1.12, 1.82]), identifying as a gender/sexual minority (AOR = 1.31, 95% CI = [1.04, 1.70]), and servicing clients primarily outdoors (vs. informal indoor or in-call venues; AOR = 1.48, 95% CI = [1.21, 1.81]); police harassment (AOR = 1.19, 95% CI = [0.96, 1.48], p = .11) and changing one's neighborhood of work due to safety concerns (AOR = 1.37, 95% CI = [0.94, 2.00], p = .09) were both marginally correlated. Steps to promote safer working conditions for marginalized women in urban environments remain urgently needed, including shifts away from criminalized enforcement toward community-led initiatives and promoting access to safer indoor workspaces.

Abstract
The aim of this study was to estimate the prevalence of depression among female sex workers (FSW) in an urban coastal city in South Africa, and to explore the relationship between depression and HIV-related social and biobehavioral determinants. A cross-sectional respondent-driven sampling study was conducted with FSW (n = 410), including a sociobehavioral questionnaire, PHQ-9 (Patient Health Questionnaire-9) based assessment of depression, and biological testing for HIV and syphilis. The prevalence of HIV in the sample was 64.1%. The estimated prevalence of depression was 28.8%. Depression was associated with social vulnerability such as living alone [adjusted prevalence ratio 1.82, 95% confidence interval (CI) 1.15-2.90] and food insecurity (aPR 2.19, 95% CI 1.42-3.38). A positive syphilis test result (aPR 1.46, 95% CI 1.02-2.09) and self-reported sexually transmitted disease symptoms (aPR 1.78, 95% CI 1.29-2.46) was associated with depression, but self-reported condom use and HIV status was not. FSW were also less likely to disclose their occupational status to health care providers (aPR 0.61, 95% CI 0.42-0.89) or undergo sexually transmitted infection screening in the last 12 months if they are depressed (aPR 0.64, 95% CI 0.43-0.95). The results demonstrate that the prevalence of depression is high among FSW and that depressive symptoms are associated with social covariates and biobehavioral HIV risk factors.

Abstract
Violence against women is a known risk factor for HIV and affects female sex workers (FSW) in sub-Saharan Africa. Little is known about the magnitude and determinants of violence against FSW in Zambia, where HIV and gender-based violence prevalence are high. We conducted a cross-sectional study, using multivariable logistic regression, to determine the prevalence and correlates of client-initiated physical violence among 419 FSW in Lusaka and Ndola. The prevalence of client-initiated physical violence was 39%. The odds of violence were higher for FSW who: lived in Lusaka, recruited clients from the street, serviced clients in the clients' homes, had a physically forced sexual debut, and had a higher client volume. Our results call for safer working spaces for FSW and violence prevention interventions for their male clients.

Abstract
We examined the relationship between mindfulness, mental health and HIV outcomes among female sex workers (FSW) from the Dominican Republic (DR) (n = 201) and Tanzania (n = 208) using cross-sectional survey and biologic data. We employed stratified multivariate linear and logistic regression. Depression was associated with lower odds of ART adherence in the DR (AOR 0.25, 95% CI: 0.08-0.78) and of viral suppression in Tanzania (AOR 0.49, 95% CI: 0.24-0.97). In both countries, mindfulness was associated with lower odds of moderate to severe depression (AOR 0.82, 95% CI: 0.76-0.88 for the DR; AOR 0.85, 95% CI: 0.77-0.95 for Tanzania). In the DR, mindfulness was associated with lower odds of anxiety (AOR 0.83, 95% CI: 0.77-0.89), lower HIV stigma (β = - 0.28 per unit change, 95% CI: - 0.37 to - 0.19) and greater odds of viral suppression (AOR 1.09, 95% CI: 1.02-1.15). Findings demonstrate the potential of tailored mindfulness interventions to improve mental health and HIV outcomes among FSW.

Abstract
BACKGROUND Female sex workers (FSWs) have elevated rates of sexually transmitted infections (STIs) including HIV, yet few studies in the United States have characterized the STI burden in this population. METHODS Data were derived from the EMERALD study, a structural community-based intervention with FSWs in Baltimore, MD. Participants (n = 385) were recruited through targeted sampling on a mobile van. Prevalent positive chlamydia or gonorrhea infections were determined by biological samples. Multivariable logistic regressions modeled correlates of confirmed positive STI (gonorrhea or chlamydia). RESULTS Confirmed STI positive prevalence was 28%, 15% chlamydia and 18% gonorrhea. Approximately two-thirds of the sample (64%) was younger than 40 years, one-third (36%) were Black, and 10% entered sex work in the past year. The sample was characterized by high levels of structural vulnerabilities (e.g., housing instability and food insecurity) and illicit substance use. Female sex workers were more likely to have a positive STI if they had financial dependent(s) (P = 0.04), experienced food insecurity at least weekly (P = 0.01), entered sex work in the past year (P = 0.002), and had 6 or more clients in the past week (P = 0.01). Female sex workers were less likely to have a positive STI test result if they were 40 years or older compared with FSW 18 to 29 years old (P = 0.02), and marginally (P = 0.08) less likely with high (vs. low) social cohesion. CONCLUSIONS More than a quarter of FSWs had confirmed chlamydia or gonorrhea. In addition to STI risks at the individual level, STIs are driven by structural vulnerabilities. Results point to a number of salient factors to be targeted in STI prevention among FSWs.

Abstract
After Canada's laws criminalising sex work were struck down by the Supreme Court for violating sex workers' rights and new end-demand legislation was passed in 2014. These new laws however continue to criminalise sex work third parties (i.e. venue owners/managers) who gain material benefits, despite evidence that managed in-call venues can provide important protections for sex workers. As part of a longstanding community-based study in Vancouver, this analysis drew on 25 in-depth interviews with third parties who provide services for indoor sex workers. We explored how end-demand third party criminalisation shapes indoor sex workers' working conditions, health and safety. We found that most third parties were women and current/former sex workers, problematising assumptions of third parties as exploitative male "pimps". Third parties provided client screening, security and sexual health resources for sex workers, yet end-demand laws restricted condom availability and access to police protections in case of violence, thereby undermining sex workers' health and safety. Our findings highlight that third party criminalisation under end-demand legislation reproduces the unsafe working conditions under the previous laws deemed unconstitutional by Canada's highest court. Legislative reforms to decriminalise all aspects of the sex industry, including sex workers' right to work with third parties, are urgently needed.

Abstract
We examine the typologies of workplaces for sex workers in Dnipro, Ukraine as part of the larger Dynamics Study, which explores the influence of conflict on sex work. We conducted a cross-sectional survey with 560 women from September 2017 to October 2018. The results of our study demonstrate a diverse sex work environment with heterogeneity across workplace typologies in terms of remuneration, workload, and safety. Women working in higher prestige typologies earned a higher hourly wage, however client volume also varied which resulted in comparable monthly earnings from sex work across almost all workplace types. While sex workers in Dnipro earn a higher monthly wage than the city mean, they also report experiencing high rates of violence and a lack of personal safety at work. Sex workers in all workplaces, with the exception of those working in art clubs, experienced physical and sexual violence perpetrated by law enforcement officers and sex partners. By understanding more about sex work workplaces, programmes may be better tailored to meet the needs of sex workers and respond to changing work environments due to ongoing conflict and COVID-19 pandemic.

Abstract
How do choices in criminal law and rights protections affect disease-fighting efforts? This long-standing question facing governments around the world is acute in the context of pandemics like HIV and COVID-19. The Global AIDS Strategy of the last 5 years sought to prevent mortality and HIV transmission in part through ensuring people living with HIV (PLHIV) knew their HIV status and could suppress the HIV virus through antiretroviral treatment. This article presents a cross-national ecological analysis of the relative success of national AIDS responses under this strategy, where laws were characterised by more or less criminalisation and with varying rights protections. In countries where same-sex sexual acts were criminalised, the portion of PLHIV who knew their HIV status was 11% lower and viral suppression levels 8% lower. Sex work criminalisation was associated with 10% lower knowledge of status and 6% lower viral suppression. Drug use criminalisation was associated with 14% lower levels of both. Criminalising all three of these areas was associated with approximately 18%-24% worse outcomes. Meanwhile, national laws on non-discrimination, independent human rights institutions and gender-based violence were associated with significantly higher knowledge of HIV status and higher viral suppression among PLHIV. Since most countries did not achieve 2020 HIV goals, this ecological evidence suggests that law reform may be an important tool in speeding momentum to halt the pandemic.

Female sex workers (FSW) are a key population in the HIV epidemic and face high levels of violence. While women globally are predominantly at risk of intimate partner violence (IPV), FSW are additionally vulnerable to violence from clients, police, and pimps associated with their occupation. FSW are therefore at risk of cumulative trauma from polyvictimization, or violence from multiple types of perpetrators. Polyvictimization is a driver of morbidity and mortality in numerous populations, but there has been little research on how multiple types of victimization are related to one another in FSW. A cross-sectional survey was conducted among 754 FSW from three cities in the Russian Federation. Surveys assessed lifetime experiences of client, police, intimate partner, and pimp violence. Multivariate log-binomial and Poisson regression were used to test associations between these types of violence. Forty-five percent experienced any type of violence, including 31.7% from clients, 16.0% from police, 15.7% from intimate partners, and 11.4% from pimps. One fifth (20.4%) experienced polyvictimization. Client violence was central to polyvictimization: Only 5.9% of polyvictimization occurs without client violence. When client violence was not present, police, pimp, or IPV co-occurred significantly less than would be expected under an assumption that these types of violence occur independently (p < .001). However, they co-occurred more than would be expected when client violence is present. After adjusting for other types of violence experienced and demographic factors, experiencing client violence was independently associated with police violence (adjusted relative risk [ARR] = 2.77, 95% confidence interval [CI] [1.67, 4.59]), IPV (ARR = 3.67, 95% CI [1.95, 6.89]), and pimp violence (ARR = 5.26, 95% CI [2.80, 9.86]). Client violence may drive exposure to other types of violence and enable polyvictimization in a way that other types of violence do not in this setting. Violence prevention interventions may achieve maximal effect in reducing multiple types of violence by focusing on client violence.

Abstract
This commentary explores the missing discourse of sexual rights and sexual pleasure in the Sustainable Development Goals (SDG) that purport to leave no one behind. The SDG propose a welcome focus on sexual health and human rights for all, expanding beyond the Millennium Development Goals. While promising in many ways for advancing global sexual and reproductive health, and reproductive rights, the omission of sexual rights is troubling. So too is the erasure of lesbian, gay, bisexual, transgender and queer (LGBTQ) persons, and sex workers, from the SDG discussions of social inequities. Illustrative examples are provided to demonstrate how a sexual rights focus could advance SDG 3 focused on healthy lives and well-being for all. First, sexual rights are presented as integral to realizing Target 3.3's focus on ending the HIV pandemic among LGBTQ persons and sex workers (and LGBTQ sex workers). Second, sexual pleasure is introduced as an integral component of sexual health and sexual rights that could facilitate the realization of Target 3.7's aim to provide universal access to sexual and reproductive health information and education. To truly leave no one behind and realize sexual health for all, the SDG need to begin from a foundation of sexual rights.

Abstract
OBJECTIVE Given stark health inequities among precarious and criminalized workers, we aimed to apply a structural determinants framework to systematically review evidence on HIV/sexually transmitted infection (STI) prevalence, access to HIV/STI/SRH services, and condom use among im/migrant sex workers (ISWs) globally. METHODS Systematic search of peer-reviewed studies published in English (2009-2019). Eligible studies reported HIV/STI, access to HIV/STI/SRH services, and/or condom use outcomes and/or lived experiences among ISWs. Quantitative and qualitative data were synthesized using a structural determinants framework. RESULTS Of 425 studies screened, 29 studies from 15 countries were included. HIV prevalence ranged from 0.3 to 13.6% and varied across settings, with highest prevalence among undocumented ISWs in a high-income country (Portugal). Precarious immigration status was a structural factor associated with poorer HIV/STI outcomes, whereas qualitative narratives showed ISWs' lived experiences as strongly shaped by policing and stigma. Despite disparities, in some settings, HIV and STI prevalence were lower and odds of condom use with clients were higher among ISWs relative to non-im/migrant sex workers. This review identified a paucity of research on SRH and male and gender-diverse ISWs. Across legislative settings, criminalization of SW and im/migrant status, policing, and migration-related marginalization were prominent structural barriers to ISWs' HIV/STI/SRH access. CONCLUSION This review identified important inequities and variation in HIV/STI prevalence among ISWs globally. Our findings highlight impacts of the intersections of migration and criminalization, and suggest a need to reform criminalized sex work laws; address punitive policing and immigration enforcement; enable safer indoor work environments; and expand community-based interventions towards promoting HIV/STI/SRH access and health equity among ISWs.

Abstract
INTRODUCTION Despite extraordinary progress in HIV treatment coverage and expanding access to HIV prevention services and that multiple African countries are on track in their efforts to reach 90-90-90 goals, the epidemic continues to persist, with prevalence and incidence rates too high in some parts of the continent to achieve epidemic control. While data sources are improving, and research studies on key populations in specific contexts have improved, work on understanding the HIV burdens and barriers to services for these populations remains sparse, uneven and absent altogether in multiple settings. More data have become available in the last several years, and data published in 2010 or more recently are reviewed here for each key population. This scoping review assesses the current epidemiology of HIV among key populations in Africa and the social and political environments that contribute to the epidemic, both of which suggest that without significant policy reform, these epidemics will likely continue. RESULTS AND DISCUSSION Across Africa, the HIV epidemic is most severe among key populations including women and men who sell or trade sex, men who have sex with men, people who inject drugs, transgender women who have sex with men and prisoners and detainees. These groups account for the majority of new infections in West and Central Africa, and an estimated 25% of new infections in East and Southern Africa, despite representing relatively small proportions of those populations. The HIV literature in Africa emphasizes that despite significant health needs, key populations experience barriers to accessing services within the healthcare and legal justice systems. Current shortcomings of surveillance systems in enumerating key populations impact the way funding mechanisms and resources are allocated and distributed. Adapting more equitable and epidemiologically sound frameworks will be necessary for current and future HIV programming investments. CONCLUSIONS Through this review, the available literature on HIV epidemiology among key populations in Africa brings to light a number of surveillance, programmatic and research gaps. For many communities, interventions targeting the health and security conditions continue to be minimal. Compelling evidence suggests that sweeping policy and programmatic changes are needed to effectively tackle the persistent HIV epidemic in Africa.

"Feeling Safe, Feeling Seen, Feeling Free": Combating stigma and creating culturally safe care for sex workers in Chicago. PLoS One 2021; 16:e0253749. [PMID: 34185795 PMCID: PMC8241054 DOI: 10.1371/journal.pone.0253749] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Accepted: 06/12/2021] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Previous studies have established that sex workers experience discrimination and stigma within healthcare settings, limiting their access and receipt of culturally safe care. These barriers impact sex workers' ability and desire to routinely engage with the healthcare system. Community empowerment interventions that are culturally safe offer an effective strategy to improve access to services and health outcomes for sex workers. OBJECTIVES This project was designed to inform the development of community empowerment interventions for sex workers by understanding their self-management, health promotion, and harm reduction needs. METHODS In-depth interviews (N = 21) were conducted with sex workers in Chicago. Transcripts of individual interviews were analyzed in Dedoose using rapid content analysis. RESULTS Participants had a mean age of 32.7 years; 45% identified as White, 20% as Black, 15% as Latinx, and 20% as multiple races; 80% identified as Queer. A total of 52% of participants identified as cisgender women, 33% as transgender or gender fluid, 10% as cisgender men, and 5% declined to answer. Themes of self-management practices, stigmatizing and culturally unsafe experiences with healthcare providers, and the prohibitive cost of healthcare emerged as consistent barriers to routinely accessing healthcare. Despite identifying patient-centered care as a desired healthcare model, many participants did not report receiving care that was respectful or culturally responsive. Themes also included developing strategies to identify sex worker-safe care providers, creating false self-narratives and health histories in order to safely access care, and creating self-care routines that serve as alternatives to primary care. CONCLUSION Our findings demonstrate how patient-centered care for sex-workers in Chicago might include holistic wellness exercises, accessible pay scales for services, and destigmatizing healthcare praxis. Focus on culturally safe healthcare provision presents needs beyond individualized, or even community-level, interventions. Ongoing provider training and inbuilt, systemic responsivity to patient needs and contexts is crucial to patient-centered care.

Abstract
INTRODUCTION UNAIDS has identified female sex workers (FSW) as a key HIV at-risk population. FSW disproportionately experience gender-based violence, which compounds their risk of HIV acquisition and may contribute to adverse mental health outcomes. Pre-exposure prophylaxis (PrEP) is a powerful but underused HIV prevention tool for these women. This study explored the associations between intimate partner violence (IPV) and client-perpetrated violence against FSW, mental health outcomes and PrEP use. METHODS An anonymous questionnaire was administered to a convenience sample of 220 Nairobi FSW attending dedicated clinics from June to July 2019, where PrEP was available free of charge. A modified version of the WHO Violence Against Women Instrument assessed IPV and client-perpetrated violence, and the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) assessed depressive and anxiety symptoms respectively. Multivariable logistic regressions evaluated predictors of depression, generalized anxiety and PrEP use. RESULTS Of the total 220 women (median [IQR] age 32 [27-39]), 56.8% (125/220) reported depression (PHQ-9 ≥ 10) and 39.1% (86/220) reported anxiety (GAD-7 ≥ 10). Only 41.4% (91/220) reported optimal use of PrEP (taken correctly six to seven days/week) despite the cohort pursuing sex work for a median of 7 (4 to 12) years. Most women reported experiencing any violence in the past 12 months (90%, 198/220). Any recent IPV was frequent (78.7%, 129/164), particularly emotional IPV (66.5%, 109/164), as was any client-perpetrated violence in the past 12 months (80.9%, 178/220). Regression analyses found that violence was independently associated with depression (adjusted OR [aOR] 9.39, 95% CI 2.90 to 30.42, p = 0.0002) and generalized anxiety (aOR 3.47, 95% CI 1.10 to 10.88, p = 0.03), with the strongest associations between emotional IPV and both depression and anxiety. Recent client-perpetrated emotional violence (aOR 0.23, 95% CI 0.07 to 0.71, p = 0.01) was associated with decreased PrEP use, whereas client-perpetrated physical violence was associated with increased PrEP use (aOR 3.01, 95% CI 1.16 to 7.81, p = 0.02). CONCLUSIONS There was a high prevalence of recent violence by different perpetrators as well as depression and anxiety among FSW from Nairobi. PrEP use was relatively infrequent, and recent client-perpetrated emotional violence was associated with PrEP non-use. Interventions to reduce gender-based violence may independently enhance HIV prevention and reduce the mental health burden in this community.

Seroprevalence and Associated Factors of Human Immunodeficiency Virus, Treponema pallidum, Hepatitis B Virus, and Hepatitis C Virus among Female Sex Workers in Dessie City, Northeast Ethiopia. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6650333. [PMID: 34124256 PMCID: PMC8172302 DOI: 10.1155/2021/6650333] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Accepted: 05/18/2021] [Indexed: 12/25/2022]
Abstract
Introduction Sexually transmitted infections (STIs) are prevalent in Ethiopia and elsewhere among different population groups particularly among female sex workers (FSWs). Because of their work and their behavior, FSWs are at high risk to acquire STIs. The aim of the study was to assess the seroprevalence and associated factors of HIV, HBV, HCV, and T. pallidum among FSWs in Dessie City, Northeast Ethiopia. Methods This cross-sectional study was conducted in Dessie City, Amhara Region, Northeastern Ethiopia, from November 2017 to April 2018. A total of 360 FSWs whose age is greater than or equal to 18 years and who are willing to participate were recruited by simple random sampling technique. Interview-based questionnaire was administered, and 5 ml of venous blood from each participant was drawn under aseptic conditions. The rapid test was performed to obtain the result of the four STIs (HIV, T. pallidum, HBV, and HCV). The collected data were entered and analyzed by SPSS version 20.0. From the bivariable analysis, variables having P value < 0.2 were retained into multivariable analysis. From the multivariable analysis, variables with P value < 0.05 were affirmed as statistically associated factors. Adjusted odds ratios and their 95% confidence intervals were used as indicators of the strength of association. Results Majority of study participants were urban dwellers, 10 (2.8%) respondents were married, 61 (16.9%) have more than two children, and more than half of them were at the age range between 18 and 27 years. Any infection with STIs was 84 (23.3%), whereas 27 (7.5%), 47 (13.1%), 2 (0.6%), and 45 (12.5%) study participants were positive for laboratory test of HIV, HBV, HCV, and T. pallidum, respectively. Marital status, sharing of sharp materials, breakage of condom, number of customers per week, genital discharge, and pain had significant association with any STI. Conclusions In comparison with different research works in Ethiopia and abroad, the prevalence of any STI, HIV, HBV, and T. pallidum was found to be relatively high. Preventive approach and appropriate treatment of STIs should be developed. Concerned body should work together to alleviate the problem by counseling and recruiting them on other productive job sectors in the country.

Abstract
BACKGROUND In the United States, the criminalization and stigmatization of drug use and sex work contribute to infectious disease transmission and healthcare disengagement. People who inject drugs (PWID) and engage in sex work experience exacerbated HIV risk. In the context of the ongoing HIV and overdose epidemics little research describes why PWID engage in sex work and its relative HIV risk. To inform intervention needs, we aimed to create a typology of sex work among PWID with a focus on HIV risk and healthcare utilization behaviours. METHODS We drew from in-depth interviews conducted across Massachusetts and Rhode Island from 2016-2019. Participants were ≥18 years old and self-reported past-month injection drug use and HIV-negative status. Using data from individuals reporting sex work experience (n=33/78), we utilized the framework method to develop a typology of perspectives on sex work engagement and attributes pertaining to HIV risk and healthcare utilization behaviours. RESULTS We uncovered varying perspectives on sex work and associated HIV risks and prevention needs. A typology included three groups who viewed their sex work engagement as a (1) consistent job, (2) income supplement, or (3) survival method to abate withdrawal symptoms. The first group described more consistent sexual and injection behaviours to mitigate HIV risk than the second group. The third group appeared particularly vulnerable to HIV, describing inconsistent condom use and frequent sharing of injection equipment, low healthcare utilization, and limited disclosure of sex work and injection drug use to healthcare providers. CONCLUSION Findings highlight distinct perspectives on sex work among PWID involved in it and corresponding perceptions of HIV risk and healthcare utilization behaviours. Understanding the nuances in sex work engagement among PWID can inform interventions to prevent infectious disease transmission, including efforts to further connect this marginalized population to harm reduction, health, and low barrier opioid treatment services.

Abstract
OBJECTIVES Though highly vulnerable to HIV and STIs, transgender female sex workers (TFSWs) are understudied in the US HIV and STI response. This study examined the correlates of laboratory-confirmed STIs among a cohort of 62 TFSWs followed over the course of 1 year and explored associations between specimen site and self-reported engagement in insertive and receptive anal intercourse. METHODS Participants completed an interviewer-administered computer-assisted personal interview at baseline, 3-, 6-, 9- and 12-month visits where self-administered anal swabs and urine samples for gonorrhea, chlamydia and trichomoniasis were also collected. HIV testing was conducted at baseline, 6-month and 12-month visits. RESULTS Baseline HIV prevalence was 40.3% with no HIV seroconversions over follow-up. Baseline prevalence of gonorrhea, chlamydia and trichomoniasis was 9.7%, 17.7% and 14.5%, respectively. In the multivariable regression modelling, recent arrest was significantly associated with testing positive for any STI (adjusted risk ratio (RR) 1.77; 95% CI: 1.10 to 2.84). Insertive anal sex with clients was associated with increased risk of testing positive for an STI via urine specimen (RR 3.48; 95% CI: 1.14 to 10.62), while receptive anal sex was not significantly associated with specimen site. CONCLUSION Our findings confirm a high prevalence of STIs among TFSWs and highlight the importance of addressing structural drivers such as criminal justice involvement as well as the need to ensure screening for STIs at all anatomical sites regardless of self-reported sites of potential exposure. More research is needed to better understand HIV and STI vulnerabilities and appropriate interventions for TFSWs in the USA.

Abstract
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.

Prevalence and Factors Associated With HIV and Sexually Transmitted Infections Among Female Sex Workers in Bamako, Mali. Sex Transm Dis 2021; 47:679-685. [PMID: 32932403 DOI: 10.1097/olq.0000000000001231] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND We aimed to (1) estimate the prevalence of HIV and other sexually transmitted infections (STIs) among female sex workers (FSWs) in Bamako, Mali, and (2) identify factors associated with STIs including HIV infection in this population. METHODS We analyzed baseline data from a prospective observational cohort study on cervical cancer screening, human papillomavirus, and HIV infections among FSWs 18 years or older recruited in Bamako. Multivariable log-binomial regression was used to estimate the adjusted prevalence ratios (APRs) with 95% confidence interval (95% CI) for HIV infection and STIs versus associated factors. RESULTS Among 353 women participating in the study, mean age was 26.8 (±7.6) years. HIV prevalence was 20.4%, whereas 35.1% of the FSWs had at least one STI. Factors significantly associated with HIV were older age (P < 0.0001, test for trend), duration of sex work ≥6 years (APR, 1.92; 95% CI, 1.22-3.02), uneducated status (APR, 2.24; 95% CI, 1.16-4.34), less than 10 clients in the last 7 days (APR, 1.55; 95% CI, 1.02-2.34), and gonococcal (APR, 1.85; 95% CI, 1.21-2.82) and chlamydial (APR, 2.58; 95% CI, 1.44-4.62) infections. Younger age (P = 0.018, test for trend), having ≥10 clients in the last week (APR, 1.47; 95% CI, 1.11-1.94), and HIV infection (APR, 2.00; 95% CI, 1.49-2.69) were significantly associated with STIs. CONCLUSIONS HIV and curable STI prevalence are high among FSWs in Bamako. There is thus a need to enhance the efficiency of interventions toward FSWs in Mali to reduce the burden of HIV and STIs among them and prevent HIV spread to the general population.

Abstract
The provision of comprehensive prevention services is vital for reducing the high burden of HIV amongst Ukrainian female sex workers (FSWs). To identify barriers and facilitators that influence access to HIV prevention amongst this population between 2009 and 2017, we developed a literature-informed conceptual framework and conducted a document analysis to identify the components of the Ukrainian prevention package (PP). Using the Integrated Bio Behavioural Surveillance Surveys, we then conducted descriptive analyses to explore PP coverage from 2009 to 2017 and the influence of factors, identified by our conceptual framework. After increasing over four years, a drop in PP coverage was observed from 2013 onwards. Being a client of a non-governmental organisation, street and highway solicitation, non-condom use, and knowledge of HIV may influence access to HIV prevention in the Ukrainian context. Future interventions should consider barriers and facilitators to HIV prevention and the multiple structural levels on which they operate.

Abstract
There is significant debate regarding the regulation of the sex industry, with a complex range of cultural, political and social factors influencing regulatory models which vary considerably between and within countries. This systematic review examined the available evidence on the relationship between different approaches to sex industry regulation in high-income countries, and associated effects on sex worker health status. Objectives included identification of sex worker health outcomes, including sexual health, substance use and experience of stigma and violence. A search was performed electronically in eight scholarly databases which yielded 95 articles which met the criteria for inclusion. Findings suggested that sex workers in legalised and decriminalized countries demonstrated greater health outcomes, including awareness of health conditions and risk factors.

Abstract
This paper examines the prevalence of and potential for community mobilization (CM) and its association with HIV/STI risk, substance use, and violence victimization among women, particularly those using substances, in the sex trade in Tijuana, Mexico. METHODS 195 women participated in Mujeres Unidas (K01DA036439 Urada) under a longitudinal survey study, "Proyecto Mapa de Salud" (R01DA028692, PI: Brouwer). Local health/social service providers (N = 16) were also interviewed. RESULTS 39% of women who participated in community mobilization activities used substances. In adjusted analyses (n = 135), participation in CM activities (n = 26) was more likely among women who did not report substance use (AOR: 4.36, CI: 1.11-17.16), perceived a right to a life free from violence (AOR: 9.28, CI: 2.03-59.26), talked/worked with peers in the sex trade to change a situation (AOR: 7.87, CI: 2.03-30.57), witnessed violence where they worked (AOR: 4.45, CI: 1.24-15.96), and accessed free condoms (AOR: 1.54, CI: 1.01-2.35). Forty-five of the women using substances demonstrated their potential for engaging in asset-based community development (ABCD) with service providers in Mujeres Unidas meetings. CONCLUSION Women using substances, vs. those who did not, demonstrated their potential to engage in ABCD strategies. Women's empowerment, safety, and health could be enhanced by communities engaging in ABCD strategies that build and bridge social capital for marginalized women who otherwise have few exit and recovery options.

Abstract
Past studies that have designed interventions to reduce the prevalence of sexually transmitted infections (STIs) have typically provided onsite treatment to sex workers who tested positive, which were expensive and difficult to implement. The purpose of this study was to examine the effect of an intervention which tested for STIs and provided information on the closest treatment facility on reducing the prevalence of STIs among female brothel-based sex workers (BSWs) in Bangladesh. The study adopted a pre-post interventional design as well as a randomized controlled study design. A baseline sample and follow-up urine sample were collected to evaluate the prevalence of STIs among participants in the treatment, but not control group. A baseline survey and interviews were also conducted for both the groups. The study found a nonsignificant reduction from baseline to follow-up in STI prevalence among intervention participants (adjusted odds ratio [aOR]: 0.74; 95% CI: 0.38, 1.45). However, the participants in the intervention group were significantly more likely to have a repeat client (aOR: 1.60; 95% CI: 1.12, 2.29) and nonsignificantly less likely to engage with a client suspected of having an STI (aOR: 0.62; 95% CI: 0.39, 1.00) than participants in the control group. The intervention testing of STIs and providing information to the positive cases about nearest treatment facilities were not effective in reducing the prevalence of STIs among BSWs. Further study of the clinical and behavioral impacts of such efforts to reduce STIs among BSWs is warranted.

Abstract
The purpose of this study was to characterize the social networks of female sex workers (FSWs) living with HIV in the Dominican Republic (DR) and to examine the association between daily drug use and network risk profile. The study employed a micro-longitudinal observational design using a 7-day mobile health (mHealth) daily diary to collect daily substance use behaviors and social network data was collected at study enrollment. A series of crude and adjusted modified log-Poisson repeated measures regression models with generalized estimating equations (GEE), clustering by individual with a compound symmetry working correlation structure were fit to estimate the relative risks and 95% confidence intervals. Controlling for individual level factors, findings revealed that FSWs with more network members who were drug users (≥ 3) and more network members who were sexual partners and also drugs users (≥ 2) were 8.89 (95% CI 2.62, 30.22) and 6.08 (95% CI 1.20, 30.92) times more likely to engage in daily drug use compared to women with small drug and sex and drug networks. Study findings demonstrate the role high risk networks have on risk behaviors. Results may be used to inform interventions that focus on modifying negative social ties, creating and/or improving existing positive support relationships, and integrating drug use harm reduction promotion within HIV treatment programs.

Abstract
Globally, cisgender women sex workers (CWSWs) and transgender women sex workers (TWSWs) experience increased vulnerabilities to HIV infection. Unfortunately, there is limited data on the drivers of HIV infection in these two understudied populations, particularly in Southeast Asia. To better understand factors associated with HIV infection, we evaluated correlates of newly diagnosed HIV infection in these two populations in Greater Kuala Lumpur, Malaysia. A total of 469 women (CWSW: n = 283; TWSW: n = 186) were included in this study. Most participants who tested HIV+ were unaware of their infection (59.6%; n = 34/57). Separate binary and multivariable logistic regressions were conducted to identify correlates of newly diagnosed HIV in CWSWs and TWSWs. Among CWSWs, Chlamydia trachomatis (aOR = 5.66; p = 0.007) and lifetime use of ecstasy/MDMA (aOR = 5.34; p = 0.03) were associated with newly diagnosed HIV, while condomless vaginal sex with clients was associated with lower likelihood of HIV infection (aOR = 0.98; p = 0.01). Among TWSWs, being single (aOR = 6.76; p = 0.03), using mobile application to solicit clients (aOR = 25.33; p = 0.006), and having C. trachomatis infection (aOR = 88.22, p = 0.02) were associated with newly diagnosed HIV. Expansion of HIV/sexually transmitted infection screening is needed to increase detection of HIV and linkage to care for sex workers. Interventions to reduce HIV infection among CWSWs and TWSWs should be tailored to these populations' unique vulnerabilities.

Abstract
BACKGROUND Street-based female sex workers (FSWs) are highly at risk of HIV and other harms associated with sex work. We assessed the prevalence of non-injection and injection drug use and their associated factors among street-based FSWs in Iran. METHODS We recruited 898 FSWs from 414 venues across 19 major cities in Iran between October 2016 and March 2017. Correlates of lifetime and past-month non-injection and injection drug use were assessed through multivariable logistic regression models. Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were reported. RESULTS Lifetime and past-month non-injection drug use were reported by 60.3% (95% CI 51, 84) and 47.2% (95% CI 38, 67) of FSWs, respectively. The prevalence of lifetime and past-month injection drug use were 8.6% (95% CI 6.9, 10.7) and 3.7% (95% CI 2.6, 5.2), respectively. Recent non-injection drug use was associated with divorced marital status (AOR 2.00, 95% CI 1.07, 3.74), temporary marriage (AOR 4.31 [1.79, 10.40]), had > 30 clients per month (AOR 2.76 [1.29, 5.90]), ever alcohol use (AOR 3.03 [1.92, 6.79]), and history of incarceration (AOR 7.65 [3.89, 15.30]). Similarly, lifetime injection drug use was associated with ever alcohol use (AOR 2.74 [1.20-6.20]), ever incarceration (AOR 5.06 [2.48-10.28]), and ever group sex (AOR 2.44 [1.21-4.92]). CONCLUSIONS Non-injection and injection drug use are prevalent among street-based FSWs in Iran. Further prevention programs are needed to address and reduce harms associated with drug use among this vulnerable population in Iran.

[PMID: 32621376 PMCID: PMC7779750 DOI: 10.1111/add.15182] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 04/02/2020] [Accepted: 06/29/2020] [Indexed: 01/16/2023]
Abstract
BACKGROUND AND AIMS Income assistance is critical to the health and wellbeing of socio-economically marginalized people who use illicit drugs (PWUD). However, past literature paradoxically identifies unintended increases in drug-related harm coinciding with synchronized payments that may magnify signals for drug use. The scope of such harm has not been fully characterized among non-institutionalized populations. This study examined socio-demographic, health and drug use-related correlates of payment-coincident drug-related harm. DESIGN This observational study uses data from prospective community-based longitudinal cohorts of PWUD between December 2013 and May 2018. SETTING Vancouver, British Columbia, Canada. PARTICIPANTS A total of 1604 PWUD receiving monthly income assistance. Our sample included 586 (36.5%) women, 861 (53.7%) non-white participants and 685 (42.7%) people living with HIV. MEASUREMENTS The primary outcome was a self-reported composite measure of drug-related harm in the past 6 months coinciding with income assistance, including higher-frequency substance use, non-fatal overdose and service barriers or interruptions. Subanalyses disaggregated this outcome. FINDINGS Payment-coincident drug-related harm was reported among 77.7% of participants during the study period. In multivariable models, key correlates positively and significantly associated with payment-coincident harm included: street-based income generation [adjusted odds ratio (aOR) = 1.48, 95% confidence interval (CI) = 1.26-1.74, P < 0.001], sex work (aOR = 1.66, 95% CI = 1.35-2.04, P < 0.001), illegal income generation (aOR = 1.57, 95% CI = 1.35-1.83 P < 0.001), homelessness (aOR = 1.34, 95% CI = 1.13-1.58, P < 0.001), exposure to violence (aOR = 1.31, 95% CI = 1.03-1.66, P = 0.032), daily crack cocaine use (aOR = 1.99, 95% CI = 1.59-2.50, P < 0.001), heavy alcohol use (aOR = 1.64, 95% CI = 1.37-1.97, P < 0.001) and injection drug use (aOR = 2.55, 95% CI = 2.01-3.23, P < 0.001). In subanalyses, specific harms were more likely among individuals reporting social, structural and health vulnerabilities. CONCLUSIONS In Vancouver, Canada, people who use illicit drugs who receive income assistance report high prevalence of payment-coincident drug-related harm, particularly people experiencing socioeconomic and structural marginalization or engaging in high-intensity drug use.

Daily activity spaces and drug use among female sex workers living with HIV in the Dominican Republic. Health Place 2021; 68:102527.

Abstract
The purpose of this study was to explore the daily activity spaces of female sex workers living with HIV in the Dominican Republic and assess the relationship between activity path and location-based risk exposure measures and daily drug use. The study employed a micro-longitudinal observational study design using an innovative 7-day travel diary to capture daily activity routes and a 7-day mobile health (mHealth) daily diary to collect daily substance use behaviors among 51 female sex workers. To estimate between-subject variability, a series of crude and adjusted modified log-Poisson repeated measures regression models with generalized estimating equations, clustering by individual with a compound symmetry working correlation structure were fit to estimate the relative risks and 95% confidence intervals. Controlling for individual level factors, findings showed that female sex workers exposed to a higher number of risk outlets (e.g., liquor stores, bars, hotels, nightclubs, brothels, etc.) within 200 and 100-meters of sex work locations were at an increased risk of daily drug use (RRadj: 1.03, 95%CI: 1.01, 1.05, RRadj: 1.05, 95%CI: 1.01, 1.09). No association was detected between activity path exposure and daily drug use. These findings illustrate the importance of moving beyond static residential neighborhood boundaries for measuring risk exposures and highlight the significant role that daily work environments have on drug harms among a highly stigmatized and vulnerable population.

Modelling the effect of market forces on the impact of introducing human immunodeficiency virus pre-exposure prophylaxis among female sex workers. HEALTH ECONOMICS 2021; 30:659-679.

Abstract
Pre-exposure prophylaxis (PrEP) to prevent human immunodeficiency virus (HIV) enables female sex workers (FSWs) to protect themselves from HIV without relying on clients using condoms. Yet, because PrEP reduces HIV risk, financial incentives to not use condoms may lead to risk compensation: reductions in condom use and/or increases in commercial sex, and may reduce the price of unprotected sex. In this analysis, we integrate market forces into a dynamic HIV transmission model to assess how risk compensation could change the impact of PrEP among FSWs and clients. We parameterise how sexual behavior may change with PrEP use among FSWs using stated preference data combined with economic theory. Our projections suggest the impact of PrEP is sensitive to risk compensatory behaviors driven by changes in the economics of sex work. Condom substitution could reduce the impact of PrEP on HIV incidence by 55%, while increases in the frequency of commercial sex to counter decreases in the price charged for unprotected sex among PrEP users could entirely mitigate the impact of PrEP. Accounting for competition between PrEP users and nonusers exacerbates this further. Alternative scenarios where increases in unprotected sex among PrEP users are balanced by decreases in non-PrEP users have the opposite effect, resulting in PrEP having much greater impact. Intervention studies need to determine how HIV prevention products may change the economics of sex work and provision of unprotected sex to enable a better understanding of their impact.

Abstract
BACKGROUND Limited data exist in the United States on the prevalence of HIV among women who exchange sex. SETTING We estimate HIV prevalence of women who exchange sex from a 2016 survey in Chicago, Detroit, Houston, and Seattle and compare it with the prevalence of HIV among women of low socioeconomic status (SES), who did not exchange sex, and women in the general population. METHODS Women who exchange sex were recruited via respondent-driven sampling among some cities participating in National HIV Behavioral Surveillance, interviewed, and offered HIV testing. We estimate HIV prevalence and, using prevalence ratios, compare it with the prevalence among women of low SES who did not exchange sex in the 2013 National HIV Behavioral Surveillance cycle, and to women in the general population estimated using 2015 National HIV Surveillance data. RESULTS One thousand four hundred forty women reported exchange sex in 2016. Aggregated HIV prevalence was 4.9% [95% confidence interval (CI): 2.7 to 7.1] among women who exchanged sex, 1.6% (95% CI: 0.3 to 2.8) among women of low SES who did not exchange sex, and 0.6% (95% CI: 0.5% to 0.6%) among women in the general population. HIV prevalence among women who exchanged sex was 3.1 times (95% CI: 1.6 to 5.9) as high as among women of low SES who did not exchange sex, and 8.8 times (95% CI: 7.0 to 11.1) as high as among women in the general population. CONCLUSION HIV prevalence was significantly higher among women who exchanged sex compared with women in the general population and women of low SES who did not exchange sex.

Abstract
OBJECTIVES Empirical time trends in HIV prevalence in female sex workers (FSWs) are helpful to understand the evolving HIV epidemic, and to monitor the scale-up, coverage, and impact of ongoing HIV prevention and treatment programmes. DESIGN Serial HIV prevalence study. METHODS We analyzed time trends in HIV prevalence in FSWs accessing services at seven Sex Worker Outreach Programme (SWOP) clinics in Nairobi from 2008 to 2017 (N = 33 560). The Mantel--Haenszel test for trend and independent samples Kruskal--Wallis test were used to analyze categorical and continuous variables, respectively. Multivariable binomial regression was used to estimate prevalence ratios/year, adjusting for several covariates. RESULTS HIV prevalence decreased over time in all age groups. This was particularly evident among FSWs less than 25 years of age; HIV was 17.5% in 2008-2009, decreasing to 12.2% in 2010-2011, 8.3% in 2012-2013, 7.3% in 2014-2015, and 4.8% in 2016-2017 (P < 0.0001). Over time, FSWs reported increased condom use, particularly with regular partners, more frequent prior HIV testing, and were less likely to report a history of vaginal discharge (P < 0.0001). In adjusted analyses compared with 2008, HIV prevalence decreased in 2011 (aPR 0.64; 95% CI: 0.46-0.90), 2012 (aPR 0.58; 95% CI: 0.41-0.81), 2013 (aPR 0.53; 95% CI: 0.38-0.73), 2014 (aPR 0.48; 95% CI: 0.34-0.67), 2015 (aPR 0.50; 95% CI: 0.35-0.70), 2016 (aPR 0.40; 95% CI: 0.28-0.57), and 2017 (aPR 0.33; 95% CI: 0.22-0.50). CONCLUSION HIV prevalence has decreased among FSW accessing SWOP in Nairobi, Kenya. This decline is consistent with the scale-up of HIV prevention and treatment efforts, both in FSWs and in the general population.

Abstract
The HIV burden is high among female sex workers (FSW) in Ethiopia, yet HIV testing coverage is suboptimal. We conducted a cross-sectional survey among 137 FSW in Addis Ababa. We examined factors related to recent HIV testing and self-reported HIV serostatus using logistic regression. HIV prevalence was 10%; and among HIV-negative participants, 63% reported recent HIV testing. Involvement in sex work for ≥5 years (aOR 3.25; 95% CI 1.22, 8.69; p-value 0.02) and hormonal contraceptive use (aOR 3.37; 95% CI 1.09, 10.41; p-value 0.03) were significantly associated with recent HIV testing. Involvement in sex work for ≥5 years (aOR 13.13, 95% CI 1.31 132.01, p-value 0.03), drug use (aOR 8.02; 95% CI 1.36, 47.31; p-value 0.02), and having a job other than sex work (aOR 122.05, 95% CI 2.97 > 999.99, p-value 0.01) were significantly associated with self-reported HIV-positive serostatus. These results identify areas to target future HIV risk-reduction interventions for FSW in Ethiopia.

Abstract
INTRODUCTION Marginalization of sex work presents numerous risks for trans women (TW) engaged in the sex trade, including criminalization, traumatization, and contracting HIV. We identified socio-economic and HIV risk disparities among trans women sex workers and others who do sex work (TWSW/OWSW), and evaluated these disparities for TWSW/OWSW compared to TW not engaged in sex work from pre- and post-implementation of the US 2018 "Allow States and Victims to Fight Online Sex Trafficking Act" and "Stop Enabling Sex Traffickers Act" (FOSTA-SESTA). METHODS We analyzed 429 trans women (TW) from the Trans*National cohort study (2016-2019). Generalized estimating equations (GEE) characterized differences in socio-economic and HIV risk outcomes for TWSW/OWSW compared to TW not engaged in sex work over the study period. Adjusted, pre-to-post law changes in these outcomes for TWSW/OWSW versus TW not engaged in sex work were compared using difference-in-differences GEE regression analyses. RESULTS Over 18 months, TWSW/OWSW had higher adjusted odds of being unstably housed, having income from criminalized sources, experiencing transphobic hate crimes, experiencing discrimination from police/courts, being incarcerated, meeting sex partners in the street/public settings, meeting sex partners on Craigslist or other online forums (except dating apps), or engaging in condomless anal intercourse, (p < 0.01 for all comparisons); TWSW/OWSW also had a higher mean number of income sources (p = 0.03). One difference-in-differences analysis showed additive interaction: the adjusted mean number of income sources reported by TWSW/OWSW compared to those not engaged in sex work decreased from pre-to post-FOSTA-SESTA (from 1.79 to 1.48 for TWSW/OWSW and from 1.52 to 1.47 for TW not engaged in sex work; p = 0.01). CONCLUSIONS Disparities in socio-economic and HIV-related risk outcomes exist for TWSW/OWSW in San Francisco. There is an urgent need for comprehensive, long-term follow-up data of TW to accurately analyze policy effects, especially given the recent enactment of a number of other policies targeting TW.

Abstract
INTRODUCTION Female sex workers bear a disproportionate burden of HIV and other poor sexual and reproductive health (SRH) outcomes which has led to the tailoring of SRH interventions to mitigate risk. Understanding of the SRH vulnerabilities of young women who sell sex (YWSS) (16-24 years) in Southern Africa is under-represented in research which may result in a mismatch in current SRH interventions and service design. OBJECTIVE This paper is based on a sub-analysis of a qualitative study investigating the SRH of young women who sell sex (16-24 years) in Zimbabwe. We explored the differences in dynamics of SRH vulnerability amongst YWSS within the 16-24 year age band. METHODS In-depth interviews (IDIs) were conducted amongst key informants (n = 4), health care providers (n = 5), and peer educators (n = 16). Amongst YWSS, we conducted IDIs (n = 42) and focus group discussions (n = 30). Transcripts were inductively coded for emergent themes and categories. RESULTS Age and life stage determinants led to key differences in SRH vulnerabilities between younger (16-19 years) and older YWSS (20-24 years). These determinants emerged in the following ways: 1) distancing of younger participants from a "sex worker" identity leading to difficulties in identification and limiting intervention reach, 2) inexperience in dealing with clients and immature cognitive development leading to greater exposure to risk, and 3) the subordinate social position and exploitation of young participants within sex worker hierarchies or networks and lack of protective networks. CONCLUSIONS We highlight the presence of a diverse group of vulnerable young women who may be missed by sex worker programme responses. In future intervention planning, there is need to consider the age-related needs and vulnerabilities within a spectrum of young women involved in a wide range of transactional relationships to ensure that services reach those most vulnerable to poor SRH outcomes.

Abstract
Introduction: Transgender women (TW) face one of the highest HIV burdens worldwide. In Malaysia, 12.4% of TW are HIV infected, ∼30-fold higher than in the Malaysian adult population. Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention strategy, however, little is known about TW's willingness to use PrEP or their preferences for receiving PrEP. This study examined the correlates of Malaysian TW's willingness to use PrEP and their attitudes and preferences related to delivery of PrEP and PrEP-related care. Methods: Between June and August 2017, 361 TW in Malaysia completed an online survey about their knowledge of and willingness to use PrEP for HIV prevention. Results: Only 20.2% of participants had ever previously heard of PrEP and none were currently taking PrEP. The majority (82.5%) expressed high willingness to take PrEP and most participants met the World Health Organization (WHO) indication for PrEP (82.3%). In the multivariate model, lifetime hormone use, prior postexposure prophylaxis use, and having completed a high school education were associated with higher willingness to use PrEP, while injection drug use, older age, and Chinese ethnicity were associated with lower PrEP willingness. Conclusion: TW in Malaysia are highly willing to use PrEP for HIV prevention. Differences in willingness to use PrEP identified by education, ethnicity, substance abuse, and age suggest different strategies may be needed to scale-up PrEP for this diverse community of TW.

Abstract
Background Prostitutes in Iran are faced with many challenges and problems that pose risks to their health. Objective The present study is an attempt to identify and narrate the challenges and experiences of Iranian prostitutes based on a qualitative approach. Methods This qualitative study was conducted with a phenomenological approach in (2018) in Tehran, Iran. The data were collected through semi-structured interviews with 22 prostitutes who were selected using a snowball sampling method and analyzed with Colaizzi's method. In order to examine the quality of findings, Guba and Lincoln's measures were used. Results Data analysis results were classified into five main categories and 14 subcategories. The main issues are: The experience of violence, Heath risk, social ostracism, objectifying, and lack of social and legal supporting structures. Conclusion Prostitutes in Iran experience numerous problems at personal and social levels. By providing social, economic, and legal supports for them such as social services (e.g. educations on how to use contraceptives, how to have safe sexual intercourse, and free counseling services for mental support), we can improve their health and welfare.

Abstract
Violence is one of the primary contextual factors that significantly raise sex workers' sexually transmitted infection risk. The current study examines how violence affects sexual health behavior among commercial female sex workers in a red light district in Calcutta, India. The study which employs in-depth interviews of 37 commercial female sex workers also discusses an innovative multilayered strategy devised by the sex workers to combat violence through a community mobilization drive. The current study shows that the sex workers can confront the system that precipitates violence and actively engage with it to mitigate the impact of structural barriers to empowerment.

Abstract
BACKGROUND High number of unintended pregnancies-often leading to induced abortions-are reported among female sex workers (FSWs), highlighting a major unmet need for contraception. To better understand barriers to contraceptive use, we explored FSW's pregnancy perceptions and experiences of unintended pregnancy. We hypothesized that sex work exacerbates barriers to contraceptive use and that FSW's pregnancy perceptions and experiences of unintended pregnancy influence future commitment to contraceptive use. METHODS We conducted in-depth interviews with 11 FSWs (January-June 2019) in Dar es Salaam, Tanzania. We purposively sampled FSWs with a positive pregnancy test from those participating in a HIV vaccine preparedness cohort. We used open ended questions to explore how FSWs make decisions when facing barriers to contraceptive use, dealing with unintended pregnancy and adhering to contraceptive use after experiencing unintended pregnancy. All interviews were conducted in Kiswahili, audio-recorded, transcribed and translated into English. Grounded theory approach was used to analyse transcripts. Open and selective coding was performed using Nvivo software. RESULTS FSWs reported that sex work impedes good contraceptive behaviour because sex workers felt unable to negotiate consistent condom use, avoided health services due to stigma, missed monthly contraceptive supplies because of inconvenient clinic operating hours or skipped contraceptive pills when intoxicated after taking alcohol. FSWs who perceived pregnancy to be a burden terminated the pregnancy because of fear of loss of income during pregnancy or child rearing expenses in case child support was not assured by their partners. FSWs who perceived pregnancy to be a blessing decided to keep the pregnancy because they desired motherhood and hoped that children would bring prosperity. Family planning counselling and availability of contraceptives during postpartum care influenced the initiation of contraception among FSWs. Financial hardships related to childrearing or painful abortion experiences influenced FSWs' commitment to good contraceptive practices. CONCLUSION Our results demonstrate that FSWs face barriers to initiating and adhering to contraceptive use because of sex work stigma, inability to negotiate condoms and failure to access medical services at their convenience. Our findings underscore the need to integrate contraceptive services with HIV programs serving FSWs in their areas of work.

Abstract
INTRODUCTION Women sex workers (WSW) are one of key population on the HIV and other sexually transmitted infections (STIs) monitoring and evaluation. Socioeconomic, structural factors and other factors associated with the workplace influence exposure to these infections. The objectives of this study were to describe and compare the social characteristics, risk behaviours and HIV, Chlamydia and gonorrhoeae prevalence according to sex work site (street or highway, clubs and flats). METHODS Cross-sectional study on 400WSW in Catalonia. Socio-demographic, sex work and behavioral characteristics were collected through personal interview. Oral fluid and urine samples were collected to determine STI prevalence. RESULTS WSW that exercised in the street or highway presented more precarious conditions and a greater vulnerability related to socioeconomic factors: older population, with a lower education level and with less economic remuneration for their service. Other factors associated with lifestyle or behaviour was also observed: greater injecting drug use, longer sex work or vulnerabilities associated with structural or social determinants: less access to health services, higher proportion of forced relations and stay in prison. The overall HIV, Chlamydia and gonorrhoeae prevalence was 3.0%, 1.8% and 0.5%, respectively, and higher in women who exercised on the street or highway: 5.6%, 1.9% and 1.2%, respectively. CONCLUSION The information generated in this study will be useful for the design specific preventive interventions aimed at this group.

Abstract
This study investigated herpes simplex virus type 2 (HSV-2) seroprevalence utility as a predictor of HIV epidemic potential among female sex workers (FSWs) globally. We updated and analyzed a systematically-assembled database for paired HSV-2 and HIV seroprevalence measures among FSWs. The study identified 231 paired HSV-2/HIV prevalence measures from 40 countries. The pooled mean HIV prevalence using meta-analysis increased from 3.7% (95% CI 0.3-9.9%) among populations of FSWs with HSV-2 prevalence < 25% to 18.7% (95% CI 14.1-23.8%) among those with HSV-2 prevalence 75-100%. HIV prevalence was negligible in FSWs with HSV-2 prevalence ≤ 20% suggesting a threshold effect. Multivariable meta-regressions explained > 65% of HIV prevalence variation, and identified a strong positive HSV-2/HIV association. Compared to populations of FSWs with HSV-2 prevalence < 25%, adjusted odds ratios (AORs) of HIV infection increased from 2.8 (95% CI 1.2-6.3) in those with HSV-2 prevalence 25-49%, to 13.4 (95% CI 6.1-29.9) in those with HSV-2 prevalence 75-100%. HSV-2 is a strong predictor of HIV epidemic potential among FSWs. HSV-2 prevalence of 25-49% indicates potential for intermediate-intensity HIV epidemics, with higher levels indicative of large epidemics. HSV-2 surveillance could inform HIV preparedness in countries where HIV prevalence among FSWs is still limited or at zero-level.

Abstract
ABSTRACTFemale sex workers (FSWs) are at increased risk of HIV and face significant barriers to clinic-based HIV testing, including provider stigma and privacy constraints. HIV self-testing (HIVST) has been proven to significantly increase HIV testing among FSWs. Less is known, however, about how FSWs make meaning of oral-fluid HIV self-tests, and the unintended ways they use and understand this novel technology. From October 2016 to March 2017, we conducted 61 in-depth interviews with FSWs (n = 31) in Kampala, Uganda. Eligible participants were: female, ≥18 years, exchanged sex for money or goods, and had not recently tested for HIV. We used inductive coding to identify emerging themes and re-arranged these into an adapted framework. Unintended desirable ways FSWs described self-testing included as a means to test others, to bolster their reputation as a health-conscious sex worker, and to avoid bearing witness to suffering at health facilities. Unintended undesirable meanings ascribed to self-testing included misunderstandings about how HIV is transmitted (via saliva versus blood) and whether self-tests also test for other infections. HIVST can increase FSWs' knowledge of their own HIV status and that of their sexual partners, but messaging and intervention design must address misunderstandings and misuses of self-testing.Trial registration: ClinicalTrials.gov identifier: NCT02846402.

Abstract
BACKGROUND Violence reduces sex workers' ability to enforce consistent condom use. Less is known of violence and condom use among gender diverse sex workers in Jamaica, where both sex work and same-sex practices are criminalized. We examined pathways from violence to consistent condom use among sex workers in Jamaica. METHODS We conducted a cross-sectional survey with a peer-driven sample of sex workers (n = 340: n = 124 cisgender men, n = 115 cisgender women, n = 101 transgender women) in Kingston, Ocho Rios, and Montego Bay, Jamaica. We conducted structural equation modeling using weighted least square estimation methods to test the direct effects of police harassment (ever), intimate partner violence (IPV) (ever), and recent (past 6-month) client violence on consistent condom use, and indirect effects via condom use self-efficacy, adjusting for socio-demographic factors. Moderation analysis was conducted to estimate the effect of binge drinking on condom use self-efficacy. We conducted a second SEM taking into consideration measurement invariance to test gender differences. RESULTS Over half of participants reported police harassment, half intimate partner violence, and one-third client violence. Overall, the direct path from police harassment to consistent condom use was significant. Condom use self-efficacy mediated associations between client violence and IPV with consistent condom use. Binge drinking moderated the association between client violence and condom use self-efficacy. There were gender differences in these pathways. CONCLUSIONS Violence has direct and indirect effects on condom use outcomes among sex workers in Jamaica. Multilevel, gender-tailored interventions at policy, police, and community levels can promote sex workers' health and human rights.

Abstract
Female entertainment and sex workers (FESW) are vulnerable to violence, which impedes safer sex behaviors and increases risk of HIV. FESW are also disproportionately affected by co-occurring psychosocial health conditions, including substance use, depression, and economic insecurity, which increased risk of exposure to violence. We used a syndemic framework to examine the effects of co-occurring psychosocial conditions on the risk of client-perpetrated physical and sexual violence against FESW. Data were collected among 1198 Cambodian FESW on recent client-perpetrated physical and sexual violence, and psychosocial conditions (psychological distress, alcohol consumption, amphetamine-type stimulant (ATS) use, debts, housing, and food insecurity). Bivariate and multivariate logistic regressions were conducted. Prevalence of physical and sexual violence from clients was 4.8% and 6.9%, respectively. Client-perpetrated physical violence was associated with housing insecurity, ATS use, and psychological distress. All psychosocial conditions, except ATS, were associated with exposure to sexual violence. In multivariable models, odds of client-perpetrated physical violence were twice higher among women with ≥ 4 compared to ≤ 3 psychosocial conditions. Risk of sexual violence increased with the number of psychosocial conditions. Compared to those with ≤ 1 condition, FESW with two psychosocial conditions had twice the odds (AOR = 2.08; 95% CI 1.00-4.31) and women with 5-6 psychosocial conditions had eightfold higher odds (AOR = 8.10; 95% CI 3.4-19.31) of sexual violence from clients. Our findings support a syndemic model of co-occurring psychosocial conditions among FESW that are associated with increased risk of violence. Violence prevention interventions targeting FESW should adopt comprehensive approaches that address co-occurring psychosocial conditions.

Abstract
Early sex work initiation among female sex workers (FSWs) increases their vulnerabilities to high-risk sexual practices and sexually transmitted infections (STIs). We examined the association of early sex work with condomless sex indicators, HIV, and other STIs, including human papillomavirus, chlamydia, trichomoniasis, syphilis, and gonorrhea, among FSWs in Iran. We recruited 1347 FSWs from 13 cities in 2015, with 1296 participants (94.2%) reporting information about their age of sex work initiation. Early sex work was defined as the initiation of selling sex before 18 years of age. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were reported using multivariable logistic regression. Overall, 10.1% of FSWs reported early sex work initiation. FSWs who initiated sex work earlier were more likely to report last-month inconsistent condom use (aOR = 3.31, 95% CI: 1.82, 6.02) and condomless sex with last client (aOR = 1.72, 95% CI: 1.15, 2.56). There was no statistically significant association between early sex work and HIV (aOR = 1.40, 95% CI: 0.43, 4.53) and any other STIs (aOR = 1.01, 95% CI: 0.69, 1.48), except for chlamydia (aOR = 2.09, 95% CI: 1.08, 4.04). These findings suggest that FSWs with early sexual debut would benefit from differentiated interventions including screening for STIs and enhanced counseling for condom use.

Abstract
We assessed prevalence of human immunodeficiency virus (HIV) risk behaviors and depressive symptoms among adolescent girls and young women (AGYW) aged 15-24 years attending four public family planning clinics in Western Kenya from January to June 2019. Moderate-to-severe depression (MSD) was defined as a Center for Epidemiologic Studies Depression Scale (CESD-10) score ≥10. Among 487 AGYW, the median age was 22 years (interquartile range 20-23), and 59 (12%) AGYW reported MSD. MSD was more prevalent among AGYW without a current partner (p = 0.001) and associated with HIV risk factors including partner ≥10 years older, recent transactional sex, forced sex, intimate partner violence, and alcohol use (each p ≤ 0.005). Thirty-four percent of AGYW with MSD had a high HIV risk score corresponding to 5 to 15 incident HIV cases per 100 person-years. Overlapping high prevalence of depression and HIV risk among AGYW underscores the need for integrated mental health and HIV services in family planning clinics.

Abstract
Condom use remains a mainstay of HIV prevention programs around the world. However, data characterizing economic determinants of condom use among female sex workers (FSW) are limited, including in Senegal. We recruited 718 FSWs via respondent-driven sampling. Bivariate and multivariable regressions were conducted to assess the associations between economic variables and condom use at last sex. Paying rent (aRR: 1.07, 95%CI 1.01-1.13) was positively associated with condom use at last sex with new clients. No statistically significant associations were found between condom use and financial responsibility for dependent children, having additional source of income, sharing sex work earnings, or the ability to borrow from other FSWs, regardless of sexual partner types. The relationship between economic marginalization and consistent condom use among sex workers is complex reinforcing the need for behavioral economic research and prevention to be integrated into HIV prevention and treatment research and programs.
