Environmental-structural factors significantly associated with consistent condom use among female sex workers in the Dominican Republic

Reducing intersectional stigma among transgender women in Brazil to promote uptake of HIV testing and PrEP: study protocol for a randomised controlled trial of Manas por Manas

INTRODUCTION

Globally, transgender ('trans') women experience extreme social and economic marginalisation due to intersectional stigma, defined as the confluence of stigma that results from the intersection of social identities and positions among those who are oppressed multiple times. Among trans women, gender-based stigma intersects with social positions such as engagement in sex work and substance use, as well as race-based stigma to generate a social context of vulnerability and increased risk of HIV acquisition. In Brazil, trans women are the 'most at-risk' group for HIV, with 55 times higher estimated odds of HIV infection than the general population; further, uptake of HIV testing and pre-exposure prophylaxis (PrEP) among trans women is significantly lower than other at-risk groups. Through extensive formative work, we developed Manas por Manas, a multilevel intervention using HIV prevention strategies with demonstrated feasibility and acceptability by trans women in Brazil, to address intersectional stigma and increase engagement in the HIV prevention continuum.

METHODS AND ANALYSIS

We are conducting a two-arm randomised wait-list controlled trial of the intervention's efficacy in São Paulo, Brazil, to improve uptake of HIV testing and PrEP among transgender women (N=400). The primary outcomes are changes in HIV testing (self-testing and clinic based), changes in PrEP uptake and changes in PrEP persistence at baseline and follow-up assessment for 12 months at 3-month intervals.

ETHICS AND DISSEMINATION

This study was approved by University of California, San Francisco Institutional Review Board (15-17910) and Comissão Nacional de Ética em Pesquisa (Research Ethics National Commission, CAAE: 25215219.8.0000.5479) in Brazil. Participants provided informed consent before enrolment. We are committed to collaboration with National Institutes of Health officials, other researchers, and health and social services communities for rapid dissemination of data and sharing of materials. The results will be published in peer-reviewed academic journals and scientific presentations.

Substance Use and Depression Impede ART Adherence Among Female Sex Workers Living with HIV in the Dominican Republic

Female sex workers (FSW) have worse HIV outcomes in part due to lower anti-retroviral therapy (ART) adherence. Substance use and depression are important barriers to ART adherence, yet few studies have assessed these relationships among FSW in longitudinal studies. Cross-Lagged Panel Models and autoregressive mediation analyses assessed substance use (illicit drug use and alcohol use disorders) in relation to ART non-adherence and the mediation role of depressive symptoms among 240 FSW living with HIV in the Dominican Republic. In annual visits (T1, T2, T3), the majority (70%, 66%, and 53%) reported at-risk drinking and 15%, 13% and 9% used illicit drug during the past 6 months. Most FSW (70%, 62% and 46%) had mild-to-severe depression. Illicit drug use predicted later ART non-adherence. This relationship was not mediated via depressive symptoms. Integrated substance use and HIV care interventions are needed to promote ART adherence and viral suppression among FSW.

Stigma in a Collectivistic Culture: Social Network of Female Sex Workers in China

In this egocentric network study, we explored Chinese collectivism in relation to social network characteristics and sex work-related stigma among mid-age female sex workers (FSWs). Respondent-driven sampling was used to recruit 1245 mid-age FSWs from three cities in China. We found that a one standard deviation (SD) increase in FSWs' collectivism was associated with a 0.18 SD decrease in social support (95% CI - 0.32, - 0.04), a 0.20 SD decrease in network effective size (i.e., the diversity of a social network; 95% CI - 0.30, - 0.10), and a 0.21 SD decrease in network betweenness (i.e., the "bridging potential" of egos within their networks; 95% CI - 0.33, - 0.09). Among participants who perceived more sex work stigma, the association between collectivism and FSWs' network betweenness was attenuated. In a collective culture emphasizing group values and honor, belonging to a less interconnected social network may give FSWs a structural advantage to cope with stigma and secure social support.

Social Support Associated with Condom Use Behavior Among Female Sex Workers in Iran

BACKGROUND

Despite the widespread knowledge about social support and health, there is little information about the association between social support and HIV risk behaviors such as condom use among female sex workers (FSWs) in Iran. This study aimed to determine the association between social support and frequency of condom use among FSWs in Tehran, Iran.

METHODS

Using mixed sampling methods, we recruited 170 FSWs in Tehran in 2017. We measured self-reported social support by face-to-face interviews using a standardized questionnaire. Linear regression was used to assess the association between socio-demographic characteristics (age, education level, marital status, and place of living), transactional sex characteristics (age at first transactional sex and frequency of transactional sex in the last month), HIV knowledge, social support network characteristics (social network size, duration of tie, intimacy, social support), and condom use behavior.

RESULTS

Of the total of 1193 persons in FSW's social networks, 615 (51%) were sexual partners, 529 (44%) were peer sex workers, and 36 (5%) were family members. The participants perceived moderate social support from sexual partners, low from peer sex workers, and very low from family members. Adjusted for individual and other network characteristics, peer sex worker social support (b = 0.28, 95%CI 0.06, 0.50), and family support (b = 1.12, 95%CI 0.028, 2.23) were significantly associated with condom use.

CONCLUSION

Family and peer sex worker social support are associated with condom use, but less strongly than HIV knowledge or place of living. However, very few FSWs are socially connected with families. Interventions to promote condom use among this vulnerable population should also consider social and familial support.

Determinants of safe sexual behavior of female sex workers in Tehran: the woman, her network, and the sexual partner

BACKGROUND

Despite the steady growth of sexual transmission of HIV, there is little evidence about safe sexual behavior of FSWs, and social network effects on this behavior, in Iran. Our aim in this study was to determine the effect of social network characteristics on condom use among FSWs, considering individual characteristics of the FSWs and of their sexual partners, characteristics of their relationship, and the FSW's personal network.

METHODS

A cross-sectional ego-centric network survey of 170 FSWs was carried out in Tehran between January and June 2017. A multilevel ordered logistic regression analysis was conducted to examine the effects of individual and relational characteristics simultaneously.

RESULTS

Condom use in sexual relationships of the FSWs on average was rather low. Important determinants of safe sexual behavior were found both at the level of the individual FSW and at the level of the sexual partner. The main determinants at the level of the individual FSW were FSWs' age and HIV knowledge. At the level of the sexual partner, age and education of sexual partners, as well as intimacy, duration of tie, frequency of contacts with a given partner, frequency of contact, perceived social support, and perceived safe sex norms were significantly associated with condom use.

CONCLUSIONS

The findings highlighted that considering only the individual characteristics of female sex workers is not sufficient for effectively promoting condom use. Factors at the network and dyadic level should also be considered, especially the role of sexual partners. Network-based interventions may be useful which modify social relationships to create a social environment that can facilitate changes in sexual behavior.

Intimate Relationships and HIV Infection Risks Among Shan Female Sex Workers From Myanmar in Chiang Mai, Thailand: A Qualitative Study

This study aimed to investigate HIV risks among female sex workers (FSWs) who were from the Shan ethnic group, and how they relate to complex relationships with inconsistent condom use. The study was conducted using in-depth interviews with 17 Shan FSWs (aged 18-45 years old) in Chiang Mai. Intimate relationships between participants and regular clients/steady partners were found to facilitate inconsistent condom use. Participating Shan FSWs sustained intimacy with regular clients not only for economic ends but also for emotional support. Gender norms and male power dominated condom use decision making. Some participants lacked proper HIV preventive knowledge regarding condom breakage and HIV risks. Effective intervention and proper HIV preventive practices should address these intimate contexts. Capacity building among women would assist FSWs to make choices that protect them from HIV/STDs infections. Couples-based HIV interventions addressing emotional intimacy is an urgent need for HIV communication and service delivery in Thailand.

"A condom is compulsory": A qualitative study of condom use and negotiation strategies among female sex workers in Nepal

The objective of this qualitative study was to understand Nepali female sex workers' (FSWs) condom negotiation strategies. In 2016, we conducted 30 semi-structured, in-depth interviews with street- and brothel-based FSWs residing in Kathmandu, Nepal. Participants reported that their first entry into sex work typically occurred between the ages of 17-32, and the average duration of women's involvement with sex work was 8 years. FSWs reported high knowledge and awareness of condoms, and many women had used various sexual and reproductive health services. FSWs used three types of negotiation strategies: withholding or refusing sex, providing risk information, and direct request. While some FSWs believed that these strategies were useful and successful, we found that, for some women, condom negotiation strategies were difficult to implement due to fear of abuse and threats of violence by clients. Condom negotiation was further complicated by poverty and substance abuse, and several narratives revealed the influence of gender and social norms on safe sexual practices. The findings highlight the need for improved sexual health interventions that incorporate a range of negotiation strategies and techniques (e.g., nonverbal communication and reward strategies) and aim to mitigate harm and violence against FSWs.

Assessing and Addressing Social Determinants of HIV among Female Sex Workers in the Dominican Republic and Tanzania through Community Empowerment-Based Responses

PURPOSE OF REVIEW

This review describes social determinants of HIV in two geographic and epidemic settings, the Dominican Republic (DR) and Tanzania, among female sex workers (FSW), their influence on HIV outcomes including 90-90-90 goals, and the development and impact of tailored, context driven, community empowerment-based responses in each setting.

RECENT FINDINGS

Our review documents the significance of social determinants of HIV including sex work-related stigma, discrimination, and violence and the impact of community empowerment-based approaches on HIV incidence in Tanzania and other HIV prevention, treatment, and care outcomes, including care engagement and adherence, in the DR and Tanzania. Community empowerment approaches where FSW drive the response to HIV and strategically engage partners to target socio-structural and environmental factors can have a demonstrable impact on HIV prevention, treatment, and care outcomes. Such approaches can also support further gains towards reaching the 90-90-90 across geographies and types of epidemics.

Assessing Human Immunodeficiency Virus (HIV) Prevention Through Knowledge and Condom Use Among Female Sex Workers at the Border of Haiti and Dominican Republic

Geographic border studies are relatively scare, but have the potential to inform bilateral health policies that affect the well-being of female sex workers (FSWs) who work at these borders as well as those individuals who solicit their services, both groups being at high risk for human immunodeficiency virus (HIV). We applied bivariate and multivariate techniques to examine FSWs' HIV knowledge and condom use across three partner types, at the Haiti Dominican Republic border, using data from the Study on Sex Workers (n = 241, 2014). Condom use was significantly lower among FSWs on the Haitian side of the border compared to the Dominican side, yet levels of HIV knowledge were similar; specifically, 81% of respondents on the Dominican side reported using condoms every time they had sex with a client, compared to 38% of peers in Haiti (p < 0.001). After introducing controls, FSWs in Haiti continued to have lower odds of using condoms with clients (p < 0.001), noncommercial partners (p < 0.001), and regular partners (p < 0.05) compared to peers in the Dominican Republic. This unique border study highlights disparities in FSWs' condom use regardless of HIV knowledge. The lack of consistent condom use by FSWs in Haiti has the potential to exacerbate the HIV epidemic at the border and impact both nations' HIV incidence rates.

HIV prevalence, sexual risk behaviours and HIV testing among female sex workers in three cities in Sri Lanka: Findings from respondent-driven sampling surveys

Sri Lanka has a low-level HIV epidemic. This study aims to provide evidence on HIV, syphilis and hepatitis B (HBV) prevalence, sexual risk behaviours and utilisation of HIV prevention interventions among female sex workers (FSW) in the cities Colombo, Galle, and Kandy. Using respondent-driven sampling (RDS), we recruited a total of 458 FSW in Colombo, 360 in Galle and 362 in Kandy from November 2017 to March 2018. Participants provided biological specimens for testing for infections and completed a behavioural questionnaire. We found no HIV nor HBV infections in Galle and Kandy, and low HIV (0.4%) and HBV surface antigen (0.6%) prevalence in Colombo. FSW in Colombo had higher positivity on Treponema pallidum-particle agglutination test (8.4%) compared to Galle (2.0%) and Kandy (2.5%). About two thirds of FSW heard of HIV in each of the cities. Around 90% of FSW used condom at last sex with a client in both Colombo and Galle, but considerably less in Kandy (57.1%). However, lower proportion of FSW used condoms every time during sex with clients in the past 30 day: 22.9% of FSW in Colombo, 26.6% in Kandy and 68.4% in Galle. Across cities, 17.5%-39.5% of FSW reported being tested for HIV in the past 12 months or knowing HIV positive status. The commonest reasons for never testing for HIV was not knowing where to test (54.2% in Colombo, 41.8% in Galle, 48.1% in Kandy) followed by inconvenient testing location (23.7% in Colombo and 31.1% in Kandy). HIV has not yet been firmly established among FSW in three cities in Sri Lanka, but the vulnerability towards HIV and STIs is substantial. HIV interventions should be intensified by expanding community-based HIV testing approaches, increasingawareness of HIV risks and addressing socio-structural vulnerabilities of FSW to HIV.

Drug use, sexual risk, and structural vulnerability among female sex workers in two urban centers of the Dominican Republic: The EPIC study

BACKGROUND

Evidence in different countries suggest an association between sex work and drug use. In the Dominican Republic an estimated 60,000-100,000 women work in the sex industry. However, little is known about their drug use behaviors.

OBJECTIVE

To characterize the burden of drug use and examine correlates of these behaviors among female sex workers in the Dominican Republic.

METHODS

Data for this analysis comes from a cross-sectional study among key populations at risk for HIV. A community sample of female sex workers (N = 389) was recruited using passive and active recruitment strategies. Participants completed a behavioral survey between 2015 and 2016. Logistic regression models were constructed to examine predictors of drug use.

RESULTS

Protective factors against marijuana and crack or cocaine use included being heterosexual, having a higher level of education, regular employment, and fewer male sexual partners. Increased odds of crack or cocaine use were associated with incarceration, having slept in a place not meant for human habitation in the last six months, and having ever lived in a batey (a community around a sugar mill where workers and their families live). Participants that used marijuana were generally younger, while those that used crack or cocaine were older.

CONCLUSIONS

Our findings highlight characteristics of the social and economic environment that require further research to optimize prevention and care strategies for this population. Public health interventions are needed that address drug use, sexual risk-taking, and helping female sex workers and their families achieve a healthy life.

An ethnographic study of 'touristic escapism' and health vulnerability among Dominican male tourism workers

Health research on tourism has expanded over the past two decades, focusing on understanding how the social, economic, and political configuration of tourism zones might contribute to health vulnerabilities among the diverse populations that interact in these areas. While there are few studies of HIV and drug use interactions in the region, research has indicated that these two outcomes are often interwoven in tourism zones, potentially producing 'syndemics' of HIV infection and problematic drug use. One framework that has been used in public health research on tourism is one that we refer to as touristic escapism or situational disinhibition that may be heightened for some tourists while on vacation, potentially leading to the abandonment of normative constraints on behaviour and contributing to health risks such as unprotected sex or binge drinking. In this article, we draw upon tourism theory and ethnographic research with male tourism workers employed in two popular tourist areas of the Dominican Republic to explore whether touristic escapism offers insights in understanding health vulnerabilities within tourism spaces.

Addressing broader reproductive health needs of female sex workers through integrated family planning/ HIV prevention services: A non-randomized trial of a health-services intervention designed to improve uptake of family planning services in Kenya

BACKGROUND

Despite considerable efforts to prevent HIV and other sexually transmitted infections (STI) among female sex workers (FSW), other sexual and reproductive health (SRH) needs, such preventing unintended pregnancies, among FSW have received far less attention. Programs targeting FSW with comprehensive, accessible services are needed to address their broader SRH needs. This study tested the effectiveness of an intervention to increase dual contraceptive method use to prevent STIs, HIV and unintended pregnancy among FSW attending services in drop-in centers (DIC) in two cities in Kenya. The intervention included enhanced peer education, and routine screening for family planning (FP) needs plus expanded non-condom FP method availability in the DIC.

METHODS

We conducted a two-group, pre-/posttest, quasi-experimental study with 719 FSW (360 intervention group, 359 comparison group). Participants were interviewed at baseline and 6 months later to examine changes in condom and non-condom FP method use.

RESULTS

The intervention had a significant positive effect on non-condom, FP method use (OR = 1.38, 95%CI (1.04, 1.83)), but no effect on dual method use. Consistent condom use was reported to be high; however, many women also reported negotiating condom use with both paying and non-paying partners as difficult or very difficult. The strongest predictor of consistent condom use was partner type (paying versus non-paying/emotional); FSW reported both paying and non-paying partners also influence non-condom contraceptive use. Substantial numbers of FSW also reported experiencing sexual violence by both paying and non-paying partners.

CONCLUSIONS

Self-reported difficulties with consistent condom use and the sometimes dangerous conditions under which they work leave FSW vulnerable to unintended pregnancy STIs/HIV. Adding non-barrier FP methods to condoms is crucial to curb unintended pregnancies and their potential adverse health, social and economic consequences. Findings also highlight the need for additional strategies beyond condoms to reduce HIV and STI risk among FSW.

HIV testing behaviour and HIV prevalence among female sex workers in Ukraine: findings from an Integrated Bio-Behavioural Survey, 2013-2014

OBJECTIVES

Ukraine has one of the largest HIV epidemics in Europe, with high prevalence among female sex workers (FSWs). We aimed to identify factors associated with HIV testing and receipt of the test result in the last 12 months, HIV prevalence and self-reported positive status among FSWs in Ukraine.

METHODS

We used data from an Integrated Bio-Behavioural Survey among FSWs conducted in 2013-2014. The survey methodology combined three sampling strategies: time and location sampling, respondent-driven sampling and key informant recruitment. We used multivariable regression to identify factors associated with self-reported HIV testing in the last 12 months, HIV prevalence and self-reported positive status among FSWs living with HIV. Explored factors included: age, age at first sex, age at entry into sex work, education, marital status, employment status beside sex work, condom use with last paying or non-paying sexual partner, drug or alcohol consumption and sex work venue.

RESULTS

Recent HIV testing was low overall with only 63.2% of FSWs reported having tested and received their test result in the last 12 months prior to the survey. HIV prevalence was 7.1% overall, but only 45.0% of FSWs living with HIV were aware of their HIV status. Testing in the last 12 months with receipt of test result was less common among FSWs who used drugs ever in life (adjusted OR (AOR) 0.7, 95% CI 0.6 to 0.9), women soliciting clients indoors (AOR 0.8, 95% CI 0.7 to 0.9) and those not using a condom with last paying sexual partner (AOR 0.3, 95% CI 0.2 to 0.5). HIV positivity was associated with history of ever using drugs (AOR 2.3, 95% CI 1.4 to 3.6) and soliciting clients outdoors (AOR 1.5, 95% CI 1.1 to 2.0). Women working indoors were less aware of their positive status (AOR 0.1, 95% CI 0.1 to 0.9).

CONCLUSION

HIV prevalence is high among FSWs in Ukraine, and testing and knowledge of one's status remain insufficient. HIV testing programmes need to expand with strategies to reach specific subgroups of FSWs.

Consistent Condom Use by Married and Cohabiting Female Sex Workers in India: Investigating Relational Norms with Commercial Versus Intimate Partners

This study examines determinants of consistent condom use (CCU) among married and cohabiting female sex workers (FSW) in India. Although CCU with clients is normative in the study area, most FSW do not consistently use condoms with intimate partners. Multiple logistic regression models indicated that condom use with intimate partners was associated with relationship status, cohabitation, HIV knowledge, STI symptoms, and being offered more money for sex without a condom by clients. Additionally, more days of sex work in the last week, serving as a peer educator, and participating in community mobilization activities were associated with higher odds of CCU across all partner types. Although improving economic security may increase CCU with clients, mobilization to reduce stigma and promote disclosure of sex work to non-cohabiting partners may be necessary to increase CCU overall.

Social cohesion, condom use, and sexually transmitted infections among female sex workers living with HIV in the Dominican Republic

This cross-sectional study examines the relationship between social cohesion with consistent condom use (CCU) and sexually transmitted infections (STIs) among the Abriendo Puertas (Opening Doors) cohort of female sex workers (FSWs) living with human immunodeficiency virus (HIV) in the Dominican Republic (n = 228). Using data from the follow-up survey of the cohort, we conducted multivariate logistic regression to explore these dynamics. Social cohesion was significantly associated with CCU between FSWs living with HIV and their clients in the last month (adjusted odds ratio [AOR] = 1.65, 95% confidence interval [CI]: 1.11-2.45) and STI prevalence among FSWs (AOR: 3.76, CI: 1.159-12.162). Social cohesion was not associated with CCU between FSWs living with HIV and their steady partners. However, both illicit drug use in the past six months (AOR = 0.11, CI: 0.023-0.57) and pregnancy intentions (AOR = 0.11; CI: 0.02-0.42) were significantly associated with CCU with steady partners. Findings highlight the differential role of social cohesion on condom use outcomes between FSWs living with HIV and their paying clients versus steady partners. Research on the pathways via which cohesion influences condom use among sex workers and their clients is merited, as is research regarding the role of drug use and pregnancy intentions on condom use with steady partners.

Social network and HIV risk behaviors in female sex workers: a systematic review

Background

Social network characteristics have an important role in understanding HIV transmission among female sex workers. The purpose of this systematic review was to summarize and critically appraise the existing studies on the social network characteristics and HIV risk behaviors among female sex workers.

Method

A systematic review was performed using predefined eligibility criteria through searching electronic databases. Two independent reviewers assessed the methodological quality of studies.

Results

Nineteen papers met the eligible review criteria. The synthesized evidence suggests that characteristics of social networks, especially functional characteristics such as social support and social capital, are important constructs for understanding the HIV risk behaviors.

Conclusions

The findings of the present review enhance our understanding of the role of social network characteristics in HIV risk behaviors among female sex workers. However, the findings also highlighted a dearth of knowledge about the association of structural characteristics of social networks with HIV risk behaviors among female sex workers.

HIV Testing and Counseling Among Female Sex Workers: A Systematic Literature Review

HIV testing uptake continues to be low among Female Sex Workers (FSWs). We synthesizes evidence on barriers and facilitators to HIV testing among FSW as well as frequencies of testing, willingness to test, and return rates to collect results. We systematically searched the MEDLINE/PubMed, EMBASE, SCOPUS databases for articles published in English between January 2000 and November 2017. Out of 5036 references screened, we retained 36 papers. The two barriers to HIV testing most commonly reported were financial and time costs—including low income, transportation costs, time constraints, and formal/informal payments—as well as the stigma and discrimination ascribed to HIV positive people and sex workers. Social support facilitated testing with consistently higher uptake amongst married FSWs and women who were encouraged to test by peers and managers. The consistent finding that social support facilitated HIV testing calls for its inclusion into current HIV testing strategies addressed at FSW.

Alcohol Use and HIV Risk Within Social Networks of MSM Sex Workers in the Dominican Republic

To examine how alcohol-related HIV risk behaviors within MSM sex workers' social networks (SN) may be associated with individual risk behaviors, respondent-driven and venue-based sampling were used to collect demographic, behavioral and SN characteristics among MSM sex workers in Santo Domingo and Boca Chica (N = 220). The majority of participants reported problem drinking (71.0%) or alcohol use at their last sexual encounter (71.4%). Self-reported problem drinking was associated with SN characteristics (at least one member who recently got drunk aOR = 7.5, no religious/spiritual adviser aOR = 3.0, non-sexual network density aOR = 0.9), while self-reported alcohol use at last sex was associated with individual (drug use at last sex aOR = 4.4) and SN characteristics (at least one member with previous HIV/STI testing aOR = 4.7). Dominican MSM sex workers reported high alcohol use, which may increase their risk for HIV. A better understanding of SN factors associated with individual risk behaviors can help guide appropriate intervention development.

Associations of HIV Testing, Sexual Risk and Access to Prevention Among Female Sex Workers in the Dominican Republic

The Caribbean region has one of the highest proportions of HIV in the general female population attributable to sex work. In 2008 (n = 1256) and 2012 (n = 1525) in the Dominican Republic, HIV biological and behavioral surveys were conducted among female sex workers (FSW) in four provinces using respondent driven sampling. Participants were ≥15 years who engaged in intercourse in exchange for money in the past 6 months and living/working in the study province. There were no statistically significant changes in HIV and other infections prevalence from 2008 to 2012, despite ongoing risky sexual practices. HIV testing and receiving results was low in all provinces. FSW in 2012 were more likely to receive HIV testing and results if they participated in HIV related information and education and had regular checkups at health centers. Further investigation is needed to understand barriers to HIV testing and access to prevention services.

A multi-level examination of the experiences of female sex workers living with HIV along the continuum of care in the Dominican Republic

Female sex workers (FSWs) are disproportionately affected by HIV, but there is limited research on their HIV care experiences. This study explored the experiences of 44 FSWs living with HIV in Santo Domingo, Dominican Republic along the HIV care continuum using in-depth interviews and focus groups. Data were analysed through narrative and thematic analysis. Individual-level factors that facilitated engagement in HIV care were physical and mental health. At the interpersonal level, disclosure of HIV or sex work status and receipt of emotional and economic support were important influences on engagement. Yet, negative reactions to or lack of disclosure of these statuses compromised engagement, further highlighting the role of stigma and discrimination. At the environmental level, FSWs described considerable challenges with the health system including long waits and treatment stock-outs at their clinics, but were generally satisfied with HIV clinic staff. At the structural level, lack of economic resources complicated care and treatment adherence. Findings underscore the need for psychosocial and economic support tailored to the unique needs of FSWs to maximise the individual and public health benefits of HIV care.

Psychosocial correlates of safe sex communication between Latina women and their stable male partners: an integrative review

Latina women in stable relationships have risks for human immunodeficiency virus and other sexually transmitted infections. Improving safe sexual communication (SSC) could enable women to accurately assess and mitigate their risk of infection within their relationship. Literature to identify psychosocial correlates that facilitate or inhibit SSC between Latina women and their partners has not yet been synthesized. The purpose of this study was to conduct an integrative review and synthesis of empirical and theoretical research that examines psychosocial correlates of SSC among adult Latina women from the United States, Latina America, and the Caribbean with stable male partners. A systematic search of LILACS, EBSCO, and PsychInfo databases was conducted to identify qualitative and quantitative studies that investigated psychosocial correlates of SSC among adult Latina women with a stable male partner. Pertinent data were abstracted and quality of individual studies was appraised. A qualitative synthesis was conducted following Miles and Huberman's method. Five qualitative and three quantitative studies meet eligibility criteria. Factors related to SSC related to three main themes: (1) relationship factors such as length, quality, and power/control, (2) individual factors including attitudes, beliefs, background, behaviors, and intrapersonal characteristics, and (3) partner factors related to partner beliefs and behaviors. The interplay of relationship, individual, and partner factors should be considered in the assessment of SSC for Latina women with their stable partners. To inform future interventions and clinical guidelines, additional research is needed to identify which factors are most related to SSC for this population, and how comparable experiences are for Latina women of different subcultures and living in different countries.

Lifetime Abortion of Female Sex Workers in Iran: Findings of a National Bio-Behavioural Survey In 2010

Introduction

Unintended pregnancies and abortion may be considered as occupational hazards for female sex workers (FSWs). As our understanding of contraceptive and abortion practices of Iranian FSWs is very limited, this study tries to assess the dynamics of contraception and abortion among this sub-population.

Methods

This survey was conducted in 2010, by recruiting 872 FSWs through facility-based sampling from 21 sites in 14 cities in Iran. Data were collected through face-to-face interviews using a pilot-tested standardized risk assessment questionnaire. We applied the logistic regression model to investigate the correlates of induced abortion among FSWs.

Results

Of the 863 participants with valid responses to the abortion variable, 35.3% (95% CI: 32.1–38.6) acknowledged ever induced abortion and the annual rate of abortion was estimated at 20.7 per 1000 women. Around 31.2% of FSWs reported no usual contraceptive use, 32.6% barrier method, 23.6% non-barrier modern contraception methods, and 12.5% dual protection. In our multivariable model, older age (Adjusted Odds Ratio (AOR) = 1.74, 95% Confidence Interval (CI): 1.02, 2.96), group sex (AOR = 1.92, 95% CI: 1.10, 3.35), history of travel for sex work (AOR = 1.55, 95% CI: 1.09, 2.20), sexual violence (AOR = 1.77, 95% CI: 1.25, 2.50), STIs in last year (AOR = 1.53, 95% CI: 1.09, 2.14), and accessing family planning services (AOR = 1.76, 95% CI: 1.24, 2.49) were significant predictors of lifetime abortion.

Conclusions

The reproductive health needs of Iranian FSWs are unmet and around one-third of FSWs reported induced abortion. Scaling-up comprehensive family planning services and empowering FSWs to have safer sex practices may help them to prevent unintended pregnancies and further risk of HIV transmission.

International migration from non-endemic settings as a protective factor for HIV/STI risk among female sex workers in Vancouver, Canada

Given heterogeneous evidence regarding the impacts of migration on HIV/sexually transmitted infections (STIs) among female sex workers (FSWs), we explored factors associated with international migration among FSWs in Vancouver, Canada. We draw on baseline questionnaire and HIV/STI testing data from a community-based cohort, AESHA, from 2010-2012. Logistic regression identified correlates of international migration. Of 650 FSWs, 163 (25.1%) were international migrants, who primarily worked in formal indoor establishments. HIV/STI prevalence was lower among migrants than Canadian-born women (5.5 vs. 25.9%). In multivariate analysis, international migration was positively associated with completing high school, supporting dependents, and paying a third party, and negatively associated with HIV, injecting drugs and inconsistent condom use with clients. Although migrants experience lower workplace harms and HIV risk than Canadian-born women, they face concerning levels of violence, police harassment, and HIV/STIs. Research exploring structural and socio-cultural factors shaping risk mitigation and migrants' access to support remains needed.

Condom Use During Commercial Sex Among Male Clients of Female Sex Workers in Sichuan China: A Social Cognitive Theory Analysis

There has been little theory-based research focusing on condom use among male clients of female sex workers (CFSW) in China. The current study applied social cognitive theory to condom use behaviors of CFSW in China. Face-to-face structured interviews were conducted among 584 CFSW recruited through snowball sampling. Bivariate and multivariate logistic regression models were applied to examine factors associated with consistent condom use. A minority (30.65 %) of respondents reported using condoms consistently with FSW, and 7 of 12 social cognitive dimensions/subdimensions were found to be significantly influential. The most significant factors were self-efficacy [adjusted prevalence ratio (APR) = 2.11, 95 %, CI = 1.74-2.43] and personal pleasure reduction (APR = 0.3, 95 % CI = 0.15-0.6). HIV-related knowledge, perceived HIV susceptibility, condom cost, condom efficacy, and embarrassment of carrying condoms were not associated with consistent condom uses with FSW. Findings from the current study suggest future prevention programs should target sex venues, and condom access should ensure both quantity and quality. Peer education should focus on knowledge education and peer norms, and knowledge education should include information on HIV infection severity and how to increase pleasure with condom use.

Factors Related to Pregnancy Among Female Sex Workers Living with HIV in the Dominican Republic

Female sex workers (FSWs) living with HIV are a vulnerable population for multiple health concerns and have been vastly understudied in public health literature. This study analyzes factors related to pregnancy among 268 FSWs living with HIV in the Dominican Republic. Results indicate that 34 % of participants had been pregnant since HIV diagnosis. Multivariate analysis revealed significant associations between pregnancy after HIV diagnosis and ART interruption (AOR 2.41; 95 % CI 1.19, 4.94), knowledge of mother-to-child transmission (AOR 2.12; 95 % CI 0.99, 4.55), serostatus disclosure to a sex partner (AOR 2.46; 95 % CI 1.31, 4.62), older age (AOR 0.91; 95 % CI 0.87, 0.95) and a more negative perception of their health provider (AOR 0.56; 95 % CI 0.34, 0.93). Results indicate noteworthy associations between having been pregnant and the health provider experience and ART interruption, indicating a significant need for further research on this population to ensure both maternal and child health.

Determining barriers to creating an enabling environment in Cambodia: results from a baseline study with key populations and police

Introduction

Cambodian law enforcement's limited acceptance of harm reduction has hindered HIV program effectiveness. With funding from the Australian Department of Foreign Affairs and Trade, FHI 360 supported the Ministry of Interior to implement the Police Community Partnership Initiative (PCPI) in Cambodia's capital Phnom Penh. To guide this, FHI 360 conducted a baseline study examining police and key populations’ attitudes and practices towards one another, including fear and occurrence of arrest.

Methods

Between December 2012 and January 2013, a cross-sectional survey of 199 police post officers, 199 people who use drugs (PWUD) including people who inject drugs (PWID), 199 men who have sex with men (MSM), 200 transgender women (TGW) and 200 female entertainment workers (FEW) was conducted in five Phnom Penh districts. Eligible participants were ≥18 years, members of a key population from selected hotspots or police officers, deputy chiefs or chiefs.

Results

Key populations’ median age was 25 years (IQR: 22–30); 40% had completed only primary school. Police were male (99.5%), with median age 43 years (IQR: 30 to 47), and 45 and 25% high school and university completion rates, respectively. Key populations feared arrest for carrying needles and syringes (67%), condoms (23%) and 19% felt afraid to access health services. Close to 75% of police reported body searching and 58% arresting key populations in the past six months for using drugs (64%), selling or distributing drugs (36%) or being violent (13%). Self-reported arrests (23% PWUD, 6% MSM, 6% TGW, 12% FEW; p<0.05), being verbally threatened (45% PWUD, 21% MSM, 25% TGW, 27% FEW; p<0.001) and body searched (44% PWUD, 28% MSM, 23% TGW, 8% FEW; p<0.001) was significantly higher among PWUD than other key populations. The majority (94%) of police believed arrest was an appropriate solution to reduce HIV and drug use and reported selling sex (88%) and carrying needles and syringes (55%) as valid reasons for arrest.

Conclusions

Key populations’ fear of accessing harm reduction and health services and police's negative attitudes and practices towards key populations present major barriers to HIV prevention efforts in Cambodia. To create an enabling environment and ensure police are allies in the Cambodian HIV response, interventions should tackle underlying negative attitudes among police towards key populations and vice versa.

Social Cohesion Among Sex Workers and Client Condom Refusal in a Canadian Setting: Implications for Structural and Community-Led Interventions

Community empowerment can be a powerful determinant of HIV risk among sex workers (SWs). This study modeled the impact of social cohesion on client condom refusal among SWs in Vancouver. Longitudinal data were drawn from a prospective cohort of SWs (2010-2013). Lippman and colleagues' Social Cohesion Scale measured SWs' connectedness (i.e., perception of mutual aid, trust, support). Multivariable logistic regression examined the independent effect of social cohesion on client condom refusal. Of 654 SWs, 22 % reported baseline client condom refusal and 34 % over 3 years. The baseline median social cohesion score was 24 (IQR 20-29, range 4-45). In the final confounding model, for every one-point increase in the social cohesion score, average odds of condom refusal decreased by 3 % (AOR 0.97; 95 % CI 0.95-0.99). Community empowerment can have a direct protective effect on HIV risk. These findings highlight the need for a legal framework that enables collectivization and SW-led efforts in the HIV response.

What role does transactional sex play in the HIV/STI and reproductive health risk behaviour among high-tier entertainment centre workers in China?

China's rapid economic growth over the last three decades has led to increased population wealth and the proliferation of entertainment centres where people can conduct business, relax and meet new people. Little is known about the sexual risk behaviours of employees at high-tier entertainment centres. This paper addresses this gap in knowledge by comparing HIV risk perception and sexual and reproductive health behaviours among female and male employees at three high-tier entertainment centres in two cities in China, comparing those who report a history of transactional sex to those who do not. In both cities, participants who reported a history of transactional sex were more likely than those without a history of transactional sex to report multiple sexual partnerships, more lifetime sexual partners, a history of sexually transmitted infections (STIs), having anal sex and/or recent abortions, and were more likely to perceive themselves to be at risk for STIs/HIV. However, risk behaviour was also high among those with no history of transactional sex. These findings highlight the need for targeted sexual and reproductive health initiatives for employees in these work settings.

A Framework for Sexual Decision-Making Among Female Sex Workers in Jamaica

The Jamaican government has provided targeted HIV and sexually transmitted infection prevention, treatment, and other services for female sex workers (FSW) since 1989. HIV prevalence among FSW declined from 20 to 12% between 1989 and 1994, then to 9% in 2005, 5% in 2008, and 4.1% in 2011. This article distills the literature and two decades of experience working with FSW in Jamaica. Drawing on the constant comparative method, we put forward an innovative conceptual framework for explaining sexual decision-making and risk behaviors within both transactional and relational sexual situations. This framework helps fill the gaps in existing models that focus on individual behaviors. The model identifies interactions between environmental and structural elements of sex work, and three individual-level factors: risk perception, perceived relationship intimacy, and perceived control, as the four primary mediating factors influencing sexual decision-making among FSW. We propose that other factors such as violence, socioeconomic vulnerability, and policy/legal frameworks influence sexual decision-making through these primary mediating factors. This conceptual model may offer a useful framework for planning and evaluating prevention interventions among sex workers. However, it remains to be tested in order to establish its value.

Psychological health and HIV transmission among female sex workers: a systematic review and meta-analysis

Current HIV prevention interventions for female sex workers (FSWs) have tended to target the cognitive factors in changing their behaviors, yet little attention has been paid to the psychological factors that influence the behavior of women in sex work. This review aimed to explore the associations between the psychological health of FSWs and HIV risk. A total of eight studies published in English before July 2013 were identified and reviewed. FSWs had reported psychological issues, including depression, suicidal thoughts as well as lower quality of life, and the pooled prevalence of probable depression was as high as 62.4%. The majority of studies showed that higher scores in psychological health problems were associated with increased HIV risk behavior, in particular inconsistent condom use, or sexually transmitted infections. Among the five studies which measured symptoms of depression, four documented that higher depression scores were significantly associated with inconsistent condom use among FSWs with their clients and/or partners. Meta-analysis using a fixed-effects model was performed to examine the association between depression and inconsistent condom use and found that higher scores in depression were significantly associated with inconsistent condom use (odds ratio = 2.57, p < .001). This review contends that future HIV preventive interventions should take psychological health of FSWs into consideration.

Understanding internalized HIV/AIDS-related stigmas in the Dominican Republic: a short report

HIV/AIDS-related stigmas can become internalized, resulting in declines in physical and mental health. Pathways to internalized HIV-related stigma (IS), characterized by persistently negative, self-abasing thoughts, are not well established among women living with HIV/AIDS (WLWHA) in the Dominican Republic (DR). Identifying factors involved in self-directed shaming and blaming is important, given the high HIV prevalence in the DR's most vulnerable populations. The present study sheds light on factors involved in negative and self-abasing thoughts in WLWHA in the DR by examining the relationship between depression, perceived HIV-related stigma from the community (PSC), perceived HIV-related stigma from family (PSF), and IS. The Internalized AIDS-Related Stigma Scale (IA-RSS), the Center for Epidemiologic Studies Short Depression Scale (CES-D 10), and an instrument designed to measure perceived HIV-related stigma from the community and family was administered to 233 WLWHA in Puerto Plata, DR. Data were analyzed using descriptive statistics and ordered multiple logistic regression. Results showed that depression (OR = 1.60; p < .05), PSC (OR = 3.68; p < .001), and PSF (OR = 1.60; p < .01) were positively associated with IS. These findings indicate that IS-reducing interventions should address HIV-related depression. Additionally, HIV-related treatment and care services should work with WLWHA to adopt healthier attitudes about how community members view people living with HIV/AIDS in the DR.

Addressing Structural and Environmental Factors for Adolescent Sexual and Reproductive Health in Low- and Middle-Income Countries

A deeper understanding of how structure and environment shape the sexual and reproductive health vulnerabilities of youths across a range of outcomes has implications for the development of successful policies and programs. We have discussed some of the key structural and environmental factors that influence the sexual and reproductive health of adolescents, particularly in low- and middle-income countries, and the importance of engaging adolescents in identifying solutions. We have highlighted 2 case studies that describe structural or environmental approaches to improving adolescent sexual and reproductive health and made recommendations to more systematically incorporate attention to structure and environment to improve global adolescent health.

Effectiveness of a Peer-Assisted Multicomponent Behavioral Intervention in HIV Risk Reduction Among Female Entertainment Workers in China

This study examined the effectiveness of a behavioral intervention that combined cognitive and social influence approaches. The intervention consisted of small group sessions targeting HIV knowledge, protection motivation, behavioral skills, and social influences of risk reduction. The control was an attention-controlled HIV/STI health education and counseling. Two-group comparisons were conducted to assess the effectiveness of the intervention; risk reduction over time was analyzed to determine the sustainability of the effectiveness. The analyses revealed that the intervention was effective in reducing/increasing HIV risk/protective behaviors and the effect was sustainable. While participants in the control reported a greater reduction/increase in risk/protective behaviors 3-month post-intervention, the initial strong effect quickly faded and completely disappeared 12-month post-intervention. By contrast, the moderate initial effect of the intervention was not only sustained but actually strengthened over time. The intervention was well received by participants and holds promise for HIV risk reduction behavior change among female entertainment workers in China.

Social Support and Sexual Risk Among Establishment-Based Female Sex Workers in Tijuana

Social support can affect health outcomes of female sex workers. In this inductive feminist grounded theory study based on 20 in-depth interviews, we explore how establishment-based female sex workers in Tijuana perceive the impact of the connections among women on their lives and health. Participants elected to discuss the importance of social support from mothers, sisters, friends, and co-workers, and the empowering and disempowering aspects of these relationships. In previous studies, scholars demonstrated the efficacy of formal organization of female sex workers in promoting the mitigation of sexual and HIV risk. We show the importance of informal ties with other women. Some participants mentioned competitive relationships, others talked about cooperation and the desire for a venue to learn from one another. Social interactions with other women are especially empowering when female sex workers can openly engage in "woman talk" that may contribute to the mitigation of sexual and HIV risk.

Contextual influence on condom use in commercial sex venues: A multi-level analysis among female sex workers and gatekeepers in Guangxi, China

This study aims to assess the influence of commercial sex venues on consistent condom use among female sex workers (FSWs) and to examine associations between individual and venue level factors and consistent condom use with clients. Analysis was based on a sample of 637 FSWs and 123 gatekeepers from 51 venues in Guangxi, China. Multi-level logistic regression using Bayesian simulation via Markov Chain Monte Carlo was applied to investigate whether FSWs' individual propensity to use condom with clients was statistically dependent on the venue of working. Multi-level modeling revealed considerable variability across venues in the likelihood of consistent condom use with clients among FSWs. Characteristics at both individual and venue levels helped to explain the observed variation. Certain venue-level factors exerted their influence on condom use over and above the effect of individual-level characteristics. The contextual influence exerted on condom use behaviors among FSWs may imply a potential to harness the path to individual behaviors from a higher and more dominant level, and shed light on the design of more effective sexual risk reduction intervention among venue-based FSWs.

West African female sex workers in Mali: reduction in HIV prevalence and differences in risk profiles of sex workers of differing nationalities of origin

BACKGROUND

Female sex workers (FSW) in Mali are highly vulnerable to HIV. Their prevalence in 2009 was 9 times higher (24.2%) than that among pregnant women (2.7%).

METHODS

Four Integrated HIV/sexually transmitted infection (STI) Surveillance and Behavioral Surveys among FSW in Mali (2000, 2003, 2006, and 2009) tracked demographic characteristics, behavior, and HIV and STI prevalence. Logistic regression using generalized estimating equations to control for the cluster effect identified factors associated with HIV-positive serostatus adjusting for potential confounding.

RESULTS

Of 2430 FSW, 40.8% were Nigerian, 36.8% were Malian, and 22.4% were from other neighboring countries. Between 2003 and 2009, HIV prevalence dropped from 44.14% to 28.49% (P < 0.0001) among Malians, from 21.33% to 12.71% (P = 0.0082) among Nigerians, and from 43.42% to 33.67% (P = 0.0442) among "others." Between 2000 and 2009, condom availability increased (89.18%-99.3%; P < 0.0001) as did HIV testing (40%-75%; P < 0.0001). Consistent condom use with clients improved for Malians (72.3%-81.5%; P = 0.0092), but not among Nigerians (92.7%-90.94%; P = 0.8240) and "others" (88.9%-88.48%; P = 0.8452). Consistent condom use with boyfriends was low and improved only for Nigerians (9.8%-28.4%; P = 0.0003). Factors associated with HIV prevalence in the multivariate model were older age, study year (2003 and 2006), nationality, lack of education, mobility, STI symptoms, gonorrhea prevalence, and younger age at first sex.

CONCLUSIONS

This study documents progress in the fight against HIV among FSW in Mali. The different vulnerabilities to HIV found for different nationality FSW should be considered in programming and future research.

Female sex workers' experiences with intended pregnancy and antenatal care services in southern Tanzania

Understanding the pregnancy experiences of female sex workers (FSWs), especially in the context of high rates of HIV and sexually transmitted infections (STIs), is essential to tailoring services to meet their needs. This study explores FSWs' experiences with intended pregnancy and access to antenatal care and HIV testing in two regions of Tanzania. Thirty in-depth interviews and three focus group discussions were conducted. FSWs sought to become pregnant to gain respect as mothers, to avoid stigma, and/or to solidify relationships, sometimes posing risks to their own and their partners' health. Pregnant FSWs generally sought antenatal care (ANC) services but rarely disclosed their occupation, complicating provision of appropriate care. Accessing ANC services presented particular challenges, with health care workers sometimes denying all clinic services to women who were not accompanied by husbands. Several participants reported being denied care until delivery. The difficulties participants reported in accessing health care services as both sex workers and unmarried women have potential social and health consequences in light of the high levels of HIV and STIs among FSWs in sub-Saharan Africa.

Violence prevention and municipal licensing of indoor sex work venues in the Greater Vancouver Area: narratives of migrant sex workers, managers and business owners

Using a socio-ecological, structural determinants framework, this study assesses the impact of municipal licensing policies and related policing practices across the Greater Vancouver Area (Canada) on the risk of violence within indoor sex work venues. Qualitative interviews were conducted with 46 migrant/immigrant sex workers, managers and owners of licensed indoor sex work establishments and micro-brothels. Findings indicate that policing practices and licensing requirements increase sex workers' risk of violence and conflict with clients and result in heightened stress, an inability to rely on police support, lost income and the displacement of sex workers to more hidden informal work venues. Prohibitive licensing and policing practices prevent sex workers, managers and owners from adopting safer workplace measures and exacerbate health and safety risks for sex workers. This study provides critical evidence of the negative public health implications of prohibitive municipal licensing in the context of a criminalised and enforcement-based approach to sex work. Workplace safety recommendations include the decriminalisation of sex work and the elimination of disproportionately high fees for licences, criminal record restrictions, door lock restrictions, employee registration requirements and the use of police as licensing inspectors.

A Synthesis of 20 Years of Research on Sexual Risk Taking Among Asian/Pacific Islander Men Who Have Sex With Men in Western Countries

Over the past two decades, there has emerged a body of literature documenting a number of risk factors associated with Asian/Pacific Islander men who have sex with men's unsafe sexual behaviors. This study aims to systematically review existing empirical studies and synthesize research results into a social-ecological framework using a mixed research synthesis. Empirical research articles published in peer-reviewed journals between January 1990 and June 2013 were identified in six databases, including PubMed, Ovid MEDLINE, PsycINFO, Social Work Abstract, CINAL, and Web of Knowledge. Both quantitative and qualitative studies were included. Two analysts independently reviewed the articles, and findings were organized on a social-ecological framework. Twenty-two articles were included in the analysis; among these 13 were quantitative, 8 were qualitative, and 1 was mixed-methods research. Results indicated that demographic characteristics, psychological resources, behavioral patterns, relationships with family and friends, dynamics with romantic or sexual partners, community involvement, culture, discrimination, and institutional factors were related to unprotected anal intercourse. This article presents a critique of this literature and discusses implications for future research with this population. It concludes with prevention/intervention initiatives based on review findings.

'If you have children, you have responsibilities': motherhood, sex work and HIV in southern Tanzania

Many female sex workers begin sex work as mothers, or because they are mothers, and others seek childbearing. Motherhood may influence women's livelihoods as sex workers and their subsequent HIV risks. We used qualitative research methods (30 in-depth interviews and three focus group discussions) and employed Connell's theory of Gender and Power to explore the intersections between motherhood, sex work, and HIV-related risk. Participants were adult women who self-reported exchanging sex for money within the past month and worked in entertainment venues in southern Tanzania. Participants had two children on average, and two-thirds had children at home. Women situated their socially stigmatised work within their respectable identities as mothers caring for their children. Being mothers affected sex workers' negotiating power in complex manners, which led to both reported increases in HIV-related risk behaviours (accepting more clients, accepting more money for no condom, anal sex), and decreases in risk behaviours (using condoms, demanding condom use, testing for HIV). Sex workers/mothers were aware of risks at work, but with children to support, their choices were constrained. Future policies and programming should consider sex workers' financial and practical needs as mothers, including those related to their children such as school fees and childcare.

Complexities of short-term mobility for sex work and migration among sex workers: violence and sexual risks, barriers to care, and enhanced social and economic opportunities

Despite research on the health and safety of mobile and migrant populations in the formal and informal sectors globally, limited information is available regarding the working conditions, health, and safety of sex workers who engage in short-term mobility and migration. The objective of this study was to longitudinally examine work environment, health, and safety experiences linked to short-term mobility/migration (i.e., worked or lived in another city, province, or country) among sex workers in Vancouver, Canada, over a 2.5-year study period (2010-2012). We examined longitudinal correlates of short-term mobility/migration (i.e., worked or lived in another city, province, or country over the 3-year follow-up period) among 646 street and off-street sex workers in a longitudinal community-based study (AESHA). Of 646 sex workers, 10.84 % (n = 70) worked or lived in another city, province, or country during the study. In a multivariate generalized estimating equations (GEE) model, short-term mobility/migration was independently correlated with older age (adjusted odds ratio (AOR) 0.95, 95 % confidence interval (CI) 0.92-0.98), soliciting clients in indoor (in-call) establishments (AOR 2.25, 95 % CI 1.27-3.96), intimate partner condom refusal (AOR 3.00, 1.02-8.84), and barriers to health care (AOR 1.77, 95 % CI 1.08-2.89). In a second multivariate GEE model, short-term mobility for sex work (i.e., worked in another city, province, or country) was correlated with client physical/sexual violence (AOR 1.92, 95 % CI 1.02-3.61). In this study, mobile/migrant sex workers were more likely to be younger, work in indoor sex work establishments, and earn higher income, suggesting that short-term mobility for sex work and migration increase social and economic opportunities. However, mobility and migration also correlated with reduced control over sexual negotiation with intimate partners and reduced health care access, and mobility for sex work was associated with enhanced workplace sexual/physical violence, suggesting that mobility/migration may confer risks through less control over work environment and isolation from health services. Structural and community-led interventions, including policy support to allow for more formal organizing of sex work collectives and access to workplace safety standards, remain critical to supporting health, safety, and access to care for mobile and migrant sex workers.

Prevalence and correlates of HIV and sexually transmitted infections among female sex workers and their non-commercial male partners in two Mexico-USA border cities

Female sex workers (FSWs) acquire HIV and other sexually transmitted infections (STIs) through unprotected sex with commercial and non-commercial (intimate) male partners. Little research has focused on FSWs' intimate relationships, within which condom use is rare. We sought to determine the prevalence and correlates of HIV/STIs within FSWs' intimate relationships in Northern Mexico. From 2010 to 2011, we conducted a cross-sectional survey of FSWs and their non-commercial male partners in Tijuana and Ciudad Juárez, Mexico. Eligible FSWs and their verified male partners were aged ≥18 years; FSWs reported lifetime use of heroin, cocaine, crack, or methamphetamine and recently exchanged sex (past month). Participants completed baseline questionnaires and testing for HIV, chlamydia, gonorrhea, and syphilis. We determined the prevalence and correlates of individuals' HIV/STI positivity using bivariate probit regression. Among 212 couples (n = 424), prevalence of HIV was 2.6 % (n = 11). Forty-two (9.9 %) tested positive for any HIV/STIs, which was more prevalent among women than men (12.7 % vs. 7.1 %, p < 0.05). FSWs with regular sex work clients were less likely to test positive for HIV/STIs than those without regular clients. Similarly, male partners of FSWs who had regular clients were 9 % less likely to have HIV/STIs. Higher sexual decision-making power was protective against HIV/STIs for women. Men who recently used methamphetamine or reported perpetrating any conflict within steady relationships were more likely to test positive for HIV/STIs. Within FSWs' intimate relationships in two Mexican-US border cities, nearly one in ten partners tested positive for HIV/STIs. Couple-based prevention interventions should recognize how intimate relationship factors and social contexts influence HIV/STI vulnerability.

Criminalisation of clients: reproducing vulnerabilities for violence and poor health among street-based sex workers in Canada-a qualitative study

OBJECTIVES

To explore how criminalisation and policing of sex buyers (clients) rather than sex workers shapes sex workers' working conditions and sexual transactions including risk of violence and HIV/sexually transmitted infections (STIs).

DESIGN

Qualitative and ethnographic study triangulated with sex work-related violence prevalence data and publicly available police statistics.

SETTING

Vancouver, Canada, provides a unique opportunity to evaluate the impact of policies that criminalise clients as the local police department adopted a sex work enforcement policy in January 2013 that prioritises sex workers' safety over arrest, while continuing to target clients.

PARTICIPANTS

26 cisgender and 5 transgender women who were street-based sex workers (n=31) participated in semistructured interviews about their working conditions. All had exchanged sex for money in the previous 30 days in Vancouver.

OUTCOME MEASURES

Thematic analysis of interview transcripts and ethnographic field notes focused on how police enforcement of clients shaped sex workers' working conditions and sexual transactions, including risk of violence and HIV/STIs, over an 11-month period postpolicy implementation (January-November 2013).

RESULTS

Sex workers' narratives and ethnographic observations indicated that while police sustained a high level of visibility, they eased charging or arresting sex workers and showed increased concern for their safety. However, participants' accounts and police statistics indicated continued police enforcement of clients. This profoundly impacted the safety strategies sex workers employed. Sex workers continued to mistrust police, had to rush screening clients and were displaced to outlying areas with increased risks of violence, including being forced to engage in unprotected sex.

CONCLUSIONS

These findings suggest that criminalisation and policing strategies that target clients reproduce the harms created by the criminalisation of sex work, in particular, vulnerability to violence and HIV/STIs. The current findings support decriminalisation of sex work to ensure work conditions that support the health and safety of sex workers in Canada and globally.

Early sex work initiation independently elevates odds of HIV infection and police arrest among adult sex workers in a Canadian setting

OBJECTIVES

To explore factors associated with early sex work initiation and model the independent effect of early initiation on HIV infection and prostitution arrests among adult sex workers (SWs).

DESIGN

Baseline data (2010-2011) were drawn from a cohort of SWs who exchanged sex for money within the last month and were recruited through time location sampling in Vancouver, Canada. Analyses were restricted to adults ≥18 years old.

METHODS

SWs completed a questionnaire and HIV/sexually transmitted infection testing. Using multivariate logistic regression, we identified associations with early sex work initiation (<18 years old) and constructed confounder models examining the independent effect of early initiation on HIV and prostitution arrests among adult SWs.

RESULTS

Of 508 SWs, 193 (38.0%) reported early sex work initiation, with 78.53% primarily street-involved SWs and 21.46% off-street SWs. HIV prevalence was 11.22%, which was 19.69% among early initiates. Early initiates were more likely to be Canadian born [adjusted odds ratio (AOR): 6.8, 95% confidence interval (CI): 2.42 to 19.02], inject drugs (AOR: 1.6, 95% CI: 1.0 to 2.5), and to have worked for a manager (AOR: 2.22, 95% CI: 1.3 to 3.6) or been coerced into sex work (AOR: 2.3, 95% CI: 1.14 to 4.44). Early initiation retained an independent effect on increased risk of HIV infection (AOR: 2.5, 95% CI: 1.3 to 3.2) and prostitution arrests (AOR: 2.0, 95% CI: 1.3 to 3.2).

CONCLUSIONS

Adolescent sex work initiation is concentrated among marginalized, drug, and street-involved SWs. Early initiation holds an independent increased effect on HIV infection and criminalization of adult SWs. Findings suggest the need for evidence-based approaches to reduce harm among adult and youth SWs.

Debe cuidarse en la calle: normative influences on condom use among the steady male partners of female sex workers in the Dominican Republic

Encouragement to use condoms reflects the injunctive norm, or idea that you should use condoms. In our previous research with the regular male partners of female sex workers, in the Dominican Republic, we found that encouragement to use condoms with female sex workers from individuals in their personal social networks was not directly associated with condom use. In the current study, we used qualitative interviews to further explore the influence of social network norms on men's sexual-risk behaviours. We interviewed 11 steady male partners of female sex workers, with participants completing two interviews to achieve greater depth. We analysed data using analytic summaries and systematic thematic coding. All men perceived that the prevailing injunctive norm was that they should use condoms with sex workers. Men received encouragement to use condoms but did not articulate a link between this encouragement and condom use. Additionally, men who did not use condoms lied to their friends to avoid social sanction. Findings highlight that the influence of a pro-condom injunctive norm is not always health promoting and can even be negative. HIV-prevention efforts seeking to promote condom use should address the alignment between injunctive and descriptive norms to strengthen their collective influence on behaviour.

Advancing the prevention agenda for HIV and other sexually transmitted infections in south China: social science research to inform effective public health interventions

Despite widespread biomedical advances in treatment and prevention, HIV and other sexually transmitted infections (STI) continue to affect a large portion of the world's population. The profoundly social nature of behaviorally driven epidemics and disparities across socioeconomic divides in the distribution of HIV/STI and care outcomes emphasize the need for innovative, multilevel interventions. Interdisciplinary approaches to HIV/STI control are needed to combine insights from the social and biological sciences and public health fields. In this concluding essay to a Special Issue on HIV/STI in south China, we describe the evolution of the region's HIV/STI epidemics and the government response, then synthesize findings from the 11 studies presented in this issue to extend seven recommendations for future HIV/STI prevention and care research in China. We discuss lessons learned from forging international collaborations between the social and biological sciences and public health to inform a shared research agenda to better meet the needs of those most affected by HIV and other STI.

Piloting a 'spatial isolation' index: the built environment and sexual and drug use risks to sex workers

BACKGROUND

Employing innovative mapping and spatial analyses of individual and neighbourhood environment data, we examined the social, physical and structural features of overlapping street-based sex work and drug scenes and explored the utility of a 'spatial isolation index' in explaining exchanging sex for drugs and exchanging sex while high.

METHODS

Analyses drew on baseline interview and geographic data (January 2010-October 2011) from a large prospective cohort of street and off-street sex workers (SWs) in Metropolitan Vancouver and external publically-available, neighbourhood environment data. An index measuring 'spatial isolation' was developed from seven indicators measuring features of the built environment within 50m buffers (e.g., industrial or commercial zoning, lighting) surrounding sex work environments. Bivariate and multivariable logistic regression was used to examine associations between the two outcomes (exchanged sex for drugs; exchanged sex while high) and the index, as well as each individual indicator.

RESULTS

Of 510 SWs, 328 worked in street-based/outdoor environments (e.g., streets, parks, alleys) and were included in the analyses. In multivariable analysis, increased spatial isolation surrounding street-based/outdoor SWs' main places of servicing clients as measured with the index was significantly associated with exchanging sex for drugs. Exchanging sex for drugs was also significantly positively associated with an indicator of the built environment suggesting greater spatial isolation (increased percent of parks) and negatively associated with those suggesting decreased spatial isolation (increased percent commercial areas, increased count of lighting, increased building footprint). Exchanging sex while high was negatively associated with increased percent of commercial zones but this association was removed when adjusting for police harassment.

CONCLUSIONS

The results from our exploratory study highlight how built environment shapes risks within overlapping street-based sex work and drug scenes through the development of a novel index comprised of multiple indicators of the built environment available through publicly available data, This study informs the important role that spatially-oriented responses, such as safer-environment interventions, and structural responses, such as decriminalization of sex work can play in improving the health, safety and well-being of SWs.
