Systematic review examining differences in HIV, sexually transmitted infections and health-related harms between migrant and non-migrant female sex workers

Differences in STI/HIV Burden and Sexual Health Care-Seeking Behavior Among First- and Second-Generation Migrant and Western-Born Male Sex Workers Who Have Sex With Men in the Netherlands: A Retrospective Cohort Study

BACKGROUND

Globally, migrant sex workers have a higher burden of sexually transmitted infections (STI)/human immunodeficiency virus (HIV). This large study aimed to assess demographics, STI/HIV burden, and sexual health care-seeking behavior of first-generation migrant and second-generation migrant male sex workers who have sex with men (MSW-MSM) versus Western-born MSW-MSM.

METHODS

Coded STI clinic consultations (n = 6970) from 3116 individual MSW-MSM attending any Dutch STI clinic between 2016 and 2021 were included. First-generation migrant: born outside of northern/central/southern/western Europe/North America/Oceania. Second-generation migrant: ≥1parent born outside of northern/central/southern/western Europe/North America/Oceania. Multivariable logistic regression analysis assessed associations between MSW-MSM groups and STI in first consultation in the data. A Cox proportional hazard regression compared the incidence of a first repeat consultation between migration groups, stratified by STI in first consultation. All analyses were adjusted for age and urbanity of STI clinic region.

RESULTS

First-generation migrant MSW-MSM (n = 1085) were mostly born in Latin America (50%), whereas second-generation migrant MSW-MSM (n = 368) mostly originated from North Africa (30.4%). The proportion of STI diagnoses differed (33.2%, 29.3%, 23.3%; P < 0.001) between the first-generation migrant, second-generation migrant, and Western-born MSW-MSM. First-generation migrant MSW-MSM versus Western-born had an adjusted odds ratio of 1.6 (95% confidence interval, 1.3-1.9) of STI diagnosis in the first consultation. First-generation migrant MSW-MSM versus Western-born had an adjusted hazard ratio of 1.5 (95% confidence interval, 1.3-1.8) of having a first repeat consultation at any time, when stratified for no STI in the first consultation.

CONCLUSIONS

The STI/HIV burden is high among all 3 MSW-MSM groups. First-generation migrants have higher odds of STI, but retention in care seems similar. Results highlight the importance of low-threshold STI testing and care for (migrant) MSW-MSM.

High PrEP uptake, adherence, persistence and effectiveness outcomes among young Thai men and transgender women who sell sex in Bangkok and Pattaya, Thailand: findings from the open-label combination HIV prevention effectiveness (COPE) study

Background

Daily oral pre-exposure prophylaxis (PrEP) is effective in preventing HIV infection, but no study has evaluated combination prevention interventions with PrEP for transgender women (TGW) and men who have sex with men (MSM) who sell sex.

Methods

The Combination Prevention Effectiveness (COPE) study was a community-based, non-randomized implementation study in Bangkok and Pattaya, Thailand. Participants were HIV-negative MSM and TGW aged 18-26 years who reported exchanging sex with men in the prior 12 months and who met 2014 U.S. Public Health Service PrEP eligibility criteria. The intervention included quarterly HIV testing, semiannual testing for sexually transmitted infections, provision of condoms with lubricant, and the opportunity to initiate or end daily oral PrEP use at any time during study participation. Participants taking PrEP received monthly adherence counseling and short message service reminders. The primary outcome was HIV incidence rate ratio (IRR) on PrEP vs. not on PrEP. Secondary outcomes were PrEP initiation, PrEP use at 12 months, and PrEP adherence.

Findings

From October 2017 to August 2019, 846 participants were enrolled: 531 (62.8%) immediately initiated PrEP; 104 (12.3%) subsequently initiated PrEP, and 211 (24.9%) never initiated PrEP. Among those initiating PrEP within 30 days of enrollment; 85.9% were on PrEP at the 12-months. When taking PrEP, participants reported adherent PrEP use at 94.2% of quarterly assessments. Ten HIV seroconversions occurred without PrEP use (incidence rate [IR] = 3.42 per 100 person-years [PY]; 95% CI = 1.64-6.30), while zero cases occurred with PrEP use (IR = 0.0 per 100PY; 95% CI = 0.0-0.62), with IRR = 0.0 (95% CI = 0.0-0.22; p < 0.001).

Interpretation

Young Thai MSM and TGW who exchange sex can have high PrEP uptake, persistence and adherence, and low HIV incidence when offered in supportive community-based settings.

A Confounding Discourse Analysis of Vietnamese Sex Workers' Talk in the City of Kaiyuan, China

BACKGROUND

Vietnamese female sex workers (VFSWs) cross the border into Kaiyuan City, Yunnan Province yearly. However, very little is known about both the health and psychological issues VFSWs experience. The objectives of this study were to explore the dominant discourses that emerged from the VFSWs' talk. The interviews occurred between May 2018 and June 2018 with 20 VFSWs who worked in Kaiyuan City, China. The English translated transcripts were analyzed using an eclectic feminist method of discourse analysis. Two discourses emerged. First, "Agency when working in Karaoke Bars and other Indoor Venues", and second, "Negative Impacts on Psychological Well-being and Other Problems from Migration." As for Discourse 1, the VFSWs positioned themselves as having agency over choosing their clientele as well as agency over what they were willing to negotiate with their clients to establish boundaries of their bodies. As for the Discourse 2, while there was a discourse of agency in their work there was also a contrasting, confounding discourse around the negative impact on psychological well-being and reports of stress as a migrant worker. Discourse 1 and Discourse 2 are confounding. When analyzed together, the discourses suggest that the impacts on psychological well-being may be more related to the migrant status of the women, supporting the notion of systemically influenced agency.

Health inequalities in infectious diseases: a systematic overview of reviews

OBJECTIVES

The aim of this systematic overview of reviews was to synthesise available evidence on inequalities in infectious disease based on three dimensions of inequalities; inclusion health groups, protected characteristics and socioeconomic inequalities.

METHODS

We searched MEDLINE, Embase, Web of Science and OpenGrey databases in November 2021. We included reviews published from the year 2000 which examined inequalities in the incidence, prevalence or consequences of infectious diseases based on the dimensions of interest. Our search focused on tuberculosis, HIV, sexually transmitted infections, hepatitis C, vaccination and antimicrobial resistance. However, we also included eligible reviews of any other infectious diseases. We appraised the quality of reviews using the Assessment of Multiple Systematic Reviews V.2 (AMSTAR2) checklist. We conducted a narrative data synthesis.

RESULTS

We included 108 reviews in our synthesis covering all the dimensions of inequalities for most of the infectious disease topics of interest, however the quality and volume of review evidence and consistency of their findings varied. The existing literature reviews provide strong evidence that people in inclusion health groups and lower socioeconomic status are consistently at higher risk of infectious diseases, antimicrobial resistance and incomplete/delayed vaccination. In the protected characteristics dimension, ethnicity, and sexual orientation are important factors contributing to inequalities across the various infectious disease topics included in this overview of reviews.

CONCLUSION

We identified many reviews that provide evidence of various types of health inequalities in different infectious diseases, vaccination, and antimicrobial resistance. We also highlight areas where reviews may be lacking. The commonalities in the associations and their directions suggest it might be worth targeting interventions for some high risk-groups that may have benefits across multiple infectious disease outcomes rather than operating purely in infectious disease siloes.

Low Behavioral Intention to Use Any Type of HIV Testing and HIV Self-Testing among Migrant Male Factory Workers Who Are at High Risk of HIV Infection in China: A Secondary Data Analysis

This study investigated the prevalence of and factors associated with behavioral intention to take up any type of HIV testing and HIV self-testing (HIVST) in the next six months among male migrant workers, who were at high risk of HIV infection, in Shenzhen, China. This was a secondary data analysis. A total of 363 subjects who had sexual intercourse with non-regular female sex partners and/or female sex workers in the past six months were selected. Logistic regression models were fitted for data analysis. About 16.5% of participants reported having used HIV testing in their lifetime and 12.7% for HIVST. Among the participants, 25.6% and 23.7% intended to take up any type of HIV testing and HIVST in the next six months, respectively. Significant factors associated with the behavioral intention to take up HIV testing and HIVST included individual-level factors based of the Health Belief Model (e.g., perceived benefit, perceived cue to action, perceived self-efficacy) and interpersonal-level factors (e.g., frequency of exposure to health-related content or HIV and STI-related content on short video apps). This study provided practical implications for designing interventions to increase the uptake of HIV testing and HIVST among migrant workers.

Mobility and HIV care engagement: a research agenda

INTRODUCTION

Mobility is common and an essential livelihood strategy in sub-Saharan Africa (SSA). Mobile people suffer worse outcomes at every stage of the HIV care cascade compared to non-mobile populations. Definitions of mobility vary widely, and research on the role of temporary mobility (as opposed to permanent migration) in HIV treatment outcomes is often lacking. In this article, we review the current landscape of mobility and HIV care research to identify what is already known, gaps in the literature, and recommendations for future research.

DISCUSSION

Mobility in SSA is closely linked to income generation, though caregiving, climate change and violence also contribute to the need to move. Mobility is likely to increase in the coming decades, both due to permanent migration and increased temporary mobility, which is likely much more common. We outline three central questions regarding mobility and HIV treatment outcomes in SSA. First, it is unclear what aspects of mobility matter most for HIV care outcomes and if high-risk mobility can be identified or predicted, which is necessary to facilitate targeted interventions for mobile populations. Second, it is unclear what groups are most vulnerable to mobility-associated treatment interruption and other adverse outcomes. And third, it is unclear what interventions can improve HIV treatment outcomes for mobile populations.

CONCLUSIONS

Mobility is essential for people living with HIV in SSA. HIV treatment programmes and broader health systems must understand and adapt to human mobility, both to promote the rights and welfare of mobile people and to end the HIV pandemic.

Screening of Schistosomiasis, Strongyloidiasis and Sexually Transmitted Infections in Nigerian Female Sex Workers Living in Rome

BACKGROUND

Female Sex Workers (FSWs) are at high risk for acquisition and transmission of sexually transmission infections (STIs). Although several studies investigated the diffusion of STIs in this population, none of them investigated the occurrence of helminth infections in FSW coming from endemic regions. This study aims to assess the prevalence of STIs and helminth infections in a cohort of FSWs.

METHOD

authors conducted a prevalent, observational, and descriptive study on 97 Nigerian FSWs aged 17 to 52 years from January to December 2020.

RESULTS

a total of 97 FSWs were recruited. Of these, only 82 had completed screening for hepatitis B, C, syphilis, and HIV, while all 97 were screened for schistosomiasis and strongyloidiasis. The prevalence of STIs among FSWs in Rome was lower than in other European countries. The overall prevalence of HIV and HBsAg were 1.2%, (1/82) and 2.4% (2/82), respectively, while no case of hepatitis C and syphilis was found. Regarding parasitological screening, the overall prevalence of schistosoma species was 4.1% (4/97) while 5.15% (5/97) were positive for strongyloidiasis.

CONCLUSIONS

our study shows a low prevalence of STIs in Nigerian FSWs except for Hepatitis B and a higher prevalence of schistosomiasis and strongyloidiasis. The permanent monitoring of STI and parasitic infections in sex workers coming from Africa is strongly warranted, especially for hepatitis B, schistosomiasis and strongyloidiasis, to allow a timely diagnosis and treatment, and to plan preventive strategies.

Protection or police harassment? Impacts of punitive policing, discrimination, and racial profiling under end-demand laws among im/migrant sex workers in Metro Vancouver

In 2014, Canada implemented end-demand sex work legislation which leaves the sale of sex under some circumstances legal. However, immigration policies based on discourses positioning sex work as exploitation and migration as trafficking continue to criminalize many im/migrant sex workers. Despite community reports of punitive policing, limited research has explored how police interactions with im/migrant sex workers have impacted labour conditions since this legislative shift. As part of a longstanding community-based Vancouver study, we drew on the conceptual framework of slow violence to analyze 20 in-depth interviews with sex workers born outside Canada. Despite rhetoric positioning im/migrant sex workers as victims deserving protection, participants described experiences of punitive, racialized, and stigmatizing police treatment. Fear of being 'outed' as a sex worker and living with precarious immigration status undermined participants' ability to seek police protections; yet when they did seek assistance after experiencing violence/theft, police were unsupportive or discriminatory. Our findings suggest that policies depicting im/migrant sex workers as victims act not to protect them, but to justify targeted repressive, racist policing that severely undermines women's occupational safety. Our results illustrate the harms of policies conflating sex work with trafficking; demonstrate the inherent opposition between legislative aims to protect those who sell sexual services and to abolish the sex industry; and interrogate who the state affirms as a deserving victim. The full decriminalization of sex work, removal of prohibitions on sex work among im/migrants, and community-led alternatives to the criminal justice system are urgently needed to uphold im/migrant sex workers' labour rights.

Perceptions of Health Needs among Venezuelan Women Crossing the Border in Northern Chile during the COVID-19 Pandemic

In parallel to the COVID-19 pandemic, Chile has experienced a significant influx of international migrants, many of whom are Venezuelan women who have entered the country through unauthorized crossing points. In this context, gender and migration intersect as the social determinants of health, leading to their experiencing a range of adverse events. This poses important challenges in terms of short- and long-term health outcomes, the social determinants of health, and access to healthcare. This study aims at describing Venezuelan women's perceptions of their health needs as they migrate to Chile via an unauthorized crossing point, with a focus on adverse events throughout the migration cycle, self-reported health needs, and responses. A qualitative case study was carried out with 22 participants in the Antofagasta region of Chile, including Venezuelan migrant women, healthcare professionals, and social workers from the public healthcare system, stakeholders from non-governmental and international organizations, and local government officials. The semi-structured, individual interviews were analyzed thematically. The results show that Venezuelan women face a range of adverse events throughout the migration cycle. The perceived health needs that are reported are sometimes linked to these adverse events or existed prior to migration and were exacerbated throughout the migratory cycle. Addressing these physical and mental health needs is essential for short- and long-term individual and public health; however, despite substantial efforts to ameliorate the situation, persisting gaps in access to care are reported.

Effect of police enforcement and extreme social inequalities on violence and mental health among women who sell sex: findings from a cohort study in London, UK

OBJECTIVES

To examine legal and social determinants of violence, anxiety/depression among sex workers.

METHODS

A participatory prospective cohort study among women (inclusive of transgender) ≥18 years, selling sex in the last 3 months in London between 2018 and 2019. We used logistic generalised estimating equation models to measure associations between structural factors on recent (6 months) violence from clients or others (local residents, strangers), depression/anxiety (Patient Health Questionnaire-4).

RESULTS

197 sex workers were recruited (96% cisgender-women; 46% street-based; 54% off-street) and 60% completed a follow-up questionnaire. Street-based sex workers experienced greater inequalities compared with off-street in relation to recent violence from clients (73% vs 36%); police (42% vs 7%); intimate partner violence (IPV) (56% vs 18%) and others (67% vs 17%), as well as homelessness (65% vs 7%) and recent law enforcement (87% vs 9%). Prevalence of any STI was 17.5% (17/97). For street-based sex workers, recent arrest was associated with violence from others (adjusted OR (aOR) 2.77; 95% CI 1.11 to 6.94) and displacement by police was associated with client violence (aOR 4.35; 95% CI 1.36 to 13.90). Financial difficulties were also associated with client violence (aOR 4.66; 95% CI 1.64 to 13.24). Disability (aOR 3.85; 95% CI 1.49 to 9.95) and client violence (aOR 2.55; 95% CI 1.10 to 5.91) were associated with anxiety/depression. For off-street sex workers, financial difficulties (aOR 3.66; 95% CI 1.64 to 8.18), unstable residency (aOR 3.19; 95% CI 1.36 to 7.49), IPV (aOR 3.77; 95% CI 1.30 to 11.00) and alcohol/drug use were associated with client violence (aOR 3.16; 95% CI 1.26 to 7.92), while always screening and refusing clients was protective (aOR 0.36; 95% CI 0.15 to 0.87). Disability (aOR 5.83; 95% CI 2.34 to 14.51), unmet mental health needs (aOR 3.08; 95% CI 1.15 to 8.23) and past eviction (aOR 3.99; 95% CI 1.23 to 12.92) were associated with anxiety/depression.

CONCLUSIONS

Violence, anxiety/depression are linked to poverty, unstable housing and police enforcement. We need to modify laws to allow sex workers to work safely and increase availability of housing and mental health services.

No increased HIV risk in general population near sex work sites: a nationally representative cross-sectional study in Zimbabwe

Objectives

Sex work sites have been hypothesised to be at the root of the observed heterogeneity in HIV prevalence in sub‐Saharan Africa. We determined if proximity to sex work sites is associated with HIV prevalence among the general population in Zimbabwe, a country with one of the highest HIV prevalence in the world.

Methods

In this cross‐sectional study we use a unique combination of nationally representative geolocated individual‐level data from 16,121 adults (age 15–49 years) from 400 sample locations and the locations of 55 sex work sites throughout Zimbabwe; covering an estimated 95% of all female sex workers (FSWs). We calculated the shortest distance by road from each survey sample location to the nearest sex work site, for all sites and by type of sex work site, and conducted univariate and multivariate multilevel logistic regressions to determine the association between distance to sex work sites and HIV seropositivity, controlling for age, sex, male circumcision status, number of lifetime sex partners, being a FSW client or being a stable partner of an FSW client.

Results

We found no significant association between HIV seroprevalence and proximity to the nearest sex work site among the general population in Zimbabwe, regardless of which type of site is closest (city site adjusted odds ratio [aOR] 1.010 [95% confidence interval {CI} 0.992–1.028]; economic growth point site aOR 0.982 [95% CI 0.962–1.002]; international site aOR 0.995 [95% CI 0.979–1.012]; seasonal site aOR 0.987 [95% CI 0.968–1.006] and transport site aOR 1.007 [95% CI 0.987–1.028]). Individual‐level indicators of sex work were significantly associated with HIV seropositivity: being an FSW client (aOR 1.445 [95% CI 1.188–1.745]); nine or more partners versus having one to three lifetime partners (aOR 2.072 [95% CI 1.654–2.596]).

Conclusions

Sex work sites do not seem to directly affect HIV prevalence among the general population in surrounding areas. Prevention and control interventions for HIV at these locations should primarily focus on sex workers and their clients, with special emphasis on including and retaining mobile sex workers and clients into services.

Migration and Mobility: Correlates of Recent HIV Testing Among Substance Using Female Sex Workers at the Mexico-Guatemala Border

The goal of this paper is to determine the association between traveling to engage in sex work in another country and recent access to HIV testing among substance-using female sex workers (FSWs) in the Mexico-Guatemala border region. From 2012 to 2015, through modified time-location sampling and peer referral, 255 FSWs were recruited at Mexico's southern border. Participants completed questionnaires on sociodemographics, migration and mobility experiences, work environment factors, and substance use. A conceptual framework, as depicted by a directed acyclic graph (DAG), guided our analysis. Crude and adjusted logistic regression models were used to evaluate the relationships between mobility experiences and HIV testing in the past year. Overall HIV testing was low (41%); after considering relevant covariates (i.e., interaction with health services and organizations, and sex work characteristics) traveling to engage in sex work in another country was found to be positively associated with HIV testing in the past year. Future efforts need to consider voluntary and non-stigmatizing prevention HIV services and focus on reaching out to less mobile women.

Determinants and Inequities in Sexual and Reproductive Health (SRH) Care Access Among Im/Migrant Women in Canada: Findings of a Comprehensive Review (2008-2018)

Given growing concerns of im/migrant women's access to sexual and reproductive health (SRH) services, we aimed to (1) describe inequities and determinants of their engagement with SRH services in Canada; and (2) understand their lived experiences of barriers and facilitators to healthcare. Using a comprehensive review methodology, we searched the quantitative and qualitative peer-reviewed literature of im/migrant women's access to SRH care in Canada from 2008 to 2018. Of 782 studies, 38 met inclusion criteria. Ontario (n = 18), British Columbia (n = 6), and Alberta (n = 6) were primary settings represented. Studies focused primarily on maternity care (n = 20) and sexual health screenings (n = 12). Determinants included health system navigation and service information; experiences with health personnel; culturally safe and language-specific care; social isolation and support; immigration-specific factors; discrimination and racialization; and gender and power relations. There is a need for research that compares experiences across diverse groups of racialized im/migrants and a broader range of SRH services to inform responsive, equity-focused programs and policies.

Mapping Workplace Neighborhood Mobility Among Sex Workers in an Urban Canadian Setting: Results of a Community-Based Spatial Epidemiological Study From 2010-2016

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.

Structural determinants of HIV/STI prevalence, HIV/STI/sexual and reproductive health access, and condom use among immigrant sex workers globally

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.

Shan Migrant Sex Workers Living with HIV Who Remain Active in Sexual Entertainment Venues in Chiang Mai, Thailand

Migrant female sex workers (MFSW) are at a high and increasing risk of HIV infection and may also be a source of transmission. In Northern Thailand, most MSFW are Shan ethnic nationals from Myanmar. This study aims to understand how the risks of HIV infection and transmission are perceived and acted upon by Shan MFSW living with HIV who remain active in sex work. The paper employs a narrative approach, offering insight into the lives of eight Shan MFSW living with HIV in Chiang Mai, Thailand. Their risk behaviors are examined, from when they first entered sex work through to becoming HIV-positive and adopting antiretroviral treatment, as well as the reasons for continuing sex work. The findings reveal several ways in which stigmatized identities and life conditions influence risk perceptions and behaviors of Shan MFSW. Shan MFSW exemplify biopolitical vulnerability as female migrants, and sex workers in addition to living with HIV and the constraints of poverty, and limited education and skills. Understanding the complexities in their life conditions suggested several ways to improve care for them.

HPV molecular detection from urine versus cervical samples: an alternative for HPV screening in indigenous populations

Background

Cervical cancer (CC) is the fourth leading cause of death from neoplasms in women and is caused by the human papilloma virus (HPV). Several methods have been developed for the screening of cervical lesions and HPV; however, some socio-cultural factors prevent women from undergoing gynecological inspection, which results in a higher risk of mortality from cervical cancer in certain population groups as indigenous communities. This study aimed to compare the concordance in HPV detection from urine and cervical samples, to propose an alternative to cervical scraping, which is commonly used in the cervical cancer screening.

Methodology

The DNA from cervical scrapings and urine samples was extracted using the proteinase K method followed by precipitation with alcohol, phenol andchloroform; a modification of the proteinase K method was developed in the management of urine sediment. Viral genotyping was performed using INNOLipa.

Results

The study population consisted of 108 patients from an indigenous population at southern Mexico, 32 without squamous intraepithelial lesions (NSIL) and 76 with low squamous intraepithelial lesions (LSIL). The majority of NSIL cervical scrapes were negative for HPV (90.63%), whereas more than half of LSIL cases were high-risk HPV positive (51.32%), followed by multiple infection by HR-HPV (17.11%), and multiple infection by LR- and HR-HPV (9.21%). No statistically significant relationship between the cytological diagnosis and the HPV genotypes detected in the urine samples was observed. A concordance of 68.27% for HPV positivity from urine and cervical samples was observed. Similarly, a concordance of 64.52% was observed in the grouping of HPVs by oncogenic risk. HR-HPV was detected in 71% of the urine samples from women with LSIL diagnosis, which suggests that HR-HPV detected in a urine sample could indicate the presence or risk of developing SIL.

Conclusion

HR-HPV detection in urine samples could be an initial approach for women at risk of developing LSIL and who, for cultural reasons, refuse to undergo a gynecological inspection.

Reducing Sexual and Reproductive Health Inequities Between Natives and Migrants: A Delphi Consensus for Sustainable Cross-Cultural Healthcare Pathways

The increasing number of international migrants (ranging from 153 million in 1990 to ~272 million in 2019) brought to attention the wide variation of national contexts concerning the policy measures to protect migrants' rights and ensuring their equal access to basic and essential services, namely in health. Sexual and Reproductive Health (SRH) is a key component to the overall health and quality of life and is impacted by power inequities inherent to society's institutions, environment, economics, and culture. In Portugal, guidelines for intervention in SRH are insufficient, a gap that is more pronounced with migrant populations due to the absence of culturally sensitive indicators to assess and monitor SRH. The aim of this work was 2-fold: to identify good practices in the SRH field, with a particular focus, whenever possible, on migrant populations, and to identify relevant and inclusive indicators to monitor SRH in Portugal. A Delphi panel (via online survey) with 66 experts (researchers, teachers, and health professionals) and 16 stakeholders (non-governmental organizations, civil society, and governmental organizations) was implemented in two rounds. Panelists were asked to state their level of agreement (5-point Likert-type scale) regarding four different SRH areas: Sexual Health, Reproductive Health, Social-Structural Factors, and Good Practices. Items were based on literature review and a World Café with 15 experts and stakeholders. Participation rate was 68% and response rate was 97% on the first round. From the initial list of 142 items, a total of 118 (83%) items were approved by consensus. Findings may provide extended opportunities for the healthcare system to engage in better informed decisions and more inclusive and integrative strategies regarding SRH, contributing to build political measures toward sexual and reproductive justice.

Intersections of Immigration and Sexual/Reproductive Health: An Umbrella Literature Review with a Focus on Health Equity

Identifying the opportunities and barriers of promoting and fulfilling the sexual health rights of migrants remains a challenge that requires systematic assessment. Such an assessment would include estimating the influence of acculturation processes on sexual and reproductive health, and mapping intersectional inequities that influence migrants’ sexual and reproductive health in comparison with the native population. The aim of this research was to locate, select, and critically assess/summarize scientific evidence regarding the social, cultural, and structural factors influencing migrants’ sexual and reproductive health outcomes in comparison with native population. An umbrella review of systematic reviews and/or meta-analyses, following preferred reporting items for systematic reviews and meta-analysis (PRISMA) standards was undertaken. Medline, Scopus, Web of Science, and the Cochrane Database of Systematic Reviews were searched from their start date until June 2019. The quality of the included articles was determined using the assessment of multiple systematic reviews tool (AMSTAR 2). From the 36 selected studies, only 12 compared migrant with native populations. Overall, the findings indicated that migrants tend to underuse maternal health services and have an increased risk of poor sexual and reproductive health outcomes. Specific intersectional inequities were identified and discussed.

Sexually Transmitted Infections and Associated Factors in Southeast Spain: A Retrospective Study from 2000 to 2014

The World Health Organization estimates that more than one million people acquire a Sexually Transmitted Infection (STI) every day, compromising quality of life, sexual and reproductive health, and the health of newborns and children. It is an objective of this study to identify the factors related to a Sexually Transmitted Infection diagnosis in the province of Granada (Spain), as well as those better predicting the risk of acquiring such infections. In this study, 678 cases were analyzed on a retrospective basis, which were treated at the Centre for Sexually Transmitted Diseases and Sexual Orientation in Granada, between 2000–2014. Descriptive statistics were applied, and by means of binary logistic regression, employing the forward stepwise-likelihood ratio, a predictive model was estimated for the risk of acquiring an STI. Sex, age, occupation, economic crisis period, drug use, number of days in which no condoms were used, number of sexual partners in the last month and in the last year, and number of subsequent visits and new subsequent episodes were associated with an STI diagnosis (p < 0.05). The risk of being diagnosed with an STI increased during the economic crisis period (OR: 1.88; 95%-CI: 1.28–2.76); during the economic crisis and if they were women (OR:2.35, 95%- CI: 1.24–4.44); and if they were women and immigrants (OR: 2.09; 95%- CI:1.22–3.57), while it decreased with age (OR: 0.97, 95%-CI: 0.95–0.98). Identification of the group comprised of immigrant women as an especially vulnerable group regarding the acquisition of an STI in our province reflects the need to incorporate the gender perspective into preventive strategies and STI primary health care.

HIV Infection and Risk Heightened Among Female Sex Workers Who Entered the Sex Trade as Adolescents in Guatemala

A dearth of empirical research exists on female sex workers in Central America who begin selling sex under age 18. Data were collected from adult female sex workers (N = 1216) sampled using census and modified time-location sampling in three urban centers of Guatemala. In adjusted analyses, female sex workers who entered the sex trade under age 16 years were more likely to be HIV positive (AOR = 4.6, 95% CI 1.6, 13.2), have not received HIV education in their first year of sex trade (AOR = 2.8, 95% CI 1.5, 5.5), have experienced violence to force commercial sex (AOR = 4.6, 95% CI 2.2, 9.8) and have not used condoms in their first month (AOR = 2.8, 95% CI 1.3, 6.1) , relative to those who entered as adults. An interaction between age at entry and foreign migration at entry was found for HIV risk. Efforts to prevent adolescent sex trade entry are needed and may also help to reduce HIV rates in Guatemala.

Prevalence and factors associated with hepatitis B and D virus infections among migrant sex workers in Chiangmai, Thailand: A cross-sectional study in 2019

OBJECTIVES

To determine the prevalence of hepatitis B surface antigen (HBsAg) and antibody to hepatitis delta virus (anti-HDV) and associated factors among migrant sex workers in Chiangmai, Thailand.

METHODS

This cross-sectional study was conducted at various sexual entertainment venues in Chiangmai, Thailand, in 2019. Consenting participants were interviewed using a questionnaire, and plasma was tested for hepatitis B virus (HBV) markers (DiaSorin, Italy) and anti-HDV antibody (DIA.PRO Diagnostic Bioprobes, Italy), if HBsAg-positive. Associations between HBsAg positivity or HDV antibody and potential factors were examined using univariable and multivariable logistic regression analysis.

RESULTS

A total of 396 migrant sex workers, half of them female, were recruited between February and September 2019. Their median age was 25 years (interquartile range 22-30 years) and 95% were Burmese. Overall, HBsAg prevalence was 11.4%; 8.1% in females and 14.7% in males (Chi-square, p = 0.040). One-third were still susceptible to HBV. No HBsAg-positive participants had anti-HDV antibodies. HBsAg positivity was associated with being male (adjusted odds ratio (aOR) 3.01, 95% confidence interval (CI) 1.25-7.68, p = 0.014), having attended school (aOR 4.50, 95% CI 1.26-15.98, p = 0.020), being separated/divorced/widowed (aOR 5.77, 95% CI 1.48-22.52, p = 0.012), and having unprotected sex (aOR 3.38, 95% CI 1.31-8.71, p = 0.012).

CONCLUSIONS

In this young population, higher HBsAg prevalence in males may be related to sexual transmission, indicating the need for HBV screening programs linked with HBV prevention and care.

Harms of Workplace Inspections for Im/Migrant Sex Workers in In-Call Establishments: Enhanced Barriers to Health Access in a Canadian Setting

Given shifting sex work criminalization and enforcement in Canada, this study examined worrying about workplace inspections by authorities amongst indoor sex workers in Vancouver (2014-2017). Data were drawn from a community-based prospective cohort of sex workers (AESHA). Bivariate and multivariable logistic regression were used to investigate factors associated with worry about inspections. 23.9% of participants experienced workplace inspections; 51.6% worried about inspections. In multivariable analyses, worrying about inspections was associated with recent im/migration [adjusted odds ratio (AOR) 3.13; 95% confidence interval (CI) 1.77-5.53], police harassment (AOR 3.49; 95% CI 1.92-6.34), and workplace violence (AOR 1.66, 95% CI 1.09-2.51). In a multivariable confounder model, worry was independently associated with barriers to health access (AOR 1.45, 95% CI 1.06-1.98). Im/migrant indoor workers are disproportionately impacted by concerns about workplace inspections, which was independently linked to enhanced barriers to health access. Current criminalization measures may exacerbate health inequities among im/migrant sex workers.

Exploring the Association Between Mobility and Access to HIV Services Among Female Sex Workers in Zimbabwe

Female sex workers (FSW) face structural barriers to HIV-service access, however the effect of their mobility is uncertain. Using cross-sectional data from 2839 FSW in 14 sites in Zimbabwe, we explored the association between mobility (number of trips, distance, duration) in the past 12 months and five HIV-service-access outcomes: exposure to community mobilisation, clinic attendance, HIV testing, antiretroviral treatment initiation, and viral suppression (< 1000 copies per mL). We used modified-Poisson regression, and natural-effects models to estimate how the effect of trip frequency was mediated by distance and duration away. Each additional trip in 12 months was associated with increased community-mobilisation-event attendance (adjusted RR 1.08, 95% CI 1.04-1.12) and attending clinic two-or-more times (adjusted RR 1.02, 95% CI 1.00-1.05). There was little evidence of any other associations, or of mediation. Our findings are consistent with literature that found the effects of mobility to vary by context and outcome. This is the first study to consider many FSW-mobility and HIV-service-access measures together. Future research on mobility and health-related behaviour should use a spectrum of measures.

Comparison of retention in observational cohorts and nested simulated HIV vaccine efficacy trials in the key populations in Uganda

Background

Outcomes in observational studies may not best estimate those expected in the HIV vaccine efficacy trials. We compared retention in Simulated HIV Vaccine Efficacy Trials (SiVETs) and observational cohorts drawn from two key populations in Uganda.

Methods

Two SiVETs were nested within two observational cohorts, one in Fisherfolk (FF) and another one in Female Sex Workers (FSW). Adult participants in each observational cohort were screened for enrolment into SiVETs. Those screened-out or not screened continued participation in the observational (non-SiVET) cohorts. SiVET participants were administered a licensed hepatitis B vaccine in a schedule that mimicked an actual HIV vaccine efficacy trial. Both cohorts were followed for 12 months and retention was assessed through dropout, defined as lost to follow up, being uncontactable, refusal to continue or missing the last study clinic visit. Dropout rates were compared using Poisson models giving rate ratios and 95% confidence intervals (95%CI).

Results

Out of 1525 participants (565 FF and 960 FSW), 572 (38%) were enrolled into SiVETs (282-FF and 290-FSW), and 953 (62%) remained in the non-SiVET cohorts. Overall, 326 (101 SiVET, 225 non-SiVET) dropped out in 1260 Person Years of Observation (PYO), a dropout rate of 25.9 /100 PYO (95%CI: 23.2–28.8); fewer dropped out in the SiVET cohorts (18.4, 95% CI: 15.1–22.4) than in the non-SiVET cohorts (31.6, 95% CI: 27.8–36.1), rate ratio (RR) =0.58, 95% CI: 0.46–0.73. In all cohorts, the dropout was more marked in FSW than in FF population. Duration lived in community was associated with dropout in both SiVETs and religion in both non-SiVET cohorts.

Conclusion

The rate of dropout was lower in SiVET compared to non-SiVET cohort. Though the difference in dropout between SiVET and non-SiVET was generally similar, the actual dropout rates were higher in the FSW population. Conduct of SiVETs in these key populations could mean that designing HIV Vaccine Efficacy Trials will benefit from lower dropout rate shown in SiVET than non-SiVET observational cohort.

Migration to the US among rural Puerto Ricans who inject drugs: influential factors, sources of support, and challenges for harm reduction interventions

BACKGROUND

While PWID of Puerto Rican origin have been migrating to the US for decades, the range of factors influencing their migration to the US and the resources they draw on to do so are not well understood. This is particularly true for rural Puerto Rican PWID, and the present study is the first empirical research to document migration patterns among this population. The specificities of their migration raise important challenges that need to be documented in order to implement more effective harm reduction policies at home (Puerto Rico) and abroad (US).

METHODS

This paper draws from data obtained employing a modified NHBS survey which was administered to (N =296) PWID in four rural municipalities of Puerto Rico with participants 18 years or older. The primary dependent variables for this paper are the number of times a person has lived in the continental US, and if they are planning on moving to the continental US in the future.

RESULTS

Findings suggest that 65% of the sample reported ever lived in the US and that 49% are planning on moving in the future. The number of times living in the US is associated with higher education and older age, but not with self-reported positive HIV or HCV statuses. Planning to move to the US is associated with knowing PWID who have moved or plan to move, negatively associated with age, and is not associated with HIV or HCV status. Around one third of those that lived in the US reported having some sort of support, with the majority receiving support from family sources. No participant received help to enter HIV/HCV treatment.

CONCLUSIONS

A multi-region approach to prevention is required to make a dent in curbing HIV/HCV transmission in this population. Understanding PWID migration patterns, risk behaviors, and health care needs in the US is now more important than ever as natural disasters prompted by human-made climate change will only increase in the future, raising demands not only for service providers but also harm reduction policies to cope with an increasing influx of "climate refugees" as PWID move across national borders.

Epidemiology of Treponema pallidum, Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and herpes simplex virus type 2 among female sex workers in the Middle East and North Africa: systematic review and meta-analytics

Background

The epidemiology of sexually transmitted infections (STIs) and the role of commercial heterosexual sex networks in driving STI transmission in the Middle East and North Africa (MENA) region remain largely unknown.

Objective

To characterize the epidemiology of Treponema pallidum (syphilis), Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and herpes simplex virus type 2 (HSV-2) among female sex workers (FSWs) in MENA using an in-depth quantitative assessment.

Methods

A systematic review on ten international, regional, and country-level databases was conducted, and reported following PRISMA guidelines. Pooled prevalences of current and/or ever infection for each STI were estimated using random-effects meta-analyses. Sources of between-study heterogeneity were investigated through random-effects meta-regressions.

Results

One T. pallidum incidence study and 144 STI prevalence studies were identified for 45 812 FSWs in 13 MENA countries. The pooled prevalence of current infection was 12.7% (95% confidence interval (CI) = 8.5%-17.7%) for T. pallidum, 14.4% (95% CI = 8.2%-22.0%) for C. trachomatis, 5.7% (95% CI = 3.5%-8.4%) for N. gonorrhoeae, and 7.1% (95% CI = 4.3%-10.5%) for T. vaginalis. The pooled prevalence of ever infection (seropositivity using antibody testing) was 12.8% (95% CI = 9.4%-16.6%) for T. pallidum, 80.3% (95% CI = 53.2%-97.6%) for C. trachomatis, and 23.7% (95% CI = 10.2%-40.4%) for HSV-2. The multivariable meta-regression for T. pallidum infection demonstrated strong subregional differences, with the Horn of Africa and North Africa showing, respectively 6-fold (adjusted odds ratio (AOR): 6.4; 95% CI = 2.5-16.7) and 5-fold (AOR = 5.0; 95% CI = 2.5-10.6) higher odds of infection than Eastern MENA. There was also strong evidence for declining T. pallidum odds of infection at 7% per year (AOR = 0.93; 95% CI = 0.88-0.98). Study-specific factors including diagnostic method, sample size, sampling methodology, and response rate, were not associated with syphilis infection. The multivariable model explained 48.5% of the variation in T. pallidum prevalence.

Conclusions

STI infection levels among FSWs in MENA are considerable, supporting a key role for commercial heterosexual sex networks in transmission dynamics, and highlighting the health needs of this neglected and vulnerable population. Syphilis prevalence in FSWs appears to have been declining for at least three decades. Gaps in evidence persist for multiple countries.

Impacts of im/migration experience on work stress among sex workers in Vancouver, Canada

OBJECTIVES

Despite the precarious and unsafe working conditions frequently experienced by sex workers (SWs) and im/migrant workers, there remains a paucity of research on work-related stress and links to duration of im/migration residency among SWs. This study analyzes the relationship between duration of residency and two dimensions of work stress among SWs in Metro Vancouver.

METHODS

Data were drawn from a longitudinal cohort of women SWs across Metro Vancouver (2010-2014). Multivariable confounder models with generalized estimating equations were developed to examine the independent effects of duration of residency on decision authority and job demands, after adjusting for confounders.

RESULTS

Of 545 SWs, 9.7% were recent im/migrants, 13.9% were long-term im/migrants, and 76.2% were non-migrants. In comparison to non-migrant SWs, recent (β coefficient - 1.02, 95% CI - 1.57 to - 0.47) and long-term im/migrants (β coefficient - 0.87, 95% CI - 1.36 to -0.38) faced decreased work stress related to job demands after adjustment for key confounders. Decision authority did not retain a significant independent association after adjusting for the same factors.

CONCLUSION

Job demands varied significantly by duration of residency. This may be explained by changing working conditions and experiences over the course of arrival and settlement among im/migrant SWs, as well as the role of formal work environments in supporting im/migrant SWs' well-being. Given high rates of work stress related to job demands and low decision authority among all SWs, decriminalization of sex work, improved occupational standards, and culturally sensitive interventions to promote collectivization and improved access to working conditions remain needed.

Characterising the relationship between migration and stigma affecting healthcare engagement among female sex workers in Lomé, Togo

Migration in West Africa is common and complicates the sustained delivery of comprehensive HIV care programmes for those with specific vulnerabilities to HIV, including female sex workers (FSW). This study evaluated whether migration potentiates the burden of stigma affecting FSW in Lomé, Togo. Respondent driven sampling identified 354 FSW who completed HIV testing and a questionnaire. Multivariable logistic regression was used to identify factors associated with stigma among FSW. Among study participants, 76.3% (270/354) were migrants, with 30.2% (107/354) reporting stigma. Migrant FSW were less likely to report stigma (aOR 0.40; 95% CI:0.22-0.73). FSW who had an abortion (aOR 3.40; 95% CI:1.79-6.30) and were tested for a sexually transmitted infection (STI) or HIV (aOR 2.03; 95% CI:1.16-3.55) were more likely to report stigma. Among FSW, 59.8% (211/353) disclosed selling sex to a health worker. Disclosure was more common among FSW who had been tested for an STI or HIV (36.7%; 77/210), or both (55.7%; 117/210), and resulted in an attenuated but significant association between STI or HIV testing and stigma, indicating that disclosure partially mediated the relationship. These results highlight the need to mitigate healthcare-related stigma affecting FSW, while also considering decentralised HIV testing approaches, including HIV self-testing.

What Works? Prevention and Control of Sexually Transmitted Infections and Blood-Borne Viruses in Migrants from Sub-Saharan Africa, Northeast Asia and Southeast Asia Living in High-Income Countries: A Systematic Review

Migration is a significant risk factor for the acquisition of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and other sexually transmitted infections (STIs). An increasing proportion of these infections in high-income countries, such as Australia, are among migrants moving from low and middle-income countries with a high prevalence of HIV, HBV and other STIs. This systematic review explored the prevention and control of HIV, HBV and other STIs in migrants (>18 years) from Southeast Asia, Northeast Asia and sub-Saharan Africa living in high-income countries with universal health care. This systematic review followed PRISMA guidelines and was registered with PROSPERO. Six academic databases were searched for articles published between 2002 and 2018. Sixteen peer-reviewed articles met the inclusion criteria, consisting of fourteen quantitative and two qualitative studies conducted in Australia, the Netherlands, Canada, Spain, Italy, and Germany. Three levels of interventions were identified: individual, community and structural interventions. Most studies addressed factors at an individual level; interventions were most commonly outreach testing for HIV, HBV and other STIs. Few studies addressed structural factors or demonstrated comprehensive evaluation of interventions. Limited population-specific findings could be determined. To prevent further transmission of HIV, HBV and other STIs, comprehensive public health approaches must consider the complex interactions between migration, health care system determinants, and broader socioeconomic and sociocultural factors.

Evidence or stereotype? Health inequalities and representations of sex workers in health publications in England

The health of sex workers is considerably influenced by their position in society and by the marginalisation and stigmatisation they face worldwide. They are frequently criminalised and labelled as deviant, disordered or 'vulnerable': stereotypes that simplify and misrepresent their realities. Sex work policies create social and structural barriers, creating dangerous work environments and exacerbating significant health inequalities. Health organisations and their policies play an important role in highlighting inequalities and guiding health systems in reducing them. In this article, we use a document analysis design to analyse how and when sex workers are depicted in policies and publications by English national health organisations: National Health Service (NHS) England, Public Health England and the National Institute for Health and Care Excellence, along with the UK Department of Health. We find that sex workers are largely absent in these documents and, when present, are depicted not using evidence, but simplistically with moralistic undertones. The dichotomous constructions found in these texts: vulnerable yet also criminal 'prostitute' reflect wider political and social constructions of sex working women. This not only obscures their realities but also homogenises, blames and stigmatises, ultimately doing the opposite of what these organisations purport to do: it damages their health and well-being.

Preventing sexually transmitted and blood borne infections (STBBIs) among sex workers: a critical review of the evidence on determinants and interventions in high-income countries

Background

Across diverse regions globally, sex workers continue to face a disproportionate burden of HIV and other sexually transmitted and blood borne infections (STBBIs). Evidence suggests that behavioural and biomedical interventions are only moderately successful in reducing STBBIs at the population level, leading to calls for increased structural and community-led interventions. Given that structural approaches to mitigating STBBI risk beyond HIV among sex workers in high-income settings remain poorly understood, this critical review aimed to provide a comprehensive synthesis of the global research and literature on determinants of HIV and other STBBIs and promising intervention practices for sex workers of all genders in high-income countries.

Methods

We searched for publications over the last decade (January 2005–March 2016) among sex workers (cis women, cis men, and trans individuals). Data obtained from quantitative peer-reviewed studies were triangulated with publicly available reports and qualitative/ethnographic research where quantitative evidence was limited.

Results

Research demonstrates consistent evidence of the direct and indirect impacts of structural factors (e.g., violence, stigma, criminalization, poor working conditions) on increasing risk for STBBIs among sex workers, further compounded by individual and interpersonal factors (e.g., mental health, substance use, unprotected sex). Sub-optimal access to health and STBBI prevention services remains concerning. Full decriminalization of sex work has been shown to have the largest potential to avert new infections in sex work, through reducing workplace violence and increasing access to safer workspaces. Promising practices and strategies that should be scaled-up and evaluated to prevent STBBIs are highlighted.

Conclusions

The high burden of STBBIs among sex workers across high-income settings is of major concern. This review uniquely contributes to our understanding of multilevel factors that potentiate and mitigate STBBI risk for sex workers of all genders. Research suggests that multipronged structural and community-led approaches are paramount to addressing STBBI burden, and are necessary to realizing health and human rights for sex workers. Given the heterogeneity of sex worker populations, and distinct vulnerabilities faced by cis men and trans sex workers, further research utilizing mixed-methods should be implemented to delineate the intersections of risk and ameliorate critical health inequalities.

Effect of ART scale-up and female migration intensity on risk of HIV acquisition: results from a population-based cohort in KwaZulu-Natal, South Africa

BACKGROUND

Despite increased antiretroviral therapy (ART) coverage, the incidence of HIV infection among women in rural South Africa remains high. While many socio-demographic and behavioral factors have been identified, the effect of female migration intensity on the risk of HIV acquisition before and after ART scale-up has not been evaluated in the country.

METHODS

We followed 13,315 female participants aged 15-49 who were HIV-uninfected at baseline and recorded their migration events between 2004 and 2015. Using a Cox proportional hazard model, we estimated the time to HIV acquisition among the women, adjusting for annual migration intensity (high: ≥2 events/year, moderate = 1 event/year, and low = 0 event/year) before and after ART scale-up in 2010.

RESULTS

1998 (15%) new HIV-infection events were recorded during the observation period. Overall, high migration intensity was associated with an increased HIV acquisition risk among women when compared with low migration intensity (HR = 2.88, 95% CI: 1.56-5.53). Among those with high migration intensity, the risk of HIV acquisition was significantly lower in the post-ART period compared to the pre-ART period, after controlling for key socio-demographic and behavioural covariates (aHR = 0.18, 95% CI 0.04-0.83).

CONCLUSIONS

Women who migrated frequently after ART scale-up had a significantly reduced HIV acquisition risk compared to those before its implementation. While this reduction is encouraging, women who migrate frequently remain at high risk of HIV acquisition. In the era of ART, there remains a critical need for public health interventions to reduce the risk of HIV acquisition in this highly vulnerable population.

Rising Chlamydia and Gonorrhoea Incidence and Associated Risk Factors Among Female Sex Workers in Australia: A Retrospective Cohort Study

BACKGROUND

Female sex workers in Australia have achieved some of the lowest documented prevalences of human immunodeficiency virus (HIV) and other sexually transmissible infections globally but rates overall are increasing in Australia and warrant closer investigation.

METHODS

We constructed a retrospective cohort using repeat testing data extracted from a network of 42 sexual health clinics. Poisson and Cox regression were used to determined trends in incidence and risk factors for HIV, chlamydia, gonorrhoea, and infectious syphilis among female sex workers.

RESULTS

From 2009 to 2015, 18,475 women reporting sex work attended a participating service. The overall incidence of urogenital chlamydia was 7.7/100 person years (PY), declining by 38% from 2009 to 2013 before increasing by 43% to 2015 (P < 0.001); anorectal chlamydia incidence was 0.6/100 PY, and pharyngeal was 1.9/100 PY, which increased significantly during the study period (P < 0.001, both). For gonorrhoea, the urogenital incidence was 1.4/100 PY, anorectal incidence was 0.3/100 PY, P < 0.001), and 3.6/100 PY for pharyngeal; urogenital incidence doubled during the study period, anorectal increased fivefold, and pharyngeal more than tripled (P < 0.001, all). Incidence of infectious syphilis was 0.4/100 PY, which remained stable from 2009 to 2015 (P = 0.09). There were seven incident infections of HIV among female sex workers (0.1/100 PY). Inconsistent condom use with private partners, higher number of private partner numbers, recent injecting drug use, younger age, and country of birth variously predicted sexually transmissible infections among female sex workers.

CONCLUSIONS

Although infectious syphilis and HIV remain uncommon in female sex workers attending Australian sexual health clinics, the increasing incidence of gonorrhoea across anatomical sites and increasing chlamydia after a period of decline demands enhanced health promotion initiatives.

Gender Differences in Violence and Other Human Rights Abuses Among Migrant Workers on the Thailand–Myanmar Border

We describe human rights violations against migrant workers at the Thailand–Myanmar border, and evaluate differences by gender and industry. This mixed methods study pairs key informant interviews ( n = 40) with a cross-sectional quantitative survey of migrant workers from Myanmar ( n = 589) recruited via respondent-driven sampling. Key informants described significant hazards during migration, including deception, theft, and physical and sexual abuse, the latter primarily for women. Quantitative results confirmed prevalent mistreatment and abuse, with significant gender differences, most notably women’s disproportionate burden of sexual abuse. Current evidence on the nature of experiences, and significant differences by gender, can position prevention and response programming.

Detecting spatial clusters of HIV and hepatitis coinfections

BACKGROUND

People with HIV infection in the United States are often affected by chronic viral hepatitis. These coinfected people with either HBV or HCV are at increased risk for serious, life-threatening complications. Coinfections with viral hepatitis may also complicate the delivery of anti-retroviral therapy (ART) by escalating the risk of drug-related hepatoxicity. According to the Centers for Disease Control and Prevention (CDC), approximately 10 percent of people with HIV in the United States also have HBV, and 25 percent also have HCV coinfection. With the advent of highly active antiretroviral therapy (HAART) and the increased life-expectancy of HIV patients, clinicians are more likely to be confronted with issues related to co-infection and the management challenges that they present, especially in resource-limited settings. The purpose of this analysis was to identify geographical clusters of HIV- (HBV/HCV) co-infection and compared to the geographical clusters of not co-infected using DC, Department of Health surveillance data. The results of the analysis will be used to target resources to areas at risk.

METHODS

HIV and Hepatitis surveillance data were matched among cases diagnosed between 1980 and 2016. HIV-hepatitis co-infected and the not co-infected spatial clusters were detected using discrete Poisson model. Kulldorff's spatial scan statistic method was implemented in the free software tool called SaTScan which has been widely adopted for detecting disease cluster. The analysis was conducted by tracts, but for visualization, ease of interpretation and assist in policy making the tract map was overlaid with the ward map using ArcGIS 10.5.1.

RESULTS

Between 1980 and 2016, there were 12,965 diagnosed cases of HIV, of which 2,316 HIV/Hepatitis matches were identified. Of the 2316 co-infected people living in DC, 25 percent (N = 590) of people had HBV, and 75 percent (N = 1,726) had HCV. Out of 12,965 diagnosed cases, remaining 10,649 did not have any co-infections (not co-infected). IDU (27.16 percent) and MSM (32.86 percent) were the highest mode of transmission for co-infected population. African-American were reported 83.64 percent (N = 1,937) among co-infection population. Three clusters were identified for both co-infected population in DC. The largest cluster radius for co-infected analysis covers wards 6, 7 and 8 as well as large parts of 2 and 5 (p < 0.001). Multiple clusters were identified for not co-infected population (p < 0.001). IDU (n = 450) was the highest mode of transmission for the co-infected clusters. For all clusters combined of not co-infected population highest mode of transmission were MSM (n = 2,534). This analysis also showed racial disparity, economic deprivation and lack of education were prominent in the co-infected clusters.

CONCLUSION

We identified locations of high risk clusters where enhanced hepatitis and HIV prevention, treatment, and care can help combat the epidemic. The clusters radius expands into the neighboring state of Maryland as well. The findings from this analysis will be used to target area based public health policy and healthcare interventions for HIV-hepatitis. It is recommended based on the analysis that needle exchange programs can successfully control new HIV infections as well as hepatitis co-infections.

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.

Bibliometric analysis of global migration health research in peer-reviewed literature (2000-2016)

BACKGROUND

The health of migrants has become an important issue in global health and foreign policy. Assessing the current status of research activity and identifying gaps in global migration health (GMH) is an important step in mapping the evidence-base and on advocating health needs of migrants and mobile populations. The aim of this study was to analyze globally published peer-reviewed literature in GMH.

METHODS

A bibliometric analysis methodology was used. The Scopus database was used to retrieve documents in peer-reviewed journals in GMH for the study period from 2000 to 2016. A group of experts in GMH developed the needed keywords and validated the final search strategy.

RESULTS

The number of retrieved documents was 21,457. Approximately one third (6878; 32.1%) of the retrieved documents were published in the last three years of the study period. In total, 5451 (25.4%) documents were about refugees and asylum seekers, while 1328 (6.2%) were about migrant workers, 440 (2.1%) were about international students, 679 (3.2%) were about victims of human trafficking/smuggling, 26 (0.1%) were about patients' mobility across international borders, and the remaining documents were about unspecified categories of migrants. The majority of the retrieved documents (10,086; 47.0%) were in psychosocial and mental health domain, while 2945 (13.7%) documents were in infectious diseases, 6819 (31.8%) documents were in health policy and systems, 2759 (12.8%) documents were in maternal and reproductive health, and 1918 (8.9%) were in non-communicable diseases. The contribution of authors and institutions in Asian countries, Latin America, Africa, Middle East, and Eastern European countries was low. Literature in GMH represents the perspectives of high-income migrant destination countries.

CONCLUSION

Our heat map of research output shows that despite the ever-growing prominence of human mobility across the globe, and Sustainable Development Goals of leaving no one behind, research output on migrants' health is not consistent with the global migration pattern. A stronger evidence base is needed to enable authorities to make evidence-informed decisions on migration health policy and practice. Research collaboration and networks should be encouraged to prioritize research in GMH.

The effect of mobility on HIV-related healthcare access and use for female sex workers: A systematic review

Female sex workers (FSW) experience a high HIV burden and are often mobile. FSW access to HIV-related healthcare is essential for equitable welfare and to reduce new HIV infections. We systematically reviewed the literature on mobility and HIV-related healthcare access and use among FSW. Outcome measures included: HIV/STI testing, STI treatment, PrEP (initiation or adherence), and ART (initiation or adherence). We summarised the results with a narrative synthesis. From 7417 non-duplicated citations, nine studies from Canada (3), Guatamala, Honduras (2), India, South Africa, and Vietnam were included. Only one of the studies was designed to address mobility and healthcare access, and only six reported adjusted effect estimates. Mobility was measured over four time-frames (from 'current' to 'ever'), as having lived or worked elsewhere or in another town/province/country. Three studies from Canada, Guatemala, and India found mobility associated with increased odds of poor initial access to healthcare (adjusted odds ratios (AOR) from 1.33, 95% CI 1.02, 1.75, to 2.27, 95% CI 1.09, 4.76), and one from Vietnam found no association (odds ratio (OR): 0.92, 95% CI 0.65, 1.28). The study from South Africa found no association with initiating ART (risk ratio: 0.86, 95% CI 0.65, 1.14). Two studies from Canada and Honduras found increased odds of ART interruption (AOR 2.74, 95% CI 0.89, 8.42; 5.19, 95% CI 1.38, 19.56), while two other studies from Canada and Honduras found no association with detectable viral load (OR 0.84, 95% CI 0.08, 8.33; AOR 0.79, 95% CI 0.41, 1.69). We found that mobility is associated with reduced initial healthcare access and interruption of ART, consistent with literature from the general population. Discordance between effects on adherence and viral load may be due to measurement of mobility. Future research should carefully construct measures of mobility and consider a range of HIV-related healthcare outcomes.

Behavioural interventions promoting condom use among female sex workers in sub-Saharan Africa: a systematic review

The objective of this review was to provide an overview of behavioural interventions promoting condom use amongst female sex workers (FSW) in sub-Saharan Africa. A search of four electronic bibliographic databases from 1990 to September 2016 was carried out. The search was limited to articles published in English. Studies which evaluated behavioural interventions to increase condom use among FSWs were selected and reviewed. Data were extracted on effectiveness, condom use, intervention content, and process outcomes. A total of 20 eligible articles describing 18 interventions in sub-Saharan Africa on HIV prevention with condom use as an outcome measure were identified. Most of the behavioural interventions incorporated a combination of approaches: health education by peers, health workers and project staff, and activities by brothel owners and brothel managers. Most studies showed effectiveness of these interventions on condom use with paying clients. Five studies measuring condom use with regular non-paying partners recorded less consistent condom use with these partners. This review illustrates the existence of sufficient evidence showing the effectiveness of behavioural interventions targeting correct and consistent condom use by FSWs.

Influence of indoor work environments on health, safety, and human rights among migrant sex workers at the Guatemala-Mexico Border: a call for occupational health and safety interventions

BACKGROUND

Migrant women are over-represented in the sex industry, and migrant sex workers experience disproportionate health inequities, including those related to health access, HIV and sexually transmitted infections (STIs), and violence. Despite calls for occupational sex work interventions situated in labour rights frameworks, there remains a paucity of evidence pertaining to migrant sex workers' needs and realities, particularly within Mexico and Central America. This study investigated migrant sex workers' narratives regarding the ways in which structural features of work environments shape vulnerability and agency related to HIV/STI prevention and violence at the Guatemala-Mexico border.

METHODS

Drawing on theoretical perspectives on risk environments and structural determinants of HIV in sex work, we analyzed in-depth interviews, focus groups, and ethnographic fieldwork conducted with 39 migrant sex workers in indoor work environments between 2012 and 2015 in Tecún Umán, Guatemala.

RESULTS

Participant narratives revealed the following intersecting themes to be most closely linked to safety and agency to engage in HIV/STI prevention: physical features of indoor work environments (e.g., physical layout of venue, proximity to peers and third parties); social norms and practices for alcohol use within the workplace; the existence and nature of management practices and policies on health and safety practices; and economic influences relating to control over earnings and clients. Across work environments, health and safety were greatly shaped by human rights concerns stemming from workplace interactions with police, immigration authorities, and health authorities.

CONCLUSIONS

Physical isolation, establishment norms promoting alcohol use, restricted economic agency, and human rights violations related to sex work policies and immigration enforcement were found to exacerbate risks. However, some establishment policies and practices promoted 'enabling environments' for health and safety, supporting HIV/STI prevention, economic agency, and protection from violence and exploitation; these practices and policies were especially crucial for recent migrants. Policy reforms and structural workplace interventions tailored to migrant sex workers' needs are recommended to promote improved working conditions and migrant sex workers' health, safety, and human rights.

Health Services Use and HIV Prevalence Among Migrant and National Female Sex Workers in Portugal: Are We Providing the Services Needed?

This cross-sectional bio-behavioral survey conducted with 853 female sex workers (FSW) aimed to examine differences in use of HIV health services, testing and prevalence among migrant and national FSW. A quarter of undocumented FSW had never used National Health Service (NHS) and 15 % never tested for HIV, significantly more than nationals (p < 0.001 and p = 0.024, respectively). HIV infection was self-reported by 11.9 % of nationals, 1.8 % of documented and 0.8 % of undocumented migrants (p < 0.001). The HIV rapid test was reactive in 13.6 % of undocumented, 8.0 % of nationals and 2.3 % of documented. A higher proportion of migrants were unaware of their positive serostatus compared to nationals. Ever had HIV testing was less likely among undocumented, who never used the NHS and who didn't know where to go if suspected being HIV-infected. Promoting early diagnosis with linkage to care among migrant FSW should be supported, while developing health services better tailored to their needs.

First HIV prevalence estimates of a representative sample of adult sub-Saharan African migrants in a European city. Results of a community-based, cross-sectional study in Antwerp, Belgium

Introduction

While sub-Saharan African migrants are the second largest group affected by HIV in Europe, sound HIV prevalence estimates based on representative samples of these heterogeneous communities are lacking. Such data are needed to inform prevention and public health policy.

Methods

This community-based, cross-sectional study combined oral fluid HIV testing with an electronic behavioral survey. Adopting a two-stage time location sampling HIV prevalence estimates for a representative sample of adult sub-Saharan African migrants in Antwerp, Belgium were obtained. Sample proportions and estimated adjusted population proportions were calculated for all variables. Univariable and multivariable logistic regression analysis explored factors independently associated with HIV infection.

Results

Between December 2013 and October 2014, 744 sub-Saharan African migrants were included (37% women). A substantial proportion was socially, legally and economically vulnerable: 21% were probably of undocumented status, 63% had financial problems in the last year and 9% lacked stable housing. Sexual networks were mostly African and crossed national borders, i.e. sexual encounters during travels within Europa and Africa. Concurrency is common, 34% of those in a stable relationship had a partner on the side in the last year. HIV prevalence was 5.9%(95%CI:3.4%-10.1%) among women and 4.2% (95%CI:1.6%-10.6%) among men. Although high lifetime HIV testing was reported at community level (73%), 65.2% (CI95%:32.4%-88.0%) of sub-Saharan African migrants were possibly undiagnosed. Being 45 years or older, unprotected sex when travelling within Europe in the last year, high intentions to use condoms, being unaware of their last sexual partners’ HIV status, recent HIV testing and not having encountered partner violence in the last year were independently associated with HIV infection in multivariable logical regression. In univariable analysis, HIV infection was additionally associated to unemployment.

Conclusions

This is the first HIV prevalence study among adult sub-Saharan African migrants resettling in a European city based on a representative sample. HIV prevalence was high and could potentially increase further due to the high number of people with an undiagnosed HIV infection, social vulnerability, high levels of concurrency and mainly African sexual networks. Given this population’s mobility, an aligned European combination prevention approach addressing these determinants is urgently needed.

Recent im/migration to Canada linked to unmet health needs among sex workers in Vancouver, Canada: Findings of a longitudinal study

Despite universal health care in Canada, sex workers (SWs) and im/migrants experience suboptimal health care access. In this analysis, we examined the correlates of unmet health needs among SWs in Metro Vancouver over time. Data from a longitudinal cohort of women SWs (An Evaluation of Sex Workers Health Access [AESHA]) were used. Of 742 SWs, 25.5% reported unmet health needs at least once over the 4-year study period. In multivariable logistic regression using generalized estimating equations, recent im/migration had the strongest impact on unmet health needs; long-term im/migration, policing, and trauma were also important determinants. Legal and social supports to promote im/migrant SWs' access to health care are recommended.

Structural Determinants of Health among Im/Migrants in the Indoor Sex Industry: Experiences of Workers and Managers/Owners in Metropolitan Vancouver

Background

Globally, im/migrant women are overrepresented in the sex industry and experience disproportionate health inequities. Despite evidence that the health impacts of migration may vary according to the timing and stage of migration (e.g., early arrival vs. long-term migration), limited evidence exists regarding social and structural determinants of health across different stages of migration, especially among im/migrants engaged in sex work. Our aim was to describe and analyze the evolving social and structural determinants of health and safety across the arrival and settlement process for im/migrants in the indoor sex industry.

Methods

We analyzed qualitative interviews conducted with 44 im/migrant sex workers and managers/owners working in indoor sex establishments (e.g., massage parlours, micro-brothels) in Metropolitan Vancouver, Canada in 2011; quantitative data from AESHA, a larger community-based cohort, were used to describe socio-demographic and social and structural characteristics of im/migrant sex workers.

Results

Based on quantitative data among 198 im/migrant workers in AESHA, 78.3% were Chinese-born, the median duration in Canada was 6 years, and most (86.4%) serviced clients in formal indoor establishments. Qualitative narratives revealed diverse pathways into sex work upon arrival to Canada, including language barriers to conventional labour markets and the higher pay and relative flexibility of sex work. Once engaged in sex work, fear associated with police raids (e.g., immigration concerns, sex work disclosure) and language barriers to sexual negotiation and health, social and legal supports posed pervasive challenges to health, safety and human rights during long-term settlement in Canada.

Conclusions

Findings highlight the critical influences of criminalization, language barriers, and stigma and discrimination related to sex work and im/migrant status in shaping occupational health and safety for im/migrants engaged in sex work. Interventions and policy reforms that emphasize human rights and occupational health are needed to promote health and wellbeing across the arrival and settlement process.

Prevalence of sexually transmitted infections among Tanzanian migrants: a cross-sectional study

For the many millions of migrants, mobility creates vulnerabilities and elevates risk for sexually transmitted infections (STIs). We document, among Tanzanian agricultural plantation residents, migrant characteristics and test associations between migrant status and prevalent STI (HSV-2, syphilis, and HIV). From 623 plantation resident participants, we limit this analysis to participants about whom we know migration status (migrants n = 242, non-migrants n = 291). We collected behavioral data via audio-computer assisted self-interview survey, and clinical data via STI testing. We used multivariate Poisson regression models, stratified by gender and controlling for behavioral risk factors, to measure associations between migrant status and STI. In men, HIV prevalence was 9% for migrants, and 6% for non-migrants. HSV-2 prevalence was 57% for migrants, and 32% for non-migrants. Syphilis prevalence was 12% for migrants, and 3% for non-migrants. Among women, there were few differences in STI prevalence by migrant status: prevalence of HIV was 6% vs. 5% (migrants vs. non-migrants); HSV-2 prevalence was 68% vs. 65%; and syphilis prevalence was 11% vs. 8%. Being a male migrant was significantly associated with increased prevalence of any STI after controlling for sociodemographic and behavioral characteristics (APR = 1.53, 95% CI 1.23-5.25). Migrant women did not have increased prevalence of STI as compared to non-migrant women (APR = 1.03, 95% CI 0.85-1.24). Amongst Tanzanian agricultural workers, male migrants experienced elevated risk for prevalent STI as compared to male non-migrants. We suggest structural interventions to reduce risks associated with migration, especially in male migrants, including workplace-based STI prevention programs, and connecting migrants to resources and support within new communities. The key messages are: migrant men experience significantly elevated risk for prevalent STI, above and beyond sociodemographic and behavioral risk factors, as compared to their non-migrant peers; women in this Tanzanian agricultural plantation community overall had higher prevalence of some STIs than men, migrant women had similar STI risk as non-migrant women; and migration for work, an economic strategy for millions, also creates vulnerabilities, so workplace-based STI prevention programs and connecting migrants to community resources are essential.

Condoms and sexual health education as evidence: impact of criminalization of in-call venues and managers on migrant sex workers access to HIV/STI prevention in a Canadian setting

Background

Despite a large body of evidence globally demonstrating that the criminalization of sex workers increases HIV/STI risks, we know far less about the impact of criminalization and policing of managers and in-call establishments on HIV/STI prevention among sex workers, and even less so among migrant sex workers.

Methods

Analysis draws on ethnographic fieldwork and 46 qualitative interviews with migrant sex workers, managers and business owners of in-call sex work venues in Metro Vancouver, Canada.

Results

The criminalization of in-call venues and third parties explicitly limits sex workers’ access to HIV/STI prevention, including manager restrictions on condoms and limited onsite access to sexual health information and HIV/STI testing. With limited labour protections and socio-cultural barriers, criminalization and policing undermine the health and human rights of migrant sex workers working in –call venues.

Conclusions

This research supports growing evidence-based calls for decriminalization of sex work, including the removal of criminal sanctions targeting third parties and in-call venues, alongside programs and policies that better protect the working conditions of migrant sex workers as critical to HIV/STI prevention and human rights.

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.

Implementation and Operational Research: Cohort Analysis of Program Data to Estimate HIV Incidence and Uptake of HIV-Related Services Among Female Sex Workers in Zimbabwe, 2009-2014

BACKGROUND

HIV epidemiology and intervention uptake among female sex workers (FSW) in sub-Saharan Africa remain poorly understood. Data from outreach programs are a neglected resource.

METHODS

Analysis of data from FSW consultations with Zimbabwe's National Sex Work program, 2009-2014. At each visit, data were collected on sociodemographic characteristics, HIV testing history, HIV tests conducted by the program and antiretroviral (ARV) history. Characteristics at first visit and longitudinal data on program engagement, repeat HIV testing, and HIV seroconversion were analyzed using a cohort approach.

RESULTS

Data were available for 13,360 women, 31,389 visits, 14,579 reported HIV tests, 2750 tests undertaken by the program, and 2387 reported ARV treatment initiations. At first visit, 72% of FSW had tested for HIV; 50% of these reported being HIV positive. Among HIV-positive women, 41% reported being on ARV. 56% of FSW attended the program only once. FSW who had not previously had an HIV-positive test had been tested within the last 6 months 27% of the time during follow-up. After testing HIV positive, women started on ARV at a rate of 23/100 person years of follow-up. Among those with 2 or more HIV tests, the HIV seroconversion rate was 9.8/100 person years of follow-up (95% confidence interval: 7.1 to 15.9).

CONCLUSIONS

Individual-level outreach program data can be used to estimate HIV incidence and intervention uptake among FSW in Zimbabwe. Current data suggest very high HIV prevalence and incidence among this group and help identify areas for program improvement. Further methodological validation is required.
