Global epidemiology of HIV among female sex workers: influence of structural determinants

Accounting for historical injustices in mathematical models of infectious disease transmission: An analytic overview

Differences in infectious disease risk, acquisition, and severity arise from intersectional systems of oppression and resulting historical injustices that shape individual behavior and circumstance. We define historical injustices as distinct events and policies that arise out of intersectional systems of oppression. We view historical injustices as a medium through which structural forces affect health both directly and indirectly, and are thus important to study in the context of infectious disease disparities. In this critical analysis we aim to highlight the importance of incorporating historical injustices into mathematical models of infectious disease transmission and provide context on the methodologies to do so. We offer two illustrations of elements of model building (i.e., parameterization, validation and calibration) that can allow for a better understanding of health disparities in infectious disease outcomes. Mathematical models that do not recognize the historical forces that underlie infectious disease dynamics inevitably lead to the individualization of our focus and the recommendation of untenable individual-behavioral prescriptions to address the burden of infectious disease.

Prevalence and Social-Structural Correlates of Gender-Based Violence Against Women Living With HIV in Metro Vancouver, Canada

Violence experienced by cisgender (cis) and gender minority women living with HIV is known to be high. More work is needed to better understand how to support women living with HIV who have experienced violence. The objectives of this study are therefore to identify the prevalence and correlates of violence by any perpetrator among women living with HIV in a Canadian setting. Data were drawn from 9 years (January, 2010 to February, 2019) of a longitudinal community-based open cohort study of 350+ cis and trans women living with HIV who were living and/or accessed care in Metro Vancouver, Canada (Sexual Health and HIV/AIDS: Women's Longitudinal Needs Assessment "SHAWNA"). Participants completed baseline and biannual follow-up interviews. Bivariate and multivariable logistic regression with generalized estimating equations (GEE) were performed to identify correlates of recent (last 6 months) violence (physical and/or sexual) by any perpetrator. Adjusted odds ratios (AOR) and 95% confidence intervals (95% CIs) are presented. At baseline, prevalence of violence was high: 95.5% (recent = 19.4%) of participants reported lifetime physical and/or sexual violence, 94.8% (recent = 17.9%) reported lifetime physical violence, and 84.5% (recent = 5.7%) reported lifetime sexual violence. In multivariable logistic regression with GEE, the following variables were associated with higher odds of recent physical/sexual violence: youth (<30 years) (AOR: 1.60, 95% CI [1.15, 2.22]), recent unstable housing/homelessness (AOR: 1.96, 95% CI [1.30, 2.97]), recent food insecurity (AOR: 1.57, 95% CI [1.13, 2.17]), recent incarceration (AOR: 1.85, 95% CI [1.18, 2.91]), recent opioid use (AOR: 1.38, 95% CI [1.04, 1.82]), recent stimulant use (AOR: 2.48, 95% CI [1.72, 3.56]), and lifetime HIV status disclosure without consent (AOR: 1.59, 95% CI [1.13, 2.24]). Trauma- and violence-informed (TVI) policies that include a focus on confidentiality and safe disclosure practices should be integrated into existing housing, incarceration, and harm reduction programs, and HIV care and practice for women living with HIV. Programs and policies that address high levels of violence remain critical.

Self-Reported Adherence to Antiretroviral Therapy (ART) Among Women Engaged in Commercial Sex Work in Southern Uganda

We examined the correlates of self-reported adherence to antiretroviral therapy (ART) among women engaged in commercial sex work (WESW) in Uganda. We used baseline data from a longitudinal study, which recruited 542 WESW in Southern Uganda. We used nested regression models to determine the individual and family, and economic level correlates of self-reported adherence. Study findings show that older age (OR = 1.07, 95% CI = 1.013, 1.139), secondary education (OR = 2.01, 95% CI = 1.306, 3.084), large household size (OR = 1.08, 95% CI = 1.020, 1.136), high family cohesion (OR = 1.06, 95% CI = 1.052, 1.065), and high financial self-efficacy (OR = 1.07, 95% CI = 1.006, 1.130) were associated with good self-reported adherence to ART. Married women (OR=-0.39, 95% CI = 0.197, 0.774), depression (OR = 0.85, 95% CI = 0.744, 0.969), alcohol use (OR = 0.72, 95% CI = 0.548, 0.954), ever been arrested (OR = 0.58, 95% CI = 0.341, 0.997), and high household assets ownership (OR = 0.48, 95% CI = 0.313, 0.724) were associated with poor self-reported adherence to ART. Findings suggest a need to adopt a multi-level approach to address gaps in ART adherence among WESW.

Impact of the COVID-19 Health Crisis on Trans Women and Cis Men Sex Workers in Spain

The objective of the study was to describe the impact of the COVID-19 pandemic on sex workers in accessing health and social services. A qualitative study was conducted using semi-structured interviews with 29 participants in Barcelona, Spain. Data were analyzed using thematic analysis. Four themes were identified: (1) impact of COVID-19 on physical/mental health, (2) barriers and facilitators to health/social service access, (3) health decision-making, and (4) suggestions for future pandemic situations. Barriers to accessing health services were structural. Non-governmental organization support was the main facilitating factor. A person-centered, intersectional approach is suggested for future practice, considering co-occurring syndemic factors.

Mental health and HIV risk differs by co-occurring structural vulnerabilities among women who sell sex

Female sex workers (FSW) experience many structural vulnerabilities (SV; e.g., violence, economic insecurity) which contribute to increased risk of HIV and mental distress. However, little research has examined how SV co-occur to shape HIV risk, and none have studied mental distress. Among FSW (n = 385) in Baltimore, Maryland, latent class analysis of five binary indicators (housing insecurity; financial dependence on others; client-perpetrated physical or sexual violence; food insecurity) determined classes of SV and differential HIV risk behavior and mental health outcomes. A 3-class model fit the data best: minimal SV (i.e., low probabilities of all indicators); material needs (i.e., housing, food insecurity); and high SV (i.e., high probability of all indicators). Compared to minimal SV, high SV and material needs had significantly greater adjusted probability of drug injection and poorer adjusted depression, post-traumatic stress disorder, and mental distress scores. The high SV class had significantly higher probability of reporting condomless sex with clients compared to material needs and minimal SV. Results show the deleterious effect of co-occurring SV on HIV risk behaviors among FSW with particular emphasis on co-occurring food and housing insecurities. This is the first study of co-occurring SV on mental health outcomes in this key population.

Assessing risk factors and health impacts across different forms of exchange sex among young women in informal settlements in South Africa: A cross-sectional study

For women in South Africa, engaging in exchange sex, including transactional sex (TS), or sex work (SW), is associated with several shared poor health outcomes; yet the practices themselves differ in meaningful ways. SW is a form of commodity exchange, while TS is grounded in gendered relationship expectations of male provision and aspects of emotional intimacy. Additionally, exchange sex types could be imagined on a "continuum of instrumentality" from relationships that do not include material support; to those characterized, but not driven by support; to those primarily motivated by material support. We use cross-sectional data from 644 women ages 18-30 enrolled in a trial addressing intimate partner violence in urban KwaZulu-Natal, South Africa to assess whether these conceptualizations may also map onto different types or levels of risk. Using self-reports, we developed four exchange sex relationship categories corresponding to a continuum of instrumentality: no exchange-based relationship; TS with a main partner only; TS with a casual partner; and SW. Using tests of association and adjusted logistic regression models, we compared socio-economic and behavioural risk factors, and health outcomes across reported forms of exchange sex. We find little difference between women who report no exchange sex and those who report TS only with a main partner. By contrast, as compared to women not in exchange sex, women in casual TS and SW were poorer, and significantly more likely to report problematic alcohol use, past drug use, prior non-partner sexual violence, and PTSD; with aOR higher for women in SW for many outcomes. When comparing casual TS to SW, we find women in SW held more gender equitable attitudes and were more likely to report modern contraceptive use. We discuss the implications for distinguishing between TS and SW, and use of the continuum of instrumentality conceptualization for research and programming.

An Evaluation of Indoor Sex Workers' Sexual Health Access in Metro Vancouver: Applying an Occupational Health & Safety Lens in the Context of Criminalization

The criminalization of sex work has been consistently shown to undermine workers' Occupational Health and Safety (OHS), including sexual health. Drawing on the 'Guide to OHS in the New Zealand Sex Industry' (the Guide), we assessed barriers to sexual health best practices among indoor sex workers in Metro Vancouver, Canada, in the context of ongoing criminalization. Part of a longstanding community-based study, this analysis drew on 47 qualitative interviews (2017-2018) with indoor sex workers and third parties. Participants' narratives were analyzed drawing on a social determinants of health framework and on the Guide with specific focus on sexual health. Our findings suggest that sex workers and third parties utilize many sexual health strategies, including use of Personal Protective Equipment (PPE) and peer-driven sexual health education. However, participant narratives demonstrate how structural factors such as criminalization, immigration, and stigma limit the accessibility of additional OHS best practices outlined in the Guide and beyond, including access to non-stigmatizing sexual health assessments, and distribution of diverse PPE by third parties. Our current study supports the need for full decriminalization of sex work, including im/migrant sex work, to allow for the uptake of OHS guidelines that support the wellbeing and autonomy of all sex workers.

Association between interrupted access to sex work community services during the COVID-19 pandemic and changes in sex workers' occupational conditions: findings from a community-based cohort study in Vancouver, Canada

OBJECTIVES

Globally, criminalisation has shaped sex workers' structural exclusion from occupational protections, and this exclusion has been exacerbated during the COVID-19 pandemic. While community organisations aim to bridge this gap through providing health and safety resources for sex workers, many were forced to scale back services when Canadian provinces declared a state of emergency at the pandemic onset. As little empirical research has examined the impacts of sex work community services interruptions amid COVID-19, our objectives were to (1) examine the correlates of interrupted access to community services and (2) model the independent association between interrupted access to community services and changes in working conditions (ie, self-reported increases in workplace violence or fear of violence), among sex workers during the COVID-19 pandemic.

DESIGN, SETTING AND PARTICIPANTS

As part of an ongoing community-based cohort of sex workers in Vancouver, Canada (An Evaluation of Sex Workers Health Access, 2010-present), 183 participants completed COVID-19 questionnaires between April 2020 and April 2021.

ANALYSIS

Cross-sectional analysis used bivariate and multivariable logistic regression with explanatory and confounder modelling approaches.

RESULTS

18.6% of participants (n=34) reported interrupted access to community services (closure/reduction in drop-in hours, reduced access to spaces offering sex worker supports and/or reduced access/contact with outreach services). In multivariable analysis, sex workers who had difficulty maintaining social supports during COVID-19 (adjusted OR, AOR 2.29, 95% CI 0.95 to 5.56) and who experienced recent non-fatal overdose (AOR 2.71, 95% CI 0.82 to 8.98) faced marginally increased odds of service interruptions. In multivariable confounder analysis, interrupted access to community services during COVID-19 was independently associated with changes in working conditions (ie, self-reported increases in workplace violence or fear of violence; AOR 4.00, 95% CI 1.01 to 15.90).

CONCLUSIONS

Findings highlight concerning implications of community service interruptions for sex workers' labour conditions. Sustainable funding to community organisations is urgently needed to uphold sex workers' occupational safety amid COVID-19 and beyond.

Exploring relationships between HIV programme outcomes and the societal enabling environment: A structural equation modeling statistical analysis in 138 low- and middle-income countries

Countries worldwide have attempted to reduce the incidence of HIV and AIDS associated deaths with varying success, despite significant progress in antiretroviral treatment (ART) and condom use. A chief obstacles is that key populations affected face high levels of stigma, discrimination and exclusion, limiting the successful response to HIV. However, a gap exists in studies demonstrating the moderation effects of societal enablers on overall programme effectiveness and HIV outcomes using quantitative methods.Structural Equation Modeling was used for 138 countries covering a 12-year period to examine how the unfavorable societal enabling environment, including stigma and discrimination, unfavorable legal environment and lack of access to societal justice, gender inequality and other unfavorable development situations affect the effectiveness of HIV programmes and HIV outcomes, while controlling for potentially confounding variables. The results only showed statistical significance when all four societal enablers were modeled as a composite. The findings show the direct and indirect standardized effects of unfavorable societal enabling environments to AIDS-related mortality among PLHIV are statistically significant and positive (0.26 and 0.08, respectively). We hypothesize that this may be because an unfavorable societal enabling environment can negatively affect adherence to ART, quality of healthcare and health seeking behavior. Higher ranked societal environments increase the effect of ART coverage on AIDS related mortality by about 50% in absolute value, that is -0.61 as against -0.39 for lower ranked societal environments. However, mixed results were obtained on the impact of societal enablers on changes in HIV incidence through condom use. Results indicate that countries with better societal enabling environments had fewer estimated new HIV infections and fewer AIDS-related deaths. The failure to include societal enabling environments in HIV response undermines efforts to achieve the 2025 HIV targets, and the related 2030 Sustainable Development indicator to end AIDS, even if sufficient resources are mobilized.

Pre-exposure prophylaxis use among female sex workers in Gulu city, Uganda: a community-based cross-sectional study

Background

Pre-exposure prophylaxis (PrEP) is an important intervention for reducing the risk of HIV transmission among high-risk populations such as female sex workers in Africa, where HIV prevalence remains high. We aimed to assess the use of PrEP among female sex workers in Gulu, Uganda.

Methods

In this community-based cross-sectional study, we included HIV-negative female sex workers purposely selected from hotspots within Gulu city, Uganda between February and March 2023. A semi-structured questionnaire was administered to collect data on sociodemographic characteristics, reproductive data, sexual practices, and self-reported PrEP use in the past 3 months. Symptoms of depression were screened using Patient Health Questionnaire-2 tool. Predictors of PrEP use was determined using modified Poisson regression analysis model. p < 0.05 was considered statistically significant.

Results

We enrolled 273 female sex workers with a median age of 27 (interquartile range: 24-32) years. Overall, 181 (66.3%) participants used PrEP. PrEP use was associated with; regular source of income beside sex work [adjusted prevalence ratio (aPR): 3.7, 95% confidence interval (CI): 2.11-6.35, p < 0.001], being in a polygamous marriage (aPR: 6.9, 95% CI: 1.32-35.77, p = 0.022), practicing sex work in both rural and urban areas (aPR: 2.5, 95% CI: 1.49-4.35, p < 0.001), having symptoms of depression (aPR: 3.3, 95% CI: 1.43-7.74, p = 0.005), and use of postexposure prophylaxis (PEP) in the past 12 months (aPR: 0.31, 95% CI: 0.17-0.59, p < 0.001).

Conclusion

Almost two in three of the female sex workers in Gulu city were currently using PrEP. Previous use of PEP was associated with lower use of PrEP. These findings suggest the need for targeted interventions to increase PrEP uptake and decrease HIV acquisition in this high-risk population among female sex workers, especially those with low income and limited access to healthcare.

Factors Associated with Exchange Sex Among Cisgender Persons Who Inject Drugs: Women and MSM-23 U.S. Cities, 2018

Persons who inject drugs (PWID) and exchange sex face disproportionate HIV rates. We assessed prevalence of exchange sex (receiving money/drugs for sex from ≥ 1 male partner(s) during the past year) among cisgender PWID, separately for women and men with a history of sex with men (MSM). We examined factors associated with exchange sex, including sociodemographic characteristics, sexual and drug use behaviors, and healthcare access/utilization. Over one-third of the 4657 participants reported exchange sex (women: 36.2%; MSM: 34.8%). Women who exchanged sex (WES) were significantly more likely to test HIV-positive than other women. Men who exchanged sex with men (MESM) showed a similar trend. WES and MESM shared many characteristics, including being uninsured, experiencing recent homelessness, condomless sex, polydrug use, and receptive/distributive needle sharing. These findings highlight a need to strengthen prevention interventions and address structural determinants of HIV for WES and MESM, particularly PWID who exchange sex.

Awareness, Willingness and Use of HIV Pre-Exposure Prophylaxis Among Female Sex Workers Living in Dar-es-Salaam, Tanzania

Tanzania is in the final stages to roll out pre-exposure prophylaxis (PrEP) to Female Sex Workers (FSWs) so as to reduce new infections. PrEP demonstration projects support programming through gaining first experiences.We analyzed data from a cohort of 700 HIV negative FSWs in Dar-es-Salaam to determine proportions of FSWs who were aware, willing and used PrEP. We compared proportions at cohort enrolment and after 12 months. Logistic regression was used to determine factors associated with PrEP use. PrEP awareness increased from 67% to 97% after 12 months. Willingness was high at both time points (98% versus 96%). Only 8% (57/700) had used PrEP. Being married/cohabiting or separated/divorced/widowed and having sex with a HIV infected partner were independently associated with PrEP use. The PrEP program should focus on scaling up access as willingness to use PrEP is high.

High HIV and syphilis prevalence among female sex workers and sexually exploited adolescents in Nimule town at the border of South Sudan and Uganda

HIV prevalence among the general population in South Sudan, the world's newest country, is estimated at 2.9% and in Nimule, a town at the border with Uganda, it is estimated at 7.5%. However, there is limited data describing the HIV epidemic among female sex workers and sexually exploited adolescents (FSW/SEA) in the country. This study was conducted using a respondent-driven sampling (RDS) among FSW/SEA aged ≥15 years in January-February 2017 who sold or exchanged sex in the last six months in Nimule. Consenting participants were administered a questionnaire and tested for HIV according to the national algorithm. Syphilis testing was conducted using SD BIOLINE Syphilis 3.0 and Rapid Plasma Reagin for confirmation. Data were analyzed in SAS and RDS-Analyst and weighted results are presented. The 409 FSW/SEA participants with a median age of 28 years (IQR 23-35) and a median age of 23 years (IQR 18-28) when they entered the world of sex work, were enrolled in the Eagle survey. Nearly all (99.2%) FSW/SEA lacked comprehensive knowledge of HIV though almost half (48.5%) talked to a peer educator or outreach worker about HIV in the last 30 days. More than half (55.3%) were previously tested for HIV. Only 46.4% used a condom during their last vaginal or anal sexual act with a client. One in five (19.8%) FSW/SEA experienced a condom breaking during vaginal or anal sex in the last six months HIV prevalence was 24.0% (95% CI: 19.4-28.5) and 9.2% (95% CI: 6.5-11.9) had active syphilis. The multivariable analysis revealed the association between HIV and active syphilis (aOR: 6.99, 95% CI: 2.23-21.89). HIV and syphilis prevalence were higher among FSW/SEA in Nimule than the general population in the country and Nimule. Specifically, the HIV prevalence was eight times higher than the general population. Our findings underscore the importance of providing HIV and syphilis testing for FSW/SEA in conjunction with comprehensive combination prevention, including comprehensive HIV information, promotion of condom use, and availing treatment services for both HIV and syphilis.

Sex Work Venue Disorder and HIV/STI Risk Among Female Sex Workers in Two México-US Border Cities: A Latent Class Analysis

Research increasingly recognizes the importance of social and built environments in shaping health, including risks for and outcomes related to HIV and sexually transmitted infections (STI), but research on sex work venues is limited. We use latent class analysis to identify patterns of sex work venue characteristics and factors associated with class membership in two México-US border cities. Among 603 female sex workers (FSW), three classes of sex work venues were identified: low, medium, and high disorder venues, characterized by level of violence, policing and drug activity. In multivariable analysis, risk exposures and outcomes varied by class, suggesting the need for place-based interventions that are tailored to specific venue profiles and that promote FSW health and safety in the workplace.

Validation of a Brief Internalized Sex-work Stigma Scale among Female Sex Workers in Kenya

Female sex workers (FSW) often face severe stigma and discrimination and are extremely vulnerable to HIV and other sexually transmitted infections. In the fields of HIV and mental health, internalized stigma is associated with poor health care engagement. Due to the lack of valid, standardized measures for internalized sex work-related stigma, its dimensions and role are not well-understood. This study aimed to validate the six-item Internalized AIDS-Related Stigma Scale adapted to capture internalized sex work-related stigma by examining the scale's psychometric properties and performance among a cross-sectional, snowball sample of FSW (N = 497) in Kenya. While the original pre-hypothesized six-item model yielded acceptable CFI and SRMR values (CFI = 0.978 and SRMR = 0.038), the RMSEA was higher than desirable (RMSEA = 0.145). Our final four-item model demonstrated improved goodness of fit indices (RMSEA = 0.053; CFI = 0.999; and SRMR = 0.005). Both the pre-hypothesized six-item and reduced final four-item model demonstrated good internal consistency (Cronbach's alphas of 0.8162 and 0.8754, respectively). Higher levels of internalized stigma were associated with depression, riskier sexual behavior, and reduced condom use. This very brief measure will allow for reliable assessment of internalized stigma among FSW. Further investigation of internalized stigma among male sex workers, particularly the intersection of sex work-related and same-sex behavior-related stigmas, is needed.

Harmful Alcohol Use and Associated Socio-Structural Factors among Female Sex Workers Initiating HIV Pre-Exposure Prophylaxis in Dar es Salaam, Tanzania

Harmful alcohol use is an important risk factor for premature mortality and morbidity and associated with increased HIV risk and lower uptake of and adherence to HIV interventions. This study aimed to assess the extent of harmful alcohol use and associated socio-structural vulnerability factors among female sex workers in Dar es Salaam, Tanzania, a key population in the HIV epidemic. Data from a study of female sex workers initiating pre-exposure prophylaxis (PrEP) recruited through respondent driven sampling were used. We assessed harmful alcohol use with the Alcohol Use Disorders Identification Test (AUDIT) defined as having an AUDIT score ≥ 16. Associations between harmful alcohol use and socio-structural factors were assessed using logistic regression with marginal standardization. Of the 470 women recruited, more than one third (37.3%) had a drinking pattern suggestive of harmful alcohol use. Such use was independently associated with sex work-related mobility (aPR: 1.36, 95% CI: 1.11-1.61), arrest/incarceration (aPR: 1.55, 95% CI: 1.27-1.84) and gender-based violence (aPR: 1.31, 95% CI: 1.06-1.56). The high prevalence of harmful alcohol use and the interconnectedness with socio-structural factors indicate a need for a holistic programmatic approach to health for female sex workers. Programming should not solely direct attention to individual behavior but also include strategies aiming to address socio-structural vulnerabilities.

Exploring the Influence of Social Capital on HIV Prevention with Migrants from the Democratic Republic of Congo (DRC) Living in Durban, South Africa

Background: Research shows a growing attentiveness to the role of social and environmental influences on HIV risk behaviours. Moreover, the understanding of HIV risk behaviours has moved from an earlier consideration of individual risk, to ecological models, with the understanding that behaviours are rooted in the economic, environmental and social structure. Aim: To explore how social capital, specifically on a social bonding level, operates as a risk or protective factor for the spread of HIV among French-speaking migrants from the Democratic Republic of Congo (DRC), living in Durban, South Africa. Methods: A qualitative approach using a case study design was used to conduct the study. Data were collected through focus group discussions and individual in-depth interviews from a purposive sample of French-speaking migrants from DRC, living in Durban, South Africa. Ethical approval to conduct the study was obtained from the University of KwaZulu-Natal's Human and Social Science Research Ethics' Committee. Data were analysed thematically using Creswell's steps of data analysis. Results: This study found that social capital can act as both a protective factor in certain circumstances, and a risk factor in others. Trust, norms, reciprocity and social networks are complex elements in the refugee community and are influenced by a myriad of factors including the past and present stressors that are prevalent within this community. Conclusions: The findings confirm the complexity of issues related to HIV prevention which necessitate policy and practice interventions to mitigate consequences that may result from the higher risks of HIV transmission in this community.

Sexualized Substance Use among Female Sex Workers in Iran: Findings from a Nationwide Survey

Background: Female sex workers (FSWs) are at higher risk of HIV due to high-risk sexual and drug use related behaviors. This study characterized sexualized substance use among FSWs in Iran. Methods: In 2015, 1,337 FSWs were recruited from centers for vulnerable women and through outreach efforts in 13 major cities in Iran. Data were collected via face-to-face interviews from consenting FSWs on a range of socio-demographic and behavioral characteristics. The primary outcome of interest was sexualized substance use, defined as reporting alcohol or drug use before or during sex in the past month. Bivariable and multivariable modified Poisson regression models were used to assess the correlates of sexualized substance use. Adjusted prevalence ratio (aPR) and 95% confidence interval (CI) were reported. Results: The prevalence of sexualized substance use was 31.3% (95% CI: 28.7, 34.0). Inconsistent condom use during sex with clients in the past month (aPR = 1.31; 95% CI: 1.01, 1.71), regular (i.e., at least weekly in the past month) alcohol use (aPR = 2.87; 95% CI: 2.17, 3.80), regular opioid use (aPR = 2.09; 95% CI: 1.45, 3.02), regular stimulant use (aPR = 2.68; 95% CI: 2.12, 3.39), and self-reported HIV negative status (aPR= 1.88; 95% CI: 1.14, 3.10) were significantly and positively associated with sexualized substance use. Conclusions: Sexualized substance use was associated with riskier sexual behavior and self-reported HIV sero-negativity. Harm reduction messaging to FSWs needs to go beyond focusing on sexual health promotion and further highlight the risks associated with sexualized substance use.

Barriers and facilitators for access and utilization of reproductive and sexual health services among Female Sex Workers in urban and rural Maharashtra, India

Background

The public health interventions among Female Sex Workers (FSWs) have mainly addressed HIV/ STI prevention. The focus of the HIV prevention program on FSWs' Reproductive and Sexual Health (RSH) has been limited, thus, rendering them at a higher risk of unintended pregnancies, delayed pregnancy detection, and utilizing unsafe abortion methods.

Methods

A multistakeholder analysis was performed to study access and use of RSH services among FSWs in urban and rural India. Between January 2016 and June 2019, a qualitative grounded theory approach was used to explore the FSWs' perspectives and experiences about services pertaining to HIV prevention, Antenatal Care (ANC), child delivery, abortion, and pregnancy prevention. Using purposive and convenience sampling, 29 In-Depth Interviews (IDIs), 2 Focus Group Discussions (FGDs) and 22 Key Informant Interviews (KIIs) were conducted with consenting FSWs and indirect stakeholders, respectively. Verbatim translated data was entered in NVivo12 Software and analyzed inductively.

Results

The following themes emerged: (1) Condomless sex, unintended pregnancy, vertical transmission, (2) Signs/ indication used for pregnancy detection causing delay (3) Pregnancy prevention methods used, (4) Pregnancy prevention or AIDS prevention, (5) Legal formalities as a barrier to access RSH, (6) Differential facility preference.

Conclusion

Pregnancy prevention is a greater motivation for condom use than HIV prevention among FSWs. Therefore, there is an emerging need to reallocate public health resources and redesign policies to meet the RSH needs of FSWs, especially for the prevention of unintended pregnancies. FSW-focused Information Education Communication (IEC) strategies for RSH service utilization are essential to reduce the burden of unintended pregnancies. The National HIV Targeted Intervention (TI) program needs to include pregnancy testing services and information to non-barrier contraceptive methods. An ambient policy environment calls for examining the need for male involvement in pregnancy, family planning and abortion decisions.

"What will we do if we get infected?": An interview-based study of the COVID-19 pandemic and its effects on the health and safety of sex workers in the United States

Emerging evidence suggests that sex workers face unique and profound risks arising from the COVID-19 pandemic. To illuminate the pandemic's effects on sex worker health and safety and identify intervention opportunities, from May-August 2020 in-depth interviews were conducted with a purposive sample of 15 sex workers, four service providers and two individuals who were both. Sampled sex workers included eight people of color, eight cisgender women, five cisgender men, three non-binary people, and one transgender woman. Using Conservation of Resources Theory to define impacts on sex worker resources and resulting health and safety implications, a deductive thematic analysis was conducted. Seven resources were threatened due to the pandemic: work opportunity, sex work venues, social support, health services, money, food, and housing. The loss of these resources was exacerbated by stigma - notably sex work criminalization - and significantly undermined health and safety by increasing food and housing instability, increasing risks of violence, and diminishing safer sex negotiation. Six resources were activated in response: social support, digital skills, health knowledge, non-sex work employment, money, and resilience. While social support had numerous benefits, investing digital skills and non-sex work employment were generally of limited impact. The pandemic's negative health and safety effects were most profound at the intersections of race, gender, class, and migration status. These findings suggest sex workers need urgent and ongoing support, with investments in social support and sex work decriminalization likely to have the greatest effects on health and safety relative to and beyond the COVID-19 pandemic.

The Effect of Systemic Racism and Homophobia on Police Enforcement and Sexual and Emotional Violence among Sex Workers in East London: Findings from a Cohort Study

There is extensive qualitative evidence of violence and enforcement impacting sex workers who are ethnically or racially minoritized, and gender or sexual minority sex workers, but there is little quantitative evidence. Baseline and follow-up data were collected among 288 sex workers of diverse genders (cis/transgender women and men and non-binary people) in London (2018-2019). Interviewer-administered and self-completed questionnaires included reports of rape, emotional violence, and (un)lawful police encounters. We used generalized estimating equation models (Stata vs 16.1) to measure associations between (i) ethnic/racial identity (Black, Asian, mixed or multiple vs White) and recent (6 months) or past police enforcement and (ii) ethnic/racial and sexual identity (lesbian, gay or bisexual (LGB) vs. heterosexual) with recent rape and emotional violence (there was insufficient data to examine  the association with transgender/non-binary identities). Ethnically/racially minoritized sex workers (26.4%) reported more police encounters partly due to increased representation in street settings (51.4% vs 30.7% off-street, p = 0.002). After accounting for street setting, ethnically/racially minoritized sex workers had higher odds of recent arrest (adjusted odds ratio 2.8, 95% CI 1.3-5.8), past imprisonment (aOR 2.3, 95% CI 1.1-5.0), police extortion (aOR 3.3, 95% CI 1.4-7.8), and rape (aOR 3.6, 95% CI 1.1-11.5). LGB-identifying sex workers (55.4%) were more vulnerable to rape (aOR 2.4, 95% CI 1.1-5.2) and emotional violence. Sex workers identifying as ethnically/racially minoritized (aOR 2.1, 95% CI 1.0-4.5), LGB (aOR 2.0, 95% CI 1.0-4.0), or who use drugs (aOR 2.0, 95% CI 1.1-3.8) were more likely to have experienced emotional violence than white-identifying, heterosexual or those who did not use drugs. Experience of any recent police enforcement was associated with increased odds of rape (aOR 3.6, 95% CI 1.3-8.4) and emotional violence (aOR 4.9, 95% CI 1.8-13.0). Findings show how police enforcement disproportionately targets ethnically/racially minoritized sex workers and contributes to increased risk of rape and emotional violence, which is elevated among sexual and ethnically/racially minoritized workers.

Association Between Multiple Experiences of Violence and Drug Overdose Among Black Women in Community Supervision Programs in New York City

Research has documented associations between all types of violence and substance misuse among Black women. However, research has yet to examine how different experiences of violence may be contributing to the surging epidemic of drug overdose among Black women. This study was conducted between 2015 and 2018 among 296 Black women who were mandated to community supervision programs (CSPs) in New York City (NYC). We used generalized linear modeling (GLM) to estimate associations of the adjusted relative risk (aRR) of experiencing a non-fatal overdose based on exposure to each type of violence after controlling for potentially confounding variables. Lifetime prevalence of a non-fatal drug overdose was 13.9% (n = 41). Lifetime severe physical/sexual violence by a male intimate partner (prevalence rate = 61.8%, n = 181) was associated with an overdose (aRR = 3.41, 95%CI = 1.19, 9.73). Severe violence by a female partner (prevalence rate = 7.4%, n = 22) was also associated with an overdose (aRR = 2.61, 95%CI = 1.46, 4.65). Lifetime sexual violence by a non-intimate partner (prevalence rate: 29.1%, n = 86) was associated with an overdose (aRR = 2.23, 95%CI = 1.32, 3.77). Sexual abuse by police/CSP staff (prevalence rate: 14.9%, n = 44) was associated with an overdose (aRR = 2.29, 95%CI = 1.27, 4.12). For each increase in the number of types of violence experienced, there was a 27% increase in the risk for an overdose (aRR = 1.27, 95%CI = 1.14, 1.42). This study found high rates of multiple types of violence that are associated with drug overdose among this sample of Black women in CSPs. These findings highlight the urgent public health need to address violence associated with overdose in this population.

Violence against sex workers: Correlates and Changes under 'End-Demand' legislation in Canada: A five city study

Canada is among several countries to have implemented 'end-demand' criminalization frameworks for sex work. Drawing on interviews with sex workers (n = 200) in five cities, we employed multivariate logistic regression to identify associations with workplace violence. We also analysed descriptive data on trafficking and on workplace violence under end-demand legislation. In the past 12 months, being unable to call 911 in a safety emergency at work for fear of police detection (Adjusted Odd Ratio AOR: 4.307, 95% Confidence Interval CI: 1.697 -10.927), being unable to screen clients due to fear of police detection (AOR: 2.175, 95% CI: 1.074 -4.405), having experienced anti-sex work housing policy/eviction (AOR: 2.031, 95% CI: 0.897-4.598), and being Indigenous (Adjusted Odd Ratio (AOR): 2.167, 95% Confidence Interval (CI): 1.060-4.428) were all independently associated with workplace violence in the past 12 months. Of those who worked prior to the law change (n = 167), a majority of respondents (80.24% (134)) reported that violence in the workplace had increased or stayed the same compared to the previous criminalization model and 87.43% (n = 146) reported it was harder or the same to get help in an emergency.

A retreat from human rights? A reflection on sex work's place in contemporary HIV prevention

In 2012, the World Health Organization guidelines for HIV prevention recommended the decriminalisation of sex work as their number one good practice. Although human rights language played a key role in the international scientific and activist endorsement of the WHO policies, since then there have been few initiatives in terms of advancing the kinds of structural and political changes endorsed. In this Commentary, we reflect on sex work's place in the broader field of the biomedicalization of responses to HIV. The analysis is based on literature reviews and our research trajectories, including preliminary results from a qualitative study on the implementation of PrEP in Rio de Janeiro, Brazil. We argue that sex workers occupy an ambiguous and less visible role in current AIDS policies, and that such policies are increasingly characterised by their prioritisation of biomedical approaches over structural factors. These shifts should be understood as part of a broader, global hegemony of clinical responses to HIV prevention and the continuation of a neoliberal discourse around human rights, without adequate investment in the material conditions necessary to guarantee these rights.

Learning from women who trade sex in Kenya about the antiblackness of Global Health

Sex work and violence have become co-constituted, routinized, and even sanitized in Global Health journals dispassionately advocating for intervention. This paper situates ethnographically shared experiences of Kenyan sex working women within the global condition of antiblackness. By grounding our conceptual analytic in Black Feminist scholarship, we illustrate how antiblackness subtends the conditions of possibility for women's entry into sex work, their subsequent experiences with interpersonal and institutional forms of predatory violence, and lack of recourse for their material needs and suffering. This analysis requires a meditation on the relationships between the types of violence conditioning Kenyan women's lives and the limitations of Global Health's conceptual logics and disciplinary practice. Our discussion reflects on the ways Global Health practice can neglect conceptual foundations in antiblackness, thus complicit in upholding violence against the very groups it purports to assist. In charging Global Health "as usual" as methodologically violent and sustaining global antiblackness, we call for disciplinary transformations beginning from a shared consciousness regarding the ways global antiblackness structures health inequities. Beyond critique, our meditation is an invitation for all committed to dignified Global Health to contribute creative, non-hierarchically collaborative work engaged with those in material, structural, and immaterial need.

Characterization of Patients Seeking Care at a Sexual Health Clinic Who Report Engaging in Exchange Sex

BACKGROUND

People who exchange sex (PWES) for money or drugs are at increased risk for poor health outcomes and may be reluctant to engage in health services.

METHODS

We conducted a cross-sectional analysis of patients seen for new problem visits at the Public Health-Seattle and King County Sexual Health Clinic between October 2010 and March 2020 who reported exchanging sex for drugs or money in a computer assisted self-interview. We analyzed demographics; sexually transmitted infections (STIs), human immunodeficiency virus (HIV), and hepatitis C virus (HCV) history; and HIV preexposure prophylaxis (PrEP) use, stratified by gender. We compared characteristics of people who ever versus never exchanged sex using χ 2 tests and analyzed the visit reason and outcomes among PWES.

RESULTS

Among 30,327 patients, 1611 (5%) reported ever exchanging sex: 981 (61%) cisgender men, 545 (34%) cisgender women, and 85 (5%) transgender and gender diverse persons. Compared with people who never exchanged sex, PWES were more likely to report homelessness (29% vs 7%, P < 0.001), injection drug use (39% vs 4%, P < 0.001), prior STIs (36% vs 19%, P < 0.001), prior HIV diagnosis (13% vs 5%, P < 0.001), and prior HCV diagnosis (13% vs 2%, P < 0.001). People who exchange sex came to the clinic seeking STI tests (60%), HIV tests (45%), and care for STI symptoms (38%). Overall, 320 (20%) PWES were diagnosed with STIs, 15 (1%) were newly diagnosed with HIV, and 12 (1%) initiated PrEP at the visit.

CONCLUSION

People who exchange sex have complex barriers to care, and sexual health clinic visits present an opportunity to improve health services for this population.

HIV awareness, pre-exposure prophylaxis perceptions and experiences among people who exchange sex: qualitative and community based participatory study

Background

People who exchange sex for money, favors, goods or services, combat higher risk of acquiring sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV). Understanding barriers to STD and HIV related healthcare from the perspective of this stigmatized and marginalized community may improve access to sexual health services including pre-exposure prophylaxis (PrEP). 

Methods

We used community-partnered participatory and qualitative methods to conduct anonymous one-on-one interviews with people who exchange sex to understand their perspectives and experiences related to pre-exposure prophylaxis (PrEP) to prevent HIV acquisition. We conducted twenty-two interviews and coded them to perform thematic analysis. 

Results

We identified five themes: (1) Appreciation of HIV risk and prevention strategies grew from information accumulated over time. (2) PrEP information came from a variety of sources with mixed messages and uncertain credibility. (3) Decision-making about use of PrEP was relative to other behavioral decisions regarding exchange sex. (4) The multi-step process of obtaining PrEP presented multiple potential barriers. (5) Healthcare providers were seen as powerful facilitators to PrEP utilization.

Conclusions

Our findings suggest that PrEP education and care needs to be made more relevant and accessible to individuals who exchange sex.

The association of gender with receptive and distributive needle sharing among individuals who inject drugs

Background

Injection drug use and needle sharing remains a public health concern due to the associated risk of HIV, HCV and skin and soft tissue infections. Studies have shown gendered differences in the risk environment of injection drug use, but data are currently limited to smaller urban cohorts.

Methods

To assess the relationship between gender and needle sharing, we analyzed publicly available data from the 2010–2019 National Survey on Drug Use and Health (NSDUH) datasets. Chi-square tests were conducted for descriptive analyses and multivariable logistic regression models were built adjusting for survey year, age, HIV status, and needle source.

Results

Among the entire sample, 19.8% reported receptive needle sharing, 18.8% reported distributive sharing of their last needle, and 37.0% reported reuse of their own needle during last injection. In comparison with men, women had 34% increased odds (OR 1.34, 95% CI 1.11–1.55) of receptive needle sharing and 67% increased odds (OR 1.67, 95% CI 1.41–1.98) of distributive needle sharing. Reuse of one's own needle did not differ by gender.

Conclusions

In this nationally representative sample, we found that women are more likely in comparison with men to share needles both through receptive and distributive means. Expansion of interventions, including syringe service programs, to increase access to sterile injection equipment is of great importance.

Prevalence and predictors of HIV and sexually transmitted infections among vulnerable women engaged in sex work: Findings from the Kyaterekera Project in Southern Uganda

INTRODUCTION

Women engaged in sex work (WESW) have an elevated risk of the human immunodeficiency virus (HIV) and sexually transmitted infections (STI). Estimates are three times higher than the general population. Understanding the predictors of HIV and STI among WESW is crucial in developing more focused HIV and STI prevention interventions among this population. The study examined the prevalence and predictors of HIV and STI among WESW in the Southern part of Uganda.

METHODOLOGY

Baseline data from the Kyaterekera study involving 542 WESW (ages 18-55) recruited from 19 HIV hotspots in the greater Masaka region in Uganda was utilized. HIV and STI prevalence was estimated using blood and vaginal fluid samples bioassay. Hierarchical regression models were used to determine the predictors of HIV and STI among WESW.

RESULTS

Of the total sample, 41% (n = 220) were found to be HIV positive; and 10.5% (n = 57) tested positive for at least one of the three STI (Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis) regardless of their HIV status. Older age (b = 0.09, 95%CI = 0.06, 0.13, p≤0.001), lower levels of education (b = -0.79, 95%CI = -1.46, -0.11, p≤0.05), fewer numbers of children in the household (b = -0.18, 95%CI = -0.36, -0.01), p≤0.05), location (i.e., fishing village (b = 0.51, 95%CI = 0.16, 0.85, p≤0.01) or small town (b = -0.60, 95%CI = -0.92, -0.28, p≤0.001)), drug use (b = 0.58, 95%CI = 0.076, 1.08, p≤0.05) and financial self-efficacy (b = 0.05, 95%CI = -0.10, 0.00, p≤0.05), were associated with the risk of HIV infections among WESW. Domestic violence attitudes (b = -0.24, 95%CI = -0.42, -0.07, p≤0.01) and financial distress (b = -0.07, 95%CI = -0.14, -0.004, p≤0.05) were associated with the risk of STI infection among WESW.

CONCLUSION

Study findings show a high prevalence of HIV among WESW compared to the general women population. Individual and family level, behavioural and economic factors were associated with increased HIV and STI infection among WESW. Therefore, there is a need for WESW focused HIV and STI risk reduction and economic empowerment interventions to reduce these burdens.

Opportunities and considerations for the design of decentralized delivery of antiretroviral therapy for female sex workers living with HIV in South Africa

Background

In South Africa, 60% of female sex workers (FSW) are living with HIV, many of whom experience structural and individual barriers to antiretroviral therapy (ART) initiation and adherence. Community-based decentralized treatment provision (DTP) may mitigate these barriers. To characterize optimal implementation strategies, we explored preferences for DTP among FSW living with HIV in Durban, South Africa.

Methods

Thirty-nine semi-structured in-depth interviews were conducted with FSW living with HIV (n = 24), and key informants (n = 15) including HIV program implementers, security personnel, and brothel managers. Participants were recruited using maximum variation and snowball sampling. Interviews were conducted in English or isiZulu between September–November 2017 and analyzed using grounded theory in Atlas.ti 8.

Results

DTP was described as an intervention that could address barriers to ART adherence and retention, minimizing transport costs, time and wage loss from clinic visits, and act as a safety net to address FSW mobility and clinic access challenges. Respondents highlighted contextual considerations for DTP and suggested that DTP should be venue-based, scheduled during less busy times and days, and integrate comprehensive health services including psychological, reproductive, and non-communicable disease services. ART packaging and storage were important for community-based delivery, and participants suggested DTP should be implemented by sex work sensitized staff with discrete uniform and vehicle branding.

Conclusions

Incorporating FSW preferences may support implementation optimization and requires balancing of tensions between preferences and feasibility. These data suggest the potential utility of DTP for FSW as a strategy to address those most marginalized from current ART programs in South Africa.

Health vulnerabilities in female sex workers in Brazil, 2016

Female sex workers (FSW) suffer stigma and discrimination that negatively impact their physical and mental health and affect access to health care services. This paper aims to describe selected health indicators among FSW in 12 Brazilian cities in 2016. Brazilian cross-sectional Biological Behavioral Surveillance Survey was conducted in 2016 among 4328 FSW recruited by respondent-driven sampling. The sample weighing was inversely proportional to participant's network sizes and the seeds were excluded from the analysis. Health indicators were estimated with 95% confidence interval and included indicators of health status, symptoms of depression, antenatal care, pap smear coverage, signs and symptoms of sexually transmitted infection, contraception and regular condom use, number of births and children alive per women, human immunodeficiency virus and syphilis testing, usual source of care, and perception of discrimination. Most participants self-rated their health as very good/good (65.8%) and 27.7% were positively screened for major depressive disorder episode on Patient Health Questionnaire-2. Antenatal coverage was 85.8% and 62.3% of FSW had access to pap smear exam in the past 3 years. A total of 67.0% of FSW were using some contraceptive method at the time of the study. Male condom was the most common method (37.1%), followed by oral pill (28.9%). A total of 22.5% FSW had never been tested for HIV and the main reasons were "not feeling at risk" (40.4%) and "being afraid or ashamed" (34.0%). The vast majority of FSW used Brazilian National Health System as their usual source of health care (90.2%). Approximately one-fifth of the participants felt discriminated against or were treated worse for being FSW (21.4%) and only 24.3% disclose their sex work status in health services. The vulnerability of FSW is expressed in all health indicators. Indicators of health status, antenatal care, pap smear coverage, and contraception were worse than in the Brazilian population, and point out to the importance of increase FSW's access to health care services. Also, stigma and discrimination emerged as an important barrier to FSW's health care in all dimensions and need to be struggled.

Sex work stigma and the recuperation of moral personhood through gendered labour: sex worker diaries in Ukraine

Based on a diary writing exercise, this paper illuminates the complex ways in which sex workers in Ukraine actively work through and manage stigma in their daily lives. Pushing beyond the notion of stigma as a static and fixed psychosocial designation that can be readily measured, we argue that stigma is actively confronted by sex workers through various forms of gendered emotional and physical labour that enable them to recuperate a sense of moral personhood. This notion of moral personhood is often tied to wider gender-specific values pertaining to caregiving and motherhood.

BARRIERS TO GOVERNMENTAL INCOME SUPPORTS FOR SEX WORKERS DURING COVID-19: RESULTS OF A COMMUNITY-BASED COHORT IN METRO VANCOUVER

The COVID-19 pandemic has brought into stark focus the economic inequities faced by precarious, criminalized and racialized workers. Sex workers have been historically excluded from structural supports due to criminalization and occupational stigma. Given emerging concerns regarding sex workers' inequitable access to COVID-19 income supports in Canada and elsewhere, our objective was to identify prevalence and correlates of accessing emergency income supports among women sex workers in Vancouver, Canada. Data were drawn from a longstanding community-based open cohort (AESHA) of cis and trans women sex workers in Metro Vancouver from April 2020-April 2021 (n = 208). We used logistic regression to model correlates of access to COVID-19 income supports. Among 208 participants, 52.9% were Indigenous, 6.3% Women of Colour (Asian, Southeast Asian, or Black), and 40.9% white. Overall, 48.6% reported accessing income supports during the pandemic. In adjusted multivariable analysis, non-injection drug use was associated with higher odds of accessing COVID-19 income supports (aOR: 2.58, 95% CI: 1.31-5.07), whereas Indigenous women faced reduced odds (aOR 0.55, 95% CI 0.30-1.01). In comparison with other service workers, access to income supports among sex workers was low overall, particularly for Indigenous sex workers, demonstrating the compounding impacts of colonization and disproportionate criminalization of Indigenous sex workers. Results highlight the need for structural supports that are low-barrier and culturally-safe to support sex workers' health, safety and dignity.

HIV prevention for the next decade: Appropriate, person-centred, prioritised, effective, combination prevention

UNAIDS and a broad range of partners have collaborated to establish a new set of HIV prevention targets to be achieved by 2025 as an intermediate step towards the sustainable development target for 2030.The number of new HIV infections in the world continues to decline, in part due to the extraordinary expansion of effective HIV treatment. However, the decline is geographically heterogeneous, with some regions reporting a rise in incidence. The incidence target that was agreed for 2020 has been missed.A range of exciting new HIV prevention technologies have become available or are in the pipeline but will only have an impact if they are accessible and affordable and delivered within systems that take full account of the social and political context in which most infections occur. Most new infections occur in populations that are marginalised or discriminated against due to structural, legal, and cultural barriers.The new targets imply a new approach to HIV prevention that emphasises appropriate, person-centred, prioritised, effective, combination HIV prevention within a framework that reduces existing barriers to services and acknowledges heterogeneity, autonomy, and choice.These targets have consequences for people working in HIV programmes both for delivery and for monitoring and evaluation, for health planners setting local and national priorities, and for funders both domestic and global. Most importantly, they have consequences for people who are at risk of HIV exposure and infection.Achieving these targets will have a huge impact on the future of the HIV epidemic and put us back on track towards ending AIDS as a public health threat by 2030.

Behavioural Risk for HIV, Hepatitis B, and Hepatitis C Infections among a Population of Drug Users and Injectors across Four Regions in Ghana

Background

Blood borne infections such as HIV, Hepatitis B (HBV), and Hepatitis C (HCV) are of great importance to governments and their implementing partners, especially among people who use drugs (PWUD) and people who inject drugs (PWID). Prevalence and determinants of HIV, HBV, and HCV among PWUD and PWID in Ghana are not well established, the significance of this study.

Method

This assessment was a cross-sectional study implemented via the respondent driven sampling approach. A team of community advisory boards that comprised former users, current users, and civil society organizations were constituted to help in the implementation of the study. The study was conducted in four regions in Ghana. The assessment was based on a representation of populations of PWID and PWUD from the four regions. Efforts were made by the team to ensure adequate representation of women where feasible. A quantitative questionnaire was developed and used to obtain information on the respondents' sociodemographics, sexual behavior, substance use, and biological characteristics. The prevalence of HIV, HBV, and HCV among PWID and PWUD was determined using blood samples. First response and oral quick test for confirmation of HIV positivity were carried out, while SD bioline was used to test for the presence of HBV and HBC. Data were analyzed using the Bayesian generalized linear model via the binomial family of distributions under the logit link function with weak Cauchy and Normal distribution as prior.

Results

A total of 323 PWUD and PWID participants were interviewed across four regions of Ghana. The overall median age of the respondents was 36 (28, 43) years. The prevalence of HIV, HBV, and HCV infection in the study was 2.5%, 4.6%, and 5.9%, respectively. The prevalence of HIV, HBV, and HCV among drug users was 2.5% (95% CI: 0.7%–4.2%), 4.1% (95% CI: 1.8%–6.2%), and 6.7% (95% CI: 3.9%–9.4%), respectively. Most drug injectors and users started using and injecting drugs at ages less than 20 years and between 20 and 29 years, respectively. Drug users who identified themselves as part of the general population were 66% less likely to be tested HIV positive (POR = 0.34, CrI: 0.12–0.81) compared to sex workers. Part time employment respondents had fivefold odds (POR = 5.50, CrI: 1.20–16.16) of being HBV positive as against full-time employment.

Conclusion

Most of the injectors and users started drugs at an early age. Drug users and injectors are at higher risk of these infections because of associated risky sexual behaviors and risky injection practices. Harm reduction programs to help addicts who are willing to quit the practice are recommended.

Understanding the longitudinal relationship between substance use and violent victimization among street-based women who exchange sex in Baltimore, Maryland

BACKGROUND

Women who exchange sex (WES) experience extensive interpersonal violence from multiple perpetrators. Violence towards WES contributes to poor mental and behavioral health outcomes, including high rates of drug use. However, it is difficult to disentangle the temporal relationship between drug use and violence among WES.

METHODS

We used data from 251 WES, who completed baseline and 6-month follow up surveys. WES reported baseline sociodemographic characteristics, including homelessness and hunger. Participants reported their drug use by type and violent experiences by perpetrator at each time point. We conducted a path analysis examining the associations between drug use and violent victimization over time.

RESULTS

Participants were on average 37.8 years old, non-Hispanic White (57.4%) and experiencing high levels of structural vulnerability (59.4% homelessness; 58.6% weekly hunger). Drug use and violence were significantly correlated within each time point. Prospectively, baseline violent victimization was significantly associated with drug use (ß (SE) = 0.13 (0.06)) and violence (ß (SE) = 0.47 (0.05)) at follow up. Baseline drug use was associated with drug use at follow up (ß (SE) = 0.45 (0.05)) but was not significantly associated with violence at follow up (ß (SE) = 0.10 (0.06)).

CONCLUSIONS

Violence and drug use are closely linked in this population; and violence appears to facilitate sustained drug use. Interventions to address the dual epidemics of violence and substance use in this population should address underlying trauma as well as socio-structural drivers of violence as well as tailored harm reduction services for this population.

Social and structural determinants of health associated with police violence victimization: A latent class analysis of female sex workers who use drugs in Kazakhstan

INTRODUCTION

Punitive legal environments remain a challenge to HIV prevention efforts in Central Asia, and female sex workers who use drugs are vulnerable to police violence. Little is known about the heterogeneity of police violence against female sex workers who use drugs and factors associated with HIV risk in Central Asia, despite the growing HIV epidemic.

METHODS

We recruited a community-based sample of 255 female sex workers who use drugs in Almaty, Kazakhstan between February 2015 and May 2017. We used latent class analysis to differentiate women into distinct classes of police violence victimization, and multinomial logistic regression to identify individual-level health outcomes, HIV risk behaviors, and social and structural factors within the risk environment associated with class membership.

RESULTS

A three-class model emerged: Low Victimization (51%), Discrimination and Extortion (15%), and Poly-Victimization (34%). Relative to Low Victimization, factors associated with Poly-Victimization included being positive for HIV and/or sexually-transmitted infections (STI) (aOR: 1.78 (95% CI: 1.01, 3.14)), prior tuberculosis diagnosis (2.73 (1.15, 6.50)), injection drug use (IDU) (2.00 (1.12, 3.58)), greater number of unsafe IDU behaviors (1.21 (1.08, 1.35)), homelessness (1.92 (1.06, 3.48)), greater drug use (1.22 (1.07, 1.39)) and sex work stigma (1.23 (1.06, 1.43)), greater number of sex work clients (2.40 (1.33, 4.31)), working for a boss/pimp (2.74 (1.16, 6.50)), client violence (2.99 (1.65, 5.42)), economic incentives for condomless sex (2.77 (1.42, 5.41)), accessing needle/syringe exchange programs (3.47 (1.42, 8.50)), recent arrest (2.99 (1.36, 6.55)) and detention (2.93 (1.62, 5.30)), and negative police perceptions (8.28 (4.20, 16.3)). Compared to Low Violence, Discrimination and Extortion was associated with lower odds of experiencing intimate partner violence (aOR= 0.26 (0.12, 0.59)), but no other significant associations with the risk environment upon adjusting for socio-demographic characteristics.

CONCLUSION

Police violence against female sex workers who use drugs is pervasive in Kazakhstan. Patterns of police violence vary, with greater HIV susceptibility associated with a higher probability of experiencing multiple forms of police violence. Police sensitization workshops that integrate policing and harm reduction, and drug policy reforms that decriminalize drug use may help mitigate the HIV epidemic in Kazakhstan.

HIV prevention programme with young women who sell sex in Mombasa, Kenya: learnings for scale-up

Introduction

In 2018, the National AIDS and sexually transmitted infection (STI) Control Programme developed a national guidelines to facilitate the inclusion of young women who sell sex (YWSS) in the HIV prevention response in Kenya. Following that, a 1‐year pilot intervention, where a package of structural, behavioural and biomedical services was provided to 1376 cisgender YWSS to address their HIV‐related risk and vulnerability, was implemented.

Methods

Through a mixed‐methods, pre/post study design, we assessed the effectiveness of the pilot, and elucidated implementation lessons learnt. The three data sources used included: (1) monthly routine programme monitoring data collected between October 2019 and September 2020 to assess the reach and coverage; (2) two polling booth surveys, conducted before and after implementation, to determine the effectiveness; and (3) focus group discussions and key informant interviews conducted before and after intervention to assess the feasibility of the intervention. Descriptive analysis was performed to produce proportions and comparative statistics.

Results

During the intervention, 1376 YWSS were registered in the programme, 28% were below 19 years of age and 88% of the registered YWSS were active in the last month of intervention. In the survey, respondents reported increases in HIV‐related knowledge (61.7% vs. 90%, p <0.001), ever usage of pre‐exposure prophylaxis (8.5% vs. 32.2%, p < 0.001); current usage of pre‐exposure prophylaxis (5.3% vs. 21.1%, p<0.002); ever testing for HIV (87.2% vs. 95.6%, p <0.04) and any clinic visit (35.1 vs. 61.1, p <0.001). However, increase in harassment by family (11.7% vs. 23.3%, p<0.04) and discrimination at educational institutions (5.3% vs. 14.4%, p<0.04) was also reported. In qualitative assessment, respondents reported early signs of success, and identified missed opportunities and made recommendations for scale‐up.

Conclusions

Our intervention successfully rolled out HIV prevention services for YWSS in Mombasa, Kenya, and demonstrated that programming for YWSS is feasible and can effectively be done through YWSS peer‐led combination prevention approaches. However, while reported uptake of treatment and prevention services increased, there was also an increase in reported harassment and discrimination requiring further attention. Lessons learnt from the pilot intervention can inform replication and scale‐up of such interventions in Kenya.

The Importance of Sexual Orientation in the Association Between Social Cohesion and Client Condom Coercion Among Women Who Exchange Sex in Baltimore, Maryland

Among women who exchange sex (WES), social cohesion is associated with multi-level HIV-risk reduction factors, and client condom coercion (CCC) is associated with increased HIV-risk. Sexual minority WES (SM-WES) face exacerbated HIV-risk, yet relevant research is scant. We examined the role of sexual orientation in the relationship between social cohesion and CCC among cisgender WES (n = 384) in Baltimore, Maryland using stratified logistic regression, controlling for potential confounders. Forty-five percent of WES experienced CCC. SM-WES reported significantly higher social cohesion than heterosexual WES. The relationship between social cohesion and CCC differed by sexual orientation. Among SM-WES, higher social cohesion was independently associated with decreased odds of experiencing CCC, controlling for food insecurity, crack use, police harassment, and method of finding clients. Among heterosexual WES, no significant association was found. Ongoing research and practice with WES should (1) collect sexual orientation data to allow for deeper understanding and tailored interventions, (2) leverage and nurture social cohesion and (3) tailor interventions to populations with attention to sexual orientation.

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.

Cultivating PEARL (Promoting Empowerment and Risk Reduction): Formative Research for a PrEP Intervention Among Female Sex Workers in Baltimore, Maryland

Pre-exposure prophylaxis (PrEP) is a vital component of comprehensive HIV prevention among female sex workers (FSW). There are limited PrEP interventions targeting FSW in the U.S., who have high HIV risk. Formative research was conducted to inform PEARL (Promoting Empowerment And Risk Reduction), a PrEP intervention for FSW in Baltimore, MD, including a community forum, key informant interviews with providers, and focus group discussions with FSW. FSW and providers acknowledged challenges to building rapport and establishing continuity in care settings. FSW reported low PrEP awareness, with high interest once aware. FSW and providers reported uptake barriers including perceived financial issues, lack of PrEP awareness, and mistrust of the pharmaceutical industry. Concerns were raised about substance use and daily PrEP adherence. Developing a tailored PrEP intervention for FSW necessitates multiple perspectives (e.g. FSW, service providers). Resumen La profilaxis preexposición (PrEP) es un componente vital de la prevención integral del VIH para las trabajadoras sexuales (TSF). En los Estados Unidos, hay pocas intervenciones de PrEP dirigidas a las TSF, quienes experiencian un riesgo elevado de contraer el VIH. Se realizó una investigación formativa para informar a PEARL (Promoción del empoderamiento y la reducción de riesgos), una intervención de PrEP para TSF en Baltimore, MD-la cual incluyó un foro comunitario, entrevistas con proveedores de servicios a las TSF y discusiones entre grupos focales de TSF. TSF y proveedores de servicio reconocieron los retos de mantener buenas relaciones y establecer continuidad en los servicios de salud. TSF exhibieron conocimiento limitado sobre la PrEP, pero expresaron gran interés en la PrEP después de estar informadas. TSF y los proveedores de servicios hablaron de barreras aceptando a la PrEP, incluyendo problemas financieros percibidos, falta de conocimiento sobre la PrEP y desconfianza en la industria farmacéutica. Se expresaron preocupaciones sobre el uso de sustancias y la adherencia diaria a la PrEP. El desarrollo de una intervención de PrEP personalizada para TSF requiere varias perspectivas (por ejemplo, TSF, proveedores de servicios).

Characterization of Risk Factors Among Individuals with a History of Incarceration Presenting to a Sexually Transmitted Infections Clinic: Implications for HIV and STI Prevention and Care

More than 2 million people are incarcerated in the United States with many millions more processed through correctional facilities annually. Communities impacted by incarceration are also disproportionately impacted by the HIV and sexually transmitted infection (STI) epidemics. However, relatively little is known about the behaviors that place individuals with a history of incarceration at risk for HIV/STI acquisition. We utilized clinical data from patients presenting to an STI clinic located in Providence, Rhode Island. A latent class analysis was conducted on reported HIV acquisition risk behavior and STI testing results on a total of 1129 encounters where a history of incarceration was reported. A total of three classes were identified. Class 1 (N = 187, 11%), more frequently reported 10+ sexual partners (45%), an STI diagnosis (48%) and sex while intoxicated (86%) in the past year as well as identifying as a man who has sex with other men (60%). Class 2 (N = 57, 5%) was more likely to report giving (53%) and receiving (44%) money/drugs for sex in the past year as well as a history of injecting drugs (61%) and using methamphetamine (60%). Class 3 (N = 885, 78%) most frequently reported 0-2 sexual partners (48%), identified as Black (27%), Hispanic/Latino (69%) and a man who only has sex with women (80%). Class 1 had significantly higher odds ratio (1.8, 95% confidence interval = 1.3-2.5) of testing HIV/STI positive. The results provide important insights into risk subgroups for those with a history of incarceration at risk of HIV/STI acquisition.

Violence, policing, and systemic racism as structural barriers to substance use treatment amongst women sex workers who use drugs: Findings of a community-based cohort in Vancouver, Canada (2010-2019)

BACKGROUND

Despite a high prevalence of substance use among women sex workers (SWs), rigorous social epidemiologic data on substance use treatment experiences among SWs remains limited. Given these gaps and the disproportionate burden of criminalization borne by Indigenous SWs, we evaluated (1) structural correlates of unsuccessful attempts to access substance use treatment; and (2) the interaction between policing and Indigenous ancestry on unsuccessful attempts to access treatment among SWs who use drugs.

METHODS

Prospective data were from an open community-based cohort of women SWs (2010-2019) in Vancouver, Canada. Bivariate and multivariable logistic regression with generalized estimating equations(GEE) assessed correlates of unsuccessful attempts to access treatment. A multivariable GEE confounder model examined the interaction between Indigenous ancestry and policing on unsuccessful attempts to access treatment.

RESULTS

Amongst 645 SWs who used drugs, 32.1 % reported unsuccessful attempts to access substance use treatment during the 9.5-year study. In multivariable GEE analysis, unsuccessful substance use treatment access was associated with identifying as a sexual/gender minority (AOR: 1.90, 95 %CI:1.37-2.63), opioid use (AOR: 1.43, 95 %CI: 1.07-1.91), and exposure to homelessness (AOR: 1.72; 95 %CI:1.33-2.21), police harassment (AOR: 1.48, 95 %CI:1.03-2.13), workplace violence (AOR: 1.80, 95 %CI: 1.31-2.49) and intimate partner violence (AOR: 2.11, 95 %CI:1.50-2.97). In interaction analysis, Indigenous SWs who experienced police harassment faced the highest odds of unsuccessful attempts to access substance use treatment (AOR: 2.59, 95 %CI:1.65-4.05).

CONCLUSION

Findings suggest a need to scale-up culturally-safe, trauma-informed addictions, gender-based violence, and sex worker services, alongside dismantling of systemic racism across and beyond health and addictions services.

Digital Exclusion and the Structural Barriers to Safety Strategies among Men and Non-Binary Sex Workers Who Solicit Clients Online

Background: Evidence shows that online solicitation facilitates sex workers’ ability to mitigate the risk of workplace violence. However, little is known about how end-demand sex work criminalization and the regulation of online sex work sites shape men and non-binary sex workers’ ability to maintain their own safety while soliciting services online. Methods: We conducted 21 semi-structured interviews with men and non-binary sex workers in British Columbia between 2020–2021 and examined their ability to enact safety strategies online in the context of end-demand criminalization. Analysis drew on a structural determinants of health framework. Results: Most participants emphasized that sex work is not inherently dangerous and described how soliciting services online facilitated their ability to enact personal safety strategies and remain in control of client interactions. However, participants also described how end-demand criminalization, sex work stigma, and restrictive website policies compromise their ability to solicit services online and to enact safety strategies. Conclusions: Alongside calls to decriminalize sex work, these findings emphasize the need to normalize sex work as a form of labour, promote access to online solicitation among men and non-binary sex workers, and develop standards for online sex work platforms in partnership with sex workers that prioritize sex worker safety.

Harmful Alcohol and Drug Use Is Associated with Syndemic Risk Factors among Female Sex Workers in Nairobi, Kenya

Background: Female Sex Workers (FSWs) are at high risk of harmful alcohol and other drug use. We use quantitative data to describe the prevalence of alcohol and other drug use and identify associated occupational and socio-economic risk factors, and aim to elucidate patterns of alcohol and drug use through information drawn from qualitative data. Methods: Maisha Fiti was a mixed-method longitudinal study conducted in 2019 among a random sample of FSWs in Nairobi, Kenya. We used baseline date from the behavioural−biological survey, which included the WHO Alcohol, Smoking and Substance Involvement Screening Test that measures harmful alcohol and other drug use in the past three months (moderate/high risk score: >11 for alcohol; >4 for other drugs). In-depth interviews were conducted with 40 randomly selected FSWs. Findings: Of 1003 participants, 29.9% (95%CI 27.0−32.6%) reported harmful (moderate/high risk) alcohol use, 21.5% harmful amphetamine use (95%CI 19.1−24.1%) and 16.9% harmful cannabis use (95%CI 14.7−19.2%). Quantitative analysis found that harmful alcohol, cannabis and amphetamine use were associated with differing risk factors including higher Adverse Childhood Experience (ACE) scores, street homelessness, food insecurity (recent hunger), recent violence from clients, reduced condom use, depression/anxiety and police arrest. Qualitative interviews found that childhood neglect and violence were drivers of entry into sex work and alcohol use, and that alcohol and cannabis helped women cope with sex work. Conclusions: There is a need for individual and structural-level interventions, tailored for FSWs, to address harmful alcohol and other drug use and associated syndemic risks including ACEs, violence and sexual risk behaviours.

Awareness and Utilization of HIV Testing and Prevention Services Among Female Sex Workers in Dnipro, Ukraine: Implications for Prevention Program Strengthening From the Dynamics Study

Introduction

Approximately 240,000 people live with HIV in Ukraine, concentrated among key populations, including sex workers. Non-governmental organizations (NGOs) play an important role in the funding and delivery of HIV testing and prevention services in Ukraine. These services are set within the context of national healthcare reforms as well as ongoing armed conflict. This study seeks to describe and understand the usage of HIV testing and prevention services among sex workers in the eastern Ukrainian city of Dnipro.

Methods

A cross-sectional bio-behavioral survey was administered in September 2017-March 2018 among 560 sex workers working in Dnipro. Descriptive analyses of survey data are presented alongside multivariable logistic regression models identifying factors associated with NGO awareness and HIV testing in the past 12 months; adjusted odds ratios (AOR) and 95% confidence intervals (95% CI) are reported.

Results

Sixty-two percent of respondents were aware of NGOs offering HIV services. Sixty-eight percent had tested for HIV in the past 12 months, and 51% of those who reported the location of their most recent test were tested at an NGO. Those with 5–9 years in sex work had greater odds of being aware of NGOs (AOR = 5.5, 95%CI: 3.2–9.7) and testing for HIV (AOR = 3.4, 95%CI: 2.0–6.0) compared to those new to the profession. Contact with outreach workers was strongly associated with increased odds of testing (AOR = 13.0, 95%CI: 7.0–24.0). Sex workers in “offices” (brothel-like venues) reported higher odds of testing than all other workplaces, while those in entertainment venues (AOR = 0.3, 95%CI: 0.2–0.5) and public places (AOR = 0.2, 95%CI: 0.1–0.3) reported lower rates. Receiving prevention services, such as free condoms, was associated with increased testing (AOR = 16.9, 95%CI: 9.7–29.3).

Discussion

NGOs in Dnipro, Ukraine play an important role in HIV testing and prevention for women involved in sex work. However, focused efforts should be placed on supporting access to these services for women that are newer to sex work, and those working in entertainment venues or public places. Outreach workers appear to support access to HIV prevention information and supplies and facilitate linkages to HIV testing for sex workers.

Sexual Violence and Low Rates of HIV Post-exposure Prophylaxis Access Among Female Sex Workers in Brazil

Female sex workers (FSW) are disproportionately affected by sexual violence (SV) and HIV. Social and structural barriers limit their access to post-exposure prophylaxis (PEP). Respondent-driven sampling survey in 12 Brazilian cities among 4188 FSW aimed to estimate the rates of SV and factors associated with access to PEP use among FSW who experienced SV. The prevalence of SV was 26.3% (1199). Of the 1199, 7.5% sought out healthcare and used PEP, 19% sought out healthcare, but did not use PEP, and 73.5% did not seek out healthcare after SV. Factors associated with PEP use included PEP awareness, participation in HIV/STI prevention workshops, and disclosure of FSW status in healthcare services. Although Brazil has a PEP program free of charge, it is not readily accessible, even for FSW who seek out healthcare. The development of effective strategies to link FSW to HIV preventive services is urgently needed.

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.
