Conducting Violence and Mental Health Research with Female Sex Workers during the COVID-19 Pandemic: Ethical Considerations, Challenges, and Lessons Learned from the Maisha Fiti Study in Nairobi, Kenya

Conducting violence and mental health research during the COVID-19 pandemic with vulnerable groups such as female sex workers (FSWs) required care to ensure that participants and the research team were not harmed. Potential risks and harm avoidance needed to be considered as well as ensuring data reliability. In March 2020, COVID-19 restrictions were imposed in Kenya during follow-up data collection for the Maisha Fiti study (n = 1003); hence data collection was paused. In June 2020, the study clinic was re-opened after consultations with violence and mental health experts and the FSW community. Between June 2020 and January 2021, data were collected in person and remotely following ethical procedures. A total of 885/1003 (88.2%) FSWs participated in the follow-up behavioural-biological survey and 47/47 (100%) participated in the qualitative in-depth interviews. A total of 26/885 (2.9%) quantitative surveys and 3/47 (6.4%) qualitative interviews were conducted remotely. Researching sensitive topics like sex work, violence, and mental health must guarantee study participants' safety and privacy. Collecting data at the height of COVID-19 was crucial in understanding the relationships between the COVID-19 pandemic, violence against women, and mental health. Relationships established with study participants during the baseline survey-before the pandemic-enabled us to complete data collection. In this paper, we discuss key issues involved in undertaking violence and mental health research with a vulnerable population such as FSWs during a pandemic. Lessons learned could be useful to others researching sensitive topics such as violence and mental health with vulnerable populations.

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.

Maternal health and maternal health service utilization among female sex workers: A scoping review

BACKGROUND

High proportions of female sex workers (FSWs) become pregnant and have children. Many FSWs are at increased risk of maternal health complications due to factors such as poverty, violence, and healthcare barriers. Despite this, FSWs' maternal health and use of maternal health services (MHS) receive limited attention.

OBJECTIVES

The objectives of this scoping review are to (1) synthesize existing data on FSWs' maternal health and MHS utilization and (2) assess the state of peer-reviewed literature on FSWs' maternal health in regard to methodological approaches and reported outcomes.

ELIGIBILITY CRITERIA

Included articles were peer-reviewed, published in English, and reported empirical data on FSWs for outcomes related to antenatal care, pregnancy, and labor complications, postnatal and delivery care, and/or barriers to MHS.

SOURCES OF EVIDENCE

Article searches were conducted in PubMed, Web of Science, Global Health, Sociological Abstracts, Sociological Index, PsychInfo, and CINAHL.

CHARTING METHODS

Information extracted from eligible articles included publication year, study design, location, sample size, outcome measures, and findings. The "Three Delays" model was used to synthesize findings on barriers to MHS as relevant to phase I, II, or III delays.

RESULTS

Eighteen publications met the eligibility criteria. Studies were conducted in 11 countries and primarily reported quantitative data from cross-sectional surveys. The most frequently reported outcome was antenatal care utilization (n = 14), whereas few studies reported findings related to postnatal care and breastfeeding counseling (n = 2). Across publications, there was a substantial range in the proportion of FSWs who reported accessing different types of MHS.

CONCLUSION

Literature on FSWs' maternal health is limited and heterogenous. More research is needed that specifically focuses on measuring outcomes related to FSWs' maternal health and examines associated factors. Such work can inform future research directions and public health interventions for FSWs-a population of marginalized women whose maternal health has been overlooked in existing efforts.

Police Violence: Reducing the Harms of Policing Through Public Health-Informed Alternative Response Programs

Police violence is a public health issue in need of public health solutions. Reducing police contact through public health-informed alternative response programs separate from law enforcement agencies is one strategy to reduce police perpetration of physical, emotional, and sexual violence. Such programs may improve health outcomes, especially for communities that are disproportionately harmed by the police, such as Black, Latino/a, Native American, and transgender communities; nonbinary residents; people who are drug users, sex workers, or houseless; and people who experience mental health challenges. The use of alternative response teams is increasing across the United States. This article provides a public health rationale and framework for developing and implementing alternative response programs informed by public health principles of care, equity, and prevention. We conclude with recommendations for public health researchers and practitioners to guide inquiries into policing as a public health problem and expand the use of public health-informed alternative response programs.

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.

Sexual and Reproductive Health Service Needs Associated with Underage Initiation of Selling Sex among Adult Female Sex Workers in Guinea-Bissau

OBJECTIVE

To assess the prevalence and predictors of underage initiation of selling sex among female sex workers (FSW) in Guinea-Bissau.

METHODS

505 adult FSW recruited using respondent-driven sampling were surveyed in 2017. Multivariable logistic regression was used to identify demographic, behavioral, and psychosocial characteristics associated with initiation of selling sex while underage (<18 years).

RESULTS

A total of 26.3% (133/505) of FSW started selling sex before age 18. Underage initiation of selling sex was associated with experiencing forced sex before age 18 (adjusted odds ratio (aOR): 6.74; 95% confidence interval (CI): 2.05-22.13), and never being tested for HIV (aOR: 0.43; 95% CI: 0.20-0.91). Despite having lower odds of wanting to have children or more children (aOR: 0.31; 95% CI: 0.17-0.56), FSW who started selling sex while underage had lower odds of using highly effective contraception such as implants (aOR: 0.43; 95% CI: 0.24-0.77). Among those who were ever pregnant, a lower percentage of FSW who started selling sex while underage accessed antenatal care (56.6% vs. 74.7%, p = 0.008).

CONCLUSIONS

These data suggest that early initiation of selling sex among adult FSW in Guinea-Bissau is common. Social services for youth and integrated HIV and reproductive health services are critical to address the persisting sexual and reproductive health needs of FSW who started selling sex while underage.

Formative assessment to identify perceived benefits and barriers of HIV oral self-testing among female sex workers, service providers, outreach workers, and peer educators to inform scale-up in Kenya

In Kenya, HIV prevalence estimates among female sex workers (FSWs) are almost five times higher than among women in the general population. However, only 68% of infected FSWs are aware of their HIV-positive status. We aimed to identify perceived benefits, opportunities, and barriers of HIV self-testing (HIVST) in improving testing coverage among FSWs. Twenty focus group discussions were conducted with 77 service providers, 42 peer educators (PEs) and outreach workers, and 37 FSWs attending drop-in centers (DiCEs) in four regions of Kenya. An additional 8 FSWs with HIV-negative or unknown status-completed in-depth interviews. Data were analyzed thematically. Acceptability of HIVST was high, with cited benefits including confidentiality, convenience, and ease of use. Barriers included absence of counseling, potential for inaccurate results, fear of partner reaction, possible misuse, and fear that HIVST could lead to further stigmatization. PEs and DiCEs were the preferred models for distributing HIVST kits. FSWs wanted kits made available free or at a nominal cost (100 Kenya Shillings or ∼USD 1). Linkage to confirmatory testing, the efficiency of distributing HIVST kits using peers and DiCEs, and the types and content of effective HIVST messaging require further research.

Acceptability and perceptions of HIV oral self-testing across settings: A comparative qualitative study among Dominican and Tanzanian female sex workers

Rapid oral HIV self-tests (HIVST) have potential to increase the proportion of people who know their HIV status, especially among stigmatised populations. This study was embedded in two cohorts of female sex workers (FSW) in the Dominican Republic (DR) and Tanzania. Qualitative interviews with 40 FSW were conducted to explore perceived acceptability of HIVST. Interviews were analysed using inductive and deductive thematic coding. Emergent themes were organised by socio-ecological framework levels. FSW in both settings responded positively to the ease of use of HIVST but questioned test accuracy due to the use of saliva rather than blood. FSW in the DR had a more cautious response, while women in Tanzania had favourable perceptions expressing eagerness to use it. At the individual level, themes shaping participants' interest included autonomy, HIV risk perception, and emotional well-being for those with reactive test results, and self-efficacy. At the interpersonal level, privacy, confidentiality, sex work and HIV stigma and social support were salient. Structural level themes focused on health systems including linkages to HIV treatment, provider roles, and access (cost, travel, distribution). Understanding FSW's perceptions and acceptability of HIVST is essential to its integration into health systems and programmes using a community-driven approach.

Solidarity, support and competition among communities of female and male sex workers in Mombasa, Kenya

Female and male sex workers are at elevated risk for HIV infection, psychological distress and other adverse health outcomes. It is therefore important to understand how sex workers' social relationships with one another might inform psychosocial support services for this population. We conducted semi-structured interviews to examine the formation and nature of social networks of 25 female and 25 male sex workers recruited from bars and clubs in Mombasa, Kenya. Relationships between and among female and male participants were often formed based on a mutual understanding of the challenging nature of sex work. Both groups described their relationships in terms of friendship and brotherhood/sisterhood and highlighted the following benefits of sex worker social networks: economic benefits, access to information about HIV/STIs and protection, and support against violence from clients and law enforcement agents. Social networks were often threatened by competition for clients and hence could result in conflict. However, sex workers explained that their sense of solidarity and reliance on one another for health, protection and economic well-being helped minimise conflict. The social networks of sex workers could therefore be used to leverage or optimise access to HIV prevention and care.

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

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

Understanding how social support influences peer-delivered HIV prevention interventions among Ugandan female sex workers: a case study from HIV self-testing

BACKGROUND

Female sex workers (FSWs) have tightly connected peer networks and remain at high risk of HIV acquisition. Peer delivery of HIV prevention interventions, such as HIV self-testing (HIVST), is a recommended implementation strategy for increasing intervention uptake and continuation among FSWs. We analyzed qualitative data from a peer-delivered HIVST intervention among FSWs in urban Uganda to understand the ways social support within this peer network can motivate or discourage the uptake of peer-delivered HIVST.

METHODS

Between February and April 2017, we conducted in-depth interviews (IDIs) with FSWs (n = 30) and focus group discussions (FGDs) with FSW peer educators (PEs, n = 5) finishing participation in a four-month randomized implementation trial testing models of peer-delivered HIVST in Kampala. FSW participants were ≥ 18 years old, self-reported exchanging sex for money or goods (past month) and had not recently tested for HIV (past 3 months). FSW PEs either directly distributed HIVST kits to participants or provided coupons exchangeable for HIVST kits from specified healthcare facilities. In the IDIs and FGDs, we asked participants to share their experiences receiving or delivering peer-delivered HIVST, respectively. Using a hybrid deductive and inductive coding approach, we arranged findings along the dimensions of an established social support theory: informational, instrumental, and emotional support.

RESULTS

The median age of participants was 30 years (IQR: 27-33) and PEs was 33 years (IQR: 29-37). We found that social support within FSW peer networks both motivated and discouraged uptake of peer-delivered HIVST. For example, sharing positive HIVST experiences (informational support), directly delivering HIVST kits (instrumental support), and encouraging linkage to care (emotional support) motivated HIVST uptake among FSWs. Conversely, the spread of misinformation (informational support), limited HIVST kit availability fostering mistrust of PEs (instrumental support), and fear of social exclusion following HIV status disclosure (emotional support) discouraged HIVST uptake among FSWs.

CONCLUSIONS

In Uganda, social support (e.g., informational, instrumental, and emotional support) among FSW peers can work in ways that both motivate and discourage peer-delivered intervention uptake. Future FSW peer-delivered HIV prevention interventions should be designed around the dimensions of social support within FSW peer networks to maximize initial and repeat intervention delivery and uptake.

Gender-Based Violence and Factors Associated with Victimization among Female Entertainment Workers in Cambodia: A Cross-Sectional Study

Women working in the entertainment industry are confronted with various forms of gender-based violence (GBV). However, their vulnerability remains understudied, particularly in resource-limited settings. This study aims to examine the prevalence of GBV among female entertainment workers (FEWs) in Cambodia and identify factors associated with victimization. We conducted a cross-sectional study in November 2018 for the impact evaluation of a randomized controlled trial. We used a stratified random sampling method to recruit 600 FEWs from different entertainment venues in the capital city and three other provinces. Female data collectors administered a structured questionnaire, and we performed multiple logistic regression analyses. Of the total, 60.5% had experienced a form of GBV during their lifetime; of whom, 37.5% experienced the GBV in the past 6 months. The prevalence of emotional abuse, forced substance use, physical abuse, and forced sex was 51.5%, 25.0%, 20.6%, and 2.9%, respectively. Forced substance use and forced sex were mainly perpetrated by clients, physical abuse by intimate partners, and emotional abuse by others such as entertainment establishment owners or managers. FEWs victimized by clients (relative risk ratio [RRR] = 0.19, 95% confidence interval [CI] = [0.07, 0.53]) and others (RRR = 0.11, 95% CI = [0.03, 0.44]) were less likely to be married compared with victims of intimate partner violence. Factors associated with sexual harassment were working in beer gardens (adjusted odds ratio [aOR] = 2.39, 95% CI = [1.20, 4.73]) and restaurants/cafés (aOR = 1.65, 95% CI = [1.01, 2.69]), and having higher acceptance of violence against women (aOR = 1.12, 95% CI = [1.01, 1.24]). FEWs in Cambodia experience high levels and unique forms of GBV as they are confronted with different types of perpetrators. Interventions need to be tailored to fit the specific needs of FEWs. Interventions aimed at reducing client-perpetrated violence should specifically focus on forced substance use and forced sex, while physical abuse by intimate partners should also be addressed.

How do you expect us to survive? Lamentation of female sex workers in Zimbabwe during COVID-19 lockdown

The restrictive measures taken to curb and mitigate the spread of the corona virus (COVID-19) had negative implications on the vulnerable populations. Of the latter, the most severely affected were sex workers, whose work venues and customers were locked down. This descriptive phenomenological study explored effects of COVID-19 on female sex workers in Bulawayo, Zimbabwe. Snowballing sampling was used to recruit participants. Data were collected through in-depth face-to-face individual interviews with ten female sex workers. The sample size was determined by data saturation. Colaizzi's seven-step content analysis approach was followed to guide data analysis. Rigour was ensured by adhering to Guba and Lincoln's trustworthiness criteria. The study found that the measures impacted negatively on sex workers' income, making it difficult for them to get money for food and rentals. In response, some sex workers adopted innovative entrepreneurship. Others engaged in risky sexual behaviours, further aggravating their situation emotionally and psychologically. It is recommended that the government and policy makers provide psychosocial and economic support to protect the rights of female sex workers in order to maintain the gains made in HIV response.

Mental Health and Protective Factors for Transgender and Gender-Diverse Youths Who Trade Sex: A Minnesota Statewide School-Based Study, 2019

Objectives. To describe the prevalence of sex trading by gender and by associations with mental health concerns and protective factors. Methods. We used data from 9th and 11th graders who completed the 2019 Minnesota Student Survey. The analytic sample (n = 67 806) included transgender and gender-diverse (TGD) youths and cisgender youths who reported trading sex. Data on 7 mental health measures and 4 school-related and health care-related protective factors were collected. Results. The prevalence of sex trading (5.9%) was 5 times higher among TGD students than cisgender students (1.2%). In addition, the prevalence of all mental health concerns was high among TGD students who traded sex (e.g., 75.9% reported a lifetime suicide attempt, as compared with 45.9% of cisgender students who traded sex). Fewer statistical differences were found across protective factors. When TGD students who traded sex were compared according to sex assigned at birth, no statistically significant differences were found. Conclusions. Our findings support strong calls for increased competence regarding gender and sex trading or exploitation in clinical and school-based settings to decrease health disparities among TGD youths. Public Health Implications. In this study, we have presented unique prevalence estimates of mental health disparities among TGD students in the United States who trade sex. Our results indicate that TGD students who trade sex are at risk for mental health symptoms and that sensitivity to both gender and sex trading or exploitation will be critical to meeting the needs of this group in clinical as well as school-based settings.

'It is stigma that makes my work dangerous': experiences and consequences of disclosure, stigma and discrimination among sex workers in Western Australia

Western Australia criminalises sex work whilst some other Australian jurisdictions have decriminalised the industry. This article examines the role of Western Australia's legislation in reinforcing stigma and discrimination of sex workers. It draws on stigma and discrimination-specific results from open-ended survey responses and interview data collected as part of a larger cross-sectional mixed-methods study. Experiences and/or anticipation of stigma and discrimination resulted in some sex workers concealing their involvement in sex work from family, friends and their home communities. This was a major barrier to accessing health care and protective services and impacted negatively on their mental health and wellbeing. There is a need for policy change and support to shift society's perception of sex work to that of a legitimate occupation to decrease sex workers' experiences of stigma and discrimination and improve their access to and utilisation of health care and protective services. These findings highlight the need for the decriminalisation of the Western Australian sex industry and the development of training programmes for police and healthcare workers to reduce the stigma and discrimination experienced by sex workers in these settings.

How Can We Support the Use of Oral PrEP Among Young Women who Sell Sex? A PrEP Cascade Analysis

BACKGROUND

We constructed self-reported pre-exposure prophylaxis (PrEP) cascades and explored factors associated with and barriers to PrEP use to inform efforts to support PrEP use among young women who sell sex.

METHODS

Using self-reported data from HIV-negative young women who sell sex enrolled into a cohort study using respondent-driven sampling in Zimbabwe, we constructed PrEP cascades assessing knowledge of, ever offered, ever used, and current PrEP use in 2017 and 2019. We used logistic regression to examine factors associated with PrEP use by 2019. Through qualitative interviews with 43 women enrolled in the cohort, we investigated barriers to PrEP use.

RESULTS

At enrollment, 50% of women had heard of PrEP, 12% had ever been offered PrEP, and 7% ever used PrEP. Over time, all cascade domains: 96% of women had heard of and 55% reported an active offer of PrEP. Among women retained in the study in 2019 (56%; n = 538), 34% ever took PrEP by 2019. PrEP use was associated with, at enrollment, reporting more clients in the past month (10+: 45% vs 1-3: 27% adjOR = 1.71 95% CI: 1.06 to 2.76), duration of selling sex (24% <2 years vs 38% 2-3 years; adjOR = 0.51 95% CI: 0.32 to 0.83), and having visited a female sex worker program in the past 12 months (55% vs 27%; adjOR = 2.92 95% CI: 1.91 to 4.46). Qualitative interviews revealed fear of disclosing sex work, HIV-related/ART-related stigma, and (opportunity) costs of accessing PrEP as barriers to use.

CONCLUSION

PrEP use was associated with factors known to increase HIV risk. Fear of stigma, disclosure, and supply-side barriers need to be addressed to increase women's ability to use PrEP.

The Impact of the Coronavirus Disease (COVID-19) on the Health and Social Needs of Sex Workers in Singapore

We evaluated the impact of the coronavirus disease (COVID-19) on the sex work industry and assessed how it has impacted the health and social conditions of sex workers in Singapore. We conducted a sequential exploratory mixed methods study amidst the COVID-19 pandemic from April to October 2020, including in-depth interviews with 24 stakeholders from the sex work industry and surveyor-administered structured surveys with 171 sex workers. COVID-19 had a substantial impact on sex workers' income. The illegality of sex work, stigma, and the lack of work documentation were cited as exclusionary factors for access to alternative jobs or government relief. Sex workers had experienced an increase in food insecurity (57.3%), housing insecurity (32.8%), and sexual compromise (8.2%), as well as a decrease in access to medical services (16.4%). Being transgender female was positively associated with increased food insecurity (aPR = 1.23, 95% CI [1.08, 1.41]), housing insecurity (aPR = 1.28, 95% CI [1.03, 1.60]), and decreased access to medical services (aPR = 1.74, 95% CI [1.23, 2.46]); being a venue-based sex worker was positively associated with increased food insecurity (aPR = 1.46, 95% CI [1.00, 2.13]), and being a non-Singaporean citizen or permanent resident was positively associated with increased housing insecurity (aPR = 2.59, 95% CI [1.73, 3.85]). Our findings suggest that COVID-19 has led to a loss of income for sex workers, greater food and housing insecurity, increased sexual compromise, and reduced access to medical services for sex workers. A lack of access to government relief among sex workers exacerbated such conditions. Efforts to address such population health inequities should be implemented.

Mobility for sex work and recent experiences of gender-based violence among female sex workers in Iringa, Tanzania: A longitudinal analysis

Female sex workers are highly mobile, which may influence their risk of experiencing physical and sexual violence. However, there remains a paucity of research, particularly longitudinal, from Sub-Saharan Africa exploring mobility and gender-based violence among female sex workers. To address this gap, this study examined the longitudinal relationship between work-related mobility and recent experience of physical or sexual gender-based violence from a client or partner among female sex workers in Iringa, Tanzania. A secondary data analysis was conducted using baseline and 18-month follow-up data from Project Shikamana, a community empowerment-based combination HIV prevention intervention. Responses from 387 female sex workers aged 18 years and older participating in both baseline and follow-up were analyzed. Unadjusted and adjusted Poisson regression models with robust variance estimations, accounting for clustering of female sex workers' responses over time, were fit. Final models adjusted for socio-demographic characteristics and aspects of participants' living situations and work environments. Recent physical or sexual violence from a client or partner was common (baseline: 40%; follow-up: 29%). Twenty-six percent of female sex workers at baseline, and 11% at follow-up, had recently traveled outside of Iringa for sex work. In the final adjusted longitudinal model, female sex workers recently mobile for sex work had a 25% increased risk of any recent experience of physical or sexual gender-based violence when compared with their non-mobile counterparts (adjusted incidence rate ratio: 1.25; 95% CI: 1.03-1.53; p<0.05). Interventions must identify ways-such as mobile support services, linkages and referrals to health and other social services while traveling, or the use of mobile or digital technology-to address mobile female sex workers' unique needs while traveling. Future quantitative and qualitative research is needed to understand the context of female sex workers' mobility and how and why mobility influences risk environments and experiences of gender-based violence.

Application of Integrated Behavioral Model (IBM) to measure intention to get early screening and treatment of Sexually Transmitted Infections (STIs) among HIV at- risk sub-populations in Ethiopia

Background

Sexually Transmitted Infections (STIs) increase the risk of contracting Human Immunodeficiency Virus (HIV). Hence, early screening and treatment of STIs as a behavioral practice will reduce the odds of HIV infection among at risk and vulnerable sub-populations. To that end, HIV prevention strategies need to design evidence-based interventions using behavioral models or theories to help at-risk individuals adopt early screening and treatment of STI as preventive health behavior. In this study, commercial sex workers were considered as HIV at-risk sub-populations.

Objective

Measuring to what extent that Integrated Behavioral Model constructs explain individuals' intention to practice early screening and treatment of sexually transmitted infections as healthy behavior of interest in HIV prevention.

Design

Integrated Behavioral Model (IBM) measurement survey was conducted using Respondent Driven Sampling (RDS) in six towns located in the main transport corridors of Ethiopia. Respondents' answers to model construct-based questions and intention to practice the health behavior of interest were measured using Likert Scale. Analysis was done to assess the correlation and level of association of model construct-based questions with intention to practice the preventive health behavior.

Results

Respondents' attitude explained 32%, perceived control 2%, normative influence 21%, and self-efficacy 53 % of their intention to get early screening and treatment of sexually transmitted infections.

Conclusion

Self-efficacy explained the variability of respondents' intention to get early screening and treatment of STIs most, while perceived control was the least. Hence, HIV prevention behavioral interventions targeting early screening and treatment of STIs should give high emphasis to self-efficacy.

Sexually transmitted infections and factors associated with risky sexual practices among female sex workers: A cross sectional study in a large Andean city

Background

There are limited published data on factors related to risky sexual practices (RSP) affecting sexually transmitted infections (STIs) among female sex workers (FSWs) in Ecuador.

Methods

Cross-sectional study of FSWs presenting for a consultation in a primary health care centre during 2017. A questionnaire was administered to collect information on RSP and potential risk factors including age, membership of an FSW association, self-report of previous STI diagnosis, previous treatment for suspected STI and temporary migration for sex work. Associations between RSP and potential risk factors were estimated by logistic regression. The proportion of STI was estimated from vaginal swabs by real-time PCR for four sexually transmitted pathogens (Neisseria gonorrhoeae, Trichomonas vaginalis, Chlamydia trachomatis, and Mycoplasma genitalium).

Results

Of 249 FSWs recruited, 22.5% had reported RSPs at least once during sex work. Among FSWs reporting unprotected vaginal sex in the previous three months, 25.5% had at least one other RSP type. 17.6% (95%CI 13.3–22.8) had at least one active STI. Prevalence of co-infections was 2.4% (95%CI 1.1–5.2). In multivariable analysis, RSP was associated with age (adjusted OR 1.06; 95%CI 1.02–1.10), membership of an FSWs association (aOR 3.51; 95%CI 1.60–7.72) and self-reported previous STI (aOR 3.43; 95%CI 1.28–9.17).

Conclusions

Among a population of female sex workers with high proportion of STIs, increasing age and belonging to an FSWs association was associated with a higher likelihood of engaging in RSP with clients. Engaging with FSWs organisations may reduce the burden of STI among sex workers.

Characterising HIV and STIs among transgender female sex workers: a longitudinal analysis

OBJECTIVES

Though highly vulnerable to HIV and STIs, transgender female sex workers (TFSWs) are understudied in the US HIV and STI response. This study examined the correlates of laboratory-confirmed STIs among a cohort of 62 TFSWs followed over the course of 1 year and explored associations between specimen site and self-reported engagement in insertive and receptive anal intercourse.

METHODS

Participants completed an interviewer-administered computer-assisted personal interview at baseline, 3-, 6-, 9- and 12-month visits where self-administered anal swabs and urine samples for gonorrhea, chlamydia and trichomoniasis were also collected. HIV testing was conducted at baseline, 6-month and 12-month visits.

RESULTS

Baseline HIV prevalence was 40.3% with no HIV seroconversions over follow-up. Baseline prevalence of gonorrhea, chlamydia and trichomoniasis was 9.7%, 17.7% and 14.5%, respectively. In the multivariable regression modelling, recent arrest was significantly associated with testing positive for any STI (adjusted risk ratio (RR) 1.77; 95% CI: 1.10 to 2.84). Insertive anal sex with clients was associated with increased risk of testing positive for an STI via urine specimen (RR 3.48; 95% CI: 1.14 to 10.62), while receptive anal sex was not significantly associated with specimen site.

CONCLUSION

Our findings confirm a high prevalence of STIs among TFSWs and highlight the importance of addressing structural drivers such as criminal justice involvement as well as the need to ensure screening for STIs at all anatomical sites regardless of self-reported sites of potential exposure. More research is needed to better understand HIV and STI vulnerabilities and appropriate interventions for TFSWs in the USA.

Intimate partner violence is a barrier to antiretroviral therapy adherence among HIV-positive women: Evidence from government facilities in Kenya

INTRODUCTION

Intimate Partner Violence (IPV) is linked to low engagement with HIV management services and adverse clinical outcomes, including poor ART adherence. In sub-Saharan Africa, studies on pregnant/postpartum women and transactional sex workers have produced divergent evidence regarding IPV's association with poor ART adherence. We investigate this association among a broad group of women.

METHODS

We sampled 408 HIV-positive women receiving free ART from different types of HIV clinics at government health facilities, assessing for IPV exposure by a current partner, ART adherence rate, and other factors that affect ART adherence (e.g. education, disclosure). ART adherence rates were measured using the Visual Analogue Scale (VAS); responses were dichotomised at a ≥95% cut-off. Multiple logistic regression models assessed the association between the independent variables and ART adherence.

RESULTS

The participants' mean age was 38.6 (range: 18-69 years). The majority had ever attended school (94%, n = 382), were in monogamous marriages (70%, n = 282), and had disclosed status to partners (94%, n = 380). Overall, 60% (n = 242) reported optimal ART adherence (≥ 95%) in the previous 30 days. The prevalence of IPV by the current partner was 76% (CI95 = 72-80%). Experiencing physical IPV (AOR 0.57, CI95: 0.34-0.94, p = .028), sexual IPV (AOR 0.50, CI95: 0.31-0.82, p = .005), or controlling behaviour (AOR 0.56, CI95: 0.34-0.94, p = .027) reduced the odds of achieving optimal adherence, while a higher education level and having an HIV-positive partner increased the odds.

CONCLUSION

IPV is common and is associated with suboptimal ART adherence rates among a broad group of HIV-positive women. ART programs could consider incorporating basic IPV interventions into regular clinic services to identify, monitor and support exposed women, as they might be at risk of poor ART adherence. Still, there is need for more research on how IPV affects ART adherence.

Access to HIV-prevention in female sex workers in Ukraine between 2009 and 2017: Coverage, barriers and facilitators

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

Substance Use, Mental Health Problems, and Physical and Sexual Violence Additively Increase HIV Risk Between Male Sex Workers and Their Male Clients in Northeastern United States

BACKGROUND

Male sex workers (MSW) are disproportionately affected by HIV/AIDS, with an estimated HIV prevalence in the United States of 19.3%. Existing research suggests that MSW are also at risk of adverse psychosocial problems. Cross-sectional studies of MSW have suggested that co-occurring epidemics or a "syndemic" of psychosocial problems may increase vulnerability to HIV acquisition/transmission by elevated sexual risk. To the best of our knowledge, there are no published studies examining this relationship longitudinally among MSW. This study examined how a syndemic of 6 psychosocial problems result in additive risk for condomless anal sex (CAS) with male clients among a multicity, longitudinal cohort of MSW.

SETTING

Community-based organization and health center in 2 Northeastern US cities.

METHODS

Between 2015 and 2017, 100 MSW from Boston, MA and Providence, RI completed behavioral/psychosocial surveys at baseline, 6 months, and 12months. Generalized estimating equation modeling was used to examine the prospective relationship of additive psychosocial problems and subsequent CAS with male clients, adjusting for age, site, race/ethnicity, MSW-type, and HIV serostatus.

RESULTS

Mean age = 34.7 (SD = 11.8); 62% racial/ethnic minority; and 20% HIV+. The prevalence of 6 psychosocial syndemic problems was substantial at baseline and remained high at each time point (all within the past 6 months): 74% problematic depressive symptoms, 27% polydrug use (3+ drugs, not including stimulants), 57% stimulant (methamphetamine/cocaine/crack) use, 44% hazardous drinking, 15% experienced client-specific physical/sexual violence, and 57% childhood sexual abuse. Looking at the number of psychosocial problems experienced, 7% had zero, 27% had 1, 24% had 2, 27% had 3, and 15% had 4 or more. We identified a statistically significant positive "dose-response" relationship between the number of psychosocial problems and CAS with male clients over time, with the greatest odds of engaging in CAS with a male client over follow-up among those with 4 or more psychosocial problems (adjusted odds ratio = 5.18, 95% CI: 1.61 to 16.62).

CONCLUSIONS

Internet escorts and street-based MSW are likely to experience psychosocial problems and engaging in HIV sexual risk with male clients. The accumulation of psychosocial problems additively predicted CAS with male clients in a prospective cohort of MSW. The specification of psychosocial problems presents distinct treatment targets for HIV prevention among MSW in the United States.
