RESUMEN

Importance: Emtricitabine and tenofovir disoproxil fumarate (F/TDF) for HIV preexposure prophylaxis (PrEP) is highly effective in cisgender men who have sex with men (MSM) when adherence is high (>4 doses/week). Real-world effectiveness and adherence with F/TDF for PrEP in cisgender women is less well characterized. Objective: To characterize the effectiveness of F/TDF for PrEP and its relationship with adherence in cisgender women. Design, Setting, and Participants: Data were pooled from 11 F/TDF PrEP postapproval studies conducted in 6 countries that included 6296 cisgender women aged 15 to 69 years conducted from 2012 to 2020. HIV incidence was evaluated according to adherence level measured objectively (tenofovir diphosphate concentration in dried blood spots or tenofovir concentration in plasma; n = 288) and subjectively (electronic pill cap monitoring, pill counts, self-report, and study-reported adherence scale; n = 2954) using group-based trajectory modeling. Exposures: F/TDF prescribed orally once a day. HIV incidence was analyzed in subgroups based on adherence trajectory. Main Outcomes and Measures: HIV incidence. Results: Of the 6296 participants, 46% were from Kenya, 28% were from South Africa, 21% were from India, 2.9% were from Uganda, 1.6% were from Botswana, and 0.8% were from the US. The mean (SD) age at PrEP initiation across all studies was 25 (7) years, with 61% of participants being younger than 25 years. The overall HIV incidence was 0.72 per 100 person-years (95% CI, 0.51-1.01; 32 incident HIV diagnoses among 6296 participants). Four distinct groups of adherence trajectories were identified: consistently daily (7 doses/week), consistently high (4-6 doses/week), high but declining (from a mean of 4-6 doses/week and then declining), and consistently low (less than 2 doses/week). None of the 498 women with consistently daily adherence acquired HIV. Only 1 of the 658 women with consistently high adherence acquired HIV (incidence rate, 0.13/100 person-years [95% CI, 0.02-0.92]). The incidence rate was 0.49 per 100 person-years (95% CI, 0.22-1.08) in the high but declining adherence group (n = 1166) and 1.27 per 100 person-years (95% CI, 0.53-3.04) in the consistently low adherence group (n = 632). Conclusions and Relevance: In a pooled analysis of 11 postapproval studies of F/TDF for PrEP among cisgender women, overall HIV incidence was 0.72 per 100 person-years; individuals with consistently daily or consistently high adherence (4-6 doses/week) to PrEP experienced very low HIV incidence.

RESUMEN

BACKGROUND: Previous WHO guidance on tenofovir disoproxil fumarate-based oral pre-exposure prophylaxis (PrEP) suggests measuring creatinine levels at PrEP initiation and regularly afterwards, which might represent barriers to PrEP implementation and uptake. We aimed to systematically review published literature on kidney toxicity among tenofovir disoproxil fumarate-based oral PrEP users and conducted an individual participant data meta-analysis (IPDMA) on kidney function among PrEP users in a global implementation project dataset. METHODS: In this systematic review and meta-analysis we searched PubMed up to June 30, 2021, for randomised controlled trials (RCTs) or cohort studies that reported on graded kidney-related adverse events among oral PrEP users (tenofovir disoproxil fumarate-based PrEP alone or in combination with emtricitabine or lamivudine). We extracted summary data and conducted meta-analyses with random-effects models to estimate relative risks of grade 1 and higher and grade 2 and higher kidney-related adverse events, measured by elevated serum creatinine or decline in estimated creatinine clearance or estimated glomerular filtration rate. The IPDMA included (largely unpublished) individual participant data from 17 PrEP implementation projects and two RCTs. Estimated baseline creatinine clearance and creatinine clearance change after initiation were described by age, gender, and comorbidities. We used random-effects regressions to estimate the risk in decline of creatinine clearance to less than 60 mL/min. FINDINGS: We identified 62 unique records and included 17 articles reporting on 11 RCTs with 13 523 participants in meta-analyses. PrEP use was associated with increased risk of grade 1 and higher kidney adverse events (pooled odds ratio [OR] 1·49, 95% CI 1·22-1·81; I2=25%) and grade 2 and higher events (OR 1·75, 0·68-4·49; I2=0%), although the grade 2 and higher association was not statistically significant and events were rare (13 out of 6764 in the intervention group vs six out of 6782 in the control group). The IPDMA included 18 676 individuals from 15 countries (1453 [7·8%] from RCTs) and 79 (0·42%) had a baseline estimated creatinine clearance of less than 60 mL/min (increasing proportions with increasing age). Longitudinal analyses included 14 368 PrEP users and 349 (2·43%) individuals had a decline to less than 60 mL/min creatinine clearance, with higher risks associated with increasing age and baseline creatinine clearance of 60·00-89·99 mL/min (adjusted hazard ratio [aHR] 8·49, 95% CI 6·44-11·20) and less than 60 mL/min (aHR 20·83, 12·83-33·82). INTERPRETATION: RCTs suggest that risks of kidney-related adverse events among tenofovir disoproxil fumarate-based oral PrEP users are increased but generally mild and small. Our global PrEP user analysis found varying risks by age and baseline creatinine clearance. Kidney function screening and monitoring might focus on older individuals, those with baseline creatinine clearance of less than 90 mL/min, and those with kidney-related comorbidities. Less frequent or optional screening among younger individuals without kidney-related comorbidities may reduce barriers to PrEP implementation and use.

RESUMEN

PURPOSE OF REVIEW: To review the impact of the COVID-19 pandemic and its public health response on key populations at risk of HIV infection, with a focus on sex workers. RECENT FINDINGS: Since last year several groups have documented how the COVID-19 pandemic has impacted the livelihoods and health of sex workers. We focus on case studies from Kenya, Ukraine, and India and place these in the broader global context of sex worker communities, drawing on common themes that span geographies. COVID-19-associated lockdowns have significantly disrupted sex work, leading to economic and health challenges for sex workers, ranging from HIV-related services to mental health and exposure to violence. Several adaptations have been undertaken by sex workers and frontline workers, including migration, a move to mobile services, and struggling to find economic supports. Strengthening community-based responses for future pandemics and other shocks is critical to safeguard the health of marginalized populations.

RESUMEN

Decline in new HIV infections in the Asia-Pacific region (APAC) continues to be slow, emphasising the importance of scaling up new HIV prevention strategies, such as pre-exposure prophylaxis (PrEP). To help inform PrEP rollout in APAC, we conducted a rapid review of published literature on PubMed from 2015 to 2020, to assess feasibility, implementation strategies, cost-effectiveness, and availability of national policies and guidelines; for the latter, we also did an expanded Internet search. This review focussed on nine countries contributing >95% of new infections in this region. A total of 36 PrEP-related studies conducted among men who have sex with men, female sex workers, and transgender women were included, of which 29 were quantitative, six were qualitative and one was a mixed-method study. Most of the studies have addressed the availability and acceptability of PrEP, whereas cost-effectiveness of any approach was assessed by limited studies. Limited published information was available about national PrEP policies and guidelines; of the selected nine countries, five have adopted the recommended World Health Organization PrEP policy of which four have integrated it in their national HIV response. HIV risk perception concerns about safety, side-effects, stigma, and affordability were major challenges to PrEP acceptance. Community-based implementation has the potential to address these. Limited evidence suggested merging PrEP implementation with ongoing targeted intervention and treatment programs could be a cost-effective approach. To stem the epidemic, newer effective prevention strategies, like PrEP, should be urgently adopted within the context of combination HIV prevention approaches.

RESUMEN

We illustrate the lively existence of the notion of success in the unfolding of a PrEP project led by a sex worker organization in India. In what we call the "search for success," particular attention is placed on the role that care plays among sex workers guiding the project. Drawing on our ethnographic work, we highlight how the search for success underlines particular affective dispositions that are underscored by overlapping temporal registers: in the early stages of fostering adherence; when project fatigue sets in; and as the project draws to a close, in the anticipation of what comes next for the organization.

RESUMEN

Global health policy-makers have called for demonstration projects to better understand pre-exposure prophylaxis' (PrEP) effectiveness across geographies and populations. Ashodaya, a sex worker collective, initiated a PrEP project in Mysore, India. We conducted a project ethnography to explore the role that community participation played within the project. Although the project proved immensely successful in terms of retention and adherence, to explain these findings we point towards Ashodaya's history of collectivisation around sexual health-a history of community action that has given rise to new spaces of belonging and accumulated knowledges that became instrumental in the formulation of strategies to confront anticipated challenges during the project. These strategies included: (1) the participation of community leaders as the first participants to take PrEP, followed by the sharing of their experiences through testimonials to their peers; (2) the endorsement of PrEP among community leaders living with HIV, to avoid social divisions around HIV status; and (3) ongoing community-level support from outreach workers that went beyond administering PrEP to address the various needs of the community. These community-led approaches demonstrate that communities hold key insights into the delivery of clinically-oriented interventions, suggesting the vital role they continue to play in planning and implementing new prevention technologies.

RESUMEN

Sex workers have been one of the marginalized groups that have been particularly affected by India's stringent lockdown in response to the coronavirus disease 2019 (COVID-19) pandemic. The sudden loss of livelihood and lack of access to health care and social protection intensified the vulnerabilities of sex workers, especially those living with HIV. In response, Ashodaya Samithi, an organization of more than 6000 sex workers, launched an innovative programme of assistance in four districts in Karnataka. Since access to antiretroviral therapy (ART) was immediately disrupted, Ashodaya adapted its HIV outreach programme to form an alternative, community-led system of distributing ART at discreet, private sites. WhatsApp messaging was used to distribute information on accessing government social benefits made available in response to the COVID-19 pandemic. Other assistance included advisory messages posted in WhatsApp groups to raise awareness, dispel myths and mitigate violence, and regular, discreet phone check-ins to follow up on the well-being of members. The lessons learnt from these activities represent an important opportunity to consider more sustainable approaches to the health of marginalized populations that can enable community organizations to be better prepared to respond to other public health crises as they emerge.

RESUMEN

We explored general health and psychosocial characteristics among male sex workers and other men who have sex with men in Nairobi, Kenya. A total of 595 MSM/MSW were recruited into the study. We assessed group differences among those who self-reported HIV positive (SR-HIVP) and those who self-reported HIV negative (SR-HIVN) and by affinity group membership. Quality of life among SR-HIVP participants was significantly worse compared to SR-HIVN participants. Independent of HIV status and affinity group membership, participants reported high levels of hazardous alcohol use, harmful substance use, recent trauma and childhood abuse. The overall sample exhibited higher prevalence of moderate to severe depressive symptoms compared to the general population. Quality of life among participants who did not report affinity group membership (AGN) was significantly worse compared to participants who reported affinity group membership (AGP). AGN participants also reported significantly lower levels of social support. Membership in affinity groups was found to influence health seeking behaviour. Our findings suggest that we need to expand the mainstay biomedical and comorbidity focused research currently associated with MSM/MSW. Moreover, there are benefits to being part of MSM/MSW organisations and these organisations can potentially play a vital role in the health and well-being of MSM/MSW.

RESUMEN

To inform PrEP roll out, Ashodaya Samithi, a sex workers' collective, conducted a community-led prospective demonstration project among female sex workers in Mysore and Mandya, India. Following a community preparedness phase and pre-screening, participants were recruited for clinical screening and enrolment, provided PrEP as part of combination HIV prevention, and followed for 16 months. Adherence was measured by self-reported pill intake and by tenofovir blood level testing among a subset of participants. Of the 647 participants enrolled, 640 completed follow-up. Condom use remained stable and no HIV seroconversions occurred. Self-reported daily PrEP intake over the last month was 97.97% at the end of the study. Tenofovir blood levels >40 ng/mL (consistent with steady state dosing) were detected among 80% (n = 68/85) and 90.48% (n = 76/84) of participants at month 3 and 6, respectively. Our study holds important insights for rolling out PrEP in community settings as part of targeted HIV prevention interventions.

RESUMEN

Persisting inequities in maternal health pose a particular burden for marginalised populations such as sex workers. However, current literature on pregnancy and sex work is limited to mostly quantitative studies focusing on contraception use, unplanned and/or undesired pregnancies and unsafe abortions. Additionally, emphasis has been placed on the prevention, treatment and care of STIs and HIV with less attention accorded to women's pregnancy desires and implications to work. In this paper, we explore sex workers' conflicted experiences surrounding pregnancy, parenthood, and work. Forty-six women participated in in-depth interviews as part of a qualitative exploratory study conducted in close collaboration with a sex worker collective in the city of Mysore (South India). Our analysis focuses on women's pragmatic responses to pregnancy desires, workplace challenges during and after pregnancy, strategies for managing risk and approaches to managing work and childcare. We show that women confront various intersecting challenges with respect to pregnancy and sex work. Women's complex decision-making balances multiple considerations while highlighting the temporal dimension of pragmatism as women respond not only to the immediacy of an encounter but also in anticipation of a better future.

RESUMEN

Ashodaya Samithi, an organization run by and for female, male, and transgender sex workers in Mysore, India, has worked since 2004 to prevent sexually transmitted infection (STI)/human immunodeficiency virus (HIV) transmission and improve HIV cascade outcomes. We reviewed published and programmatic data, including measures of coverage, uptake, utilization and retention, and relate STI/HIV outcomes to evolving phases of community mobilization. Early interventions designed "for" sex workers mapped areas of sex work and reached half the sex workers in Mysore with condoms and STI services. By late 2005, when Ashodaya Samithi registered as a community-based organization, interventions were implemented "with" sex workers as active partners. Microplanning was introduced to enable peer educators to better organize and monitor their outreach work to reach full coverage. By 2008, programs were run "by" sex workers, with active community decision making. Program data show complete coverage of community outreach and greater than 90% clinic attendance for quarterly checkups by 2010. Reported condom use with last occasional client increased from 65% to 90%. Surveys documented halving of HIV and syphilis prevalence between 2004 and 2009, while gonorrhoea declined by 80%. Between 2005 and 2013, clinic checkups tripled, whereas the number of STIs requiring treatment declined by 99%. New HIV infections also declined, and Ashodaya achieved strong cascade outcomes for HIV testing, antiretroviral treatment linkage, and retention. Program performance dropped markedly during several periods of interrupted funding, then rebounded when restored. Ashodaya appear to have achieved rapid STI/HIV control with community-led approaches including microplanning. Available data support near elimination of curable STIs and optimal cascade outcomes.

RESUMEN

INTRODUCTION: Women in developing countries continue to face barriers to accessing sexual and reproductive health (SRH) services, with marginalized women facing increased challenges to accessing care. The Diagonal Interventions to Fast-Forward Enhanced Reproductive Health (DIFFER) project implemented a package of interventions for female sex workers and women from the general population which integrated horizontal health services for the general population with existing vertical targeted interventions aimed at sex workers with an aim to improve SRH and HIV services. We present an outcome evaluation of the DIFFER project in terms of uptake rates for SRH services among sex workers in Mysore, India. METHODS: Ashodaya Samithi, a sex worker-led organization, implemented the DIFFER strategy through their community-based clinic and a Well Women Clinic (WWC), established at a partner private hospital that provided SRH services for women living with HIV. Mixed methods were used to evaluate the intervention that included a baseline (2012-13) and end of project (2015-16) cross sectional surveys (CSS), focus group discussions (FGDs), key informant interviews, and analysis of service statistics from 2013-2016. RESULTS: The CSS found that condom use, STI testing, and treatment were high before, and throughout the intervention; cervical cancer screening and treatment increased significantly, from 11.5% to 56% (aOR 9.85, p<0.001) and HIV testing in the last 3 months increased from 26.3% to 73.3% (aOR 7.25, p<0.001). The proportion of sex workers using any SRH service in the past year doubled from 25.7% to 51.4% (aOR 2.91, p<0.001). Service statistics showed similar trends. The FGDs and key informant interviews showed that women and stakeholders held high levels of satisfaction with the strategy, and affirmed potential for scale up. CONCLUSION: The DIFFER strategy demonstrated that SRH service uptake can occur in conjuction with HIV services offered to sex workers. This model of integrated service delivery has been accepted by policy makers and needs further analysis for scaling up.

RESUMEN

PURPOSE OF REVIEW: We review the recent evidence regarding strategies for engaging sex workers in HIV prevention and care programs. We searched Pub Med on 19 March 2019 using terms 'Sex Work' And 'HIV infections'. Our search was limited to articles published since 2017. RECENT FINDINGS: Community empowerment approaches where sex workers work collaboratively to address their specific priorities and concerns, including those beyond HIV, are those most likely to meaningfully engage sex workers. Community-driven programs that combine structural, behavioral and biomedical approaches can facilitate improved HIV outcomes by tackling barriers to uptake and retention of services along all steps in the prevention and care cascades. Microplanning, network-based recruitment and mobile-phone interventions can also help reach and support sex workers to mobilize and to engage with a range of services. Sex worker-led groups and initiatives including economic strengthening and community drug refill groups can both build social cohesion and address structural barriers to HIV outcomes including financial insecurity. Interventions which focus narrowly on increasing uptake of specific steps in prevention and care cascades outside the context of broader community empowerment responses are likely to be less effective. SUMMARY: Comprehensive, community-driven approaches where sex workers mobilize to address their structural, behavioral and biomedical priorities work across HIV prevention and treatment cascades to increase uptake of and engagement with prevention and care technologies and promote broader health and human rights. These interventions need to be adequately supported and taken to scale.

RESUMEN

Pre-exposure prophylaxis (PrEP) has emerged as a new HIV prevention strategy. A series of demonstration projects were conducted to explore the use of PrEP outside of clinical trial settings. Learning from the failures in community consultation and involvement in early oral tenofovir trials, these PrEP projects attempted to better engage communities and create spaces for community involvement in the planning and roll out of these projects. We briefly describe the community engagement strategies employed by seven Bill & Melinda Gates Foundation-funded PrEP demonstration projects and the lessons these projects offer for community engagement in PrEP implementation.

RESUMEN

BACKGROUND: Female sex workers (FSWs) are extremely vulnerable to adverse sexual and reproductive health (SRH) outcomes. To mitigate these risks, they require access to services covering not only HIV prevention but also contraception, cervical cancer screening and sexual violence. To develop context-specific intervention packages to improve uptake, we identified gaps in service utilization in four different cities. METHODS: A cross-sectional survey was conducted, as part of the baseline assessment of an implementation research project. FWSs were recruited in Durban, South Africa (n = 400), Mombasa, Kenya (n = 400), Mysore, India (n = 458) and Tete, Mozambique (n = 308), using respondent-driven sampling (RDS) and starting with 8-16 'seeds' identified by the peer educators. FSWs responded to a standardised interviewer-administered questionnaire about the use of contraceptive methods and services for cervical cancer screening, sexual violence and unwanted pregnancies. RDS-adjusted proportions and surrounding 95% confidence intervals were estimated by non-parametric bootstrapping, and compared across cities using post-hoc pairwise comparison tests with Dunn-Sidák correction. RESULTS: Current use of any modern contraception ranged from 86.2% in Tete to 98.4% in Mombasa (p = 0.001), while non-barrier contraception (hormonal, IUD or sterilisation) varied from 33.4% in Durban to 85.1% in Mysore (p < 0.001). Ever having used emergency contraception ranged from 2.4% in Mysore to 38.1% in Mombasa (p < 0.001), ever having been screened for cervical cancer from 0.0% in Tete to 29.0% in Durban (p < 0.001), and having gone to a health facility for a termination of an unwanted pregnancy from 15.0% in Durban to 93.7% in Mysore (p < 0.001). Having sought medical care after forced sex varied from 34.4% in Mombasa to 51.9% in Mysore (p = 0.860). Many of the differences between cities remained statistically significant after adjusting for variations in FSWs' sociodemographic characteristics. CONCLUSION: The use of SRH commodities and services by FSWs is often low and is highly context-specific. Reasons for variation across cities need to be further explored. The differences are unlikely caused by differences in socio-demographic characteristics and more probably stem from differences in the availability and accessibility of SRH services. Intervention packages to improve use of contraceptives and SRH services should be tailored to the particular gaps in each city.

RESUMEN

BACKGROUND: HIV prevalence among female sex workers (FSWs) in India remains well above the national average. Pre-exposure prophylaxis (PrEP), a new HIV prevention technology, may help to reduce HIV incidence, but there is a dearth of research that can inform the potential scale-up of PrEP in India. In partnership with Ashodaya Samithi, a local sex worker collective, we conducted a feasibility study to assess acceptance of a planned PrEP demonstration project, willingness to use PrEP, and recommendations for project roll-out among FSWs in southern Karnataka. METHODS: From January-April 2015, 6 focus group discussions, 47 in-depth interviews, and 427 interviewer-administered questionnaires were completed by female sex workers. All participants were 18 years of age or older and practiced sex work. Qualitative data were coded for key themes and emergent categories. Univariate descriptive analysis was employed to summarise the quantitative data. RESULTS: Qualitative. PrEP was described as an exciting new prevention technology that places control in the hands of FSWs and provides a "double safety" in combination with condom use. Participants expressed agreement that women who may experience more HIV risk in their occupational environments should be prioritized for enrollment into a demonstration project. Quantitative. 406 participants (95%) expressed interest in PrEP. Participants prioritized the inclusion of FSWs under the age of 25 (79%), those who do not use condoms when clients offer more money (58%), who do not consistently use condoms with regular partners (57%), who drink alcohol regularly (49%), and who do not use condoms consistently with clients (48%). DISCUSSION: This feasibility study indicated strong interest in PrEP and a desire to move forward with the demonstration project. Participants expressed their responses in terms of public health discourses surrounding risk, pointing to the importance of situating PrEP scale up within the trusted spaces of community-based organizations as a means of supporting PrEP uptake and adherence.

RESUMEN

OBJECTIVE: To identify gaps in the use of HIV prevention and care services and commodities for female sex workers, we conducted a baseline cross-sectional survey in four cities, in the context of an implementation research project aiming to improve use of sexual and reproductive health services. METHODS: Using respondent-driven sampling, 400 sex workers were recruited in Durban, 308 in Tete, 400 in Mombasa and 458 in Mysore and interviewed face-to-face. RDS-adjusted proportions were estimated by nonparametric bootstrapping and compared across cities using post hoc pairwise comparison. RESULTS: Condom use with last client ranged from 88.3% to 96.8%, ever female condom use from 1.6% to 37.9%, HIV testing within the past 6 months from 40.5% to 70.9%, receiving HIV treatment and care from 35.5% to 92.7%, care seeking for last STI from 74.4% to 87.6% and having had at least 10 contacts with a peer educator in the past year from 5.7% to 98.1%. Many of the differences between cities remained statistically significant (P < 0.05) after adjusting for differences in FSWs' socio-demographic characteristics. CONCLUSION: The use of HIV prevention and care by FSWs is often insufficient and differed greatly between cities. Differences could not be explained by variations in socio-demographic sex worker characteristics. Models to improve use of condoms and HIV prevention and care services should be tailored to the specific context of each site. Programmes at each site must focus on improving availability and uptake of those services that are currently least used.

RESUMEN

BACKGROUND: A baseline cross-sectional survey among female sex workers (FSWs) was conducted in four cities within the context of an implementation research project aiming to improve FSWs' access to HIV, and sexual and reproductive health (SRH) services. The survey measured where FSWs seek HIV/SRH care and what motivates their choice. METHODS: Using respondent-driven sampling (RDS), FWSs were recruited in Durban, South Africa (n = 400), Tete, Mozambique (n = 308), Mombasa, Kenya (n = 400) and Mysore, India (n = 458) and interviewed. RDS-adjusted proportions were estimated by non-parametric bootstrapping, and compared across cities using post-hoc pairwise comparison tests. RESULTS: Across cities, FSWs most commonly sought care for the majority of HIV/SRH services at public health facilities, most especially in Durban (ranging from 65% for condoms to 97% for HIV care). Services specifically targeting FSWs only had a high coverage in Mysore for STI care (89%) and HIV testing (79%). Private-for-profit clinics were important providers in Mombasa (ranging from 17% for STI care and HIV testing to 43% for HIV care), but not in the other cities. The most important reason for the choice of care provider in Durban and Mombasa was proximity, in Tete 'where they always go', and in Mysore cost of care. Where available, clinics specifically targeting FSWs were more often chosen because of shorter waiting times, perceived higher quality of care, more privacy and friendlier personnel. CONCLUSION: The place where care is sought for HIV/SRH services differs substantially between cities. Targeted services have limited coverage in the African cities compared to Mysore. Convenience appears more important for choosing the place of care than aspects of quality of care. The best model to improve access, linking targeted interventions with general health services, will need to be tailored to the specific context of each city.

RESUMEN

PURPOSE: Men and transgender women who have sex with men (MTWSM) continue to be an at-risk population for human immunodeficiency virus (HIV) infection in India. Identification of risk factors and determinants of HIV infection is urgently needed to inform prevention and intervention programming. METHODS: Data were collected from cross-sectional biological and behavioral surveys from four districts in Karnataka, India. Multivariable logistic regression models were constructed to examine factors related to HIV infection. Sociodemographic, sexual history, sex work history, condom practices, and substance use covariates were included in regression models. RESULTS: A total of 456 participants were included; HIV prevalence was 12.4%, with the highest prevalence (26%) among MTWSM from Bellary District. In bivariate analyses, district (P = 0.002), lack of a current regular female partner (P = 0.022), and reported consumption of an alcoholic drink in the last month (P = 0.004) were associated with HIV infection. In multivariable models, only alcohol use remained statistically significant (adjusted odds ratios: 2.6, 95% confidence intervals: 1.2-5.8; P = 0.02). CONCLUSION: The prevalence of HIV continues to be high among MTWSM, with the highest prevalence found in Bellary district.

RESUMEN

Under the umbrella of the Bill and Melinda Gates-funded HIV initiative in India, the Mysore-based sex workers' (SWs) collective Ashodaya Samithi focused on improving its members' living and working conditions through community-led structural interventions, including community mobilisation, advocacy, peer-led support, and health promotional activities. Based on four months of ethnographic fieldwork, this article examines the care and support activities of one of its sub-wings, Ashraya, which specifically focuses on people living with HIV and AIDS (PLHIV). We first discuss the stigma-related perceptions and experiences of participants in relation to health-care settings and work environment, families and communities, and within varied HIV support networks. We then explore how Ashraya's community-led interventions attempt to challenge the structural forces feeding on and creating stigma. We argue that the current policy focus on the involvement of SWs' collectives in sexually transmitted infection (STI) prevention in India is rather limited and should be expanded along the continuum of care and support offered to PLHIV. As suggested in this paper, SWs' organisations may have greater potential to contribute to more than STI prevention work, both within and outside their communities, than currently recognised.
