RESUMO

BACKGROUND: The design of HIV prevention programs for adolescent girls and young women (AGYW) are informed by data on who is at highest risk and where they can be reached. Places (hotspots) associated with selling sex are an established outreach strategy for sex work (SW) programs but could be used to reach other AGYW at high risk. SETTING: This study took place in Mombasa, Kenya. METHODS: We conducted a cross-sectional, bio-behavioural survey among (N = 1193) sexually active AGYW aged 14-24 years recruited at hotspots. We compared HIV prevalence by subgroup (SW; transactional sex, TS; and non-transactional sex), stratified by hotspot type (venues and nonvenues). We examined whether associations between HIV prevalence and hotspot/subgroup remained after adjustment for individual-level risk factors, and estimated HIV prevalence ratio with and without adjustment for these individual-level factors. RESULTS: Overall HIV prevalence was 5.6%, 5.3% in venues and 7.3% in nonvenues. Overall SW HIV prevalence was 2-fold higher than among participants engaged in nontransactional sex. After adjusting for age and individual-level risk factors, HIV prevalence was 2.72 times higher among venue-based SWs (95% confidence interval: 1.56 to 4.85) and 2.11 times higher among nonvenue AGYW not engaged in SW (95% confidence interval: 0.97 to 4.30) compared with venue-based AGYW not engaged in SW. CONCLUSION: AGYW who sell sex remain at high risk of HIV across types of hotspots. The residual pattern of elevated HIV burden by AGWY subgroup and hotspot type suggests that unmeasured, network-level factors underscore differential risks. As such, hotspots constitute a "place" to reach AGYW at high risk of HIV.

RESUMO

Little is known about the impact of military conflict on sex work from the perspective of sex workers. We attempt to explore the meaning of conflict on sex work by asking women about the changes that they have experienced in their lives and work since the beginning of the 2014 military conflict in eastern Ukraine. The findings in this article are based on qualitative interviews with 43 cisgender women living and practicing sex work in Dnipro, eastern Ukraine. Our analysis highlights the meanings that sex workers have linked to the conflict, with financial concerns emerging as a dominant theme. The conflict therefore functions as a way of understanding changing economic circumstances with both individual and broader impacts. By better understanding the meaning of conflict as expressed by sex workers, we can begin to adapt our response to address emerging, and unmet, needs of the community.

RESUMO

BACKGROUND: Armed conflict erupted in eastern Ukraine in 2014 and still continues. This conflict has resulted in an intensification of poverty, displacement and migration, and has weakened the local health system. Ukraine has some of the highest rates of HIV and Hepatitis C (HCV) in Europe. Whether and how the current conflict, and its consequences, will lead to changes in the HIV and HCV epidemic in Ukraine is unclear. Our study aims to characterize how the armed conflict in eastern Ukraine and its consequences influence the pattern, practice, and experience of sex work and how this affects HIV and HCV rates among female sex workers (FSWs) and their clients. METHODS: We are implementing a 5-year mixed methods study in Dnipro, eastern Ukraine. Serial mapping and size estimation of FSWs and clients will be conducted followed by bio-behavioral cross-sectional surveys among FSWs and their clients. The qualitative component of the study will include in-depth interviews with FSWs and other key stakeholders and participant diaries will be implemented with FSWs. We will also conduct an archival review over the course of the project. Finally, we will use these data to develop and structure a mathematical model with which to estimate the potential influence of changes due to conflict on the trajectory of HIV and HCV epidemics among FSW and clients. DISCUSSION: The limited data that exists on the effect of conflict on disease transmission provides mixed results. Our study will provide rigorous, timely and context-specific data on HIV and HCV transmission in the setting of conflict. This information can be used to inform the design and delivery of HIV and HCV prevention and care services.

RESUMO

BACKGROUND: Program Science is an iterative, multi-phase research and program framework where programs drive the scientific inquiry, and both program and science are aligned towards a collective goal of improving population health. DISCUSSION: To achieve this, Program Science involves the systematic application of theoretical and empirical knowledge to optimize the scale, quality and impact of public health programs. Program Science tools and approaches developed for strategic planning, program implementation, and program management and evaluation have been incorporated into HIV and sexually transmitted infection prevention programs in Kenya, Nigeria, India, and the United States. CONCLUSION: In this paper, we highlight key scientific contributions that emerged from the growing application of Program Science in the field of HIV and STI prevention, and conclude by proposing future directions for Program Science.

RESUMO

Despite decreased rates of HIV infection in Winnipeg, syphilis incidence continues to rise. Communities of men who have sex with men shoulder much of this burden of illness. This qualitative study aimed to better understand the co-evolution of HIV and syphilis in Winnipeg through a series of interviews with gay men. Eighteen individuals were recruited through advertising in sexual health centres and through subsequent snowball sampling. Thematic interpretive analysis and inductive reasoning were used to find individual and shared group meanings. We found that HIV formed the contextual ground on which sexual decision-making was made, with three main themes emerging during interviews: 1) bacterial STI transience being contrasted against HIV permanence; 2) syphilis being 'dirty' versus HIV carrying significant stigma, though being spared the label of uncleanliness; and 3) the role of pleasure and intimacy in sexual health decision-making. Based on these findings, we recommend further exploration to develop more effective strategies around syphilis prevention, in particular with regards to the longer-term illness ramifications and its relationship to HIV transmission.

RESUMO

OBJECTIVES: Men who have sex with men (MSM) are at high risk of HIV-1 acquisition and transmission, yet there remains limited data in the African context, and for men who sell sex to men (MSM SW) in particular. METHODS: We enrolled 507 male sex workers in a Nairobi-based prospective cohort study during 2009-2012. All participants were offered HIV/STI screening, counselling and completed a baseline questionnaire. RESULTS: Baseline HIV prevalence was 40.0% (95% CI 35.8% to 44.3%). Prevalent HIV infection was associated with age, less postsecondary education, marijuana use, fewer female partners and lower rates of prior HIV testing. Most participants (73%) reported at least two of insertive anal, receptive anal and insertive vaginal sex in the past 3 months. Vaginal sex was reported by 37% of participants, and exclusive MSM status was associated with higher HIV rates. Condom use was infrequent, with approximately one-third reporting 100% condom use during anal sex. HIV incidence was 10.9 per 100 person-years (95% CI 7.4 to 15.6). Predictors of HIV risk included history of urethral discharge (aHR 0.29, 95% CI 0.08 to 0.98, p=0.046), condom use during receptive anal sex (aHR 0.05, 95% CI 0.01 to 0.41, p=0.006) and frequency of sex with male partners (aHR 1.33/sex act, 95% CI 1.01 to 1.75, p=0.04). CONCLUSIONS: HIV prevalence and incidence were extremely high in Nairobi MSM SW; a combination of interventions including increasing condom use, pre-exposure prophylaxis and access to effective treatment is urgently needed to decrease HIV transmission in this key population.

RESUMO

BACKGROUND: Interventions designed to prevent HIV and STIs in female sex-workers (FSWs) reach women after they formally enter the sex-trade. We aimed to characterize the pattern of sexual behaviour among FSWs from first-sex to when they identify as sex-workers (transition period) in a region with traditional (historically characterized by dedication into sex-work at first-sex) and non-traditional forms of sex-work. METHODS: We conducted a cross-sectional survey of 246 traditional and 765 non-traditional FSWs across three districts in Karnataka, India. We performed univariate and multivariate logistic regression to profile FSWs most likely to engage in a commercial first-sex before identifying as a sex-worker. Sexual life-course patterns were distinguished using univariate and multivariate linear regression based on key events associated with length of transition period. RESULTS: Overall, 266 FSWs experienced a commercial first-sex, of whom 45.9% (95% CI: 38.2,53.7) continued a long-term relationship with the first partner. In adjusted analysis, traditional FSWs were more likely to experience a commercial first-sex (AOR 52.5, 95% CI: 27.4,100.7). The average transition time was 8.8 years (SD 3.9), but there was considerable variability between respondents. Among women who experienced a commercial first-sex, a slower transition was independently associated with non-traditional sex-work, the presence of long-term partnerships during the transition period, and ongoing partnerships at time of entry into sex-work. In the absence of a commercial first-sex, a faster transition was associated with traditional sex-work and the dissolution of long-term partnerships, while a slower transition was associated with the presence of long-term partnerships and widowhood. Only 18.5% (95% CI: 12.7,26.2) and 47.3% (95% CI: 32.7,62.3) of women reported 'always' condom use with their long-term and occasional partners during the transition period, respectively. CONCLUSIONS: FSWs identify as sex-workers several years after becoming sexually active, even when the first-sex is commercial in nature. Long-term partnerships are common after a commercial first-sex, and are associated with a delay in formally entering the sex-trade. The findings call for a better understanding of HIV/STI risk before FSWs identify as sex-workers, and an adaptive programme to reach this period of vulnerability.

RESUMO

BACKGROUND & OBJECTIVES: Structural interventions have the capacity to improve the outcomes of HIV/AIDS interventions by changing the social, economic, political or environmental factors that determine risk and vulnerability. Marginalized groups face disproportionate barriers to health, and sex workers are among those at highest risk of HIV in India. Evidence in India and globally has shown that sex workers face violence in many forms ranging from verbal, psychological and emotional abuse to economic extortion, physical and sexual violence and this is directly linked to lower levels of condom use and higher levels of sexually transmitted infections (STIs), the most critical determinants of HIV risk. We present here a case study of an intervention that mobilized sex workers to lead an HIV prevention response that addresses violence in their daily lives. METHODS: This study draws on ethnographic research and project monitoring data from a community-led structural intervention in Mysore, India, implemented by Ashodaya Samithi. Qualitative and quantitative data were used to characterize baseline conditions, community responses and subsequent outcomes related to violence. RESULTS: In 2004, the incidence of reported violence by sex workers was extremely high (> 8 incidents per sex worker, per year) but decreased by 84 per cent over 5 years. Violence by police and anti-social elements, initially most common, decreased substantially after a safe space was established for sex workers to meet and crisis management and advocacy were initiated with different stakeholders. Violence by clients, decreased after working with lodge owners to improve safety. However, initial increases in intimate partner violence were reported, and may be explained by two factors: (i) increased willingness to report such incidents; and (ii) increased violence as a reaction to sex workers' growing empowerment. Trafficking was addressed through the establishment of a self-regulatory board (SRB). The community's progressive response to violence was enabled by advancing community mobilization, ensuring community ownership of the intervention, and shifting structural vulnerabilities, whereby sex workers increasingly engaged key actors in support of a more enabling environment. INTERPRETATION & CONCLUSIONS: Ashodaya's community-led response to violence at multiple levels proved highly synergistic and effective in reducing structural violence.
