Hiv Transmission Risk

ObjectiveThe HIV epidemic in China is shifting from the high-risk groups of men who have sex with men (MSM), injection drug users and sex workers to the general population, and sexual contact among spouses is assumed to be one route of transmission. Our objective was to determine the intention to marry and the expected extramarital male-to-male sex among single Chinese MSM, in order to estimate the potential HIV transmission risk among MSM living with HIV and their female spouses.MethodsWe conducted a web-based, cross-sectional survey between May 2016 and May 2017. A questionnaire covering sociodemographic characteristics, sexual behaviours, HIV-related and homosexuality-related stigma, marriage intention, and expected extramarital sexual behaviours was completed by 556 single MSM in Hunan, China. Descriptive statistics, χ2 test, two-sample t-test and multivariate logistic regression analysis were performed.ResultsCurrently 48.9% of the participants intended to marry a woman in their lifetime, and 91% of them reported that they would continue to have sex with men after getting married. Those who were living with parents (OR=2.26), self-identified as bisexual (OR=2.57), had at least one heterosexual partner in the previous 6 months (OR=0.33) and perceived a higher level of self-homosexual stigma (OR=1.78) had greater intention to marry a woman.ConclusionNearly half of Chinese MSM intend to marry women, which has significantly dropped from the estimated percentage more than 10 years ago for Chinese MSM. However, the expectation of extramarital homosexual behaviours was common in these men. Sexual and gender minority stresses especially from family members, homosexual identity assertiveness and related stigma were the main factors for marriage intention, which should be addressed in future studies and practices.

Exposure Prophylaxis

Oral Pre-Exposure Prophylaxis (PrEP) is highly effective in lowering HIV transmission risk. The Bill and Melinda Gates-funded Jilinde Project was designed to identify the best ways to introduce and support PrEP services in Kenya for female sex workers, men who have sex with men, and adolescent girls and young women. We chose Developmental Evaluation (DE) as a core project approach because our goal was not just to recruit 20,000 new PrEP users, but to learn how to deliver PrEP effectively to optimally benefit users in a complex, dynamic, resource-limited setting. This paper describes how we incorporated DE into the Jilinde Project, and shares experiences and lessons learned about the value of DE in PrEP service implementation in a real-world situation. With the Ministry of Health, Jilinde developed consensus about the structure and roll-out of PrEP services. The DE evaluator, embedded in Jilinde, designed and implemented the five-step DE methodology—collect, review, reflect, record and act—according to a core set of project guiding principles. The paper describes how we operationalized the five elements, citing findings reported and actions taken reflecting on the data. It summarizes challenges to DE implementation, such as uneven uptake and competing demands, and how we addressed those challenges. Used consistently, DE helped adapt and refine PrEP services, improve service access, reach target audiences and improve continuation rates. The look, feel and yield of our DE efforts evolved over time, increasingly integrated into existing systems and providing deeper and richer understandings, and we learned how to better implement DE in the future. This case study provides practical guidance for using a DE approach in program design. The DE process can be used successfully working with partners on a common complex public health challenge within a dynamic environment in a way that feeds back into and improves programs.

Abstract Background Male sex workers are at high-risk for acquisition of sexually transmitted infections (STIs), including human immunodeficiency virus (HIV). We quantified incidence rates of STIs and identified their time-varying predictors among male sex workers in Mexico City. Methods From January 2012 to May 2014, male sex workers recruited from the largest HIV clinic and community sites in Mexico City were tested for chlamydia, gonorrhea, syphilis, hepatitis, and HIV at baseline, 6-months, and 12-months. Incidence rates with 95% bootstrapped confidence limits were calculated. We examined potential time-varying predictors using generalized estimating equations for a population averaged model. Results Among 227 male sex workers, median age was 24 and baseline HIV prevalence was 32%. Incidence rates (per 100 person-years) were as follows: HIV [5.23; 95% confidence interval (CI): 2.15–10.31], chlamydia (5.15; 95% CI: 2.58–9.34), gonorrhea (3.93; 95% CI: 1.88–7.83), syphilis (13.04; 95% CI: 8.24–19.94), hepatitis B (2.11; 95% CI: 0.53–4.89), hepatitis C (0.95; 95% CI: 0.00–3.16), any STI except HIV (30.99; 95% CI: 21.73–40.26), and any STI including HIV (50.08; 95% CI: 37.60–62.55). In the multivariable-adjusted model, incident STI (excluding HIV) were lower among those who reported consistently using condoms during anal and vaginal intercourse (odds ratio = 0.03, 95% CI: 0.00–0.68) compared to those who reported inconsistently using condoms during anal and vaginal intercourse. Conclusions Incidence of STIs is high among male sex workers in Mexico City. Consistent condom use is an important protective factor for STIs, and should be an important component of interventions to prevent incident infections.
