Hiv Transmission Risk

In this study, we assessed if the superimposition of incident sexually transmitted infections (STIs) on HIV phylogenetic analyses could reveal possible sexual behaviour misclassifications in our HIV-infected population. HIV-1 sequences collected between 1997 and 2014 from 1169 individuals attending a HIV clinic in Antwerp, Belgium were analysed to infer a partial HIV transmission network. Individual demographic, clinical and laboratory data collected during routine HIV follow-up were used to compare clustered and non-clustered individuals using logistic regression analyses. In total, 438 (37.5%) individuals were identified in 136 clusters, including 76 transmission pairs and 60 clusters consisting of three or more individuals. Individuals in a cluster were more likely to have a history of syphilis, Chlamydia and/or gonorrhoea (P < 0.05); however, when analyses were stratified by HIV transmission risk groups (heterosexual and men who have sex with men [MSM]), this association only remained significant for heterosexuals with syphilis (P = 0.001). Under closer scrutiny, this association was driven by six heterosexual men who were located in six almost exclusively MSM clusters. A parsimonious conclusion is that these six individuals were potentially misclassified as heterosexual. Improving the accuracy of sexual behaviour reporting could improve care.

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.

Hiv Transmission Risk

In recent years, prevalence of Human Immunodeficiency Virus (HIV) has increased substantially in Bali, Indonesia, in men who have sex with men (MSM) and transgender women, known locally as ‘waria’. There are limited behavioural data in this population. We conducted a behavioural survey of MSM/waria in Bali in March–April 2018. Respondents were primarily recruited by HIV outreach workers. Respondents reported details about anal intercourse events with their last male/waria romantic partner and/or last male/waria casual partner (respondents could report on both if relevant). Statistical significance was tested with generalised estimating equations. Among 709 participants, median age was 27 (interquartile range = 24–31), and 92.1% were male and 7.9% were waria. One-third were born in Bali. Overall, 85.9% had ever had an HIV test; 55.1% reported being HIV-negative, 15.0% HIV-positive, and 30.0% had unknown serostatus. Most (86.5%) reported sex with men, 9.5% with waria, and 20.0% with women in the previous 6 months. Respondents described 703 anal intercourse events (397/306 with romantic/casual partners, respectively; 191 reported on both). Over half (56.5%) of the events were protected by condoms and 7.3% by biomedical prevention (2.6% by PrEP in either partner, 4.7% by HIV treatments in either partner). Thus, 36.3% of events involved unprotected condomless anal intercourse (40.8%/30.4% in romantic/casual partners, respectively). In multivariate analysis, unprotected condomless anal intercourse events were associated with romantic partners (p < 0.001), being born in Bali (p = 0.002), lower education (p = 0.013), believing that withdrawal before ejaculation is effective (p < 0.001), liking to use withdrawal (p = 0.021), and not liking condoms (p < 0.001). One-quarter of events had potentially reduced HIV transmission risk through non-condom-based risk reduction strategies, while 11.1% had no potential risk reduction. Events presenting the highest potential risk of HIV transmission were more commonly reported by respondents born in Bali.
