SUMMARYThe impact of hepatitis B vaccination in men having sex with men in Amsterdam has been marginal until now, possibly because of increases in sexual risk behaviour counterbalancing the effect of vaccination. A mathematical model is used to describe the hepatitis B epidemic. The model shows that, with the current vaccination coverage, the decrease in incidence is small in the beginning. However, the number of infections prevented per vaccine administered rises over time. Nevertheless, increased risk behaviour reduces the benefit of vaccination. Targeting high-risk men is more successful in reducing and containing the epidemic than targeting low-risk men. In conclusion, the vaccination campaign is effective and should be intensified. High-risk men should be targeted for vaccination and for risk reduction.

Introduction: The rapid socio-economic development in Bhutan has brought changes in individual lifestyles resulting in increased risk behavior of the urban population, particularly the Drayang girls. This study investigated the underlying factors influencing the sexual risk behaviour of Drayang girls and their vulnerability to HIV and Sexually Transmitted Infection (STI). The Drayangs are dance bars in Bhutan where the women perform Bhutanese songs/dances on the stage to entertain the bar patrons and making them pay for their performance. Methods: This is a cross-sectional descriptive study conducted from May-July 2015 in three urban districts (Thimphu, Paro, and Phuentsholing) of Bhutan. The convenient non-random sampling method was used to recruit the respondents. We have collected the data using structured questionnaires including the taking of blood samples for HIV, Hepatitis B, and Syphilis testing. Results: Of the 245 Drayang girls recruited for this study, 28.2% have engaged in transactional sex and 71.8% in non-transactional sex within last month. Condom use during transactional sex was 36.2% and non-transactional sex was 21.6%. The prevalence of HIV was 0.82%, hepatitis B 6.9%, and syphilis 2.8%. The factors such as marital status (divorced and unmarried), living arrangements, current living cities, and alcohol consumption were significantly (p<0.05) associated with transactional sex among Drayang girls. Conclusion: Although the prevalence of HIV and STIs is low among the Drayang girls, the presence of high riskbehavior with low condom use still makes them vulnerable to HIV and STIs. The study recommends putting more effort in prevention of HIV and STI by increasing awareness of HIV and STI, targeted interventions like Behaviour Change Communications (BCC), condom promotion, condom negotiation skills and access for testing and treatment of HIV and STI.

AbstractIn a sample of men who have sex with men (MSM) (N = 3436) in Spain who bear intrinsic HIV risk, we investigated how internalised homonegativity (IH) is associated with the number of non-steady male partners with condomless intercourse (as a proxy of sexual risk behaviour). Using structural equation modelling (SEM), we examined the relationship between IH and sexual risk behaviour, and mediating effects of HIV/PrEP knowledge and substance use during sex on this relationship. We found no direct association between IH and sexual risk behaviour, nor did IH influence substance use during sex. In line with our hypothesis, association between IH and sexual risk behaviour was significant when mediated by HIV/PrEP knowledge. We found that as IH increased, sexual risk behaviour decreased, because higher IH was associated with lower HIV/PrEP knowledge while higher HIV/PrEP knowledge was associated with increased non-condom use with non-steady partners. Substance use during sex was significantly associated with sexual risk behaviour. Our results emphasize the continuing importance of prevention strategies focused on behavioural changes and community level interventions, especially targeting substance use.

<p class="abstract"><strong>Background:</strong> In India the estimated men who have sex with men (MSM) population is around 352, 000, among that 4.3% are living with HIV. The incidence of sexually transmitted infections (STIs) in MSM is greater than that reported in women and men who have sex with women only. The aim of the study is to determine the trends of sexual behaviour and the pattern of sexually transmitted infections in men who have sex with men.</p><p class="abstract"><strong>Methods:</strong> A retrospective study of the data collected from the clinical records of all MSM, who had attended the STI clinic of Kilpauk Medical College, Chennai, Tamil Nadu, during the three-year study period, from July 2016 to June 2019. Demographic data, sexual risk behaviour, condom usage and STIs, among the MSM, were computed and analyzed.<strong></strong></p><p class="abstract"><strong>Results:</strong> During the study period 489 MSM attended the STI clinic, 51.9% were bisexual and 48.1 % were homosexual. Among them, exclusive penetrative sex in 50.7%, exclusive receptive sex in 15.7% and both in 33.6% were reported. Condom usage was consistent in 18.8%, inconsistent in 28.8% and 52.9% never used condom. Unprotected sex is more common in oral sex than with anal sex. STIs were seen in 20.9% and HIV in 1.4% of MSM. Syphilis was the most common STI seen.</p><p class="abstract"><strong>Conclusions:</strong> Our study elucidated the high prevalence of STIs among MSM and increasing trends of sexual risk behaviour. Health service providers must take necessary steps to improve the provision of biological and medical measures to screen, treat and prevent infections.</p><p class="abstract"> </p>

Blood borne virus (BBV) infection in adults involved in high risk behaviour is well recognized. There are limited reported data on young people involved in high risk behaviour. A descriptive questionnaire was used to ascertain risk behaviour at the Young People’s Substance Misuse Service (Birmingham). Data collection included risk behaviour and serological tests for hepatitis B, C and HIV. Sixty-five of one-hundred three (63%) young people participated; 37/65 male; age range 13.9–18.9 (median 17.4 years). Risk behaviour included 6 intravenous drug, 58 cannabis, and 61 had sexual partners, of whom 52 (85%) engaged in unprotected sex. Sixty-five participants were negative for BBV infection: 9 were HBV immune. HB vaccination was not available at the centre (for <18 year), and all refused referral to their general practitioner for vaccination due to fear of disclosure. The main risk for BBV acquisition was unprotected sex with multiple sexual partners and illicit drug use. Most were unaware of the risks related to high risk behaviour. Effective education programmes of relevant risk factors with HBV vaccination should be implemented during preadolescence. We recommend an integrated service via specialized centres, to work together to improve awareness and increase efforts to vaccinate adolescents at risk for HBV infection.
