Dataset Information

HIV incidence among men who have sex with men in Beijing: a prospective cohort study.

ABSTRACT:

Objectives

(1) To assess the HIV incidence rate among men who have sex with men (MSM) in a large cohort study in Beijing, China and (2) to identify sociodemographic and behavioural risk factors of HIV seroconversion among MSM in Beijing, China.

Design

A prospective cohort study.

Setting

Baseline and follow-up visits were conducted among MSM in Beijing, China.

Participants

A cohort of 797 HIV-seronegative MSM was recruited from August to December 2009, with follow-up occurring after 6 and 12 months.

Primary and secondary outcome measures

At baseline and follow-up visits, participants reported sociodemographic and sexual behaviour information, and were tested for HIV, herpes simplex virus-2 (HSV-2) and syphilis with whole blood specimens. Cox regression analysis was used to identify factors associated with HIV seroconversion.

Results

Most study participants (86.8%) were retained by the 12-month follow-up. The HIV, HSV-2 and syphilis incidence rates were 8.09 (95% CI 6.92 to 9.26), 5.92 (95% CI 5.44 to 6.40) and 8.06 (95% CI 7.56 to 8.56) cases per 100 person-years, respectively. HIV seroconversion was significantly associated with being <25 years old, having <12 years of education, having >1 male sex partner in the past 6 months, and being syphilis positive or HSV-2 positive.

Conclusions

The HIV incidence among MSM in Beijing is serious. Interventions and treatment of sexually transmitted diseases (STD) should be combined with HIV control and prevention measures among MSM.

Project description:Although the HIV epidemic is generalized in West Africa, some population groups such as men who have sex with men (MSM), especially those engaged in transactional sex (TS), are thought to be particularly more vulnerable to HIV than others. However, few data are available to help identify their health-related needs with a view to implementing targeted prevention interventions. To fill this knowledge gap, we aimed to characterize MSM reporting TS (MSM-TS) and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM, which was conducted in Burkina Faso, Côte d'Ivoire, Mali and Togo. Three stigmatization sub-scores were constructed (experienced, perceived and internalized). The generalized estimating equation method was used for data analysis. Of the total 630 HIV-negative MSM recruited in CohMSM, 463, 410 and 244 had a follow-up visit at 6, 12 and 18 months, respectively. In a total of 1747 follow-up visits, 478 TS encounters were reported by 289 MSM-TS (45.9%). Of the latter, 91 regularly reported TS (31.5%), 55 (19.0%) stopped reporting TS after baseline, and 53 (18.3%) reported TS after baseline and 90 (31.1%) occasionally reported TS. The following variables, regarding the previous 6 months, were positively associated with TS: being younger (aOR[95%CI]:1.86[1.39-2.50]), less educated (aOR[95%CI]:1.49[1.09-2.03]), unmarried status (aOR[95%CI]:1.79[1.10-2.93]), satisfaction with current sex life (aOR[95%CI]:1.41[1.06-1.88]), group sex with men (aOR[95%CI]:2.07[1.46-2.94]), multiple male sexual partners (aOR[95%CI]:1.85[1.40-2.44]), receptive or versatile anal sex with male partners (aOR [95%CI]:1.48[1.12-1.96]), giving benefits in exchange for sex with a man (aOR[95%CI]:2.80[1.97-3.98]), alcohol consumption (aOR[95%CI]:1.44[1.08-1.93]) and drug use (aOR[95%CI]:1.82[1.24-2.68]) during sex, and finally experiencing stigmatization (aOR [95%CI]:1.15[1.07-1.25]). Condom use during anal sex (aOR[95%CI]:0.73[0.53-0.99]) was negatively associated with TS.
