HIV related behaviours and attitudes among Chinese men who have sex with men in Hong Kong: a population based study

Objective: This study was conducted in order to determine the prevalence of men having sex with men (MSM) and their HIV related behaviours and attitudes among Chinese men in Hong Kong. Methods: A large scale, random, population based, anonymous telephone survey of 14 963 men between the ages of 18 - 60 was conducted. The overall response rate was approximately 57%. Results: Of the respondents, 4.6% had ever engaged in MSM activity. In the 6 months preceding the survey, 2.0% had engaged in MSM behaviours ( active MSM) and 0.5% reported having engaged in anal sex MSM behaviours. Among anal sex MSM, consistent condom use was 42.9% with male noncommercial sex partners and even lower with male commercial sex partners (35.7%). Approximately 11% of anal sex MSM and 4.1% of the non-anal sex MSM had contracted an STD in the last 6 months. The prevalence of HIV testing was only 20.6% among anal sex MSM and 11.9% among non-anal sex MSM. Conclusions: Active MSM in Hong Kong are at high risk of HIV infection. The belief of low vulnerability to HIV is prevalent among active MSM in Hong Kong with only 2.0% believing that their chances of HIV infection as being "very likely.''
