Analysis of awareness of HIV/AIDS-related knowledge and related behavior among men who have sex with men (MSM) in Changsha

  Objective  To understand the awareness of HIV/AIDS-related knowledge and characteristics of sexual behaviors among men who have sex with men (MSM) in Changsha City.  Methods  By a snowball sampling method, volunteers were recruited in two social public welfare organizations in Changsha (Qingcai and Zhongda Sunshine) and interviewed by anonymous electronic questionnaires. Data were analyzed using software SPSS 19.0.  Results  Among 150 MSM, the overall awareness rate of HIV/AIDS-related knowledge was 86.0% (129/150). For different demographic characteristics, higher age group, higher education level and higher income groups had significantly higher rates of awareness about HIV/AIDS related knowledge, compared with the reference groups, respectively. For the sexual behaviors, 32.7% of the investigated MSM population had their first MSM sexual intercourse at age of <18 years old, the rate of ≥ 18 years old group was significantly higher than the <18 years old group (χ2=4.315, P=0.038), 46.7% of the MSM population had more than 1 sexual partner during the past six months, the ratio of MSM used condoms in the sexual intercourse occasionally or never was 29.3% and 6.7%, respectively.  Conclusions  Young age, relatively low educational level and low income MSM in Changsha had a relative low awareness of HIV/AIDS-related knowledge. MSM in Changsha City had first MSM sexual intercourse at a very younger age. There is an urgent need to take well-targeted measures to improve the HIV/AIDS-related knowledge with special MSM population, and develop effective intervention measures for the high-risk sexual behaviors among MSM.
