An analysis of HIV infection and the influencing factors among MSM in Baotou

Objective To understand human immunodeficiency virus（HIV） infection and the influencing factors among men who have sex with men（MSM）, and provide information for developing future prevention and control strategy. Methods Data of acquired immunodeficieny syndrome（AIDS） sentinel surveillance to MSM in Baotou from 2011 to 2012 were analyzed with SPSS 17.0 software. Results Four hundred and two MSM were surveyed in 2011, of whom 18 were HIV positive with an infection rate of 4.5% ; 409 MSM were surveyed in 2012, of whom 24 were HIV positive, with an infection rate of 5.9% ; the average infection rate was 5.2% in the two years. Single factor analysis showed that ethnic, educational background, condom use in the last homosexual intercourse and the venereal illness were the four influencing factors associated with HIV infection among MSM. Multivariate logistic regression analysis showed that educational background was positively correlated with HIV infection and the infection rate was higher among MSM with education above college than among those with education below college. Venereal illness increased the opportunity for HIV infection, and condom use during the last homosexual anal intercourse could reduce the opportunity for HIV infection. Conclusion AIDS prevention and control among MSM in Baotou has entered a critical stage. To strengthen publicity and education targeting the highly educated MSM, raise their risk prevention awareness, promote condom use and provide convenient and standardized sexually transmitted diseases clinic services will be helpful to reduce the possibility of HIV infection.
