Abstract:Objective To investigate the duration of homosexuality among the men who have sex with men (MSM), and to analyze the social and sexual behavior characteristics. Methods The snowball sampling method was used to recruit MSM in Mianyang City, Sichuan Province from March to October in 2015, and then anonymous surveys and serological testing were performed. Results A total of 1,202 cases were investigated. The median duration of homosexuality was 5 years. The MSM with homosexuality duration≤ 1 year, >1-5 years and >5 years accounted for 10.1%, 45.1% and 44.8% respectively. Their HIV infection rates were respectively 6.6%, 4.6% and 7.1%. Their accumulated syphilis infection rates were respectively 3.6%, 5.3% and 20.4%. Their rates of accepting the publicity and distribution of condom/AIDS counseling and testing were 67.7%, 86.7% and 91.4%. Their rates of receiving peer education were respectively 70.8%, 83.0% and 87.5%. Their rates of protective anal sex in recent 6 months were respectively 76.2%, 86.7% and 81.7%. Their rates of economic pressure were 31.5%, 42.4% and 26.1%. Their rates of pressure from adaptability were respectively 13.7%, 8.1% and 4.6%. Their rates of family pressure were respectively 20.5%, 30.5% and 40.5%. Statistically significant differences were found in the above-mentioned rates (all P<0.05) except the infection rates of HIV (P=0.222). With the increase of duration of homosexuality, the number of friends of MSM known in the local area, the number of MSM with anal sex in recent 6 months and the age of the first homosexuality showed upward trends (all P<0.05). Conclusions MSM with different duration of homosexuality have different social and sexual behavior characteristics and different risk profiles of HIV infection.
