- Abstract: Objective:To analyze high-risk behaviors related to HIV infection in men who have sex with men (MSM) recruited by different methods in Zhenjiang city, and to provide a reference for precise prevention and control of acquired immunodeficiency syndrome (AIDS) .Methods:From April to June in 2020, MSM in Zhenjiang city were recruited as research subjects through the center for disease control and prevention (CDC) voluntary counseling and testing (VCT) clinic and community-based organizations (CBOs) . Information such as demographic characteristics, drug abuse, HIV testing history and high-risk sexual behavior were collected through a unified questionnaire survey. Chi-square test or Fisher′s exact test was used to analyze differences in relevant characteristics of MSM recruited by different methods.Results:A total of 641 MSM were recruited by the two methods, including 442 (68.95%) recruited from CBOs and 199 (31.05%) from CDC; the proportion of MSM aged under 20 years was significantly higher in the CBO group (6.56%) than in the CDC group (1.01%, χ2 = 9.20, P = 0.002) ; the proportions of MSM receiving health education information on potential hazards of drug use from professional health institutions and new network media were significantly higher in the CDC group (7.54% [15/199], 16.58% [33/199], respectively) than in the CBO group (3.39% [15/442], χ2 = 5.28, P = 0.022; 9.50% [42/442], χ2 = 6.66, P = 0.010) . In terms of characteristics of sexual behavior, the CBO group showed significantly increased proportions of individuals having group sex (25.21%, 30 cases) and those having unprotected sexual intercourse with women (47.51%, 210 cases) compared with the CDC group (7.50% [6 cases], χ2 = 10.13, P = 0.001; 27.64% [55 cases], χ2 = 22.35, P < 0.001, respectively) , but significantly decreased proportions of heterosexuals (2.04%, 9 cases) , individuals unknowing about the HIV status of sexual partners (22.40%, 99 cases) and those having unprotected anal sex with men (39.82%, 176 cases) compared with the CDC group (6.53% [13 cases], χ2 = 8.37, P = 0.004; 39.70% [79 cases], χ2 = 20.48, P < 0.001; 57.29% [114 cases], χ2 = 16.90, P < 0.001, respectively) . Compared with the CDC group, the CBO group showed significantly decreased proportions of individuals ever having an HIV test (74.43% [329 cases] vs. 80.90% [161 cases], χ2 = 3.19, P = 0.074) and those getting the latest HIV test from CDC (23.10% [76 cases] vs. 57.14% [92 cases], χ2 = 99.41, P < 0.001) , as well as decreased prevalence of HIV infection (5.20% [23 cases] vs. 13.07% [26 cases], χ2 = 21.85, P < 0.001) . Conclusions:The MSM recruited from CBO and CDC are complementary in terms of demographics and behaviors, and can represent the general MSM population. Specific prevention and control measures for AIDS should be taken according to different characteristics of the MSM population.
