Abstract Objective To investigate the influencing factors for unprotected anal intercourse (UAI) among men who have sex with men (MSM), so as to provide the reference for formulating intervention strategies for high-risk behaviors among MSM. Methods The MSM who had engaged in anal intercourse with men in the past six months were recruited at a HIV testing site of the "Danlan Public Welfare" organization in Beijing Municipality using the convenient sampling method from March to May 2024. Demographic information, UAI in the past six months and the situation of receiving AIDS intervention were collected through questionnaire surveys. Factors affecting UAI were analyzed using a multivariable logistic regression model. Results A total of 322 MSM were surveyed, with an average age of (32.00±8.26) years. There were 271 MSM (84.16%) with an educational level of college or above, 171 MSM (53.11%) employed in enterprises, institutions, or government sectors. In terms of the relationship/marital status, 189 MSM were single (58.70%), 90 had same-sex partners (27.95%), and 43 had opposite-sex partners or were married (13.35%). In the past six months, 252 MSM had UAI (78.26%). Multivariable logistic regression analysis showed that the MSM with same-sex partners (OR=1.995, 95%CI: 1.014-3.927), with opposite-sex partners or who were married (OR=3.081, 95%CI: 1.087-8.731), and employed in physical labor (OR=2.954, 95%CI: 1.020-8.557) were more likely to have UAI. Conclusions The prevalence of UAI among MSM is relatively high. The main influencing factors are relationship/marital status and occupation. There is a need to strengthen the promotion and intervention of condom use.
