To understand the commercial homosexual behavior characteristics of men who have sex with men (MSM) and the factors associated with unprotected anal intercourse (UAI) in this population, and provide reference for the development of intervention strategy in MSM. Men who were aged ≥16 years and had anal sex with men in the past 6 months were recruited through internet in Fuzhou from January to December 2023 for a cross-sectional study with a sample size of 283. Multivariate logistic regression model was used to analyze the factors associated with the incidence of UAI in the past 6 months in MSM. The SPSS 25.0 software was used for statistical analysis. In 4 484 MSM, the proportion of those with commercial homosexual behaviors was 9.59% (430/4 484), the average age was (27.00±9.07) years. In the MSM with commercial homosexual behaviors, 70.00% (301/430) had anal sex in the past one week, and 43.02% (185/430) had anal sex with more than 10 partners in the past 6 months. The proportion of MSM with UAI was 75.58% (325/430) in the past 6 months. The results of multivariate analysis showed showed that in MSM with commercial homosexual behaviors in the past 6 months, compared with those who were students, age >18 years at the first sexual intercourse, had not anal sex in the past one week, and anal sex with less than 10 partners in the past 6 months, the risk for UAI was higher in those who were not students (a=1.99,95%:1.18-3.36), those who were aged ≤18 years at first sexual intercourse sex (a=2.04,95%:1.26-3.29), those who had anal sex in the past one week (a=2.04,95%:1.25-3.33), and those who had anal sex with more than 10 partners in the past 6 months (a=1.97,95%:1.16-3.35). The risk for UAI was high in MSM with commercial homosexual behaviors in Fuzhou, so it is necessary to improve the awareness of safe sex and promote sex with regular partners and condom use, and preventing drug abuse in MSM.
了解男男性行为者（MSM）商业性行为特征及该人群中与无保护肛交（UAI）相关的因素，为制定MSM干预策略提供参考。2023年1月至12月，通过互联网在福州招募年龄≥16岁且在过去6个月内有过男男性行为的男性进行横断面研究，样本量为283例。采用多因素logistic回归模型分析MSM过去6个月UAI发生情况的相关因素。使用SPSS 25.0软件进行统计分析。在4484例MSM中，有商业性行为的比例为9.59%（430/4484），平均年龄为（27.00±9.07）岁。在有商业性行为的MSM中，70.00%（301/430）在过去一周内有过肛交，43.02%（185/430）在过去6个月内与10个以上性伴发生过肛交。过去6个月有UAI的MSM比例为75.58%（325/430）。多因素分析结果显示，在过去6个月有商业性行为的MSM中，与学生、首次性行为年龄>18岁、过去一周内无肛交、过去6个月内肛交性伴数<10个的MSM相比，非学生（a=1.99，95%CI：1.18-3.36）、首次性行为年龄≤18岁（a=2.04，95%CI：1.26-3.29）、过去一周内有过肛交（a=2.04，95%CI：1.25-3.33）、过去6个月内肛交性伴数>10个的MSM发生UAI的风险更高。福州市有商业性行为的MSM发生UAI的风险较高，需提高其安全性行为意识，倡导与固定性伴性行为并使用避孕套，预防MSM人群中的药物滥用。
