  Objective  This study aimed to explore the prevalence of associated with rectal douching among men who have sex with men (MSM) and related factors, in order to provide targeted interventions.  Methods  In this observational study, snowball sampling was used to recruit 400 MSM in KTV, bathroom, bar and so on in Wuxi, Jiangsu Province from May 1, 2020 to July 10, 2020. A questionnaire was used to collect socio-demographic characteristics, behaviors, substances abuse, history of diagnosed sexually transmitted diseases (STDs) and rectal douching. Blood sample was collected and tested for HIV. Chi-square test and Logistic regression analysis model were performed to determine factors associated with rectal douching among MSM.  Results  A total of 400 MSM were recruited, among whom 51.3% practiced rectal douching in the past 6 months, 57.6% before anal sex only, 14.6% after anal sex only and 27.8% (57/205) before and after anal sex. Monthly income > 5 000 RMB (OR=2.18, 95% CI: 1.36-3.51, P=0.001), homosexual (OR=19.35, 95% CI: 4.01-93.38, P < 0.001), bisexual (OR=10.31, 95% CI: 2.12-50.14, P=0.004), engaging in receptive anal sex exclusively in the past 6 months (OR=8.96, 95% CI: 4.14-19.40, P < 0.001), engaging in both insertive and receptive anal sex in the past 6 months (OR=10.71, 95% CI: 4.80-23.89, P < 0.001), substances use (OR=3.20, 95% CI: 1.60-6.42, P=0.001), history of diagnosed STDs (OR=2.17, 95% CI: 1.30-3.63, P=0.003) and positive HIV status (OR=3.60, 95% CI: 1.14-11.36, P=0.029) were associated with rectal douching in MSM.  Conclusions  Rectal douching is common in MSM, which is a significant factor associated with HIV transmission. Health education and behavioral interventions related to rectal douching should be enhanced among MSM in order to reduce the risk of HIV transmission.
