Abstract:
Objectives:To investigate the proportion of MSM among males over 15 years old and analyze its related factors to provide a reference for estimation of MSM size.Methods:Using cross-sectional survey design, multi-stage sampling method, and street interception survey method, a survey was conducted on males over 15 years old in Kunming from October to December 2019, with an estimated sample size of 9 908.Results:Totally, 10 707 males were recruited from 30 sites in 5 counties, and 10 283 were effectively surveyed with a response rate of 96.0%. Respondents aged 16 to 40 accounted for 75.3% (7 748), senior high school or above 71.1% (7 312), and unmarried 49.8% (5 121). The proportion of homosexual behavior in the past half-year was 1.06% (95% CI: 0.86%-1.26%), and the age-adjusted rate was 0.97% (95% CI: 0.78%-1.16%). And multivariate logistic regression showed the associated factors for homosexual behavior as following: proportion of main urban area was 2.217 times (95% CI:1.004-4.895) that of the outer suburbs, registered residence outside Kunming was 0.421 times (95% CI:0.260-0.682) that of in Kunming, having been in Kunming ≤6 months was 2.282 times (95% CI:1.262-4.126) that of >6 months, senior middle school or above was 0.336 times (95% CI:0.228-0.495) that of junior middle school and below, and being married was 0.462 times (95% CI:0.303-0.705) that of unmarried. Conclusions:The proportion of over 15-year-old males who have recently practiced male-male behavior was close to 1.00% in Kunming. The relevant factors included survey areas with a permanent residency of Kumming, short-time residency, education level, and marital status. This study obtained the data and related factors, which provided a reference for estimating MSM size in Yunnan province.
