      目的 调查昆明市>15岁男性发生男男性行为的比例及其相关因素,为MSM规模估计提供参考依据。方法 采用横断面调查设计、多阶段抽样方法和街头拦截调查方法,2019年10-12月对昆明市>15岁男性进行调查,估计样本量为9 908人。结果 在昆明市5个县区的30个招募点,共招募了>15岁男性10 707人,调查10 283人,应答率96.0%。调查对象16~40岁占75.3%(7 748人),高中及以上文化程度占71.1%(7 312人),未婚占49.8%(5 121人)。调查对象与年龄标准化后的最近半年发生男男性行为的比例分别为1.06%(95%CI:0.86%~1.26%)与0.97%(95%CI:0.78%~1.16%),多因素logistic回归分析结果显示,其相关因素包括调查区域在主城区是远郊县(区)的2.217倍(95%CI:1.004~4.895)、其他城市户籍地是昆明市户籍的0.421倍(95%CI:0.260~0.682)、在昆明市居住时间≤ 6个月是>6个月的2.282倍(95%CI:1.262~4.126)、高中及以上文化程度是初中及以下的0.336倍(95%CI:0.228~0.495)、已婚者是未婚者的0.462倍(95%CI:0.303~0.705)。结论 昆明市>15岁男性最近半年发生男男性行为比例接近1.00%,主要相关因素包括来自昆明市主城区、昆明市户籍、昆明市居住时间较短、初中及以下文化程度者和未婚者。本研究结果为云南省开展MSM规模估计提供了参考依据。
英文摘要:
      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.
