To know the situation of extramarital sexual behaviors and HIV infection in middle-aged and elderly people in Chongqing, and provide reference for AIDS prevention and treatment. From October to December 2017, a multi-stage sampling method was used to recruit middleaged and elderly people aged ≥50 years who lived in Dazu and Hechuan districts of Chongqing for at least one year, with a sample size of 410. Face-to-face questionnaires survey and HIV antibody test were conducted. A total of 408 people were surveyed, including 313 males and 95 females aged 50-88 (64.93±9.03) years. The HIV infection rate was 1.47% (6/408), with the rate of 1.28% (4/313) in males and 2.11% (2/95) in females. The awareness rate of AIDS related knowledge was 37.50% (153/408). And 18.87% (77/408) of subjects surveyed reported extramarital sexual behaviors, 7.60% (31/408) reported extramarital sexual behaviors in the past half year, the constant condom use rate was 19.35% (6/31). The results of multivariate logistics model analysis on extramarital sexual behaviors showed that the prevalence in males were 39.51 times higher than that in females (=39.51, 95: 5.03-310.30), 4.60 times higher in those who were unmarried, divorced or widowed than that in the married or cohabitants (=4.60, 95: 1.50-14.05), 2.03 times higher in those with outside activities than those with individual activities (=2.03, 95: 1.08-3.81) and 3.94 times higher in those with self-evaluation of emptiness of living state than that in those with engaged life (=3.94, 95: 1.86-8.36). The prevalence of extramarital sexual behavior in middle-aged and elderly people in some counties and districts in Chongqing is high. The factors such as gender, marital status, leisure activities, and self-evaluation of living state were related to the prevalence of extramarital sexual behaviors in this population. The condom use rate in extramarital sexual behavior was low. It is necessary to take effective interventions in this population.
了解重庆市中老年人群婚外性行为及艾滋病病毒（HIV）感染情况，为艾滋病防治工作提供参考。2017年10月至12月，采用多阶段抽样方法，招募居住在重庆市大足区和合川区且居住时间至少1年的≥50岁中老年人群，样本量为410人。进行面对面问卷调查及HIV抗体检测。共调查408人，其中男性313人，女性95人，年龄50 - 88岁（64.93±9.03）。HIV感染率为1.47%（6/408），男性感染率为1.28%（4/313），女性感染率为2.11%（2/95）。艾滋病相关知识知晓率为37.50%（153/408）。18.87%（77/408）的被调查者报告有婚外性行为，7.60%（31/408）报告在过去半年有婚外性行为，安全套坚持使用率为19.35%（6/31）。婚外性行为的多因素logistic模型分析结果显示，男性婚外性行为患病率是女性的39.51倍（=39.51，95%CI：5.03 - 310.30），未婚、离异或丧偶者是已婚或同居者的4.60倍（=4.60，95%CI：1.50 - 14.05），有外出活动者是个体活动者的2.03倍（=2.03，95%CI：1.08 - 3.81），自我评估生活状态空虚者是生活充实者的3.94倍（=3.94，95%CI：1.86 - 8.36）。重庆市部分区县中老年人群婚外性行为患病率较高。性别、婚姻状况、休闲活动及生活状态自我评估等因素与该人群婚外性行为患病率有关。婚外性行为中安全套使用率较低。有必要对该人群采取有效干预措施。
