To understand the routes of newly reported HIV/AIDS cases with heterosexual mode of transmission in six districts of Chongqing city, and to provide evidence for HIV/AIDS prevention and control programs regarding heterosexual mode of transmission on HIV. HIV/AIDS cases that were newly reported as with heterosexual mode of transmission in six districts of Chongqing from July 1st to October 1st in 2019, were recruited in the study. Information related to their sociodemographic characteristics and heterosexual behaviors was collected. A self-designed questionnaire was used in this face-to-face survey. A total of 312 HIV/AIDS cases with heterosexual mode of transmission were recruited. Most of them were males (207, 66.3), aged 50 years or over (210, 67.3), having junior high school or lower education (252, 80.8), married or cohabitating (200, 64.1). 48.7 (152/312) of them were infected through commercial sexual contact while 40.4 (126/312) of them were infected by spouses or stabled partners. 10.9 (34/312) of them were infected by non-marital and non-commercial sexual contacts. Significant differences were noticed on the infection mode of heterosexual transmission in gender, age and occupation (<0.05). Results from the multivariate logistic regression analysis revealed that: male (=822.34, 95: 103.99-6 503.10), junior high school and lower education level (=3.02, 95: 1.05-8.66), household chores and underemployed (=0.23, 95: 0.07-0.76) were influencing factors on HIV infection that were through commercial sexual contacts. Male (=29.20, 95: 9.40-90.75), junior high school and lower education level (=4.28, 95: 1.24-14.81) were influencing factors on HIV infection, through non-marital and non-commercial sexual contacts. In addition to meeting sexual partners in offline places, some HIV/AIDS patients with heterosexual mode of transmission had developed sexual partnerships through online dating and with low-grade venue as the main place for sex engagement. Newly reported HIV/AIDS cases under heterosexual mode of transmission in Chongqing were mainly infected from offline low-grade venues, and caused by commercial sexual engagement. The routes of HIV infections that caused by heterosexual contact should be deeply understood in order to develop targeted intervention programs.
了解重庆市六个区新报告的经异性传播的艾滋病病毒/艾滋病（HIV/AIDS）病例的感染途径，为针对HIV异性传播途径的艾滋病防控项目提供依据。选取2019年7月1日至10月1日在重庆市六个区新报告的经异性传播的HIV/AIDS病例纳入研究。收集其社会人口学特征和异性性行为相关信息。本次面对面调查采用自行设计的问卷。共纳入312例经异性传播的HIV/AIDS病例。其中男性居多（207例，占66.3%），年龄50岁及以上者居多（210例，占67.3%），初中及以下文化程度者居多（252例，占80.8%），已婚或同居者居多（200例，占64.1%）。其中48.7%（152/312）通过商业性接触感染，40.4%（126/312）通过配偶或固定性伴感染。10.9%（34/312）通过非婚非商业性接触感染。异性传播的感染方式在性别、年龄和职业方面存在显著差异（P<0.05）。多因素logistic回归分析结果显示：男性（OR=822.34，95%CI：103.99-6503.10）、初中及以下文化程度（OR=3.02，95%CI：1.05-8.66）、家务及无业（OR=0.23，95%CI：0.07-0.76）是通过商业性接触感染HIV的影响因素。男性（OR=29.20，95%CI：9.40-90.75）、初中及以下文化程度（OR=4.28，95%CI：1.24-14.81）是通过非婚非商业性接触感染HIV的影响因素。部分经异性传播的HIV/AIDS患者除在线下场所结识性伴外，还通过网络交友发展性伴，且以低档场所为主要性接触地点。重庆市新报告的经异性传播的HIV/AIDS病例主要从线下低档场所感染，以商业性接触所致为主。应深入了解异性接触导致HIV感染的途径，制定针对性干预措施。
