摘　　要：目的分析重庆市≥50岁人群经商业异性性行为感染的人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染者/艾滋病(acquired immune deficiency syndrome,AIDS)患者(简称HIV/AIDS)特征及时空分布规律,为老年人群的AIDS防控提供科学参考。方法基于中国疾病预防控制信息系统中2015―2023年重庆市报告时年龄≥50岁、接触史为商业异性性行为的HIV/AIDS病例,采用SPSS 23.0软件进行描述性分析及趋势分析,采用ArcGIS 10.6软件进行空间分析。结果2015―2023年重庆市共报告≥50岁人群经商业异性性行为感染的HIV/AIDS病例16096例,占所有经商业异性性行为感染病例的72.3%,占比呈上升趋势(χ^(2)_(趋势)=631.208,P<0.001)。病例以男性(94.7%)、已婚(59.0%)、50~<70岁(68.9%)、农民/民工(62.1%)、小学及以下文化水平(71.1%)为主。病例主要分布在中心城区及主城新区(82.7%),医疗机构检测发现的病例占70.2%,首次CD4^(+)T淋巴细胞计数<350个/μL占68.8%。空间分析显示,重庆市≥50岁人群经商业异性性行为感染的HIV/AIDS病例呈聚集性分布,以永川区、大足区、荣昌区为中心向周边扩散。结论重庆市报告≥50岁人群经商业异性性行为感染的HIV/AIDS病例逐年增加,且存在聚集性,应开展综合性干预措施,以控制由商业异性性行为引起的HIV传播。Objective To analyze the characteristics and spatiotemporal distribution of human immunodeficiency virus(HIV)/acquired immune deficiency syndrome(AIDS)cases among individuals aged≥50 infected through commercial heterosexual behavior in Chongqing,and to provide scientific references for HIV/AIDS prevention and control among the elderly population.Methods The reported HIV/AIDS cases aged≥50 from 2015 to 2023 with a history of commercial heterosexual behavior were analyzed.SPSS 23.0 software was used for descriptive epidemiological,and ArcGIS 10.6 software was used for spatial analysis.Results From 2015 to 2023,Chongqing reported 16096 HIV/AIDS aged≥50 and infected through commercial heterosexual behavior,accounting for 72.3%of all HIV/AIDS infected through commercial heterosexual behavior,and the proportion showed an increasing trend(χ^(2)_(trend)=631.208,P<0.001).The cases were predominantly male(94.7%),married(59.0%),aged 50-<70 years(68.9%),farmers(62.1%),and with primary school education or below(71.1%).The majority of cases were distributed in the central urban areas and main urban districts(82.7%),primarily detected through medical institutions(70.2%),with 68.8%having initial CD4^(+)T cell counts<350 cells/μL.Spatial analysis indicated that the cases were clustered and centered around Yongchuan District,Dazu District and Rongchang District spreading to surrounding districts.Conclusions The proportion of HIV/AIDS cases aged≥50 infected though commercial heterosexual behavior in Chongqing has been increasing annually,and the distribution of cases is clustered.Comprehensive intervention measures should target commercial heterosexual behavior.
