摘　　要：目的 分析四川省经异性性传播艾滋病疫情时空分布特征,为分类指导艾滋病经异性性传播疫情防控提供参考依据。方法 以县域内异性性传播感染HIV/AIDS现存活病例数占15岁以上人口比例为时空聚集性分析指标,利用ArcGIS Pro 2.7对2008-2021年四川省经异性性传播艾滋病疫情进行新兴时空热点分析,以P<0.05为差异有统计学意义。结果 2008-2021年四川省经异性性传播艾滋病疫情经新兴时空热点分析方法共检测出5类47个时空热点和5类51个时空冷点,时空热点主要分布于四川省中部和南部地区,时空冷点主要分布于四川省北部地区。其中,连续热点主要分布于成都市内与中心城区相邻的县区、宜宾市和自贡市的大部分县区、内江市和泸州市的全部县区、以及眉山市、雅安市、甘孜州的交界县域;历史热点均位于攀枝花市;新增热点、散发热点和增强热点分布于川南市州的交界县域;振荡冷点均位于达州市。结论 四川省经异性性传播艾滋病疫情的时空分布具有地区差异性,成都市和川南4市的连续热点县区和增强热点县区是经异性性传播艾滋病疫情高流行地区中的重点防控地区,需在该地区持续加大商业性行为干预,老年男性群体仍是重点干预对象,同时需警惕疫情由连续热点向相邻的非热点县区扩散。Objective To analyze the spatial-temporal distribution characteristics of HIV/AIDS infected by heterosexual transmission in Sichuan province,to provide reference for classifying and guiding the prevention and control of HIV/AIDS infected by heterosexual transmission.Methods The proportion of living HIV/AIDS cases infected by heterosexual transmission in the population over 15 years old at the county level was taken as the spatial-temporal aggregation analysis index,ArcGIS Pro 2.7 software was used for Emerging Hot Spot Analysis,the difference P<0.05 was considered to be statistically significant.Results The Emerging Hot Spot Analysis method had detected 47 spatiotemporal hot spots in 5 categories and 51 spatiotemporal cold spots in 5 categories.The spatiotemporal hot spots were mainly distributed in the central and southern regions of Sichuan province,and the spatiotemporal cold spots were mainly distributed in the northern regions of Sichuan province.Consecutive Hot Spots were mainly distributed in the counties adjacent to the central urban area of Chengdu,most of the counties of Yibin and Zigong,all of the counties of Neijiang and Luzhou,and the border counties of Meishan,Ya'an and Ganzi;Historical Hot Spots were all located in Panzhihua;New Hot Spots,Sporadic Hot Spots and Intensifying Hot Spots were distributed in the border counties of southern Sichuan;Oscillating Cold Spots were all located in Dazhou City.Conclusions The spatial-temporal distribution of HIV/AIDS infected by heterosexual transmission in Sichuan province has regional differences,the Consecutive Hot Spots an1dthe Intensifying Hot Spots in Chengdu and the four cities of southern Sichuan are the key areas for prevention and control in the high prevalence areass of HIV/AIDS infected by heterosexual transmission.It is necessary to continue to strengthen the commercial sexual behavior intervention in these areas.The elderly male population is still the key intervention population.At the same time,it is necessary to be alert to the spread of the epi
