摘要
目的分析宝鸡市男男同性性行为人群(men who have sex with men, MSM)人类免疫缺陷病毒(human immunodeficiency virus, HIV)感染者/艾滋病(acquired immune deficiency syndrome, AIDS)患者人口学及时空分布特征,为实施"一地一策"精准防控策略提供理论依据。方法收集中国疾病预防控制信息系统中2008—2019年宝鸡市MSM中的HIV感染者/AIDS患者信息,采用描述性流行病学方法分析其人口学特征和发病情况,采用ArcGIS 10.1软件进行空间自相关及热点分析,应用SaTScan 9.0软件进行时空扫描分析。结果 2008—2019年宝鸡市共报告663例MSM HIV感染者/AIDS患者,年平均报告发病率为2.85/10万。全局自相关分析发现,2017—2019年HIV/AIDS发病存在空间聚集性(Moran′s I=0.53,Z=3.207,P=0.001)。"热点"分析发现宝鸡市高值聚集区位于金台区、陈仓区。时空扫描分析探测到2个高发聚集区,高发聚集区1位于渭滨区、金台区、凤翔县、陇县和千阳县(RR=3.75,LLR=131.088,P<0.001),时间跨度为2015—2019年。高发聚集区2主要分布于2019年的陈仓区、岐山县、扶风县、眉县(RR=1.93,LLR=8.193,P=0.031)。结论宝鸡市MSM中HIV感染者/AIDS患者发病数的时空变化逐渐出现规律性,时空聚集性显著增强,今后控制艾滋病疫情时应充分考虑MSM中HIV感染者/AIDS患者的"热点"区域及高发聚集区的时空聚集性信息。
Objective To study the temporal and spatial epidemiological characteristics of HIV/AIDS(human immunodeficiency virus/acquired immune deficiency syndrome) among men who have sex with men(MSM) epidemic reports in Baoji city of China. Methods Based on the database from National Information System for Comprehensive HIV/AIDS Prevention and Control, the incidence data of HIV/AIDS among MSM in Baoji from 2008 to 2019, spatial auto-correlation and hotspot analyses were performed using ArcGIS10.1 software.SaTScan9.0 software was used for spatio-temporal scanning analysis. Results A total of 663 MSM HIV/AIDS cases were reported during 2008—2019 with an annual incidence of 2.85/100 000.Global spatial autocorrelation analysis revealed a positive spatial autocorrelation during 2017—2019(Moran′s I=0.53, Z=3.207, P=0.001).The hotspots analysis showed that high-value clustering areas were Jintai, Chencang counties.Spatio-temporal scan analysis detected two high-incidence clusters.The main high-value clustering areas were Weibin, Jintai, Fengxiang, Longxian and Qianyang counties during 2015—2019(RR=3.75, LLR=131.088, P<0.001).The covered counties in secondary clusters appeared in Chencang, Qishan, Fufeng and Meixian counties(RR=1.93, LLR=8.193, P=0.031). Conclusions In recent years, the spatiotemporal changes of HIV-infected/AIDS patients among MSM have gradually appeared regularity,and the spatiotemporal aggregation has increased significantly in Baoji city.When controlling the AIDS epidemic in the future,full consideration should be given to the spatiotemporal aggregation information such as"hot spots"and the main high-value clustering areas of HIV-infected/AIDS patients in MSM.
