摘要
目的确定 1995-2020 年河南省新报告艾滋病病例的空间聚集及其时间变化趋势，为艾滋病防控策略提供依据。研究方法从中国疾病预防控制信息系统获取河南省 1995-2020 年新报告艾滋病病例信息，描述其人口学特征、空间自相关性和变化趋势。该项目在县一级进行，使用 ArcGIS 10.2。研究结果空间自相关性分析表明，全球莫兰 I 指数为 0.249，全球格蒂斯-奥德 G 系数 ZG 值为 6.472（所有 PI 指数分别为 0.197、0.103、0.491、0.411 和 0.383），全球格蒂斯-奥德 G 系数 ZG 值为 6.472（所有 PI 指数分别为 0.197、0.103、0.491、0.411 和 0.383）。全球 Getis-Ord G 系数的 ZG 值分别为 4.580、3.386、10.246、8.378 和 8.093。全球空间相关性均具有显著的统计学意义（所有 PConclusions）：1995-2020年河南省新报告艾滋病病例中艾滋病疫情呈聚集上升趋势，高聚集区由驻马店市、周口市逐渐向南阳市、郑州市及其周边县/区扩展，表明河南省有必要加强这些地区的艾滋病防控工作。
[Spatial-temporal distribution of newly reported HIV/AIDS cases in Henan Province, 1995-2020].
Objective: To identify the spatial clustering and its temporal trends among newly reported HIV/AIDS cases in Henan Province during 1995-2020, and to provide evidence for strategies on prevention and control of the disease. Methods: Information about newly reported HIV/AIDS cases in Henan between 1995 and 2020 were obtained from China Information System for Disease Control and Prevention and to describe their demographic characteristics, spatial autocorrelation and changing trends. This program was conducted at county level, using the ArcGIS 10.2. Results: A total of 96 528 HIV/AIDS cases with complete current address information in counties (districts) were newly reported during 1995-2020 in Henan, and the spatial autocorrelation analysis showed that Global Moran's I index was 0.249, ZG value of the Global Getis-Ord G coefficient was 6.472 (all P<0.001), indicating that there was a high clustered positive spatial autocorrelation of HIV/AIDS. The newly reported HIV/AIDS cases from 1995 to 2000, 2001 to 2005, 2006 to 2010, 2011 to 2015, and 2016 to 2020 in Henan Province all exhibited high values of global spatial clustering. Their Moran's I indices were 0.197, 0.103, 0.491, 0.411 and 0.383, respectively. The ZG values of the Global Getis-Ord G coefficient were 4.580, 3.386, 10.246, 8.378 and 8.093, respectively. All of global spatial correlation were statistically significant (all P<0.001). The results of local spatial autocorrelation analysis showed that newly reported HIV/AIDS cases in Henan Province had high-high clustering areas at each time stage mentioned above. The number of high-high clustering counties/districts gradually increased from 6 in 2001-2005 to 21 in 2016-2020, spreading from Zhumadian City and Zhoukou City in southeast Henan to Nanyang City in southwest Henan, Zhengzhou City and its surrounding counties/districts in central Henan. Conclusions: In Henan Province, an increasing trend of clusters appeared on HIV epidemic among newly reported HIV/AIDS cases from 1995 to 2020, and high-high clustering areas gradually expanded from Zhumadian City and Zhoukou City to Nanyang City, Zhengzhou City and its surrounding counties/districts, indicating that it is necessary to strengthen the AIDS prevention and control programs in these areas in Henan.
