目的 探讨梅毒流行的空间分布模式,为梅毒监测与防治提供新方法.方法 建立2011年中国各县区梅毒疫情地理信息系统数据库,使用探索性空间分析方法对中国梅毒疫情进行频数分布、全局和局部空间自相关分析,探索其空间分布特征.结果 2011年全国2 925个县区梅毒发病率中位数为21.17/10万(25％分位数9.28/10万,75％分位数43.00/10万),最小为0.00,最大为515.34/10万,呈明显的正偏态分布(偏度为3.11).全局空间自相关分析显示中国县区级梅毒疫情呈正空间自相关(全局Moran指数为0.5762,P＜0.001),空间分布模式为“高-高”聚集(全局G系数为0.0331,P＜0.001).通过局部自相关分析输出了中国县区级梅毒疫情分布的热点地图,确认了117个一、二期梅毒疫情的热点县区(其发病率均超过50/10万),主要分布于华东、西北、东北和华南等地区.结论 地理信息系统和探索性空间分析方法具有可视化和精确定位等优点,可作为一种新的重要工具用于梅毒监测和防治.
目的 探討梅毒流行的空間分佈模式,為梅毒鑑測與防治提供新方法.方法 建立2011年中國各縣區梅毒疫情地理信息繫統數據庫,使用探索性空間分析方法對中國梅毒疫情進行頻數分佈、全跼和跼部空間自相關分析,探索其空間分佈特徵.結果 2011年全國2 925箇縣區梅毒髮病率中位數為21.17/10萬(25％分位數9.28/10萬,75％分位數43.00/10萬),最小為0.00,最大為515.34/10萬,呈明顯的正偏態分佈(偏度為3.11).全跼空間自相關分析顯示中國縣區級梅毒疫情呈正空間自相關(全跼Moran指數為0.5762,P＜0.001),空間分佈模式為“高-高”聚集(全跼G繫數為0.0331,P＜0.001).通過跼部自相關分析輸齣瞭中國縣區級梅毒疫情分佈的熱點地圖,確認瞭117箇一、二期梅毒疫情的熱點縣區(其髮病率均超過50/10萬),主要分佈于華東、西北、東北和華南等地區.結論 地理信息繫統和探索性空間分析方法具有可視化和精確定位等優點,可作為一種新的重要工具用于梅毒鑑測和防治.

Objective To characterize the spatial distribution pattern of syphilis at the county level in China,and to provide a new method for syphilis surveillance and control.Methods A national geographic information system (GIS) database was developed based on reported cases of syphilis from all counties in China,2011.Exploratory spatial data analysis (ESDA) methods were used to study the frequency distribution of incidence,global and local spatial autocorrelation,of syphilis.Results The median incidence rate of syphilis was 21.17/100 000 (range:0.00-515.34/100 000; 25th percentile 9.28/100 000,75th percentile 43.00/100 000) in 2 925 counties in the mainland of China in 2011,with a highly positively skewed distribution (skewness =3.11).The global spatial autocorrelation analysis showed a positive spatial autocorrelation of syphilis incidence at the county level in China (global Moran's index =0.576 2,P ＜ 0.001),with the type of correlation being high-high cluster (General G index =0.033 1,P ＜ 0.001).The local spatial autocorrelation analysis delineated hot spots of syphilis (including primary and secondary syphilis,latent syphilis) at the county level.Totally,117 counties,which were mainly distributed in the Yangtze River delta region,northwest,northeastern and south China,were identified as hot spots for syphilis,with the incidence rate of primary or secondary syphilis being higher than 50/100 000.Conclusions The GIS and exploratory spatial data analysis,with the advantages of visualization and accurate localization,may serve as an important novel tool for syphilis surveillance and control.
