摘　　要：目的了解2005-2012年南昌市乙型肝炎(简称乙肝)发病的时空聚集性特征,为当地乙肝防制工作提供新的思路。方法采用2005-2012年南昌市乙肝疫情报告数据,以疫情信息中的现住详细地址和诊断日期分别作为地理和时间变量,建立具有时空属性的数据库,通过SaTScan 9.1.1软件分析南昌市乙肝发病的时空聚集性特征。结果回顾性时-空扫描分析显示,2005-2012年南昌市乙肝的发病不是随机的,具有明显的时空聚集特征。研究期间,进贤县均属于一类聚集区;西湖区在2006、2011、2012三个年度均为二类聚集区,其他区县在个别年度也有时空聚集现象。结论南昌市2005-2012年乙肝的发病分布存在一定的时空聚集性,当地卫生机构应给予进一步关注。Objective To explore the spatial-temporal clusters of hepatitis B in Nanchang City, and to provide a new clue for disease prevention and control. Methods The data about incident cases of hepatitis B from 2005 to 2012 were used to establish a database with spatial attribute, meanwhile, residential address and diagnosis date were considered as geographical and temporal variables respectively. Space-time scan analysis was applied to test the possible clusters of hepatitis B in this area by SaTScan 9.1.1. Results Retrospective space-time analysis showed that there were some signifi- cant clusters in Nanchang City from 2005 to 2012, and the distribution about spatial-temporal of hepatitis B was not ran- dom. Jinxian County was the most likely cluster area throughout the study period. In 2006, 2011 and 2012, Xihu District was the secondary cluster area. In addition, there were some spatial-temporal areas in the other counties some time. Con- clusions There were some spatial-temporal clusters of hepatitis B in Nanchang City and the local health agency should give more attention.
