2010-2015年福建省戊型肝炎空间聚集性及变化规律研究

Spatial clustering and changing of hepatitis E in Fujian province, 2010-2015

  • 摘要: 目的 探索福建省戊型肝炎(戊肝)发病的空间聚集性、聚集区域及其变化趋势,为制定防控策略提供依据。方法 从中国疾病预防控制信息系统获取福建省2010-2015年戊肝监测资料,用SAS 9.2 软件进行频数计算等统计分析,用ArcGIS 10.2 软件对各县(区)发病率进行空间自相关分析。结果 2010-2015年福建省戊肝报告发病率介于2.34/10万~3.36/10万之间,年均发病率为2.85/10万。2010-2015年全局Moran's I依次为0.357、0.410、0.329、0.498、0.216和0.124,均P0.05。局部空间自相关分析,2010-2015年各年戊肝发病分别有8、8、6、11、8和9个热点区域,其中90.00%(45/50)的热点区域在三明市所辖县(区);83.33%(10/12)的三明市所辖县(区)在2010-2015年间成为热点区域。热点区域戊肝的发病水平、发病季节性、城乡分布和高发人群等特征与非热点区域间存在明显差异。结论 福建省戊肝发病存在空间聚集性,并具有一定程度的集中性、连续性和扩散趋势。三明市是防控的重点区域,应进一步深入调研其空间聚集的影响因素。

     

    Abstract: Objective To explore the spatial clustering, specific clustering areas and changing of clustering areas of hepatitis E in Fujian province, and provide evidence for hepatitis E prevention and control. Methods The surveillance data of hepatitis E during 2010-2015 in Fujian province were obtained from the national disease reporting information system and analyzed with SAS 9.2. The spatial autocorrelation analysis of hepatitis E incidence at county/district levels was performed with ArcGIS 10.2. Results The reported incidence of hepatitis E in Fujian ranged from 2.34/100 000 to 3.36/100 000 during 2010-2015, with the annual average of 2.85/100 000. The global Moran's I values were 0.357, 0.410, 0.329, 0.498, 0.216, 0.124 respectively (P0.05). The local spatial autocorrelation analysis indicated that there were 8, 8, 6, 11, 8 and 9 hot areas with high incidence of hepatitis E during this period respectively. Most hot areas were the counties or districts of Sanming (90.00%, 45/50). Most of the counties or districts of Sanming had become the hot areas with high incidence of hepatitis E during this period (83.33%, 10/12). The epidemiological characteristics of hepatitis E had obvious differences between hot areas and non-hot areas, such as the incidence level, seasonality, rural and urban distributions and population with high incidence. Conclusion The spatial clustering of hepatitis E was observed in Fujian with a certain degree of concentration, continuity and diffusion trend. The hepatitis E control and prevention measures should be strengthened in Sanming and the influencing factors of the spatial clustering should be further investigated.
