我国西南地区细菌性痢疾发病热点分布特征及相关环境因素关系

Spatial distribution of hot spots of bacterial dysentery and related environmental factors in southwestern China

  • 摘要:
    目的 探讨我国西南地区细菌性痢疾(菌痢)发病的空间分布特征与相关自然环境和社会经济因素空间分布的关系。
    方法 利用中国传染病报告管理信息系统2005 — 2014年西南地区(四川省、云南省、西藏自治区)菌痢报告数据及气象数据、地形环境和社会经济因素,进行空间热点和冷点聚集性分析及环境因子的相关分布。
    结果 四川省中西部由北向南延伸至云南省西北角的条带区域及西藏自治区东南部区域为持续的菌痢高发区域。热点和冷点区域所涵盖县(区)的气象要素、地形环境和社会经济要素因子均存在显著性差异。热点地区的气温、降雨量和湿度水平均低于冷点地区,与以往大多研究不一致。热点地区为少数民族聚居区域,地形和经济发展水平是该区域菌痢发病的主要影响因素。
    结论 我国西南地区菌痢发病冷、热点分布特征与气象、地形、经济、社会、人文等指标密切相关,需要多因素综合分析探讨疾病关系,对特定地区应采取针对性措施才能有效控制菌痢的流行。

     

    Abstract:
    Objective To explore the spatial distribution characteristics of the bacillary dysentery in southwestern China and its relationship with natural environment and socio-economic level.
    Methods The incidence data of bacillary dysentery from 2005 to 2014 collected from China infectious disease reporting system, meteorological data, the geographic environment and the socio-economic data in southwestern provinces (Sichuan, Yunnan, and Tibet) were used to analyze the spatial distribution of hot spots and cold spots of bacillary dysentery clusters and its relationship with environmental factors.
    Results From 2005 to 2014, the incidence of bacillary dysentery was high in an area extending from mid-western Sichuan to northwest corner of Yunnan and southeast area of Tibet. There were significant differences in meteorological factors, geographic environment and socio-economic factors between hot spot and cold spot areas. The air temperature, precipitation and relative humidity in hot spot areas were lower than those in cold spot areas, which was inconsistent with the results of most previous studies. The hot spots were mainly in ethnic minority area, where geographic environment and economic development level were the main factors affecting the incidence of bacillary dysentery.
    Conclusion The spatial distribution of cold and hot spots of bacillary dysentery in southwestern China were closely related to meteorological, topographical, economic, social and cultural factors. Multi-factor comprehensive analysis is needed to discuss the relationship between the disease and environment, and it is necessary to take targeted measures in key areas to control the epidemic of bacillary dysentery effectively.
