目的探测新疆地区结核病空间分布特征及其影响因素。方法采用空间经验贝叶斯平滑标化涂阳结核病报告率,绘制涂阳结核病发病等级地图;采用空间自相关分析与时空扫描统计量,探测新疆涂阳结核病的空间聚集性与时空聚集区域;采用地理加权回归解释新疆涂阳结核病报告数的空间分布非平稳性。结果新疆南疆地区涂阳结核病发病等级高于北疆地区,存在一定的空间相关性(全局Moran’I=0.276,P<0.001)与39个结核病高负担聚集地区,主要集中在南疆地区。同时,南北疆地区涂阳结核病发生均受社会经济学因素影响,全疆范围内少数民族人口比例是最主要的影响因素,南疆地区受社会经济学因素作用较大(局部R~2为0.71~0.90),局部R~2呈由西南向东北递减趋势。结论新疆结核病具有一定的空间聚集性,应重点结核病高负担聚集性区域的结核病健康教育,注意区域化防控策略的制定。
Objective To explore the spatial distribution of tuberculosis in Xinjiang and its influencing factors. Methods Spatial empirical Bayesian standardized smear-positive rate of smear-positive tuberculosis (TB) was used to map the incidence of smear-positive tuberculosis (TB). Spatial autocorrelation analysis and space-time scans were used to detect the spatial and temporal aggregation of smear-positive TB in Xinjiang. Geographic Weighted Regression to Explain the Spatial Distribution of Smear Positive Tuberculosis Report in. Results The prevalence of smear-positive tuberculosis in southern Xinjiang was higher than that in northern Xinjiang. There was a certain degree of spatial correlation (Moran’I = 0.276, P <0.001) and 39 high burden of tuberculosis in southern Xinjiang, mainly in southern Xinjiang. Meanwhile, the incidence of smear-positive tuberculosis in southern and northern Xinjiang is affected by socio-economic factors. The proportion of ethnic minorities in Xinjiang is the most important factor, and the social economy in southern Xinjiang is greatly influenced by the socio-economic factors 0.71 ~ 0.90). Local R ~ 2 showed a decreasing trend from southwest to northeast. Conclusion Tuberculosis in Xinjiang has a certain degree of spatial aggregation, and should focus on tuberculosis health education in areas with high burden of tuberculosis, pay attention to the formulation of regional prevention and control strategies.
