【摘要】：目的探讨全国出生缺陷发病的空间分布特征,为出生缺陷的有效防控提供科学依据。方法建立全国1996—2012年出生缺陷发病数据库,利用普通克里金插值,生成全国出生缺陷发病水平图,对发病率进行空间自相关分析、趋势面分析和空间回归分析。结果全局自相关显示:全国出生缺陷1996—2004年(I=0.226,P=0.000 6)和2005—2012年(I=0.283,P=0.000 03)呈现空间聚集性;局部自相关指出了出生缺陷发病的"正热点"区域分别为广东、广西和福建,"负热点"区域分别为黑龙江、吉林和辽宁;趋势面分析显示:出生缺陷发病由西向东先增高再降低,由北向南逐渐增加;空间回归分析显示:发病率随着纬度的递增而降低。结论全国出生缺陷发病具有明显的地域分布规律,应针对不同区域制定相应的预防控制措施。
[Abstract]:Objective to explore the spatial distribution of birth defects in China, and to provide scientific basis for effective prevention and control of birth defects. Methods the database of birth defects in China from 1996 to 2012 was established and the common Kriging interpolation was used. The national birth defect incidence level map was generated, and the incidence rate was analyzed by spatial autocorrelation analysis, trend surface analysis and spatial regression analysis. Results the global autocorrelation showed that the birth defects in China from 1996 to 2004 (0.226) and 2005-2012 (0.283) showed spatial aggregation. Local autocorrelation indicated that the positive hot spots of birth defects were Guangdong, Guangxi and Fujian, and the negative hot spots were Heilongjiang, Jilin and Liaoning respectively. Trend surface analysis showed that the incidence of birth defects increased first and then decreased from west to east, and gradually increased from north to south. Spatial regression analysis showed that the incidence of birth defects decreased with the increase of latitude. Conclusion the incidence of birth defects in China has an obvious regional distribution, and corresponding prevention and control measures should be made for different regions.
