【摘要】 目的:探索2011~2013年河南省某县出生缺陷发生的空间分布规律。方法:引入空间权重矩阵的概念,对出生缺陷发生率进行空间经验贝叶斯平滑调整,采用全局、局部空间自相关分析方法进行分析。结果:在2011~2013年间出生缺陷发生率整体上呈现空间聚集性分布(P<0.05),2011~2013年,出生缺陷发生率高值聚集村数分别为10个、12个和15个。结论:该县出生缺陷发生具有空间聚集性,出生缺陷发生的聚集区表现出由东向西转移的趋势。更多还原

【Abstract】 Objective: To explore spatial distribution regularity of birth defects in a county of He’nan province from 2011 to 2013.Methods: A concept of spatial weight matrix was introduced and the incidence rate of birth defects was adjusted by spatial experience Bayesian smoothing. Global and local autocorrelation analysis were used to detect the spatial distribution of birth defects. Results: From 2011 to2013,the incidence rate of birth defects showed spatial aggregation distribution on the whole( P < 0. 05),the numbers of gathered villages with high incidence rate of birth defects were 10,12 and 15,respectively. Conclusion: The occurrence of birth defects in the county shows spatial aggregation. Accumulation area of birth defects shows the trend of transferring from east to west.更多还原
