Abstract: Objective To analyze the clustering characteristics of birth defects in rural areas of Pingyin County,Shandong province from 2004 to 2016. Method The numbers of birth defects in each village were calculated,and were fitted by Poisson distribution and negative binomial distribution. Result The distribution of birth defects did not fit the Poisson distribution (χ2=30.33,P<0.001),but fit the negative binomial distribution (χ2=4.56,P=0.336). Conclusion The distribution of birth defects cases at village level presented spatial clustering in rural areas of Pingyin county through 2004-2016.

Key words: birth defects, Poisson distribution, negative binomial distribution, spatial clustering

摘要: 目的 分析山东省平阴县农村地区出生缺陷聚集性分布特征,为进一步病因学研究和防治提供线索和依据。方法 收集平阴县2004-2016年出生缺陷登记资料,描述出生缺陷地理分布,计算每个村庄的出生缺陷发病例数,对出生缺陷数据资料进行Poisson分布和负二项分布拟合优度检验。结果 出生缺陷发病数据不符合Poisson分布(χ2=30.33,P<0.001),但符合负二项分布(χ2=4.56,P=0.336)。结论 平阴县农村地区出生缺陷在村级层面上具有空间聚集性。
