摘要
目的探讨云南不明原因猝死的家庭和村庄聚集性.方法选择2005年该病的52例监测病例作为研究对象,并采用Poisson分布和β-二项分布拟合病例在家庭中的分布,用Poisson分布和负二项分布拟合病例在村庄中的分布.结果病例在家庭中的分布服从β-二项分布(x^(2)=0.25,P=0.62),尤其是在人口数较少的家庭,但不服从Poisson分布(x^(2)=46.01,P<0.001);在村庄中的分布服从负二项分布(X^(2)=0.05,P=0.58),但不服从Poisson分布(X^(2)=110.57,P<0.001).结论云南不明原因猝死具有家庭和村庄聚集性.
Objective To discuss the clustering of Yunnan unexplained sudden death(YUSD)in household and village Methods Fifty-wo cases were found by YUSD sureillance system in 2005.Poisson distribution and beta-binomial distribution(BBD)were employed in studying the household distribution of the disease.Poisson distribution and negative binomial distribution(NBD)were employed in studying the village distribution of the disease.Results BBD were fitted household distribution of YUSD very well(X^(2)=0.25,P=0.62),while Poisson distribution was consistent with it(X^(2)=46.01,P<0.001).And NBD were fited village distribution of YUSD very well(X^(2)=0.05,P=0.58),however the consistenc in Poisson distribution was not observed(X^(2)=110.57,P<0.001).Conclusion Household and village clustering of YUSD does exist.
