[目的]研究甘肃省乙肝病毒感染标志的分布是否有家庭聚集性。[方法]2006年甘肃省乙肝血清流行病学抽样调查949户家庭,其中有605个乙肝病毒感染标志阳性病例,分布在398户家庭。本研究针对该数据,采用二项分布进行拟合。如果该数据不服从二项分布,则乙肝表面抗原的分布呈家庭聚集性。[结果]利用二项分布进行拟合,所得统计学检验P值分别为0.000 0,表明该数据不服从二项分布。[结论]甘肃省乙肝感染标志的分布呈家庭聚集性。
[Objective] To study whether the distribution of hepatitis B virus infection markers in Gansu Province had family aggregation. [Method] A total of 949 families were enrolled in the Gansu Provincial Serological Epidemiology Survey of Hepatitis B in 2006, of which 605 cases were positive for hepatitis B virus infection and distributed in 398 families. In this study, the data were fitted by binomial distribution. If the data do not obey binomial distribution, then the distribution of hepatitis B surface antigen was family aggregation. [Results] Using the binomial distribution for fitting, the P values of the statistical tests were 0.000 0, respectively, indicating that the data did not obey the binomial distribution. [Conclusion] The distribution of hepatitis B infection in Gansu Province was family aggregation.
