摘要
目的:应用多水平模型(Multilevel Model,MLM)分析南京市家庭急性上呼吸道感染调查数据,分析个体发病次数的影响因素及家庭的随机效应。方法:分布函数采用Poisson分布和负二项分布,参数估计为迭代广义最小二乘法。结果:本次调查影响个体发病次数的因素为年龄<14岁,既往有呼吸道疾病史的个体发病次数较多,而健康状况好的发病次数较少。家庭间存在随机效应,家庭内个体发病的相关系数为0.2左右。结论:多水平模型分析具有层次结构特征数据,可以提供更多的信息。
Objective: To study acute upper respiratory tract infection with the method of multilevel model (MLM) and analyze the influential factors of the incidence in families and family's random effect. Method: The response variable is fitted with Poisson and negative binomial distributions, and the coefficient is estimated with IGLS. Results. It was found that those who are less than 14 years; had history of chronic respiratory system disease are higher risk population of ARI, while the incidence was lower for those who are in good health condition. Conclusion: The data with clusters can give more information when the method is MLM.
