最近发达国家儿童肥胖患病率的上升引起了政策关注。尽管据报道，成年人的家庭粮食不安全状况与体重之间存在显着的正相关关系，但从能量生理学文献中得知，能量需求取决于基础代谢率、人体测量指标和体力活动。因此，对体重和家庭粮食不安全评分之间的双向关系进行建模非常重要，特别是对于营养和能量需求不断变化的儿童而言。本文利用 7635 名美国幼儿纵向研究幼儿园一年级、三年级和五年级（1999-2003 年）儿童的纵向数据估计了儿童体重和体重指数以及家庭粮食不安全评分的动态随机效应模型。主要发现是，首先，体育锻炼和兄弟姐妹的数量显着（P
Recent increases in obesity prevalence among children in developed countries are of policy concern. While significant positive associations between households' food insecurity status and body weights have been reported for adults, it is known from the energy physiology literature that energy requirements depend on BMR, anthropometric measures and physical activity. It is therefore important to model the bi-directional relationships between body weights and households' food insecurity scores especially for children that have evolving nutrient and energy requirements. The present paper estimated dynamic random effects models for children's body weights and BMI, and households' food insecurity scores using longitudinal data on 7635 children in the USA enrolled in 1st, 3rd and 5th grades (1999-2003) of the Early Childhood Longitudinal Study-Kindergarten. The main findings were, first, physical exercise and numbers of siblings were significantly (P
