目的：评估5-7岁女孩体重指数(BMI)变化的预测因素和儿童超重相关危险因素的家庭聚集性。方法：研究对象包括197名5岁女孩及其父母，其中192人在女孩7岁时被重新评估。评估了女孩体重指数变化的三类预测因子，包括女孩和父母的体重状况、饮食摄入量和体力活动。根据身高和体重测量计算女孩和父母的BMI以及BMI的变化。女孩的饮食摄入量使用三个24小时回忆来评估；父母的摄入量使用食物频率问卷来评估。女孩和母亲提供女孩身体活动的报告；父母通过自填问卷评估活动的频率和乐趣。结果：预测女孩5-7岁期间BMI变化的最有效模型包括儿童和父母的特征，特别是女孩5岁时的BMI，母亲BMI的变化，父亲的能量摄入，父亲对活动的享受，以及女孩从脂肪中获得的能量百分比。此外，研究结果显示，体重状况和饮食摄入量以及较少程度的体力活动与家庭内部的关系密切，家庭内部存在多种危险因素。结论：本研究结果强调了家庭在儿童超重病因中的中心地位，以及让父母参与儿童超重治疗的必要性。
Objective: This study assessed predictors of change in girls' body mass index (BMI) between ages 5 and 7y and familial aggregation of risk factors associated with childhood overweight.Method: Participants included 197 5-y-old girls and their parents, of whom 192 were reassessed when girls were 7-y-old. Three classes of predictors of girls' change in BMI were assessed including girls' and parents' weight status, dietary intake and physical activity. Girls' and parents' BMI and change in BMI were calculated based on height and weight measurements. Girls' dietary intake was assessed using three 24 h recalls; parents' intake was assessed using a food frequency questionnaire. Girls and mothers provided reports of girls' physical activity; parents' frequency and enjoyment of activity were assessed using a self-administered questionnaire.Results: The most effective model predicting girls' change in BMI between ages 5 and 7 included both child and parent characteristics, specifically girls' BMI at age 5, mothers' change in BMI, fathers' energy intake, fathers' enjoyment of activity, and girls' percentage of energy from fat. In addition, results showed substantial intra-familial associations in weight status and dietary intake and to a lesser extent physical activity, and the presence of multiple risk factors within families. Associations were also noted between girls' and parents' change in BMI.Conclusions: Results from this study highlight the centrality of the family in the etiology of childhood overweight and the necessity of incorporating parents in the treatment of childhood overweight.
