目的探讨儿童对大份量食物的易感性与食欲调节和肥胖的关系。方法对体重正常和肥胖的5-6岁非西班牙裔黑人儿童（n=100）进行四种不同份量的晚餐条件的观察；提供的所有食物（牛奶除外）的分量分别为：参考条件（100%）的100%（677千卡）、150%（1015千卡）、200%（1353千卡）或250%（1691千卡）。条件顺序随机分配给2-4个孩子，他们每餐一起吃饭。测量儿童身高和体重，并获得照顾者关于儿童食欲的报告。分层生长曲线模型用于估计膳食能量摄入与份量状况、儿童体重状况和食欲调节特征之间的关系，并控制人口统计学因素。结果总能量摄入随食物份量的增加而增加(P
ObjectiveDetermine the association of children's susceptibility to large food portion sizes with appetite regulation and obesity.MethodsNormal-weight and obese non-Hispanic black children (n=100) aged 5-6 years were observed in four dinner conditions of varying portion size; portions of all foods (except milk) offered were: 100% (677 kcal), 150% (1015 kcal), 200% (1353 kcal), or 250% (1691 kcal) of those in the reference condition (100%). Condition order was randomly assigned to 2-4 children who ate together at each meal. Child height and weight were measured and caregiver reports of child appetite were obtained. Hierarchical growth curve models were used to estimate associations of meal energy intake with portion size condition, child weight status, and appetite regulation traits, controlling for demographics.ResultsTotal energy intake increased across conditions of increasing food portion size (P
