DESCRIPTION (provided by applicant): Peer Influence on Eating Behavior in Overweight and Normal Weight Youths. Although most eating occurs in a social context, the effects of peer influence on child eating have not been the object of systematic experimental study. The proposed experiment assesses the effects of peers on food intake and food choices in overweight and normal weight youths. A mixed design with weight status, gender and peer's weight status as between factors and the social context (alone versus dyad) as within factor will be used to compare youths' food consumption when alone and when in the presence of a peer. The prediction is that both the social condition and the peer weight status will have an impact on overweight participants' food selection and food consumption. More specifically, overweight participants will select more nutrient-dense food items and suppress their overall food intake in the presence of a leaner peer, but will select more calorie dense foods and consume more kilocalories in the presence of an overweight peer or when alone. Given the well documented sex differences in weight-related issues, 1, 2 we predict that female participants will be more likely to suppress their eating in the presence of a peer. It is expected that this effect will be more pronounced in overweight girls, who would attempt to avoid the stigma of "eating too much". This study is designed to understand differences in responses to the social and food environment between overweight and non overweight youths.

描述（由申请人提供）：同伴对超重和正常体重青年的饮食行为的影响。尽管大多数饮食发生在社会环境中，但同伴影响对儿童饮食的影响并不是系统性实验研究的对象。拟议的实验评估了同龄人对超重和正常体重青年中食物摄入和食物选择的影响。具有体重状况，性别和同伴的体重状况的混合设计是因素与社会环境之间（仅与二元组）之间的体重状况，将用于比较年轻人在单独和同伴存在的情况下比较年轻人的粮食消费。预测是，社会状况和同伴体重状况都会影响超重参与者的食物选择和食物消费。更具体地说，超重的参与者将选择更多营养丰富的食物，并在瘦弱的同伴存在下抑制其整体食物摄入量，但会选择更多卡路里浓密的食物，并在有超重的同伴或独自一人的情况下消耗更多的千瓦。鉴于与体重相关的问题有充分的性别差异，我们预测，在同伴存在下，女性参与者将更有可能抑制自己的饮食。预计这种影响在超重的女孩中会更明显，她们会试图避免“吃得太多”的污名。 这项研究旨在了解超重和非超重青年对社会和食物环境的反应差异。
