虽然大多数饮食发生在社会背景下，同伴的影响对儿童的食物消费和选择健康和不健康的零食的影响还没有系统的实验研究的对象。本实验评估了同伴互动对18名超重和21名非超重青少年能量摄入和食物选择的影响。参与者可以获得高热量和低热量的食物，并提供几个游戏作为饮食的替代品。一次，参与者单独接受测试，另一次，他们与一个不熟悉的同龄人一起接受测试。与以前的结果一致，我们发现超重儿童在独自一人时比在同伴面前吃得更多，并且在相同条件下独自一人时比瘦孩子吃得更多。非超重青少年的食物摄入量不受社会环境的影响。研究结果还表明，参与者是否食用健康零食的最佳预测因素是，二人组中的其他年轻人是否也食用健康零食。这些发现表明，同伴的存在可以影响超重儿童的能量摄入，也影响超重和非超重儿童的健康食物选择。
Although most eating occurs in a social context, the impact of peer influence on child food consumption and selection of healthy and unhealthy snacks has not been the object of systematic experimental study. The present experiment assessed the effects of peer interaction on energy intake and food choices in 18 overweight and 21 non-overweight youth. Participants had access to high and low-calorie food items and were provided with several games as alternatives to eating. On one occasion, participants were tested alone and on another occasion they were tested in dyads with an unfamiliar peer. Consistent with previous results, we found that overweight children ate substantially more when alone than when in the presence of a peer and also more when alone than the lean children in the same condition. Non-overweight youths' food intake was unaffected by the social context. Findings also indicated that the best predictor of whether participants consumed healthy snack foods was if the other youth in the dyad also consumed healthy snack foods. These findings suggest that the presence of peers can influence overweight children's energy intake and also influence healthier food selection in both overweight and non-overweight children.
