这项实验研究调查了儿童的食物摄入量是否直接受到同龄人摄入量的影响，以及随着时间的推移，这是否取决于体重状况。这项研究包括在荷兰小学举行的两次会议。在第一次（社会建模）会议期间，参与者（N = 223）被要求与一名同性正常体重的同伙一起解决一个难题，该同伙被指示不吃任何东西，少量或大量。在第二阶段（大约两天后），参与者必须独自解决难题，而他们可以自由进食。这项研究涉及三个（没有，低，高联盟摄入量）由两个（正常体重，超重）参与者之间的设计。在第一次会议的互动效果表明，超重的儿童可能会被触发（过度）吃时，同伴吃了大量的零食，而正常体重的儿童的食物摄入量似乎取决于邦联是否真的吃，不管数量。在第一次会议期间制定的指导方针随着时间的推移而持续存在，并影响了第二次会议期间的食物摄入量，而正常和超重儿童之间的差异变得微不足道。同龄人可以树立一个榜样，什么样的食物摄入是适当的，这可能会影响长期的食物摄入。(C)2012爱思唯尔有限公司保留所有权利。
This experimental study investigated whether children's food intake is influenced by a peer's intake directly and over time and whether this depends upon weight status. The study consisted of two sessions taking place at Dutch primary schools. During the first (social modeling) session, the participants (N = 223) were asked to solve a puzzle with a same-sex normal weight confederate who was instructed to either eat nothing, a small or large amount. In the second session (about two days later), the participants had to solve the puzzle alone while they could freely eat. The study involved a three (no, low, high confederate intake) by two (normal weight, overweight) between-participants design. An interaction effect in the first session suggested that overweight children might be triggered to (over)eat when a peer eats a high amount of snack food, whereas the food intake of normal weight children seemed to depend on whether the confederate did actually eat, regardless of the amount. The guideline set during the first session persisted over time and influenced food intake during the second session, while differences between normal- and overweight children became insignificant. Peers can set an example as to what food intake is appropriate which could affect long-term food intake. (C) 2012 Elsevier Ltd. All rights reserved.
