This study investigates the effects of peer influence on the food intake of overweight and normal-weight children. A mixed factorial design was employed, with children's weight status (overweight vs. normal-weight) as a between-subjects factor, and social context (alone vs. group) as a within-subjects factor. A total of 32 children (n=17 overweight and n=15 normal-weight) between the ages of 6-10 years participated in this study. Findings from the random regression model indicated that overweight children ate more when with others than when alone, while in contrast normal-weight ate more with others than they did when alone. Therefore, social context differentially impacts the eating behavior of overweight and normal-weight children. This study underscores differences in responses to the social environment between overweight and non-overweight youths, and suggests that social involvement may be an important tool in treatment and prevention programs for overweight and obesity.
本研究调查了同伴影响对超重和正常体重儿童食物摄入量的影响。采用了混合因子设计，将儿童的体重状况（超重与正常体重）作为组间因素，社会环境（单独与群体）作为组内因素。共有32名6至10岁的儿童（n = 17名超重儿童和n = 15名正常体重儿童）参与了本研究。随机回归模型的结果表明，超重儿童与他人在一起时比单独时吃得更多，而相比之下，正常体重儿童与他人在一起时比单独时吃得更多。因此，社会环境对超重和正常体重儿童的饮食行为有不同的影响。本研究强调了超重和非超重青少年对社会环境反应的差异，并表明社会参与可能是超重和肥胖治疗及预防项目中的一个重要工具。
