行为经济学提供了一个框架来理解选择。目前还没有关于超重和非超重儿童的食物和社会活动之间的相互关系的研究。本研究的目的是用行为经济学的方法来检验超重和非超重青少年的食物和社会互动的可替代性。54(24男30女)超重和非超重的青少年,年龄在9至11岁进行了测试,使用的行为选择范式,参与者的反应,以赚取积分交换食物和/或社会活动。当与不熟悉同伴的社交时间成本增加时,青年用食物代替社交活动(p<0.05),当食物成本增加时,用食物代替与不熟悉同伴的社交活动(p<0.05)。然而,当与朋友互动是另一种选择时,参与者并没有用食物代替社交互动。社会互动可以作为一种替代品的食物在瘦和超重的青年。
Behavioral economics offers a framework to understand choice among alternatives. There is no research on the interrelationship between food and social activity in overweight and non-overweight children. The purpose of this study is to test the substitutability of food and social interactions using behavioral economic methods in overweight and non-overweight youth. Fifty-four (24 males and 30 females) overweight and non-overweight youth aged 9 to 11 years old were tested using a behavioral choice paradigm which involved participants responding to earn points exchangeable for food and/or social activity. Youth substituted food for social activities when the cost of social time with an unfamiliar peer increased (p<0.05) and substituted food for social activities with an unfamiliar peer when the cost of food increased (p<0.05). However, when interacting with a friend was the alternative, participants did not substitute food for social interactions. Social interactions can serve as a substitute for food in both lean and overweight youth.
