英文文献摘要:
In experimental studies, children exposed to television food ads chose less healthy snacks and consumed more food overall, as compared with children exposed only to ads for toys. These findings, however, do not indicate that TV viewing causes a decrease in diet quality or an increase in weight. Other factors correlated with TV watching, such as neighborhood and parent and child characteristics, may be more to blame. We estimate the effect of an additional hour of television on total calories and the quality of food consumed during a day for children 6 to 18 years old. This research is the first to use a first difference (fixed effects) estimation strategy to investigate the impact of television on daily food consumption among children in the United States.
在实验研究中,与只看玩具广告的儿童相比,看电视食品广告的儿童会选择不那么健康的零食,总体上会消费更多的食物。然而,这些发现并不表明看电视会导致饮食质量下降或体重增加。其他与看电视有关的因素,如邻里关系、父母和孩子的性格特征,可能是更多的原因。我们估算了6至18岁儿童一天中多看一小时电视对总热量和食物质量的影响。本研究首次使用第一差异(固定效应)估计策略来调查电视对美国儿童日常食物消费的影响。
