OBJECTIVE
This study aimed to determine the effects of concurrent and prior media use on dietary intake and dietary compensation over 3 days in a free-living population.
METHODS
Participants recorded food intake and media use for a 3-day period. The US Department of Agriculture multiple-pass method was used to ensure completeness of food records. Energy, protein, fiber, carbohydrates, sugar, added sugar, fat, saturated fat, trans fat, and sodium intake were assessed.
RESULTS
Meals consumed while participants used media included 149.3 more calories on average than meals consumed without media. Media meals were higher in protein, carbohydrates, fat, and saturated fat. There was no evidence of dietary compensation at the meal following the media meal.
CONCLUSIONS
Energy and macronutrient intake increased during media-paired meals. Dietary compensation at the subsequent meal did not occur, suggesting that the effects of media-paired meals are additive over the short term.
目的
本研究旨在确定在自由生活人群中，同时和之前使用媒体对 3 天内饮食摄入和饮食补偿的影响。
方法
参与者记录了 3 天内的饮食摄入和媒体使用情况。美国农业部多次通过法被用来确保食物记录的完整性。能量、蛋白质、纤维、碳水化合物、糖、添加糖、脂肪、饱和脂肪、反式脂肪和钠的摄入量都进行了评估。
结果
参与者在使用媒体时所吃的餐平均比不使用媒体时所吃的餐多摄入 149.3 卡路里。有媒体的餐食中蛋白质、碳水化合物、脂肪和饱和脂肪含量更高。在紧随媒体餐之后的那一顿饭，没有证据表明有饮食补偿。
结论
在有媒体相伴的餐食中，能量和宏量营养素的摄入增加。后续餐没有发生饮食补偿，这表明短期内媒体相伴的餐食的影响是累加的。
