Television viewing may contribute to obesity via promotion of sedentary behavior and exposure to food-related commercials. However, the mechanisms by which food-related commercials promote food intake are not well understood. Therefore, the purpose of the present study was to examine the impact of television advertisements on food intake according to sex and transportability, or the tendency to become engrossed in what one is viewing. Eighty-three undergraduate students, free of disordered eating symptoms, were stratified by sex and randomly assigned to one of three conditions (food-related advertisements, neutral advertisements, or no advertisements). They were then identified as high or low in transportability according to a median split. A significant interaction was found between advertisement condition and transportability such that those high in transportability ate more in the food than other advertisement conditions. A second interaction was found between sex and transportability with women high in transportability eating more food than women low in transportability irrespective of advertisement condition. No significant main effects of advertisement condition, sex, or transportability were found. Results suggest the importance of studying the impact of individual difference variables on the relationship between food-related advertising and food intake.
看电视可能会通过促进久坐行为和接触与食物相关的广告来导致肥胖。然而，人们对与食物相关的广告促进食物摄入的机制还不是很了解。因此，本研究的目的是根据性别和可转移性（即专注于所观看内容的倾向）来检验电视广告对食物摄入的影响。83 名没有饮食失调症状的本科生按性别分层，然后随机分配到三种条件之一（与食物相关的广告、中性广告或没有广告）。根据中位数分割，他们被确定为高或低可转移性。广告条件和可转移性之间存在显著的交互作用，即高可转移性的人在食物方面吃得更多，而其他广告条件则不然。还发现了性别和可转移性之间的第二个交互作用，即高可转移性的女性比低可转移性的女性吃得更多，而与广告条件无关。没有发现广告条件、性别或可转移性的显著主要影响。结果表明，研究个体差异变量对与食物相关的广告和食物摄入之间关系的影响的重要性。
