Few studies have examined direct effects of food cues presented within television (TV) programs on eating behavior in adults. This research experimentally determined whether exposure to food cues in TV programs affects energy intake during TV viewing among young women, independently from food cues presented in TV advertisements. The experiment involved a 2 (TV program with or without food cues) by 2 (TV advertisements with or without food cues) between-participants design. While watching TV, participants could freely eat peanut chocolate candies and crisps (potato chips). Participants were 121 young women (mean age = 19.6 years; mean BMI = 22.5). Participants who watched a TV program with food cues tended to have a lower total energy intake and ate significantly less peanut chocolate candies than participants who watched the same TV program without food cues. This effect was particularly pronounced among participants with a higher BMI. Food advertisements did not affect energy intake. Findings may indicate that subtle continuous food cues during TV programs could make young females more aware of their own eating and/or weight, leading to reduced intake of particularly sweet snack foods during TV viewing. Considering the non-significant trend for the effect of the TV program with food cues on total energy intake, findings should be replicated to provide possible tools for prevention campaigns using food cue reminders to watch one's intake.
很少有研究检验电视节目中呈现的食物线索对成年人饮食行为的直接影响。本研究通过实验确定,在观看电视节目时,暴露于电视节目中的食物线索是否会影响年轻女性在观看电视时的能量摄入,而与电视广告中呈现的食物线索无关。该实验采用 2(有或没有食物线索的电视节目)×2(有或没有食物线索的电视广告)的被试间设计。在观看电视时,参与者可以自由食用花生巧克力糖和薯片(薯条)。参与者为 121 名年轻女性(平均年龄=19.6 岁;平均 BMI=22.5)。观看有食物线索的电视节目的参与者的总能量摄入往往较低,并且与观看没有食物线索的相同电视节目的参与者相比,食用的花生巧克力糖明显较少。对于 BMI 较高的参与者,这种影响更为明显。食物广告并不影响能量摄入。研究结果可能表明,电视节目中微妙的持续食物线索可能会使年轻女性更加意识到自己的饮食和/或体重,从而减少在观看电视时特别喜欢的甜食的摄入量。考虑到有食物线索的电视节目对总能量摄入的影响存在非显著趋势,应重复这些发现,为使用食物线索提醒来控制摄入量的预防活动提供可能的工具。
