To measure attention to food cues following a multitask or a sustained attention single task, and further, to examine the associations with current weight status and excess consumption.
Ninety-six 13-to 17-year-olds were fed a standardized meal and then had their attention to food cues measured following completion of a single sustained attention task, media multitask, or a passive viewing control task. Participants then completed an eating in the absence of hunger paradigm to measure their excess consumption. Adolescents completed each condition on separate visits in randomized order. Attention to food cues was measured by computing eye-tracking measures of attention, first fixation duration, and cumulative fixation duration to distractor images while participants played the video game, Tetris. Participants also had their height and weight measured.
Although not statistically significant, attention to food cues was greatest following a media multitask and weakest following a task that engaged sustained attention when compared to a control. First fixation duration was positively and statistically significantly associated with BMI-Z when measured following a multitask. Cumulative fixation duration was not associated with BMI-Z. There were no associations between BMI-Z and attention to food cues after the attention or control task, nor any association between attention to food cues and eating in the absence of hunger.
Among adolescents, we found that current adiposity was related to attention to food cues following a multitask. Multitasking may perturb the cognitive system to increase attention to food cues.
测量在执行多任务或持续注意力单一任务后对食物线索的关注度，并进一步研究其与当前体重状况和过度进食之间的关联。
96名13至17岁的青少年先食用一顿标准化餐食，然后在完成一项持续注意力单一任务、媒体多任务或被动观看控制任务后，测量他们对食物线索的关注度。参与者随后完成了一项非饥饿状态下的进食范式，以测量他们的过度进食情况。青少年以随机顺序在不同的访视中完成每种情况。通过计算参与者玩俄罗斯方块视频游戏时对干扰图像的眼动追踪注意力测量值、首次注视持续时间和累积注视持续时间，来测量对食物线索的关注度。参与者还测量了身高和体重。
与对照组相比，尽管无统计学意义，但在媒体多任务后对食物线索的关注度最高，而在持续注意力任务后最低。在多任务后测量时，首次注视持续时间与BMI-Z呈正相关且具有统计学意义。累积注视持续时间与BMI-Z无关联。在注意力或控制任务后，BMI-Z与对食物线索的关注度之间无关联，对食物线索的关注度与非饥饿状态下的进食之间也无关联。
在青少年中，我们发现当前肥胖与多任务后对食物线索的关注度有关。多任务处理可能会干扰认知系统，增加对食物线索的关注度。
