背景：超重和肥胖是日益严重的问题，最近人们越来越关注压力在这些临床问题的发生和维持过程中的作用。然而，其机制尚不为人所知和充分理解；而诸如压力和饮食之间的日常变化之类的生态瞬时分析的研究则少得多。情绪化饮食非常普遍，被认为是一种重要的机制，作为一种适应不良的情绪调节（ER）策略，启动和维持（儿童）肥胖的恶性循环。 目的：本研究旨在调查青少年（10-17岁）压力与自我报告的饮食行为轨迹（渴望吃的动机；饥饿的饮食动机和吃零食）之间的日常关系，为期1周；以及情绪调节和情绪化饮食在平均体重人群中的调节作用。方法：参与者为 109 名年龄在 10 岁至 17 岁之间的平均体重青少年（M 年龄 = 13.49；SD = 1.64）。孩子们在开始研究前在家填写了一份关于情绪调节和情绪化饮食的特质问卷，并在放学后连续7天回答了在线日记。连续七天每天评估进食欲望动机、饥饿进食动机和吃零食。结果：使用多水平分析结果显示，日常压力与进食欲望动机和饥饿进食动机的轨迹显着相关。没有发现证据表明适应不良的 ER 在这些关系中发挥调节作用；研究发现，情绪化饮食在进食欲望和吃零食的轨迹中起着调节作用，这一点具有轻微的意义。讨论：这些结果强调了研究压力和饮食行为参数之间日常关系的重要性，因为两者都与几天内的变化有关。需要更多的研究来得出关于 ER 策略和情绪化饮食的调节作用的明确结论。
Background: Overweight and obesity are growing problems, with more attention recently, to the role of stress in the starting and maintaining process of these clinical problems. However, the mechanisms are not yet known and well-understood; and ecological momentary analyses like the daily variations between stress and eating are far less studied. Emotional eating is highly prevalent and is assumed to be an important mechanism, as a maladaptive emotion regulation (ER) strategy, in starting and maintaining the vicious cycle of (pediatric) obesity.Objectives: The present study aims to investigate in youngsters (10 - 17 years) the daily relationship between stress and the trajectories of self-reported eating behavior (desire to eat motives; hunger eating motives and snacking) throughout 1 week; as well as the moderating role of emotion regulation and emotional eating in an average weight population.Methods: Participants were 109 average weighted youngsters between the age of 10 and 17 years (M-age = 13.49; SD = 1.64). The youngsters filled in a trait-questionnaire on emotion regulation and emotional eating at home before starting the study, and answered an online diary after school time, during seven consecutive days. Desire to eat motives, hunger eating motives and snacking were assessed daily for seven consecutive days.Results: Using multilevel analyses results revealed that daily stress is significantly associated with trajectories of desire to eat motives and hunger eating motives. No evidence was found for the moderating role of maladaptive ER in these relationships; marginally significant evidence was found for the moderating role of emotional eating in the trajectories of desire to eat and snacking.Discussion: These results stress the importance of looking into the daily relationship between stress and eating behavior parameters, as both are related with change over and within days. More research is needed to draw firm conclusion on the moderating role of ER strategies and emotional eating.
