Recent research suggests that binge eating is a common experience in youth. However, it remains largely unknown how children's binge eating presents in everyday life and which psychological factors serve to maintain this binge eating.
Children aged 8-13 years with binge eating (n=59), defined as at least one episode of loss of control (LOC) over eating within the past three months, and 59 matched children without LOC history were recruited from the community. Following a combined random- and event-sampling protocol, children were interviewed about their day-to-day eating behavior, mood, and eating disorder-specific cognitions using child-specific cell phones during a 4-day assessment period in their natural environment.
LOC episodes led to a significantly greater intake of energy, particularly from carbohydrates, than regular meals of children with and without LOC eating. While LOC episodes were preceded and followed by cognitions about food/eating and body image, there was minimal evidence that negative mood states were antecedents of LOC eating.
The results provide support for the construct validity of LOC eating in children. Maintenance theories of binge eating for adults apply to children regarding eating disorder-specific cognitions, but the association with affect regulation difficulties requires further investigation.
近期研究表明暴饮暴食在青少年中是一种常见现象。然而，儿童暴饮暴食在日常生活中的表现以及哪些心理因素维持这种暴饮暴食现象在很大程度上仍不为人知。
从社区招募了8至13岁有暴饮暴食行为的儿童（n = 59），暴饮暴食定义为在过去三个月内至少有一次饮食失控（LOC）发作，以及59名匹配的无LOC病史儿童。按照随机抽样和事件抽样相结合的方案，在4天的评估期内，让儿童在自然环境中使用儿童专用手机，就其日常饮食行为、情绪和饮食失调相关认知接受访谈。
与有和没有LOC饮食的儿童的正常饮食相比，LOC发作导致能量摄入显著增加，尤其是碳水化合物的摄入。虽然LOC发作前后都有关于食物/饮食和身体形象的认知，但几乎没有证据表明负面情绪状态是LOC饮食的先兆。
研究结果为儿童LOC饮食的结构效度提供了支持。成人暴饮暴食的维持理论在饮食失调相关认知方面适用于儿童，但与情绪调节困难的关联需要进一步研究。
