Loss of control (LOC) eating in children leads to excessive weight gain. However, few studies have investigated the eating behavior of children with LOC eating and psychological and familial factors that maintain the eating behavior.
This study sought to measure food intake in children with LOC eating and to examine maintenance through negative mood and parent-child mealtime interactions.
Children with or without LOC eating (n = 120, aged 8-13 y) consumed a parent-child test meal and a child-only meal, consisting of snack food, after the induction of negative mood. Food intake, mood, sense of LOC, hunger, satiety, and mealtime interactions were assessed.
Regardless of mood induction, children with LOC eating showed a greater intake of energy, fat, and protein and a greater sense of LOC than did those without LOC in the child-only snack group, which was accounted for by greater baseline hunger and satiety. Independently, children with high recurrent LOC eating had a greater food intake at both test meals than did those with low recurrent LOC eating. Overall, mealtime interactions did not differ between groups, but parents of children with LOC eating expressed more weight-related critique than did parents of children without LOC eating outside negative mood induction. Predictors of food intake were greater antecedent hunger or less satiety, stronger antecedent sense of LOC, and more weight-related critique.
The results showed objective abnormalities in the eating behavior of children with LOC eating that were mostly unrelated to negative mood or dysfunctional mealtime interactions. Further research is required to specify factors maintaining LOC eating.
儿童的失控性进食会导致体重过度增加。然而，很少有研究调查过具有失控性进食行为的儿童的进食行为，以及维持这种进食行为的心理和家庭因素。
本研究旨在测量具有失控性进食行为的儿童的食物摄入量，并通过负面情绪和亲子用餐互动来检查其维持因素。
有无失控性进食行为的儿童（n=120，年龄 8-13 岁）在负面情绪诱导后，分别食用了亲子测试餐和儿童单独用餐，包括零食，评估食物摄入量、情绪、失控感、饥饿感、饱腹感和用餐互动。
无论是否进行情绪诱导，具有失控性进食行为的儿童在儿童单独的零食组中，与没有失控性进食行为的儿童相比，摄入的能量、脂肪和蛋白质更多，失控感更强，这归因于更大的基线饥饿感和饱腹感。独立地，具有高频率失控性进食行为的儿童在两次测试餐中的食物摄入量均大于具有低频率失控性进食行为的儿童。总的来说，用餐互动在组间没有差异，但具有失控性进食行为的儿童的父母在负面情绪诱导之外，比没有失控性进食行为的儿童的父母表达了更多与体重相关的批评。食物摄入量的预测因素是更大的前摄性饥饿感或更小的饱腹感、更强的前摄性失控感以及更多的与体重相关的批评。
结果显示，具有失控性进食行为的儿童的进食行为存在客观异常，这些异常主要与负面情绪或功能失调的用餐互动无关。需要进一步研究来确定维持失控性进食行为的因素。
