OBJECTIVE
To compare the characteristic meal patterns of adolescents with and without loss of control (LOC) eating episodes.
METHOD
The Eating Disorder Examination was administered to assess self-reported LOC and frequency of meals consumed in an aggregated sample of 574 youths (12-17 years; 66.6% female; 51.2% Caucasian; BMI-z: 1.38 ± 1.11), among whom 227 (39.6%) reported LOC eating.
RESULTS
Compared to those without LOC, youth with LOC were less likely to consume lunch and evening meals (p's < .05), but more likely to consume morning, afternoon, and nocturnal snacks (p's ≤ .05), accounting for age, sex, race, socio-economic status, BMI-z, and treatment-seeking status.
DISCUSSION
Adolescents with reported LOC eating appear to engage in different meal patterns compared to youth without LOC, and adults with binge eating. Further research is needed to determine whether the meal patterns that characterize adolescents with LOC play a role in worsening disordered eating and/or excessive weight gain.
目的
比较有和无失控（LOC）进食发作的青少年的特征性进食模式。
方法
在一个由 574 名青少年（12-17 岁；66.6%为女性；51.2%为白种人；BMI-z：1.38±1.11）组成的综合样本中，通过饮食失调检查评估自我报告的 LOC 和集中摄入餐数的频率，其中 227 名（39.6%）报告有 LOC 进食。
结果
与无 LOC 的青少年相比，有 LOC 的青少年更不可能吃午餐和晚餐（p<0.05），但更有可能吃早餐、下午和夜间零食（p≤0.05），这些差异与年龄、性别、种族、社会经济地位、BMI-z 和治疗寻求状况有关。
讨论
与无 LOC 的青少年和暴食症成年人相比，报告有 LOC 进食的青少年似乎存在不同的进食模式。需要进一步研究来确定有 LOC 的青少年的特征性进食模式是否会导致饮食失调恶化和/或体重过度增加。
