The course of binge eating in adolescence is variable, and little is known about factors maintaining binge eating behaviors. The current study sought to characterize the course of binge eating and identify psychosocial factors associated with its maintenance.
A population-based sample reported on binge eating, depression symptoms, self-esteem, and body satisfaction at 5-year intervals spanning early/middle adolescence (Time 1 [T1]), late adolescence/early young adulthood (Time 2 [T2]), and early/middle young adulthood (Time 3 [T3]). Logistic regression examined factors predicting maintenance or cessation of binge eating.
A total of 15.8% of participants with binge eating at T1 continued to report binge eating at T2, and 42.0% of participants with binge eating at T2 continued to report binge eating at T3. From T1 to T2, improvements in self-esteem predicted cessation of binge eating. From T2 to T3, cessation of binge eating was predicted by improved body satisfaction, greater decreases in depression symptoms, and greater improvements in self-esteem.
Binge eating is relatively stable from late adolescence/early young adulthood to early/middle young adulthood, but less so from middle/late adolescence to late adolescence/early young adulthood. Improvements in psychosocial functioning during this timeframe may improve the outcome of binge eating, although mechanisms responsible for psychosocial changes (e.g., treatment involvement) require further investigation. Self-esteem appears to be a particularly salient factor involved in binge eating cessation and should be targeted in prevention and treatment programs.
青少年时期暴食行为的病程多变，而维持暴食行为的因素知之甚少。本研究旨在描述暴食行为的病程，并确定与其维持相关的心理社会因素。
一项基于人群的样本在青少年早期/中期（时间 1 [T1]）、青少年晚期/成年早期早期（时间 2 [T2]）和青少年早期/中期成年早期（时间 3 [T3]）之间以 5 年为间隔报告了暴食、抑郁症状、自尊和身体满意度。逻辑回归检验了预测暴食行为持续或停止的因素。
共有 15.8%的 T1 时存在暴食行为的参与者在 T2 时继续报告暴食行为，而 42.0%的 T2 时存在暴食行为的参与者在 T3 时继续报告暴食行为。从 T1 到 T2，自尊的改善预测了暴食行为的停止。从 T2 到 T3，暴食行为的停止由身体满意度的改善、抑郁症状的更大下降和自尊的更大改善来预测。
从青少年晚期/成年早期早期到青少年早期/成年早期中期，暴食行为相对稳定，但从中期/晚期青少年到青少年晚期/成年早期早期，暴食行为的稳定性较低。在此时间范围内心理社会功能的改善可能改善暴食行为的结果，尽管负责心理社会变化的机制（例如治疗干预）需要进一步研究。自尊似乎是与暴食行为停止相关的一个特别重要的因素，应在预防和治疗计划中作为目标。
