The transition to college is considered as a risk period for the development of behavioral symptoms of eating disorders (BSEDs) and some evidence suggests that, amongst men, these symptoms occurring on a regular basis remain relatively stable over the college period. Nevertheless, little is known about factors associated with persistent engagement in and initiation of recurrent (or regular) binge eating and inappropriate weight compensatory behaviors in this population. The objective of this report was to address these research gaps.
Data were examined from 2,555 male first-year college students who completed an assessment of potential vulnerability factors and BSEDs at the beginning of the autumn semester (baseline) and nine months later (end of the spring semester; follow-up).
Elevated negative affectivity, body dissatisfaction, self-objectification, and lower self-esteem at baseline were predictive of persistent engagement in regular binge eating and four compensatory behaviors (self-induced vomiting, laxative/diuretic abuse, fasting, exercise) at follow-up, as well as initiation of all these behaviors occurring regularly (i.e., at least weekly for 3 months). Self-objectification (thinking and monitoring the body's outward appearance from a third-person perspective) emerged as the largest contributor of both the initiation and persistence of all behavioral symptoms.
Data emphasize that the same psychological factors underlie initiation and persistence of recurrent BSEDs and should shape the focus of future interventions for college men. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2016; 49:581-590).
向大学过渡被认为是饮食失调行为症状（BSEDs）发展的一个风险期，一些证据表明，在男性中，这些经常出现的症状在大学期间保持相对稳定。然而，对于该人群中与反复（或经常）暴饮暴食及不适当体重补偿行为的持续参与和开始相关的因素知之甚少。本报告的目的是填补这些研究空白。
对2555名大学一年级男生的数据进行了检查，这些学生在秋季学期开始时（基线）和九个月后（春季学期末；随访）完成了对潜在易患因素和BSEDs的评估。
基线时消极情感性增强、身体不满、自我客体化及自尊较低可预测随访时持续参与经常暴饮暴食及四种补偿行为（自我催吐、滥用泻药/利尿剂、禁食、运动），以及开始经常出现所有这些行为（即至少每周一次，持续3个月）。自我客体化（从第三人称视角思考和监测身体外观）成为所有行为症状开始和持续的最大促成因素。
数据强调，相同的心理因素是反复出现的BSEDs开始和持续的基础，应成为未来针对大学男生干预措施的重点。© 2016威利期刊公司（《国际进食障碍杂志》2016年；49:581 - 590）。
