Food-insecure populations experience increased risk for binge eating. This study examined how food insecurity contributes to development of binge eating during adolescence-a key period for its onset-alongside broader contributing factors in this life stage. Semi-structured qualitative interviews were conducted with 30 adolescents ages 12-19 years who reported past-year food insecurity (via the Child Food Insecurity Experiences Scale) and any past-month objective and/or subjective binge eating (via items from the Youth Eating Disorder Examination-Questionnaire). Grounded theory analysis yielded the "Co-occurring Insecurities Model", a new working theoretical model representing six interconnected themes: (1) co-occurring body image and food insecurities contributed to (2) internally and externally imposed deprivation of food, particularly desirable foods; binge-eating episodes tended to occur when (3) opportunities to eat desirable foods coincided with a drive to (4) satisfy current or anticipated hunger and/or (5) seek comfort from food to cope with life stressors/negative mood; and (6) binge eating often resulted in emotional, interpersonal, and/or physical discomfort. Results suggest binge eating in adolescents experiencing food insecurity is explained not only by factors known to contribute to binge eating in the general population (e.g., weight/shape concern-driven dietary restraint, negative mood), but also an instinct to seize opportunities to eat desirable foods when such opportunities are hard to come by. It may be important for binge-eating interventions in populations with food insecurity to increase food access and simultaneously acknowledge that binge eating may serve an adaptive function in the context of food insecurity but often has negative repercussions.
粮食不安全人群暴饮暴食的风险增加。本研究探讨了粮食不安全如何在青春期（暴饮暴食开始的关键时期）导致暴饮暴食的发展，以及这一生命阶段中更广泛的促成因素。对30名12至19岁的青少年进行了半结构化定性访谈，这些青少年报告了过去一年的粮食不安全状况（通过儿童粮食不安全经历量表）以及过去一个月内任何客观和/或主观的暴饮暴食情况（通过青少年饮食失调检查问卷中的项目）。扎根理论分析得出了“并发不安全模型”，这是一个新的工作理论模型，代表六个相互关联的主题：（1）身体形象和粮食不安全并发导致（2）内在和外在因素造成的食物匮乏，尤其是受欢迎的食物；当（3）有机会食用受欢迎的食物与（4）满足当前或预期饥饿和/或（5）从食物中寻求安慰以应对生活压力源/负面情绪的冲动同时出现时，往往会发生暴饮暴食事件；并且（6）暴饮暴食通常会导致情绪、人际和/或身体不适。结果表明，粮食不安全青少年的暴饮暴食不仅可以用已知的导致一般人群暴饮暴食的因素来解释（例如，对体重/体型的关注导致的饮食限制、负面情绪），还可以用在难以获得此类机会时抓住机会食用受欢迎食物的本能来解释。对于粮食不安全人群的暴饮暴食干预措施来说，增加食物获取机会并同时认识到暴饮暴食在粮食不安全背景下可能具有适应性功能，但往往会产生负面影响，这可能很重要。
