Adolescence is a critical period for the emergence of eating disorders, and food insecurity may be related to eating pathology and weight, as evidenced in adults. However, little is known about food insecurity and eating pathology during this developmental period, and associations between food insecurity and body mass index (BMI) are mixed. Therefore, we examined associations between food insecurity and BMI percentile, self-reported eating-related pathology and binge eating, and subgroup differences by race/ethnicity. In a subset, we examined the relationship between food insecurity and real-world hunger, food craving, and loss-of-control eating using ecological momentary assessment (EMA). Fifty-eight adolescents at two sites (clinical sample, = 38, BMI percentile ≥ 70th; community sample, = 20, all BMI strata) completed self-report questionnaires. Adolescents were 15.2 ± 2.1 years old, 62% female, 50% Black, 34.5% Hispanic, with BMI percentile = 80.5 ± 25.8 (range 4-99). In the full sample, food insecurity was associated with greater BMI ( < 0.01), higher shape/weight overvaluation ( = 0.04), and greater number of binge eating episodes among those reporting at least one binge episode ( 0.01), with significant relationships for BMI percentile, shape/weight overvaluation, body dissatisfaction, and binge episode frequency among Hispanic adolescents only (each < 0.01). As in adults, food insecurity may be a risk factor for eating pathology, particularly for Hispanic teens.
青春期是饮食失调出现的关键时期，食物不安全可能与成人饮食病理学和体重有关。然而，在这个发展阶段，对于食物不安全与饮食病理学之间的关系知之甚少，而且食物不安全与体重指数（BMI）之间的关联也存在差异。因此，我们研究了食物不安全与 BMI 百分位、自我报告的饮食相关病理和暴食行为之间的关系，以及按种族/民族划分的亚组差异。在一个子集中，我们使用生态瞬时评估（EMA）研究了食物不安全与现实饥饿、食物渴望和失控进食之间的关系。两个地点的 58 名青少年（临床样本，n=38，BMI 百分位≥70 分；社区样本，n=20，所有 BMI 分层）完成了自我报告问卷。青少年的年龄为 15.2±2.1 岁，62%为女性，50%为黑人，34.5%为西班牙裔，BMI 百分位为 80.5±25.8（范围 4-99）。在全样本中，食物不安全与更高的 BMI（<0.01）、更高的体型/体重高估（=0.04）以及报告至少一次暴食行为的个体中更多的暴食发作次数相关（<0.01），在西班牙裔青少年中，BMI 百分位、体型/体重高估、身体不满和暴食发作频率均存在显著相关性（均<0.01）。与成人一样，食物不安全可能是饮食病理学的一个风险因素，特别是对西班牙裔青少年而言。
