Food insecurity is defined as lack of consistent access to adequate food for healthy living. The objective of this study was to determine the associations between food insecurity and binge-eating disorder in a national cohort of 9- to 14-year-old children.
We analyzed prospective cohort data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 10,035, 2016-2020). Logistic regression analyses estimated the associations between food insecurity at baseline, year 1, or year 2 (exposure) and binge eating, subclinical binge-eating disorder (Other Specified Feeding and Eating Disorder-Binge-Eating Disorder [OSFED-BED]), and binge-eating disorder (BED) (outcome) based on the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5) at 2-year follow-up.
The prevalence of food insecurity in the study was 15.8%. At 2-year follow-up, 1.71% of the sample received a diagnosis of BED or OSFED-BED, while 6.62% reported binge eating. Food insecurity was associated with 1.67 higher odds of BED or OSFED-BED (95% CI 1.04-2.69) and 1.31 higher odds of binge-eating symptoms (95% CI 1.01-1.71).
Food insecurity in early adolescence is associated with higher odds of developing future binge-eating and BED or OSFED-BED. Clinicians may consider assessing for binge eating in adolescents with food insecurity and provide support in accessing appropriate food resources.
Prior research has shown that food insecurity is associated with disordered eating behaviors, including binge eating in adulthood. This study explored whether food insecurity in early adolescence increases risk for developing binge-eating disorder (BED). Targeted screening for BED in adolescents experiencing FI, and vice versa, may be warranted.
食物不安全被定义为无法持续获得健康生活所需的充足食物。本研究的目的是在一个由 9 至 14 岁儿童组成的全国队列中，确定食物不安全与暴饮暴食障碍之间的关联。
我们分析了青少年大脑认知发展（ABCD）研究（N=10035，2016-2020 年）的前瞻性队列数据。基于两年随访时的儿童心境障碍和精神分裂症诊断性访谈表修订版（Kiddie Schedule for Affective Disorders and Schizophrenia-5，KSADS-5），使用逻辑回归分析估计了基线、第 1 年或第 2 年（暴露）的食物不安全与暴饮暴食、亚临床暴食障碍（Other Specified Feeding and Eating Disorder-Binge-Eating Disorder，OSFED-BED）和暴食障碍（Binge Eating Disorder，BED）（结局）之间的关联。
研究中食物不安全的患病率为 15.8%。在两年随访时，样本中有 1.71%的人被诊断为 BED 或 OSFED-BED，而 6.62%的人报告有暴饮暴食。食物不安全与 BED 或 OSFED-BED 的发病风险增加 1.67 倍（95%CI 1.04-2.69）和暴饮暴食症状的发病风险增加 1.31 倍（95%CI 1.01-1.71）相关。
青春期早期的食物不安全与未来发生暴饮暴食和 BED 或 OSFED-BED 的风险增加有关。临床医生可能会考虑在有食物不安全的青少年中评估暴饮暴食，并提供获取适当食物资源的支持。
先前的研究表明，食物不安全与饮食障碍行为有关，包括成年后的暴饮暴食。本研究探讨了青春期早期的食物不安全是否会增加发展为暴食障碍的风险。有必要针对经历食物不安全的青少年进行 BED 的针对性筛查，反之亦然。
