Food insecurity and binge‐eating disorder in early adolescence

Objective 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. Method 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. Results 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). Discussion 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. Public Significance 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.
