Abstract

Aim: Attention-deficit hyperactivity disorder (ADHD) and disordered eating (DE) are both highly prevalent among adolescents, but their relationship is understudied. This study examines their possible association in a nationally representative sample of adolescents.

Methods: Participants in the Israeli Youth Health and Nutrition Survey (2015-2016), a cross-sectional, school-based study, completed self-administered questionnaires, including the SCOFF questionnaire, and underwent anthropometric measurements. An affirmative reply to at least two SCOFF items was considered a DE case. Multivariable logistic regression evaluated the ADHD-DE association and the associations between ADHD and individual SCOFF items, controlling for age, sex, socioeconomic status, and body mass index.

Results: Of 4616 participants (12-18 years, 50.2% male), 654 reported an ADHD diagnosis. DE prevalence among ADHD adolescents was significantly higher than the non-ADHD group (50.2% vs. 43.9%, p = 0.003). Controlling for potential covariates, the association between ADHD and DE remained significant (OR = 1.409; 95% CI: 1.170-1.697), as did associations between ADHD and three SCOFF items. No difference in DE prevalence was found between stimulant-treated (n = 287) and untreated (n = 326) adolescents with ADHD.

Conclusion: Adolescents with ADHD are more likely to experience DE. As DE can herald an imminent eating disorder, early identification is crucial. Further studies are needed to determine the ADHD-DE relationship's causality.

Impact: Disordered eating (DE) and attention-deficit hyperactivity disorder (ADHD) are common among adolescents, and significantly affect health and well-being. This study examined the association between ADHD and DE in adolescents using the SCOFF questionnaire. Following adjustment for sociodemographic variables and BMI z-score, ADHD was associated with a 41% increased odds for DE. This study established the association between ADHD and DE, using a well-known questionnaire, in a large, nationally representative sample of adolescents. Monitoring eating behaviors and attitudes among adolescents with ADHD should be a priority, to minimize the risk of developing an eating disorder and its harmful consequences.
