Eating disorders (EDs) are associated with significant morbidity and mortality.1 The prevalence of early-onset EDs has increased in the past several decades, with younger children more likely than adolescents to experience psychiatric comorbidity. The single nationally representative study that has reported 12-month prevalence rates of EDs among children aged 8 to 15 years found 0.1% total for children aged 8 to 11 years, with 0.3% for girls and 0.1% for boys aged 8 to 15 years old.2 However, this previous study used Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) criteria and did not report the prevalence of specific ED diagnoses. The aims of the present study were to report the prevalence rates of anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other specified feeding and eating disorders (OSFED) in addition to a global “any ED” diagnosis, using Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5) criteria among a US representative sample of children aged 9 and 10 years. Prevalence rates were tested by participant sex.
