Consistent with previous research indicating greater comorbidity risk in males compared to females (24, 93), samples with a higher proportion of males were associated with higher comorbidity rates of any psychiatric disorder, ADHD, bipolar disorder, psychosis, specific phobia, agoraphobia, and ODD. Surprisingly, we did not find a higher prevalence of tic disorders and substance use disorders among males. The lack of a gender association in mood and anxiety disorder prevalence was also consistent with previous work (24, 93, 94); however, unlike previous reports, we did not find a higher prevalence of eating disorders in females (95).
