Prevalence of substance use disorder in individuals with attention deficit/hyperactivity disorder: associations with sex and psychiatric comorbidity.

ABSTRACT:

Background

Several studies have reported associations between attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUD). However, sex-differences in ADHD and SUD, especially when associated with other psychiatric comorbidities, are less studied.

Individuals born 1988-2001 were identified and followed until 2019 (ages 18-31 years in 2019). Log binomial regression was used to calculate age-adjusted prevalence differences (PD
