Enuresis in children with attention-deficit hyperactivity disorder.

We did a retrospective study of the prevalence of nocturnal and diurnal enuresis in patients with attention-deficit hyperactivity disorder (ADHD). Patients with ADHD were identified at a referral center for developmental pediatrics. Control patients were identified at a general pediatric and pediatric allergy clinic. Adjusting for differences in sex and current age, ADHD children at age 6 were 2.7 times more likely than controls to have nocturnal enuresis and 4.5 times more likely to have diurnal enuresis. Results at children's current age were consistent with results at age 6; however, these differences were not statistically significant. Nocturnal and diurnal enuresis was found to be significantly more common in children with ADHD than in control subjects. Physicians who treat patients with ADHD should routinely inquire about the presence of enuresis.
