Answer

The prevalence of enuresis gradually declines during childhood. Of children aged 5 years, 23% have enuresis. During elementary school years, 10% of 7-year-old children and 4% of 10-year-old children still experience enuresis. In adults, however, the reported prevalence of enuresis is 0.5-2%. A Korean epidemiologic study found that the overall prevalence of nocturnal enuresis in subjects aged 16-40 years was 2.6%. [13]

When PE and SE are reported, a secondary onset accounts for about 25% of cases. The prevalence of SE as a percentage of all cases increases with age. In a cohort of New Zealand children, 7.9% developed SE by the age of 10 years. [14]

Enuresis is more common in males. The reported prevalences of enuresis at the ages of 7 and 10 years are 9% and 7%, respectively, in boys and 6% and 3%, respectively, in girls. No racial predisposition has been documented.
