Nocturnal Enuresis -- American Family Physician

Epidemiology At five years of age, 15 to 25 percent of children wet the bed. With each year of maturity, the percentage of bed-wetters declines by 15 percent. Hence, 8 percent of 12-year-old N octurnal enuresis is a common problem, affecting an estimated 5 to 7 million children in the United States and occurring three times more often in boys than in girls. Unfortunately, only about one third of the families of children with this frequently troubling problem seek help from a physician. Recent studies have provided more information about nocturnal enuresis, and generally effective treatments are available.
