Risk Factors

About 13 million adults experience incontinence at some time. The number, however, may actually be higher because most patients are reluctant to discuss incontinence with their doctors. In fact, research indicates that many patients will not admit to having the problem even when questioned directly. Although a third of American men and women ages 30 to 70 have experienced at least some loss of bladder control, most have not been diagnosed by a doctor.

A 2004 survey of more than 1,400 Americans found that despite the prevalence of bladder control loss, an alarming 64% of those experiencing symptoms are not currently taking measures to manage their condition. The survey, sponsored by the National Association for Continence, also found that adults waited an average of 6 years before discussing their symptoms with a doctor. A 2006 study reported that only half of women with urinary incontinence have discussed their condition with a doctor and only a third had received any treatment.

Incontinence in Children and Young People

Incontinence is uncommon in children 5 years and older. However, it may still occur in:

10% of 5 year-olds
5% of 10 year-olds
1% of 18 year-olds

Incontinence that occurs before puberty is twice as common in boys as in girls. Most young people who experience nighttime wetting do not have any serious physical or emotional disorders. It is often difficult to diagnose incontinence in children. Many cases result from a combination of factors, including:

Birth defects or inborn conditions that cause problems in the urinary tract
Slower physical development
An overproduction of urine at night
A lack of ability to recognize bladder filling when asleep
Anxiety
Inherited factors (indicated by a strong family history of bedwetting)

Bedwetting in children is not considered incontinence. However, bedwetting and other urinary problems in childhood may predict the later development of adult urinary incontinence. According to a 2006 study, women who experienced childhood bedwetting, as well as frequent daytime and nighttime urination, had an increased risk of developing adult urge incontinence.
