Prevalence of urinary incontinence.

TLDR

Incontinence is a common, often unrecognized symptom, suggesting substantial room for improved management. The study estimated prevalence by reviewing records from health and social service agencies in two London boroughs and conducting a postal survey of 22,430 adults from 12 general practitioner lists nationwide. Agency records show 0.2%–2.5% prevalence in women and 0.1%–1.3% in men, whereas a postal survey of 22,430 residents revealed 8.5%–11.6% in women and 1.6%–6.9% in men, with higher rates in older adults and those with ≥4 births, and only about one‑fifth of sufferers reporting moderate or severe symptoms and fewer than one‑third receiving care.

Abstract

The prevalence of urinary incontinence was investigated by determining the number of incontinent patients under the care of various health and social service agencies in two London boroughs and by a postal survey of the 22 430 people aged 5 years and over on the practice lists of 12 general practitioners in different parts of the country. The prevalence of incontinence known to the health and social service agencies was 0.2% in women and 0.1% in men aged 15-64 and 2.5% in women and 1.3% in men aged 65 and over. The postal survey, to which 89% of the people whose correct address was known replied, showed a prevalence of urinary incontinence of 8.5% in women and 1.6% in men aged 15-64 and 11.6% in women and 6.9% in men aged 65 and over. Nulliparous women had a lower prevalence than those who had had one, two, or three babies, but within the parity range of one to three there were no differences in prevalence. The prevalence was appreciably increased in women who had had four or more babies. Incontinence was moderate or severe in a fifth of those who reported it in the postal survey, of whom less than a third were receiving health or social services for the condition. Incontinence is a common symptom, and many unrecognised cases appear to exist. There may be considerable scope for improving its management.
