Prevalence of urinary incontinence

Area of Science:

• Urology
• Public Health
• Epidemiology

Background:

• Urinary incontinence (UI) is a prevalent condition with significant impact on quality of life.
• Understanding the true prevalence of UI is crucial for effective healthcare planning and resource allocation.

Purpose of the Study:

• To investigate the prevalence of urinary incontinence in the general population.
• To compare UI prevalence known to health services versus self-reported prevalence.
• To explore factors influencing UI prevalence, such as age, sex, and parity.

Main Methods:

• A postal survey of 22,430 individuals aged 5 years and over across different UK regions.
• Analysis of data from health and social service agencies in two London boroughs.
• Inclusion of demographic data and parity information in the survey.

Main Results:

• Postal survey revealed higher UI prevalence (8.5% women, 1.6% men aged 15-64; 11.6% women, 6.9% men aged 65+) compared to agency data (0.2% women, 0.1% men aged 15-64; 2.5% women, 1.3% men aged 65+).
• Nulliparous women had lower UI prevalence than those with 1-3 children; prevalence increased significantly with 4+ children.
• Moderate to severe UI reported by a fifth of survey respondents, with less than a third receiving services.

Conclusions:

• Urinary incontinence is a common condition with a substantial number of unrecognized cases.
• There is considerable scope for improving the recognition and management of urinary incontinence.
• Parity is a significant factor in female urinary incontinence prevalence.
