The Hordaland women’s cohort: prevalence, incidence, and remission of urinary incontinence in middle-aged women

Original Article

Abstract

Introduction and hypothesis

The aim of study is to prospectively investigate the prevalence, incidence, and remission of urinary incontinence (UI) in a cohort of middle-aged women.

Methods

In 1997–1999, 2,229 randomly selected women aged 41–45 agreed to participate in the Hordaland Women’s Cohort, and six almost identical postal questionnaires were sent them during the following 10 years. Response rate was 95.7% at inclusion and has remained 87% to 93% in subsequent waves; 64.1% answered all six questionnaires. UI variables include type, amount, frequency, and severity.

Results

Prevalence of UI increased by age until a peak in age group 51–52 years for any (50.3%) and significant (10.0%) UI. There was then a decrease in prevalence caused by a decrease in incidence and decrease in remission. Stress UI was the major type and most UI was of low severity.

Conclusion

Prevalence of any UI is high in middle-aged women but reaches a peak followed by a decrease.
