[Prevalence of urinary incontinence among institutionalized persons aged 60 and over in Japan].
In order to estimate the prevalence of persons experiencing urinary incontinence among the institutionalized aged 60 and over in Japan, a questionnaire survey was conducted in 16 prefectures in February 1991. The questionnaires were distributed and collected by the nurses in hospitals and in other facilities. A total of 10,022 residents were asked to answer a questionnaire on their urinary incontinence condition and 9,798 responses were analysed. The main results were as follows; 1) The prevalence rate of urinary incontinence occurring almost daily in hospitalized persons aged 60 and over was 23.3% for men, 23.8% for women. 2) The prevalence rate of urinary incontinence occurring almost daily in institutionalized persons aged 60 and over in special nursing homes was 64.2% of the aged 60 and over for men, 67.9% for women. 3) The prevalence of urinary incontinence increased with age for both sexes especially in hospitalized persons. 4) The 95% confidence interval estimate for the number of the hospitalized over 60 years old suffering from almost daily urinary incontinent incidents was estimated to be from 31,000 to 113,000 in men and from 60,000 to 182,000 in women. 5) The 95% confidence interval estimate for the number of the institutionalized in special nursing home over 60 years old suffering from almost daily urinary incontinent incidents was estimated to be from 34,000 to 50,000 in men and from 97,000 to 119,000 in women. 6) The 95% confidence interval estimate for the number of the institutionalized over 60 years old suffering from almost daily urinary incontinent incidents was estimated to be from 318,800 to 570,600 in both sexes. 7) A random sampling survey is required to elucidate the actual state of prevalence in all generations. 8) Future research should emphasize the assessment of preventive and medical interventions, as incontinence is preventable and medical and surgical treatment options are available.
