[A survey on urinary incontinence among middle aged and older people].

Objective: Studies in Western countries have revealed that urinary incontinence, non-intentional loss of urine, is a common condition in aged populations, and even younger individuals may suffer from urinary incontinence. However, in Japan, the evidence for community residents on this topic is limited. The aim of this study was to estimate the prevalence of urinary incontinence among middle aged using a structured questionnaire and older people and to provide useful information including frequency, voided volume, relation to parity as a risk factor and persons to consult for this condition.
