The incidence of urinary incontinence was investigated through questionnaires sent to 952 healthy Japanese women aged 18 to 88 years. Thirty-two percent of them wetted the wear involuntarily. The incidence of urinary incontinence in parous women was significantly higher than that in nulliparous women. Parous women over the age of 40 years lost urine more frequently than those aged under 40 Menopause, history of enuresis, previous episodes of urinary tract infection and urinary symptoms were not related to the incidence of urinary incontinence. Most of incontinent women lost urine only with physical strain.
