Our objective was to determine the prevalence of urinary incontinence in women assisted in the general outpatient clinic of the Botucatu School Health Center - UNESP. In the period from January 1996 to December 1997, 807 women were interviewed about urinary incontinence symptoms and to identify potential predisposing risk factors. The prevalence of urinary incontinence was of 29% of the cases, and in 9.2 % of the cases urinary leak to the minimum efforts. Of these patients only 30 % used protection. The urgency was associated to the urinary incontinence in 59.2% of the cases. The patients were divided in two groups depending on the presence or not of urinary leak. The mean age in the groups G1 ( incontinent women ) was of 52.9% years and in the group G2 ( continent women ) was of 49.9 years (p<0.05). The body mass index (BMI) in the group G1 was on the average of 27.5%, while, in the group G2 was of 25.8% ( p<0.05). Previous hysterectomy or history of fecal incontinence did not influence the occurrence of urinary leak. We concluded that the factor age has influence in the urinary leak, as well as the obesity measured by BMI.
