Factors associated with urinary incontinence in women.

Possible aetiological factors for urinary incontinence were examined in a prevalence study among a random sample of 1000 women aged 18 and over. Infective factors were not markedly associated with incontinence but mechanical factors such as parity and obesity were. No association was found, however, between a history of perineal damage at childbirth and incontinence. Women with incontinence had on average a higher score for a 'neuroticism' trait elicited by questionnaire than women without the disorder.
