Stress urinary incontinence: prevalence among nulliparous compared with primiparous and grand multiparous premenopausal women.
The study was conducted to assess the prevalence of stress urinary incontinence in premenopausal nulliparae, primiparae, and grand multiparae, and to examine possible obstetric risk factors. Three hundred consecutive nulliparae, primiparae, and grand multiparae, 20 to 43 years of age, were interviewed during the third postpartum day of their consequent delivery about the symptom of stress urinary incontinence. Women were asked whether they had experienced stress urinary incontinence before, during, or after previous pregnancies and how troubled they were by their incontinence. Details of general and gynecologic history, parity, mode of previous deliveries, and birth weights were sought. Main outcome measures included prevalence of pregnancy-related and (persistent) nonpregnancy-related stress urinary incontinence. Prevalence of persistent stress urinary incontinence was significantly higher in grand multiparae compared with nulliparae (21% vs. 5%, respectively; P = 0.0008). Prevalence of persistent stress urinary incontinence among grand multiparae who had been delivered of at least one baby weighing more than 4,000 g was significantly higher than in those who did not (29.4% vs. 16.7%, respectively). The birth weight of the first newborn and operative vaginal delivery were not found to be associated with increased risk of stress urinary incontinence. Grand multiparity was found to be associated with an increased risk of developing persistent stress urinary incontinence during reproductive ages. The delivery of at least one baby weighing more than 4,000 g seems to be a predominant factor. Neurourol. Urodynam. 18:419-425, 1999.
