Medline ® Abstract for Reference 59

OBJECTIVE: The purpose of this study was to evaluate prospectively the association between selected obstetric antecedents and symptoms of pelvic floor dysfunction in primiparous women up to 7 months after childbirth.

STUDY DESIGN: All nulliparous women who were delivered between June 1, 2000, and August 31, 2002, were eligible for a postpartum interview regarding symptoms of persistent pelvic floor dysfunction. Responses from all women who completed a survey at or before their 6-month contraceptive follow-up visit were analyzed. Obstetric antecedents to stress, urge, and anal incontinence were identified, and attributable risks for each factor were calculated.

RESULTS: During the study period, 3887 of 10,643 primiparous women (37%) returned within 219 days of delivery. Symptoms of stress and urge urinary incontinence, were significantly reduced (P<.01) in women who underwent a cesarean delivery. Symptoms of urge urinary incontinence doubled in women who underwent a forceps delivery (P = .04). Symptoms of anal incontinence were increased in women who were delivered of an infant whoweighed>4000 g (P = .006) and more than doubled in those women who received oxytocin and had an episiotomy performed (P = .01).

CONCLUSION: The likelihood of symptoms of pelvic floor dysfunction up to 7 months after delivery was greater in women who received oxytocin, who underwent a forceps delivery, who were delivered of an infant who weighed>4000 g, or who had an episiotomy performed. Women who underwent a cesarean delivery had fewer symptoms of urge and stress urinary incontinence.
