INTRODUCTION AND HYPOTHESIS: The objective was to examine the relationship between maternal and perinatal factors and the occurrence of stress (SUI) or mixed (MUI) urinary incontinence (UI) 1 year after the first vaginal delivery in primiparous women.
METHODS: Participants in this prospective cohort were recruited consecutively from June 2003 to July 2005 from all eligible women who delivered in the department. A validated questionnaire, the International Consultation of Incontinence Questionnaire Short Form (ICIQ-SF) was completed by all participants 2-3 days after delivery, and a similar second questionnaire was filled out 1 year later. Additional data were obtained from the medical records. The first questionnaire was completed by 1,018 women (63 %) and the second by 859 women (84 %). The study group comprised the 575 women without any UI before the pregnancy and who had a vaginal delivery. The primary analysis comprised 117 women with either SUI or MUI 1 year after the vaginal delivery and 403 women without any UI.
RESULTS: In univariate analyses, the following factors were associated with SUI or MUI: prepregnancy body mass index (BMI) ≥ 30 (p < 0.05), UI during the pregnancy (p < 0.05), perineal lesions (p < 0.05), and anal sphincter tears (p = 0.05). Logistic regression analysis showed that SUI or MUI was strongly associated with UI during the pregnancy [adjusted odds ratio (OR) 4.7, 95 % confidence interval (CI) 2.9-7.7) and inversely associated with oxytocin augmentation (adjusted OR 0.5, 95 % CI 0.3-0.9).
CONCLUSIONS: SUI or MUI 1 year after the first vaginal delivery was strongly associated with UI during the pregnancy and inversely associated with oxytocin augmentation.
