Gyhagen M, et al. - Via a Swedish nationwide matched cohort study of 14,335 women from 40–65 years old, all 20 years after birth, the contributors intended to estimate and compare the effect size of 1 pregnancy, 1 vaginal delivery, and the derived protective effect of cesarean delivery for different aspects of urinary incontinence. A parallel increase in urinary incontinence from 40–65 years of age in nulliparous and vaginally and cesarean delivered women was observed. Hence, both pregnancy and vaginal delivery suffered an increased risk of urinary incontinence in the long term. Women who were delivered by vaginal delivery or cesarean delivery, the age-related gap for urinary incontinence between nulliparous and primiparous was concluded as constant between parallel trajectories that spanned ages from 40–65 years. Unaltered and significant calculated protective effect of cesarean delivery during the same age interval was noted.
