Prevalence of anal incontinence during pregnancy and 1 year after delivery in a cohort of primiparous women and a control group of nulliparous women.

This prospective cohort study showed remarkably high prevalences of AI during pregnancy and 1 year after delivery in primiparous women and likewise in nulliparous women at baseline and 1 year later. These results may indicate that factors other than pregnancy and delivery are of importance for AI in young women.
