Age-related long-term effects of vaginal delivery, pregnancy, and sphincter injury on anal continence: A matched cohort study.

The age‐related increase in FI was threefold in the subgroup of women with OASI ( n = 116), but this trend did not reach statistical significance (OR per 10 years, 2.10; 95% CI, 0.81–5.44; p = 0.13) (Figure 2B and Table S2B ). 4 DISCUSSION Long‐term fecal incontinence was more common and severe after vaginal delivery, particularly when complicated by obstetric anal sphincter injury, which doubled the risk and affected nearly one in four women with OASI.
