Objective: To evaluate whether antepartum pelvic floor muscle strength, as measured by the Brink scale, predicts postpartum anal incontinence.
Study design: This prospective cohort study of primigravid women used validated questionnaires and standardized pelvic examinations to evaluate subjects during the third trimester and at 2 postpartum time points.
Results: Of the initial 129 subjects, 102 and 81 completed 2 week and 6 month postpartum visits. 35% had cesarean deliveries. The antepartum prevalence of fecal incontinence (14%) did not differ significantly from the postpartum (17% at 2 weeks, 11% at 6 months). However, the prevalence of flatal incontinence fell from antepartum (65%) to postpartum (47% at 2 weeks, P = .001; 49% at 6 months, P = .012). Mean Brink score decreased postpartum; no correlations were found between Brink score and questionnaire scores.
Conclusion: Anal incontinence symptoms are common in the third trimester of a first pregnancy and may regress or resolve after delivery. Brink score did not predict postpartum anal incontinence.
