Observational study found pelvic floor dysfunction varies with BMI, showing overweight women report less dyspareunia post-injury.
Dyspareunia 12 months after an obstetric anal sphincter injury was less common among overweight and obese women than in normal-weight women. Self-reported anal incontinence one year after an obstetric anal sphincter injury was equally distributed over the BMI groups 12 months after delivery, which is a new finding and clinically relevant.
