Diastasis recti abdominis and pelvic floor dysfunction in peri- and postmenopausal women: a cross-sectional study

Introduction: Diastasis recti abdominis (DRA) and pelvic floor dysfunction (PFD) occurs commonly with aging; however, little is known about what leads to these changes. Objective: We aimed to investigate and compare the presence or absence of DRA and PFD in peri- and postmenopausal women. Methods: This cross-sectional study involved 150 participants who answered questions on their sociodemographic and clinical profiles related to urinary and fecal incontinence and pelvic organ prolapse. Diastasis recti abdominis was diagnosed with a digital caliper. Results: Supra-umbilical diastasis occurred in 37.3% of cases, and 78.6% of participants with DRA had PFD. No significant differences existed between participants with and without DRA in terms of background and clinical variables. However, participants with DRA were 2.6 times more likely to have PFD than participants without DRA. Furthermore, the presence of DRA was significantly shown to be a risk factor for PFD on binary logistic regression analyses (p = .01, OR = 3.2). Conclusions: This cross-sectional study suggests that DRA is a predictive factor of PFD in women aged over 50 years.
