Diastasis of the rectus abdominis muscles in postpartum: Concordance of patient and clinician evaluations, prevalence, associated pelvic floor symptoms and quality of life

Abstract

ObjectivesThe main objective was to assess the reliability of the patient's measurement of diastasis. The secondary aims were the estimation postpartum diastasis prevalence, of diastasis-associated pelvic floor symptoms and quality of life immediately after childbirth and at 3−6 months postpartum. Study designUsing a prospective observational design, women who gave birth in a French university hospital were eligible. After a learning phase, both clinician and patient conducted a clinical evaluation of diastasis. Then, patients were asked to complete the HerQLes, the FPFQ and a general questionnaire. Three to 6 months later, patients completed the same questionnaires online and performed a clinical evaluation of diastasis at home, as learned previously. ResultsOf 253 patients included in the study, 139 (54.9 %) completed the questionnaires at 3–6 months of follow-up. There was good correlation between clinician and patient evaluations of diastasis (kappa coefficient 0.76 [95 % CI, 0.5−0.7]). Immediately after childbirth, 210 (83 %) of the women presented diastasis including 116/210 (55 %) cases of severe diastasis and 51 (42 %) of those had persistent diastasis at 3−6 months of follow-up. Cesarean section (p = 0.05) and multiparity (p = 0.04) were factors of persistent diastasis. Severe diastasis had a significant impact on quality of life (HerQLes score) at birth (p = 0.001) and at 3−6 months (p = 0.01), but no effect on pelvic floor symptoms according the FPFQ. The occurrence and severity of diastasis did not significantly impact lumbar or pubic symphysis pain. Furthermore, the aesthetic discomfort felt by patients was significantly increased by the presence of diastasis on a numerical scale at 3−6 months (p = 0.03). ConclusionGood agreement between clinician and patient evaluations of postpartum diastasis indicated that the evaluation method is reliable. Persistent diastasis was associated with impaired quality of life.
