Purpose: Symptomatic Established Rectus Diastasis (SERD) of parity is reported to be associated with decreased health-related quality of life and body-image satisfaction. Correction of rectus diastasis with abdominoplasty (with muscle plication) has been shown to improve quality of life in patient reported outcome measures (PROMs) research. However, the impact of rectus diastasis and surgical correction on women’s body-image and health-related quality of life compared to normative values using the BODY-Q has not been previously demonstrated. Methods: This was a prospective study on Australian women over 18-years old with rectus diastasis of parity undergoing abdominoplasty with diastasis repair. Women with an inter-rectus distance of >30mm confirmed on ultrasound and symptoms such as back pain and/or urinary incontinence were included. The BODY-Q instrument was administered online pre-op and then at least 6-months post-op and means were compared. Pre- and post-op scores were also compared to published normative values for women matched for age and BMI. Ethical approval from SAC HREC. Results: 117 women underwent abdominoplasty for SERD. BODY-Q scores were significantly higher after surgery than pre-op values for all scales (p<0.001). Pre-op BODY-Q scores for all scales were significantly worse than normative values (p<0.001) except for social function, which was similar. Post-op, BODY-Q scores for all scales were significantly better than normative values (p<0.001), except for physical and sexual function which were similar to normative. Conclusions: Women with SERD demonstrate significantly worse body-image satisfaction and health-related quality of life compared to normative populations of women. Surgical correction with abdominoplasty results in statistically significant and clinically meaningful improvements in health-related quality of life measured by the BODY-Q, to the level of normative populations of women.
