Abstract
Background
Diastasis of rectus abdominis (DRA) refers to a separation of the rectus abdominis from the linea alba. This study aimed to investigate the association with the severity of DRA for developing pelvic floor dysfunction among women during the first year postpartum.
Methods
This is a retrospective cohort study which collected data from 229 postpartum women. DRA was defined as a separation of ≥ 20 mm at any point 4.5 cm above, at and 4.5 cm below the umbilicus. The data for analysis includes pelvic organ prolapse quantification (POP-Q), medical history of urinary incontinence (UI), the strength of rectus abdominis muscle and pelvic floor muscle. The differences in women with and without DRA were compared with independent samples t-test and Chi-square test.
Results
Prevalence of DRA was 82.6% during the first postpartum year. Cesarean section and multiple parturitions are recognized as risk factors for DRA due to the odds ratio in our study were 3.48 (95% CI 1.42–8.56), 3.20 (95% CI 1.59–6.45) respectively. There was no difference in the occurrence of UI and pelvic organ prolapse (POP) comparing women with and without DRA, even changing the cut-off values (inter-rectus distance = 20 mm, 30 mm, 40 mm, 50 mm) for determining DRA. The women with weak rectus abdominis muscle and pelvic floor muscle have no statistical difference in two group.
Conclusion
The relationship of the diastasis recti abdominis and pelvic floor dysfunction has no connection, even with the severity of inter-rectus distance increasing.
