The causes of diastasis recti abdominis is unclear, but a general belief of not only diastasis recti abdominis but pelvic floor dysfunction could lead to weak connective tissue. The main risk factors for diastasis of rectus abdominis are obesity, multiparity, fetal macrosomia, flaccid abdominal muscles and multiple pregnancies. As we know, the risk factors for POP and UI are involved in parity, advancing age, and obesity. Pelvic floor dysfunction (PFD) mainly includes pelvic organ prolapse (POP), urinary incontinence (UI), and sexual dysfunction. Some investigations showed DRA leads to a series of complications, including abnormal condition, lumbopelvic pain and external defects which result in lower body satisfaction. Due to the variety of hormone changes during pregnancy, the abdominal muscles stretch affect by relaxin, progesterone and estrogen. DRA is common in pregnancy and postpartum women. Numerous studies have described the prevalence of DRA was between 27 and 100% in the middle and late of pregnancy respectively, 30–68% in the postpartum period. The relationship of the diastasis recti abdominis and pelvic floor dysfunction has no connection, even with the severity of inter-rectus distance increasing.ĭiastasis of rectus abdominis (DRA) is a condition defined as a separation of the rectus abdominis from the linea alba. The women with weak rectus abdominis muscle and pelvic floor muscle have no statistical difference in two group. 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. 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. Prevalence of DRA was 82.6% during the first postpartum year. The differences in women with and without DRA were compared with independent samples t-test and Chi-square test. 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. DRA was defined as a separation of ≥ 20 mm at any point 4.5 cm above, at and 4.5 cm below the umbilicus. ![]() ![]() ![]() This is a retrospective cohort study which collected data from 229 postpartum women. This study aimed to investigate the association with the severity of DRA for developing pelvic floor dysfunction among women during the first year postpartum. Diastasis of rectus abdominis (DRA) refers to a separation of the rectus abdominis from the linea alba.
