Abstract: Objective To investigate the current status of postpartumdiastasis recti abdominis (DRA) in puerpera 6-8 weeks after childbirth and analyze its influencing factors. Methods Convenience sampling method was used to collect 489 puerpera as the research objects in the postpartum rehabilitation clinic of a tertiary grade-A hospital in Shandong Province from July 2020 to January 2021. General data of puerpera were collected by questionnaire survey. Pelvic floor EMG value of puerpera was measured by Glazer evaluation, and DRA was assessed by palpation using finger breaths. Binary logistic regression was used to analyze the main influencing factors of postpartum DRA. Results The prevalence of postpartum DRA was 61.6%(301/489), including 225 mild cases, accounting for 74.8%（225/301）,65moderate ones for 21.5%（65/301）, and 11 severe ones for 3.7%（11/301）. Older maternal age, vaginal delivery, mixed feeding and higher neonatal body weight were independent risk factors for postpartum DRA (P<0.05). Conclusion The prevalence of postpartum DRA is high, and more attention should be paid to factors such as older maternal age, vaginal delivery, mixed feeding and newborns with high body weight. Medical staff should pay attention to DRA and take targeted prevention and intervention measures in perinatal period to reduce the occurrence and development of DRA after delivery.
