产后腹直肌分离发生的影响因素

The influencing factors of rectus abdominis muscle separation after delivery

目的:探讨产后6周发生腹直肌分离(DRA)的影响因素。方法:选取于福州市第一医院产科定期产检并分娩,并于产后6周复查的初产妇,统计分析产后DRA发生率及其影响因素。结果:符合入组标准的产妇共500例,其中DRA者329例,无DRA者171例,DRA发生率为65.8%(329/500)。正常龄(年龄24~35岁)产妇分娩者相对于大龄产妇(年龄>35岁)发生产后DRA的风险较小(OR=0.334,95%CI为0.223~0.731)。产后高体重指数(BMI)是DRA分离发生的保护因素(OR=0.811,95%CI为0.721~0.867),新生儿出生体重大(>400 g)是DRA的危险因素(OR=1.002,95%CI为1.000~1.003)。结论:大龄产妇分娩、新生儿出生体重过大及产后低BMI是产后DRA的高危因素。

Objective To investigate the influencing factors of rectus abdominis separation(DRA) at 6 weeks postpartum. Method The cross-section selected primiparous women who had undergone regular obstetrics and delivery at the Obstetrics Department of Fuzhou First People′s Hospital, and were re-examined 6 weeks after delivery. Statistical analysis of the incidence of postpartum DRA and its influencing factors. Results A total of 500 pregnant women met the enrollment criteria, including329 cases of DRA and171 cases of non-DRA. The incidence of DRA was65.8%(329/500). Compared with normal-age women who give birth, older women who give birth had a lower risk of developing DRA(OR=0.334, 95% CI 0.223~0.731). High postpartum BMI was a protective factor for DRA separation(OR=0.811, 95% CI 0.721~0.867), and birth weight(>400 g)was a risk factor for DRA(OR=1.002, 95% CI is 1.000~1.003). Conclusion Delivery of older mothers, excessive birth weight of newborns, and low postpartum BMI are high risk factors for postpartum DRA.
