产后腹直肌分离发生的影响因素研究

Risk factors for diastasis recti abdominis after delivery

目的:探讨产后发生腹直肌分离(DRA)的影响因素。方法:横断面选取2018年8月至2018年10月于北京大学人民医院产科定期产检并分娩,并于产后6~8周复查的产妇。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310例,其中DRA者108例,无DRA者202例,DRA发生率为34.84%(108/310)。阴道分娩者相对于剖宫产者,发生产后DRA的风险较小( OR =0.459,95% CI 为0.261~ 0.807 )。产后高BMI是DRA分离发生的保护因素( OR =0.796,95% CI 为0.717~ 0.883 ),新生儿出生体重大是DRA的危险因素( OR =1.001,95% CI 为1.000~1.002)。结论:经剖宫产分娩、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 affecting factors of diastasis recti abdominis(DRA) after delivery. Methods: Women were regularly examined and delivered in the obstetrics department of Peking University People's Hospital and were examined in the hospital for 6~8 weeks after delivery from Aug.2018 to Oct.2018.The incidence of postpartum DRA and its influencing factors were statistically analyzed. Results: A total of 310 parturients met the inclusion criteria,including 108 in the DRA group and 202 in the non-DRA group.The incidence of DRA was 34.84%(108/310).Analysis of risk factors for DRA showed that different delivery methods had different effects on the occurrence of postpartum DRA.Compared with cesarean section,vaginal delivery has a lower risk of postpartum DRA ( OR =0.459,95% CI :0.261~ 0.807 ).Postpartum high BMI was a protective factor for DRA ( OR =0.796,95% CI :0.717~0.883),and higher birth weight was a risk factor for DRA ( OR =1.001,95% CI :1.000~ 1.002 ). Conclusions: Cesarean delivery,high birth weight and low postpartum BMI were the risk factors for postpartum DRA.
