摘　　要：目的通过高频超声测量腹直肌宽度,探讨产后腹直肌(DRA)分离发生率及影响因素。方法选取我院康复科就诊并于分娩后42~56天的产妇994例,采用高频超声测量其腹直肌间距,通过统计分析得出产后腹直肌分离发生率,并对其影响因素进行分析。结果994例中根据腹直肌分离情况分为两组,DRA组662例,无DRA组332例,腹直肌分离发生率为66.6%。根据产次划分,经产妇腹直肌分离率76.4%(279/365)高于初产妇60.9%(383/629),P<0.05,差异有统计学意义;根据生产方式划分,剖宫产腹直肌分离率72.2%(415/575),2次及以上剖宫产者83.3%(130/156),明显高于经阴道分娩者58.9%(247/419),P<0.05,差异有统计学意义。独立危险因素有检查时低BMI(P<0.05,OR=0.695,95%CI为0.294~1.642),新生儿出生体重大(P<0.05,OR=1.001,95%CI为1.000~1.001)等。结论产后腹直肌分离的危险因素有分娩次数增加,剖宫产,低BMI,新生儿出生体重过大等。Objective To investigate the incidence and influencing factors of postpartum rectus abdominis muscle separation by measuring the width of rectus abdominis muscle separation with high-frequency ultrasound.Methods Women who visited the rehabilitation Department of Maternal and 994 cases between 42 and 56 days after delivery were selected to measure the interval of rectus abdominis muscle by high-frequency ultrasound.The incidence of postpartum rectus abdominis muscle separation was obtained through statistical analysis,and the influencing factors were analyzed.Results A total of 994 cases of parturient women meeting the criteria were selected.According to the rectus abdominis muscle isolation,they were divided into two groups:662 cases in DRA group and 332 cases in non-DRA group.The incidence of rectus abdominis muscle isolation was 66.6%.The separation rate of rectus abdominis muscle in parturient women was 76.4%(279/365),higher than that in primipara women,(60.9%,383/629),P<0.05,and the difference was statistically significant.The rate of rectus abdominis muscle separation in caesarean section was 72.2%(415/575),and that of two or more cesarean sections was 83.3%(130/156)that was significantly higher than that of vaginal delivery(58.9%,247/419),P<0.05,and the difference was statistically significant.Independent risk factors included low BMI at examination(P<0.05,OR=0.695,95%CI 0.294~1.642)and hign borth weight(P<0.05,OR=1.001,95%CI 1.000~1.001).Conclusion Postpartum risk factors for rectus abdominis muscle separation include increased number of points,dissection,and low BMI.Newborn birth weight is too large.
