摘　　要：目的应用高频超声测量正常未育女性腹直肌间距(IRD),同时分析其相关因素。方法选取我院行健康体检的106名正常未育女性志愿者,体质量指数(BMI)均≤30 kg/m2,应用高频超声分别于仰卧位静息状态及卷腹动作测量脐上3 cm、脐部、脐下2 cm和脐下3 cm 4个位置的IRD,应用百分位数法计算IRD范围;分析IRD与年龄、身高、体质量、BMI的关系。结果正常未育女性仰卧位静息状态IRD值为:脐上3 cm为4~15 mm,脐部为5~20 mm,脐下2 cm为0~7 mm,脐下3 cm为0~3 mm,与卷腹动作时各值比较差异均无统计学意义。相关性分析显示,IRD与年龄、身高无相关性,与体质量和BMI呈弱正相关(r=0.20、0.27,P=0.04、0.01)。结论应用高频超声可准确检测正常未育女性IRD值,且IRD与体质量和BMI均呈弱正相关。ObjectiveTo measure the inter-rectus distance(IRD)in normal nulliparous women by high frequency ultrasound,and to analyze its correlated factors.MethodsA total of 106 healthy nulliparous women volunteers who underwent physical examination in our hospital were enrolled.All the enrolled volunteers with BMI≤30 kg/m2.High frequency ultrasound was used to measure the IRD at 4 locations(3 cm above the umbilicus,umbilicus,2 cm and 3 cm below the umbilicus)under the supine position and abdominal curling position.The range of IRD was calculated by percentile method,and the relationship between IRD and age,height,weight and BMI were analyzed.ResultsThe normal range of IRD at supine position was as follows:3 cm above umbilicus was 4~15 mm,umbilical level was 5~20 mm,2 cm below umbilicus was 0~7 mm,and 3 cm below umbilicus was 0~3 mm,there were no significant difference compared with the values of crunches.Correlation analysis showed that IRD had no correlation with age and height,but had weak positive correlation with weight and BMI(r=0.20,0.27,P=0.04,0.01).ConclusionHigh frequency ultrasound can accurately measure the IRD in normal nulliparous women,and IRD is weakly positively correlated with weight and BMI.
