| 目的 应用高频超声测量未育女性在四个位置的腹直肌间距并分析相关因素，旨在初步制定正常腹直肌间距(IRD)的参考值范围。
方法 选取2019年6月至2019年9月在我院行健康体检的106名健康未育女性志愿者，体质量指数（BMI）均≤30kg/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3cm、脐部、脐下2cm和脐下3cm四个位置的IRD，应用百分位数法计算IRD参考值范围，并分析IRD与年龄、身高、体重、BMI指数之间的关系。
结果 未育女性仰卧位静息状态IRD正常值范围如下：脐上3cm为4~15mm，脐部为5~20mm，脐下2cm为0~7mm，脐下3cm为0~3mm。相关性分析显示IRD与年龄、身高无相关性，与体重和BMI指数呈较弱的正相关。
结论 本研究应用高频超声初步建立了未育女性IRD的参考值范围，为腹直肌分离的诊断提供了依据，IRD与体重和BMI指数呈较弱的正相关。 |

| Abstract: |
| Objective High frequency ultrasound was used to measure the inter-rectus distance at four reference points in nulliparous women. Methods A total of 106 healthy nulliparous female volunteers who underwent physical examination in our hospital from July 2019 to October 2019 were selected, and the BMI≤30kg/m2. High frequency ultrasound was used to measure the IRD at four locations, namely, 3cm above the umbilicus, at the umbilicus, 2cm below the umbilicus and 3cm below the umbilicus in supine position and abdominal curling position. The reference range of IRD was calculated by percentile method, and the relationship between IRD and age, height, weight and BMI index were analyzed.
Results The normal range of IRD at rest 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 under umbilicus was 0 ~ 3 mm. Correlation analysis showed that IRD had no correlation with age and height, but had weak positive correlation with body weight and BMI.
Conclusion In this study, high frequency ultrasound was used to establish the normal range of IRD in nulliparous women, which provided the basis for the diagnosis of diastasis recti. IRD was weakly positively correlated with body weight and BMI. |
