【摘要】：目的评价绝经后女性腹部脂肪和椎旁肌肉与骨密度的相关性。方法选取2016年4月至2016年10月就诊于我院的绝经后女性75例,年龄45~83(62.2±9.1)岁,应用DXA(dual-energy X-ray absorptiometry,DXA)测量腰椎骨密度,再对受检者行腹部CT扫描,并在后处理工作站选定平脐水平的CT片,勾画出腹部脂肪和椎旁肌肉的面积。为了进一步分析,将样本根据体重指数分为2组,A组18.5≤BMI24,B组BMI≥24。结果腰椎骨密度与体重指数、腹部皮下脂肪、腹部内脏脂肪、腹部总脂肪、腰大肌及竖脊肌均呈正相关(r=0.264,P=0.022;r=0.244,P=0.035;r=0.286,P=0.013;r=0.298,P=0.009;r=0.371,P=0.001;r=0.258,P=0.025)。通过将BMI(body Mass Index)分为2组后得到结果:A组骨密度主要与腰大肌和竖脊肌呈正相关(r=0.479,P=0.011;r=0.424,P=0.028),B组骨密度主要与内脏脂肪和总脂肪呈正相关(r=0.318,P=0.028;r=0.339,P=0.019)。结论目前研究结果表明,对于绝经后女性而言,腹部脂肪和椎旁肌肉对骨密度具有保护作用,适当的体育锻炼和保持正常的体重更有利于预防骨质疏松症。
[Abstract]:Objective to evaluate the correlation between abdominal fat and paravertebral muscles and bone mineral density (BMD) in postmenopausal women. Methods 75 postmenopausal women, aged 45 to 83 years, aged 62.2 卤9.1 years, were selected from April 2016 to October 2016. Bone mineral density of lumbar vertebrae was measured by DXA(dual-energy X-ray absorptiometry (DXA). Abdominal CT scans were performed on the subjects, and a flat umbilical level CT film was selected at the post-processing workstation. The area of abdominal fat and paravertebral muscles was delineated. According to body mass index, the samples were divided into two groups: group A, 18.5 鈮，
