【摘要】：目的評價絕經(jīng)后女性腹部脂肪和椎旁肌肉與骨密度的相關(guān)性。方法選取2016年4月至2016年10月就診于我院的絕經(jīng)后女性75例,年齡45~83(62.2±9.1)歲,應(yīng)用DXA(dual-energy X-ray absorptiometry,DXA)測量腰椎骨密度,再對受檢者行腹部CT掃描,并在后處理工作站選定平臍水平的CT片,勾畫出腹部脂肪和椎旁肌肉的面積。為了進(jìn)一步分析,將樣本根據(jù)體重指數(shù)分為2組,A組18.5≤BMI24,B組BMI≥24。結(jié)果腰椎骨密度與體重指數(shù)、腹部皮下脂肪、腹部內(nèi)臟脂肪、腹部總脂肪、腰大肌及豎脊肌均呈正相關(guān)(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)。通過將BMI(body Mass Index)分為2組后得到結(jié)果:A組骨密度主要與腰大肌和豎脊肌呈正相關(guān)(r=0.479,P=0.011;r=0.424,P=0.028),B組骨密度主要與內(nèi)臟脂肪和總脂肪呈正相關(guān)(r=0.318,P=0.028;r=0.339,P=0.019)。結(jié)論目前研究結(jié)果表明,對于絕經(jīng)后女性而言,腹部脂肪和椎旁肌肉對骨密度具有保護(hù)作用,適當(dāng)?shù)捏w育鍛煉和保持正常的體重更有利于預(yù)防骨質(zhì)疏松癥。
[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 鹵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，
