【摘要】：目的探讨腰椎骨质密度(BMD)与年龄、性别、体质参数及腹部皮下脂肪(SAT)、内脏脂肪(VAT)的关系。方法纳入健康志愿者或慢性腰腿痛患者111人(男56人,女55人),测量受检者身高、体质量及腰围,计算体质指数(BMI);采用定量CT(QCT)行腹部扫描,测量L3的BMD及相应层面腹部SAT与VAT含量。将男性与女性分别分为骨质疏松组、骨量减少组和骨量正常组,分别比较3组间年龄、性别、身高、体质量、BMI、腰围、SAT和VAT的差异,对BMD与存在显著性差异的指标进行相关性分析。结果 3组男性间除年龄的差异有统计学意义(P0.05)外,身高、体质量、BMI、腰围、SAT及VAT的差异均无统计学意义(P均0.05);男性BMD与年龄呈负相关(r=-0.680,P0.05)。3组女性年龄、腰围及VAT的差异有统计学意义(P均0.05),身高、体质量、BMI、SAT差异均无统计学意义(P均0.05);女性BMD与年龄、腰围、VAT均呈负相关(r=-0.849、-0.412、-0.501,P均0.05)。结论男、女性腰椎BMD与年龄均呈明显负相关,与身高、体质量、BMI无明显相关性;男性腰椎BMD与腰围、SAT与VAT均无明显相关性,但女性腰椎BMD与腰围及VAT关系密切。
[Abstract]:Objective to investigate the relationship between lumbar bone density (BMD) and age, sex, physique parameters and (VAT) of (SAT), visceral fat in abdominal subcutaneous fat. Methods A total of 111 healthy volunteers or patients with chronic low back leg pain (56 males and 55 females) were enrolled. Height, body mass and waist circumference were measured. Body mass index (BMI);) was calculated. The BMD of L 3 and the contents of SAT and VAT in abdomen were measured by quantitative CT (QCT). Male and female were divided into three groups: osteoporosis group, osteopenia group and normal bone mass group. The differences of age, sex, height, body mass, BMI, waist circumference, SAT and VAT were compared among the three groups. The correlation between BMD and the indexes with significant difference was analyzed. Results there was no significant difference in height, body weight, BMI, waist circumference, SAT and VAT between the three groups except age (P0.05). There was a negative correlation between male BMD and age (r = -0.680). There were significant differences in age, waist circumference and VAT among the three groups (P 0.05), but there was no significant difference in height, body weight and BMI,SAT among the three groups (P 0.05). There was a negative correlation between BMD and age, waist circumference and VAT (r = 0.849). Conclusion Lumbar BMD was negatively correlated with age, but not with height, body weight and BMI, while lumbar BMD was not correlated with waist circumference, SAT and VAT, but female lumbar BMD was closely related with waist circumference and VAT.
