目的：探讨双能 X 线吸收技术(DEXA)在体脂测量方面的应用价值以及体脂分布与颈动脉粥样硬化之间的关系。方法使用 DEXA 测量78例2型糖尿病患者和79例正常健康人的体脂分布。与腰围诊断标准进行一致性检验。用 B 型超声测量颈总动脉及颈动脉窦部内膜中层厚度，并测量颈总动脉及颈动脉窦部所有动脉粥样硬化斑块的厚度，计算斑块积分。结果颈动脉内膜中层厚度(CIMT)及斑块积分在糖尿病中心性肥胖组与糖尿病非中心性肥胖组及对照组间比较差异有统计学意义；以 DEXA 方法测量体脂分布与腰围方法的一致性较好，判断中心性肥胖躯干脂肪比例切点为38.46%。结论评价中心性肥胖可以用 DEXA 测定体脂分布；体脂分布和糖尿病患者颈动脉粥样硬化之间关系密切。

Objective To study the value of dual-energy X-ray absorptiometry in the detection of body fat distribution and the relariongship between body fat distribution and the carotid atherosclerosis in type 2 diabetic mellitus(T2DM)patients.Methods Body fat distribution was measured by dual energy x-ray absorptiometry in 78 T2DM patients and 79 normal controls.The consistency between the body fat distribution and the standard waistline for abdominal obesity was verified.The carotid intima-media thickness was measured by B type ultrasound.The plaque in the cephalic artery and carotid sinus was also measured.The plaque index was calculated with the Crouse method. Results Carotid intima-media thickness and Crouse score were statistically differently among the subgroups. Reasonable consistence between the body fat distribution and the standard waistline for abdominal obesity was obtained.The cutoff point of trunk fat ratio in abdominal obesity was 38.46%.Conclusion Dual energy x-ray absorptiometry could be used to assess body fat distribution. Body fat distribution is closely related to the carotid atherosclerosis in T2DM patients.
