目的探讨DEXA(dual-energy X-ray absorptiometry双能X线吸收法)测量体脂分布的价值及其与胰岛素抵抗(IR)的关系。方法测量2型糖尿病患者体脂分布,研究其脂肪分布规律,且与IR的关系。结果躯干脂肪比例诊断肥胖症的能力中等,诊断切点为>32%,可反映IR。结论 DEXA测量的体脂分布可评价内脏型肥胖。并可在一定程度上反映IR。
Objective To investigate the value of DEXA (dual-energy X-ray absorptiometry) measurement of body fat distribution and its relationship with insulin resistance (IR). Methods The body fat distribution in patients with type 2 diabetes mellitus was measured, the distribution of fat was studied, and the relationship with IR was also studied. Results Torso fat ratio was moderate in diagnosing obesity. The diagnostic cutoff point was> 32%, which could reflect IR. Conclusion Body fat distribution measured by DEXA can assess visceral obesity. And to some extent, reflect the IR.
