摘要
目的 探讨慢性阻塞性肺病 (COPD)静息能量消耗 (REE)与营养状况的关系。方法 按体重指数 (BMI)从小到大依此将 3 3例COPD患者分为A、B、C三组 ,另设 2 0例健康者作对照组 (D组 ) ,运用间接测热法对上述 4组进行REE测定。结果 A、B、C、D组单位体重REE(REE/WT)分别是 ( 2 3 .8± 2 .8)、( 2 3 .4± 4.2 )、( 17.7± 2 .8)和 ( 2 0 .2± 1.7)kcal/kg ,A、B两组显著 >C、D组 ,C组 <A、B、D组 (P <0 .0 1) ,COPD组BMI与REE/WT呈显著负相关 (r =-0 .5 3 3 71,P <0 .0 1)。结论 COPD营养状况与基础能量代谢高度相关 ,COPD超高能量代谢的特点仅适用于营养不良及营养正常组 。
Objective To study the relationship between resting energy expenditure and nutritional status in patients with COPD.Methods Patients with COPD were divided into three groups A,B,C according to BMI from low to high, and control subject as D group. REE were measured in A, B, C, D groups by indirect calorimetry with metabolic cart.Results REE/WT of A, B, C, D were(23.8±2.8),(23.4±4.2) amd(17.7±2.8),(20.2±1.7)?kcal/kg,respectively,it showed that A, B groups were higher than C, D groups and C group was the lowest in all groups significantly( P <0.01). A significant negative correlation existed between BMI and REE/WT in patients with COPD.Conclusion The relative increase resting energy expenditure bears a close relationship to the nutritional status in patients with COPD. Non overweight COPD are possessed of the characteristic of hyper metabolism.
