血糖稳定的2型糖尿病患者的静息能量消耗

目的观察血糖控制良好的2型糖尿病患者静息能量消耗（REE）的特点。方法采用代谢车测量45例血糖稳定的2型糖尿病患者的REE，记录其一般情况、生化指标、Harris-Benedict和Owen公式计算基础能量消耗预测值，并进行比较分析。结果血糖稳定的2型糖尿病患者的静息能量消耗实测值与Harris-Benedict及Owen公式预测值比较差异无统计学意义（P〉0．05），相关分析显示REE与性别、年龄、体重、身高、体表面积、去脂组织显著相关（P〈0．05），与体重指数、脂肪组织、空腹血糖、餐后2h血糖、糖化血红蛋白、总胆固醇、三酰甘油、总蛋白、白蛋白、血红蛋白无相关性（P〉0．05），多元逐步回归分析显示去脂组织和年龄与REE关系最密切。结论血糖良好的2型糖尿病患者的REE并不增高，决定其REE的因素与健康个体相似，测定REE能更好地指导糖尿病的医学营养治疗。

Resting energy expenditure in patients with well controlled type 2 diabetes mellitus

Objective To investigate the features of resting energy expenditure (REE) in patients with well controlled type 2 diabetes mellitus (T2DM). Methods Totally 45 T2DM patients with stable blood glucose were enrolled. The general conditions, biochemical indicators, measurements of REE ( MREE), and basal energy expenditure (BEE) calculated with Harris-Benedict formula (HBEE) and Owen formula (OBEE) were recorded and compared. Results MREE had no significant difference with HBEE or OBEE in T2DM patients with stable blood glucose (P ＞ 0. 05). Correlation analysis showed that REE was significantly correlated with gender, age, body weight, body height, body surface area, and fat-free mass ( all P ＜ 0.05 ), but was not correlated with body mass index, fat mass, fasting plasma glucose, postprandial plasma glucose, haemoglobin Alc, total cholesterol, triglyceride, total protein, albumin, and haemoglobin (P ＞ 0. 05 ). Multiple regression analysis showed that fat free mass and age had the closest correlation with REE. Conclusions REE does not increase in T2DM patients with well controlled blood glucose. Factors that influence their REE are similar with healthy individuals. Determi nation of REE can provide useful information for the nutrition treatment of T2DM.
