目的 比较腹膜透析(peritoneal dialysis，PD)患者和血液透析(hemodialysis，HD)患者的静息能量消耗(resting energy expenditure,REE)的差异。 方法 选取北京市2家三级医院临床稳定的105例PD和35例HD患者，进行REE测定。 结果 本研究纳入患者的平均年龄(52.5±11.9)岁，平均体质量(68.6±15.1)kg，其中男性86例(57.7%)，糖尿病61例(43.6%)。HD患者和PD患者REE水平没有显著性差异(r=1.731，P=0.086)。HD和PD患者的REE均与身高(r=0.399、0.574， P=0.018、＜0.001)、体质量(r=0.756、0.730，均P＜0.001)、性别(男性：r=0.481、0.582，P=0.003、 ＜0.001)、握力(r=0.584、0.551，P＜0.001)和瘦体质量(r=0.674、0.677，均P＜0.001)呈正相关，与年龄(r=-0.432、-0.254，P=0.010、0.009)、透析龄(r=-0.356、-0.289，P=0.036、0.003)和透析充分性(Kt/V)(r=-0.786、-0.326，P＜0.001、0.002)呈负相关。 结论 年龄、性别、体质量和是否糖尿病相当的HD和PD患者，REE水平无显著差异。
Objective We aimed to compare the resting energy expenditure (REE) between peritoneal dialysis (PD) patients and hemodialysis (HD) patients. Methods This cross-sectional study enrolled 105 PD patients and 35 HD patients who were clinically stable from two tertiary hospitals in Beijing. Their REE was measured by indirect calorimetry. Results The mean age of the patients was 52.5±11.9 years old, and the body weight was 68.6±15.1kg, 57.7% being man and 43.6% having diabetes. The REE was 1432.6±339.4 kcal in HD patients and was 1334.6±271.8 kcal in PD patients, without significant difference between PD and HD patients (P=0.086). REE was positively correlated with height (r=0.399/0.574, P=0.018/＜0.001), weight (r=0.756/0.730, P＜0.001), male (r=0.481/0.582, P=0.003/＜0.001), grip strength (r=0.584/0.551, P＜0.001) and lean body mass (r=0.674/0.677, P＜0.001), negatively correlated with age (r=-0.432/-0.254, P=0.010/0.009), dialysis age (r=-0.356/-0.289, P=0.036/0.003) and urea clearance (Kt/V) (r=-0.786/-0.326, P＜0.001/0.002) in both HD and PD patients. Conclusions There was no significant difference in REE level between HD and PD patients.
