本研究的目的是评估MedGem （TM）设备测量儿童静息代谢率（RMR）的有效性和可靠性。研究对象包括59名儿童（29名男孩，30名女孩，平均年龄11.0±0.2岁）。受试者在1个测试阶段进行4次RMR测试，其中2次为Douglas bag测试，2次为MedGem测试，测试顺序随机平衡。道格拉斯袋和MedGem系统的耗氧量（分别为209 +/- 5和213 +/- 5 mL/min， P = 0.106, r = 0.911，平均+/-标准差绝对差3.72 +/- 17.40 mL/min）和RMR（1460 +/- 39和1477 +/- 35 kcal/d， P = 0.286, r = 0.909，平均+/-标准差绝对差17.4 +/- 124 kcal/d）无显著差异。耗氧量和RMR估计的标准误差分别为17.4 mL/min和124 kcal/d。总之，这些数据表明，MedGem是一种可靠有效的测量儿童耗氧量和RMR的系统。
The purpose of this study was to assess the validity and reliability of the MedGem (TM) device to measure resting metabolic rate (RMR) in children. Subjects included 59 children (29 boys, 30 girls; mean age, 11.0 +/- 0.2 y). Subjects were given 4 RMR tests during I test session, cconsisting of 2 Douglas bag and 2 MedGem tests, in random counterbalanced order. No significant differences were found between Douglas bag and MedGem systems for oxygen consumption (209 +/- 5 and 213 +/- 5 mL/min, respectively, P = 0.106, r = 0.911, mean +/- standard deviation absolute difference 3.72 +/- 17.40 mL/min) or RMR (1460 +/- 39 and 1477 +/- 35 kcal/d, P = 0.286, r = 0.909, mean +/- standard deviation absolute difference 17.4 +/- 124 kcal/d). Standard error of estimates for oxygen consumption and RMR were 17.4 mL/min and 124 kcal/d, respectively. In conclusion, these data indicate that the MedGem is a reliable and valid system for measuring oxygen consumption and RMR in children.
