The purpose of this study was to compare REE between obese and nonobese children. Subjects were 24 obese (12 boys, 12 girls) and 45 normal weight (16 boys, 29 girls) Korean students aged 7–12y. REE was measured by indirect calorimetry(TrueOne 2400). REE were significantly higher in obese groups(boys 1448±211 kcal/day, girls 1291±132 kcal/day) than in nonobese groups(boys 1157±84 kcal/day, girls 1122±108 kcal/day). But, REE/weight of obese students(boys 27±2 kcal/day, girls 29±3 kcal/day) were significantly lower than that of nonobese students(boys 36±4 kcal/day, girls 31±3 kcal/day). And, there was no significant difference in REE/fat‐free mass(FFM) between obese and nonobese groups. FFM was also positively correlated with REE( r =0.84, p <0.001). These data explain that FFM is one of the most important factors which influence on REE. Therefore, to prevent the reduction of REE during weight loss, it is necessary to maintain or increase the percentage of FFM.
