Resting metabolic rate in obese and nonobese Chinese Singaporean boys aged 13–15 y

摘要: Background: Previous studies investigating the hypothesis that a low resting metabolic rate (RMR) is cause of obesity yielded discrepant findings. Two explanations for these findings are use imprecise methods to determine and failure control differences in fat mass (FM) fat-free (FFM) when comparing RMR values. Objective: This study tested lower obese than nonobese boys (with precise quantify body fatness with adjustment both FM FFM). Design: Forty Chinese Singaporean aged 12.8-15.1 y were recruited. Boys classified as (n = 20) or on basis their adiposity index (ratio FFM: >0.60 obese, <0.40 nonobese) determined by dual-energy X-ray absorptiometry. was using indirect calorimetry. values compared linear (analysis covariance) log-linear covariance log-transformed data) regression FFM. Results: Age, height, FFM did not differ significantly between groups. Body 13 kg greater 16 (P <0.001). After FM, Conclusion: When composition appropriately controlled for, does boys.
