Measurements of basal metabolic rate (BMR) were made in 528 children 2-16 y of age living in underprivileged areas of the city of Cali, Colombia (153 control and 186 undernourished boys, 93 control and 96 undernourished girls). The data are related to BMR calculated from the equations of Schofield and to estimates of the lean body mass (LBM). The ethnic composition of the subjects was 80% mestizo (mixed European and South Amerindian ancestry), 15% black, and 5% white. The data do not show any variations due to race in these subjects. The Schofield equations overestimate the BMR of boys by approximately 6% whereas the estimation of BMR in girls is not significantly different from measured values. More than 65% of the variation in BMR of both nutritionally normal and undernourished boys and girls is explained by variation in body size as estimated by the LBM.
对居住在哥伦比亚卡利市贫困地区的528名2至16岁儿童进行了基础代谢率（BMR）测量（153名对照男孩和186名营养不良男孩，93名对照女孩和96名营养不良女孩）。数据与根据斯科菲尔德方程计算的基础代谢率以及瘦体重（LBM）估计值相关。受试者的种族构成是80%梅斯蒂索人（欧洲和南美印第安人混血）、15%黑人以及5%白人。数据未显示这些受试者的基础代谢率因种族而有任何差异。斯科菲尔德方程对男孩基础代谢率的估计高估了约6%，而对女孩基础代谢率的估计与测量值无显著差异。营养正常和营养不良的男孩和女孩基础代谢率超过65%的变化可由瘦体重估计的体型变化来解释。
