Since the World Health Organization suggested predictive equations for basal metabolic rate (BMR) in 1985 there has been great interest in their validity in different populations worldwide. It has been shown that these equations overestimate BMR in some populations, particularly the ones living in the tropics. There is limited new information on BMR in segments of the Brazilian population. Therefore, the aim of the present study was to compare measured with estimated BMR using some published predictive equations in 50 college students from Rio de Janeiro, Brasil. BMR was measured by indirect calorimetry and the predictive equations used were the ones published by: FAO/WHO/UNU (1985); Harris & Benedict (1919), and Henry & Rees (1991). Estimated BMRs were significantly greater than measured BMR (p < 0.05). Overestimation was greatest with the equation published by Harris & Benedict (18.9%) followed by the ones by FAO/WHO/UNU (12.5%) and Henry & Rees (7.2%). Body composition did not correlate with the overestimation of BMR. More data are necessary so that appropriate predictive equations can be developed for the Brazilian population.
自1985年世界卫生组织提出基础代谢率（BMR）的预测方程以来，人们对其在全球不同人群中的有效性产生了浓厚兴趣。研究表明，这些方程在某些人群中高估了基础代谢率，特别是生活在热带地区的人群。关于巴西部分人群基础代谢率的新信息有限。因此，本研究的目的是使用一些已发表的预测方程，比较巴西里约热内卢50名大学生的实测基础代谢率和估算基础代谢率。基础代谢率通过间接测热法测量，使用的预测方程来自：粮农组织/世界卫生组织/联合国大学（1985年）；哈里斯和本尼迪克特（1919年），以及亨利和里斯（1991年）。估算的基础代谢率显著高于实测基础代谢率（p < 0.05）。哈里斯和本尼迪克特发表的方程高估程度最大（18.9%），其次是粮农组织/世界卫生组织/联合国大学的方程（12.5%）和亨利与里斯的方程（7.2%）。身体成分与基础代谢率的高估无关。需要更多数据，以便为巴西人群开发合适的预测方程。
