For community-living older people, the ability to estimate total daily energy expenditure (TDEE) with validated predictive equations based on anthropometry is limited. To our knowledge no studies exist for non-Caucasian populations OBJECTIVE: To design and validate an anthropometry-based equation to estimate TDEE using doubly-labelled water (DLW) as the criterion measure, and to assess the performance of three other published equations in community-living older people from rural and urban areas of Brazil, Chile, Guatemala, Senegal, Cuba, and Mexico METHODS: This cross-sectional study measured anthropometry and TDEE using DLW in 69 men and 43 women aged 60-89 years. TDEE was also estimated with an anthropometry-based equation derived from the sub-sample of Mexico (n = 38) and with three other published equations. Predictive accuracy of the equations was tested by an external validation procedure RESULTS: TDEE by DLW in the six country sample was 2411 ± 41 kcal/day (mean ± SE) in men and 1939 ± 51 kcal/day in women. The best new Mexican equation was TDEE, kcal/d = [223.4 + (27.9 × weight, kg) + (239.7 × sex)]; where sex: Man = 1 and Woman = 0; having high precision; R = 0.89, lowest RMSE = 149.2, and Cp value of 2.0. This new Mexican equation estimated TDEE accurately in the five country sample and at country level after correction for Guatemalan older men, while the published equations performed poorly CONCLUSIONS: The Mexican equation performed better that other published equations and is recommended to accurately estimate energy requirements for community-living older people in five Latin American and one African country.
对于社区居住的老年人来说，使用基于人体测量学的经过验证的预测方程来估计每日总能量消耗（TDEE）的能力有限。据我们所知，尚无针对非白种人群体的相关研究。目的：设计并验证一个基于人体测量学的方程，以双标水（DLW）作为标准测量方法来估计TDEE，并评估其他三个已发表方程在巴西、智利、危地马拉、塞内加尔、古巴和墨西哥城乡社区居住老年人中的性能。方法：这项横断面研究对69名男性和43名年龄在60 - 89岁的女性进行了人体测量，并使用DLW测量了TDEE。TDEE还通过从墨西哥子样本（n = 38）得出的基于人体测量学的方程以及其他三个已发表方程进行了估计。通过外部验证程序测试方程的预测准确性。结果：六个国家样本中男性通过DLW测得的TDEE为2411±41千卡/天（均值±标准误），女性为1939±51千卡/天。最佳的新墨西哥方程为：TDEE（千卡/天）= [223.4 +（27.9×体重，千克）+（239.7×性别）]；其中性别：男性 = 1，女性 = 0；具有高精度；R = 0.89，最低均方根误差（RMSE）= 149.2，Cp值为2.0。这个新墨西哥方程在五个国家样本以及对危地马拉老年男性进行校正后的国家层面上准确估计了TDEE，而其他已发表方程表现不佳。结论：墨西哥方程的表现优于其他已发表方程，建议用于准确估计五个拉丁美洲国家和一个非洲国家社区居住老年人的能量需求。
