The aim of this study was to assess the energy expenditure of Belgian nursing home residents using indirect calorimetry and compare the energy expenditure with energy intake.
Indirect calorimetry was performed in nursing home residents to estimate their basal metabolism. The basal metabolism was multiplied by a physical activity level coefficient and energy expenditure that was related to thermogenesis (i.e., 10% of the total amount of energy ingested over 24 h) was added. In this way, we obtained the total energy expenditure of each nursing home resident. The nutritional intake of each resident was calculated using the precise food-weighing method over a 3-d period. The difference between energy expenditure and consumption was calculated for each patient and the mean of the difference in the population was calculated. These quantitative variables were compared by means of analysis of variance.
A total of 25 subjects were included in this study (88.1 ± 5.8 y; 84% women). The estimated mean basal metabolism was 1087.2 ± 163.2 kcal. The physical activity level was 1.29 ± 0.1 on average and the energy expenditure due to thermogenesis was 163.1 ± 28.9 kcal. Thus, the mean daily energy expenditure was 1575.2 ± 210.6 kcal, which was within the range of the actual calculated energy intake of the residents (1631.5 ± 289.3 kcal; P = 0.33).
The estimated energy intake of Belgian nursing home residents seems appropriate for their energy expenditure.
本研究旨在通过间接测热法评估比利时养老院居民的能量消耗，并将能量消耗与能量摄入进行比较。
对养老院居民进行间接测热法以估计其基础代谢率。将基础代谢率乘以体力活动水平系数，并添加与产热相关的能量消耗（即 24 小时内摄入的总能量的 10%）。通过这种方式，我们获得了每个养老院居民的总能量消耗。通过精确称重法在 3 天内计算每个居民的营养摄入量。为每个患者计算能量消耗与消耗之间的差异，并计算人群差异的平均值。使用方差分析比较这些定量变量。
本研究共纳入 25 名受试者（88.1 ± 5.8 岁；84%为女性）。估计的平均基础代谢率为 1087.2 ± 163.2 千卡。平均体力活动水平为 1.29 ± 0.1，产热相关的能量消耗为 163.1 ± 28.9 千卡。因此，平均每日能量消耗为 1575.2 ± 210.6 千卡，这在居民实际计算的能量摄入范围内（1631.5 ± 289.3 千卡；P=0.33）。
比利时养老院居民估计的能量摄入似乎适合他们的能量消耗。
