摘要：The daily energy expenditure and physical activity index of institutionalized Japanese elderly women were measured. One hundred and thirteen Japanese elderly women (aged 79.5±7.0 y) who live in institutions for the elderly and receive meal services partici-pated voluntarily. A dietary survey, energy metabolic study, and time study were carried out over three consecutive days, and the basal metabolic rate (BMR) and energy expenditure by physical activity were measured. The intensity of daily physical activity was based on the physical activity index (PAT: total/basal energy expenditure), The mean BMR was 881±145 kcal/d (20.9±3.8 kcal/kg BW). The PAT in individuals ranged from 1.01 to 1.5 7, the mean value was 1.26±0.14, and 64% of the subjects examined showed a lower value than 1.3 of PAT. From these values, the mean total energy expenditure was calculated as 1, 112±231 kcal/d (26.2±5.2 kcal/kg BW).
