To measure total energy expenditure (TEE) for normal healthy Japanese by the doubly labelled water (DLW), and to compare the physical activity level (PAL) among categories classified by the categories used in daily reference intake (DRI), Japan and the International Physical Activity Questionnaire (IPAQ).
A total of 150 healthy Japanese men and women aged 20- to 59-year-old living in four districts of Japan. TEE was measured by the DLW method, and the PAL was calculated from TEE divided by basal metabolic rate. Simultaneously with TEE measurement, the PAL was assessed employing the categories used in DRI, Japan and IPAQ.
The average TEE and PAL were 10.78+/-1.67 MJ/day and 1.72+/-0.22 for males and 8.37+/-1.30 MJ/day and 1.72+/-0.27 for females, respectively. The subjects in the highly active categories assessed by both DRI and IPAQ showed significantly higher PAL compared with less active categories. However, PALs among light and moderate categories by DRI, and insufficient and sufficiently active by IPAQ were not significantly different.
In developed countries, highly active subjects could be assessed by a simple questionnaire. However, the questionnaire should be improved to clarify the sedentary to moderately active subjects by assessing carefully very light to moderate physical activity.
采用双标水法（DLW）测量正常健康日本人的总能量消耗（TEE），并比较按日本每日参考摄入量（DRI）、国际体力活动问卷（IPAQ）所使用的类别划分的不同类别之间的体力活动水平（PAL）。
共有150名年龄在20至59岁之间、居住在日本四个地区的健康日本男性和女性。通过双标水法测量TEE，并根据TEE除以基础代谢率计算PAL。在测量TEE的同时，采用DRI、日本和IPAQ所使用的类别评估PAL。
男性的平均TEE和PAL分别为10.78±1.67兆焦/天和1.72±0.22，女性分别为8.37±1.30兆焦/天和1.72±0.27。经DRI和IPAQ评估为高活动类别的受试者与低活动类别的受试者相比，PAL显著更高。然而，DRI划分的轻度和中度类别之间以及IPAQ划分的不充分活动和充分活动之间的PAL没有显著差异。
在发达国家，高活动水平的受试者可以通过简单的问卷进行评估。然而，问卷应加以改进，通过仔细评估极轻度至中度的体力活动来明确久坐至中度活动的受试者。
