本研究的目的是调查自由生活的日本成年女性的体重指数（如BMI、无脂肪质量指数（FFMI，FFM/身高（2））、脂肪质量指数（FMI，FM/身高（2））和体脂百分比（%BF））与体力活动（通过双标记水（DLW）法和加速度计评估）之间的关系。我们在100名年龄从31岁到69岁的女性受试者中进行了一项横断面研究。受试者按BMI、FFMI、FMI和%BF的四分位数分类。每日步行步数和轻度至剧烈体力活动的持续时间通过加速度计同时评估，持续时间与DLW实验相同。只有身体活动相关的能量消耗（PAEE）/FFM和PAEE/体重（BW）在BMI的最高四分位数下降。在FMI和%BF的最高四分位数中，体力活动水平、PAEE/FFM和PAEE/BW降低，而在FFMI的四分位数中它们没有差异。每日步行步数和中等强度和高强度体力活动的持续时间在FMI和%BF的最高四分位数中减少或倾向于减少，但在FFMI和BMI的四分位数中没有差异。这些结果清楚地表明，具有较高脂肪沉积的日本成年女性明显具有低水平的身体活动，通过DLW方法和加速度计评估，但具有较大BMI的那些具有较低的PAEE/FFM和PAEE/BW。我们的数据表明，肥胖和日常体力活动之间的关系，应讨论不仅使用BMI，但FMI或%BF。
The objective of the present study was to investigate the relationship between the indices of body size such as BMI, fat-free mass index (FFMI, FFM/height(2)), fat mass index (FMI, FM/height(2)), and body fat percentage (%BF), and physical activities assessed by the doubly-labelled water (DLW) method and an accelerometer in free-living Japanese adult women. We conducted a cross-sectional study in 100 female subjects ranging in age from 31 to 69 years. Subjects were classified in quartiles of BMI, FFMI, FMI and %BF. Daily walking steps and the duration of light to vigorous physical activity were simultaneously assessed by an accelerometer for the same period as the DLW experiment. Only physical activity-related energy expenditure (PAEE)/FFM and PAEE/body weight (BW) decreased in the highest quartile of BMI. Physical activity level, PAEE/FFM and PAEE/BW decreased in the highest quartile of FMI and %BF, whereas they were not different among quartiles of FFMI. Daily walking steps and the duration of moderate-and vigorous-intensity physical activities decreased or tended to decrease in the highest quartile of FMI and %BF, but did not differ among quartiles of FFMI and BMI. These results clearly showed that Japanese adult women with higher fat deposition obviously had a low level of physical activities assessed by both the DLW method and accelerometry, but those with larger BMI had lower PAEE/FFM and PAEE/BW only. Our data suggest that the relationship between obesity and daily physical activities should be discussed using not only BMI but also FMI or %BF.
