背景：体育活动（PA）在肥胖中起着重要作用。一种新的加速度计已经开发出来，用来评估总能量消耗和PA。目的：研究PA与日本男性和女性超重和肥胖的关系，使用单轴加速度计进行了一项大型横断面研究。设计、环境和参与者：日本18-84岁人群为基础的横断面研究。从1999年到2000年，研究人员测量了400名日本男性和388名女性志愿者的身高、体重和PA。结果测量为超重和肥胖，定义为体重指数≥25kg /m2。测量1至4周的PA，然后将其分为三个活动水平，分别定义为轻度，中度和剧烈PA。结果：超重和肥胖患病率为22.3%。在超重和肥胖人群中，每天进行中等强度和高强度运动的步数和时间较低。在轻度PA中花费的时间没有差异。处于中度和剧烈PA的第4和第5分位数的个体显示出明显较低的体重指数。当使用逻辑回归估计的超重和肥胖的奇比（or）作为效应衡量指标时，超重和肥胖与剧烈PA呈负相关（or =0.91）。结论：这些结果表明，超重和肥胖个体有较低的步频和花费较少的时间进行中度到高强度的运动。参与剧烈运动是超重和肥胖的重要预测因素。
CONTEXT:Physical activity (PA) plays an important role in obesity. A new accelerometer has been developed to assess total energy expenditure as well as PA.OBJECTIVE:To investigate the association of PA with overweight and obesity in Japanese men and women, a large cross-sectional study was performed using a single-axis accelerometer.DESIGN, SETTING AND PARTICIPANTS:Population-based cross-sectional study of Japanese 18–84 y of age. Height, body weight and PA were measured in 400 male and 388 female Japanese volunteers from 1999 to 2000. The outcome measurements were overweight and obesity, which are defined as a body mass index ≥25 kg/m2. PA was measured for 1 to 4 weeks and was then categorized into three activity levels, which were defined as light, moderate and vigorous PA.RESULTS:Prevalence of overweight and obesity was 22.3%. Number of steps and time spent in moderate and vigorous PA per day were lower in overweight and obese individuals. No difference was found in time spent in light PA. Individuals who are in the 4th and 5th quintile of moderate and vigorous PA showed a significantly lower body mass index. When odd ratios (ORs) of overweight and obesity estimated by logistic regression were used as effect measures, overweight and obesity were negatively associated with vigorous PA (ORs=0.91).CONCLUSION:These results indicate that overweight and obese individuals have a lower step rate and are spending less time for moderate to vigorous PA. Participation in vigorous PA is an important predictor of overweight and obesity.
