这项研究通过使用相同的加速度计指标，比较了瑞典和美国客观评估的身体活动水平和模式。比较了来自瑞典（2001-2002年，n = 1，172）和美国（2003-2004年，n = 2，925）的≥ 4天且每天佩戴加速计≥ 10小时的成年受访者的数据。按性别内的年龄和体重指数报告的结局包括每分钟加速度计计数以及不同强度的活动量和次数，即久坐、低强度、生活方式和中等或更高强度的体力活动。瑞典和美国男性的每分钟平均计数分别为375（95%置信区间（CI）：360，390）和377（95% CI：363，391），瑞典和美国女性分别为363（95% CI：347，379）和298（95% CI：289，307）。年龄较大的受访者和身体质量指数较高的人的活动水平较低。瑞典和美国男性每天花费36分钟（95% CI：34，38）和33分钟（95% CI：31，36），瑞典和美国女性每天花费32分钟（95% CI：29，34）和19分钟（95% CI：17，21）进行中等或更高强度的体力活动。老年瑞典人在中等或更高强度的活动中比老年美国受访者更活跃。然而，年轻的瑞典男性比年轻的美国男性有更多的久坐行为时间。这些结果为身体活动水平和模式的国际比较提供了一个框架，它们是对身体活动客观测量投资重要性的有力证据。
This study compares levels and patterns of objectively assessed physical activity in Sweden and the United States by using identical accelerometer metrics. Data of adult respondents with >= 4 days with >= 10 hours per day of accelerometer wear from Sweden (2001-2002, n = 1,172) and the United States (2003-2004, n = 2,925) were compared. Outcomes reported by age and body mass index within sex include accelerometer counts per minute and amounts and bouts of activity at different intensities, that is, sedentary, low, lifestyle, and moderate or higher intensity physical activity. The mean counts per minute were 375 (95% confidence interval (CI): 360, 390) and 377 (95% CI: 363, 391) for Swedish and US males, respectively, and 363 (95% CI: 347, 379) and 298 (95% CI: 289, 307) for Swedish and US females. Older respondents and those with higher body mass index had lower activity levels. Swedish and US males spent 36 (95% CI: 34, 38) and 33 (95% CI: 31, 36) minutes per day, and Swedish and US females spent 32 (95% CI: 29, 34) and 19 (95% CI: 17, 21) minutes per day in moderate or higher intensity physical activity. Older Swedes were more active in moderate or higher intensity activities than were older US respondents. However, younger Swedish males had more sedentary behavior time than did younger US males. These results provide a framework for international comparisons of physical activity levels and patterns, and they represent strong evidence for the importance of investment in objective measurement of physical activity.
