Emerging research demonstrates that light-intensity physical activity is favorably associated with numerous health outcomes among the general population, even independent of high-intensity physical activity.
To examine the association between accelerometer-assessed light-intensity physical activity and mortality in a national sample of American adults with mobility limitations.
Data from the 2003-2006 National Health and Nutrition Examination Survey were utilized. Participants were followed through 2011. Based on self-report, analyzed participants included those with mobility limitations (N = 1369). Light-intensity physical activity was assessed via waist-mounted accelerometry.
For the sample, 108,010 person-months occurred with an all-cause mortality rate of 2.07 per 1000 person-months. After adjustments, for every 60 min/day increase in light-intensity physical activity, participants with mobility limitations had a 14% reduced risk of all-cause mortality (HR = 0.86; 95% CI: 0.75-0.98; P = 0.03).
These findings underscore the importance of promoting light-intensity physical activity to those with mobility limitations.
新的研究表明，即使不考虑高强度的体育活动，低强度的身体活动也与普通人群的许多健康结果呈正相关。
在一个有行动障碍的美国成年人的全国样本中，研究计步器评估的低强度身体活动与死亡率之间的关系。
利用了 2003-2006 年全国健康与营养调查的数据。参与者随访至 2011 年。根据自我报告，分析参与者包括有行动障碍的人（N=1369）。通过佩戴在腰部的加速度计评估低强度身体活动。
对于该样本，共发生了 108010 人月，全因死亡率为每 1000 人月 2.07 人。调整后，低强度身体活动每天增加 60 分钟，有行动障碍的参与者全因死亡率降低 14%（HR=0.86；95%CI：0.75-0.98；P=0.03）。
这些发现强调了向有行动障碍的人推广低强度身体活动的重要性。
