OBJECTIVE
To evaluate sedentary behaviour and physical activity levels in independently mobile older adults with and without dementia living in residential aged care.
METHODS
Sedentary behaviour and physical activity were measured in 37 residents of an aged care facility using an accelerometer worn during waking hours for five days.
RESULTS
Participants with valid accelerometer data (n = 28) spent 85% of the time sedentary, and 12% in low-intensity, 2% in light-intensity and 1% in moderate-to-vigorous-intensity physical activity. Over half of sedentary time was accumulated in bouts of greater than 30 minutes. Physical activity at any level of intensity was performed in bouts of less than 10 minutes.
CONCLUSION
Residents were highly sedentary and inactive. In particular, the short duration of each bout of activity amongst lengthy periods of sedentary behaviour was a substantial finding. The study suggests the need to develop innovative ways of breaking up sedentary behaviour in residential aged care.
目的
评估居住在老年护理机构中能够独立活动的患有和未患有痴呆症的老年人的久坐行为和身体活动水平。
方法
使用加速度计对一家老年护理机构的37名居民进行了测量，加速度计在清醒时间佩戴五天，以测量久坐行为和身体活动情况。
结果
拥有有效加速度计数据的参与者（n = 28）85%的时间处于久坐状态，12%的时间进行低强度活动，2%的时间进行轻度活动，1%的时间进行中等至剧烈强度的身体活动。超过一半的久坐时间是在超过30分钟的时间段内累积的。任何强度水平的身体活动每次持续时间均少于10分钟。
结论
居民久坐且缺乏运动。特别是，在长时间的久坐行为中，每次活动的持续时间较短是一个重要发现。该研究表明，需要开发创新方法来打破老年护理机构中的久坐行为。
