BACKGROUND
The objective of the study is to investigate the effects of reallocating time spent engaging in sedentary behavior (SB) and physical activity on the risk of mortality.
METHODS
In all, 332 older adult low-income and low-education populations participated in the study. At the end of the study, 273 of the participants were alive and 59 had died. Time spent undertaking moderate to vigorous physical activity (MVPA) and SB was assessed using the international physical activity questionnaire. The Cox proportional hazards regression model was used.
RESULTS
The replacement of time spent engaging in SB with MVPA reduced the risk of mortality from all causes in the older adults, resulting in reductions in mortality risk of between 10% and 46%.
CONCLUSION
A reduction in the risk of mortality in older adults was observed when time spent in SB was replaced with the same amount of time in MVPA for all times tested.
背景
本研究的目的是调查重新分配久坐行为（SB）和体育活动所花费的时间对死亡风险的影响。
方法
共有332名低收入、低教育水平的老年人群参与了本研究。研究结束时，273名参与者存活，59人死亡。使用国际体力活动问卷评估进行中度至剧烈体育活动（MVPA）和SB所花费的时间。采用Cox比例风险回归模型。
结果
用MVPA取代SB所花费的时间可降低老年人各种原因导致的死亡风险，死亡率风险降低10%至46%。
结论
在所有测试时间段内，当用相同时间的MVPA取代SB所花费的时间时，观察到老年人的死亡风险降低。
