摘要

身體活動為促進成年人健康、降低疾病風險的重要因子之一。但目前以台灣人為族群的研究中，尚未清楚達到閒暇時間身體活動建議量與死亡風險的關聯，此外，在未達到建議量的族群中，從事家事活動對降低死亡風險的影響也未知。據此，本研究目的為探討台灣中老年人從事符合建議量的閒暇時間身體活動與否，對全因死亡風險的影響，此外也針對做不足身體活動量的族群，探討其參與家事活動與否，在全因死亡風險上的差異。研究方法採用前瞻性世代研究設計，樣本來源為台灣中老年身心社會生活狀況長期追蹤調查 (TLSA) 2003年的資料，依據身體活動官方建議量、身體活動範疇進行樣本分組，並以2015年TLSA存活資料收集全因死亡率，最後以存活分析中的Cox比例風險模型檢驗不同身體活動分組下的全因死亡風險。結果顯示，在閒暇身體活動範疇中，有達到建議活動量組，相較未達到建議量組，顯著降低全因死亡風險 (HR=0.83, 95% CI: 0.72-0.96)；而在未達身體活動建議量的族群中，有從事家事活動組，相較沒從事家事活動組，也顯著降低全因死亡風險 (HR=0.82, 95% CI: 0.73-0.93)。此研究證實做符合建議量的閒暇時間身體活動可以降低全因死亡風險，而若做不足量，也能透過做家事來降低風險。此研究的發現具有實務應用價值，提供人們安排健康生活的指引。

Physical activity (PA) is one of the essential factors that help adults improve health and reduce the risk of diseases. However, the relationship between meeting leisure-time physical activity (LTPA) recommendations and all-cause mortality in the Taiwanese population is less clear. And it is still unknown whether household physical activity (HPA) may lead to different results among people with insufficient LTPA. This study aims to investigate the effect of sufficient LTPA on all-cause mortality in Taiwanese middle-aged and older adults, and the effect of HPA in those with insufficient LTPA. The study is a prospective cohort study design, which of subjects come from the 2003 Taiwan Longitudinal Study in Aging (TLSA) survey. PA pattern will be divided into specific groups based on the official recommendations and domains. The mortality information is taken from the 2015 TLSA data. Cox proportional hazards regression would be conducted for survival analyses. The results show that engaging in sufficient LTPA would significantly lower the risk of all-cause mortality (HR=0.83, 95% CI: 0.72-0.96). For those with insufficient LTPA, doing HPA also significantly reduced the risk (HR=0.82, 95% CI: 0.73-0.93). This study confirmed that sufficient LTPA would lower the risk of all-cause mortality. And if sufficient LTPA can not be done, doing HPA also has a positive effect on lowering mortality. These findings have practical importance and provide people guidance to arrange a healthy lifestyle.
