摘要

本研究目的在於比較分析中老年高血壓患者之不同休閒時間身體活動量對死亡風險之影響。本研究以衛生署「台灣地區中老年身心社會生活狀況長期追蹤調查」2003至2007年資料為分析依據，以2003年50歲以上中老年男女受試者做為樣本基礎資料來源，經篩選出高血壓患者計1753人，然後將受試者的平時休閒時間身體活動狀況分成高、中、低不同量之3組，並持續追蹤記錄受試者存活情形至2007年止。將所有資料登錄並以Cox正比例涉險迴歸模式分析，結果顯示只有高身體活動量組受試者之死亡風險顯著低於低身體活動量組（aHR為0.60,95% CI: 0.43-0.85）。在不同性別分析上，女性較高身體活動量組之受試者亦有顯著較低之死亡風險（aHR為 0.42, 95% CI: 0.21-0.84），而男性受試者之各組則皆不顯著。本研究發現從事較高休閒時間身體活動量之高血壓患者顯著影響中老年人之死亡率，特別是每週休閒時間身體活動6次以上，且每次身體活動持續30分鐘以上，有助於降低死亡風險。且依不同性別而言，女性患者如從事較高休閒時間身體活動量能顯著降低死亡風險，但男性患者則無明顯差異。

In this study, the association between leisure-time physical activity and the risk of death was examined in middle-aged and elderly adult patients with hypertension. Analyses were conducted using nationally representative data from the 2003 and 2007 Health and Living Status of the Elderly Survey in Taiwan. A screening test was used to identify 1753 patients with hypertension from a cohort of 5377 participants aged 50 and older in the baseline year (2003). The frequency and duration of physical activity were reported at the baseline according to 3 categories of activity status: light, medium, and high. After a 4-year follow-up, Cox’s proportional hazards regression models were used to assess the association between the dose response of physical activity and risk of death. Compared with the participants who performed light physical activity, those engaging in a high status of physical activity were at a significantly lower risk of mortality (multivariable-adjusted hazard ratio [aHR] = 0.60, 95% CI = 0.43-0.85). A similar reduction was observed in women who participated (aHR = 0.42, 95% CI = 0.21-0.84) but not in the men. In general, the results of this study showed that engaging in regular leisure-time physical activity as a form of exercise (minimum of 6 sessions/week, 30 min/session) reduces the risk of mortality.
