背 景：臺灣老人是代謝症候群的高發生率族群，然而較少研究合併採用飲食與運動的措施來 處理鄉村地區65 歲以上老人的代謝症候群。 目 的：探討飲食和運動介入對社區代謝症候群老年居民的成效。 方 法：本研究採類實驗研究設計，研究對象為65 歲（含）以上且罹患代謝症候群。測量變項， 包括血壓、腰圍、臀圍、身體質量指數、空腹血糖、膽固醇、三酸甘油酯和人口學基 本屬性等。研究對象分成飲食運動組（DE, n = 163）與非飲食運動組（NDE, n = 138）。 DE組給與指導手冊包含飲食介入，教導每日需攝取五蔬果，運動介入以每週運動三 次，每次至少三十分鐘，且自我檢查心跳上升至90-150跳／分，NDE組的飲食和運動 如常。經過三個月介入後再檢視所測得數據。 結 果：研究結果發現，與NDE組相比較下，DE組顯著的有較低的血壓值、腰圍、臀圍、身 體質量指數、空腹血糖、膽固醇、三酸甘油酯（所有p < .001）。 結 論／ 實務應用：研究結果，飲食和運動介入計劃對社區代謝症候群老年居民是有效性策略，為促進居 民健康，社區護理人員應衛教社區民眾飲食和運動相關的策略。

Background: The prevalence of metabolic syndrome is high among older adults in Taiwan.However, fewstudies have studied the effect of a combined diet and exercise program on managing metabolic syndrome (MetS) in individuals 65 years and older and living in Taiwan’s rural areas. Purpose: This study tests the effectiveness of a diet and exercise program on the MetS biomarkers in older community residents with MetS. Methods: This study used a quasiexperimental study design. All participantswere 65 years and older andwere diagnosed with MetS. The outcome variables included biomarkers (blood pressure, waist circumference, hip circumference, body mass index, blood sugar, cholesterol, and triglycerides) and demographic characteristics. The participants were distributed into a diet-and-exercise group (n = 163) and a nondiet-and-nonexercise group (n = 138). The outcome variables were examined 3 months after the start of the intervention program. Results: The participants in the diet-and-exercise group had lower values than the nondiet-and-nonexercise group for blood pressure, waist circumference, hip circumference, body mass index, blood sugar, cholesterol, and triglyceride (all ps G .001). Conclusions/Implications for Practice: The diet and exercise program is an effective intervention for treating older individuals with MetS. Clear and concise information concerning the effects of diet and exercise in promoting the health of older residentswith MetS is helpful to improve the health of the older adults in Taiwan.
