摘要

本研究評估依據社會認知理論及行為改變策略發展之成人降低脂肪攝取營養教育課程－「減脂之旅」之成效，課程包含八個單元，每個單元50分鐘，進行方式為每週一個單元。介入研究在台北市兩處職場進行，共有51名員工參加，於課程進行前、後一週及結束後一個月實施包括問卷及身體檢查等的評量。研究結果發現：降低脂肪攝取營養教育課程－減脂之旅實施後，受試者之降低脂肪攝取營養知識、態度、飲食行為及自我效能量表得分上有顯著增進，且對於不同性別、年齡、教育程度、營養訊息關心度者均有成效。受試者之低密度脂蛋白膽固醇(LDL-C)、脂肪攝取佔熱量百分比均有顯著降低，但在體重、身體質量指數(BMI)、血壓、血清總膽固醇(TC)、三酸甘油酯(TG)、高密度脂蛋白膽固醇(HDL-C)等的改變並不顯著。降低脂肪攝取營養知識與營養態度是飲食行為之主要預測變項，背景變項對於降低脂肪攝取飲食行為之預測及解釋力較弱。根據研究結果推論，藉由減脂之旅課程確實可以提升成年人之脂肪攝取之營養知識、態度及自我效能，進而改變其飲食行為，降低脂肪攝取。

The purpose of this study was to develop an adult fat intake reduction education program and assess its effectiveness. The program, Journey of Dietary Fat Reduction, was designed based on social cognitive theory and strategies of behavioral change. It contains eight 50-min sessions, one session given per week, with an intervention period of 8 weeks. The subjects were 51 employees of two companies In Taipei City. The effect of intervention was assessed by a questionnaire and physical examination which were administered a week before (pre-test), a week after (post-test), and 1 month after (follow-up test) the intervention. Results indicate that the nutrition education program significantly (p ＜ 0.05) improved the subjects’ dietary fat reduction nutrition knowledge, attitude, behavior, and self-efficacy regardless of sex, age, educational level, cholesterol decreased after the intervention, but not weight, body mass index, blood pressure, plasma total cholesterol decreased after the intervention, but not weight, body mass index, blood pressure, plasma total cholesterol, high density lipoprotein-cholesterol, or triglyceride. Dietary fat reduction nutrition knowledge and attitude predicted behavior better than did demographic variables (sex, age, or education level). The results indicate that the nutrition education program, Journey of Dietary Fat Reduction, can successfully enhance an adult’s dietary fat reduction nutrition knowledge, attitude, and self-efficacy and thereafter improve dietary behavior.
