摘要

肥胖在全世界學童人口中持續的增加，儼然已成為一嚴重的公共衛生問題。本研究目的在探討肥胖國中生接受減重數位學習系統介入前後對體重控制知識、身體心像、自尊、自我效能，以及肥胖生理指標及體適能之成效影響，及對減重數位學習系統之滿意度。研究採類實驗研究法，單組前後測設計，以立意取樣於台北市某二所國中，篩選出37位BMI≥25kg/ m²、有意願加入減重社團的學生為研究對象。減重數位學習系統包括知識課程十四週，以課堂講授方式進行，課後輔以運動、個別諮商及獎勵，學生於家中利用數位學習系統進行減重知識瀏覽及飲食運動紀錄。研究對象在課程介入前後分別以問卷評量體重控制知識、身體心像、自尊及自我效能之改變，以及肥胖生理指標、體適能測量減重成效；課程結束後以減重數位學習系統滿意度問卷進一步瞭解學生對課程及減重數位學習系統之滿意度。研究結果顯示：肥胖國中生之體重控制知識、身體心像、自尊及體重控制自覺自我效能在減重數位學習系統介入後有顯著提升（p<0.05）。減重成效在肥胖生理指標方面，BMI、腰圍、三頭肌皮脂厚度有顯著成效（p<0.05）；在體適能方面，一分鐘屈膝仰臥起坐（肌力及肌耐力）、三分鐘登階（心肺耐力）、立定跳遠（瞬發力）有顯著進步（p<0.05）。國中生對減重數位學習系統的實施大都滿意與肯定，且能增進團體歸屬感及同儕情誼，教師反應本系統可提供廣大豐富的資料庫來源，有利於教案設計及課程實施之參考。本研究結果證實以減重數位學習系統輔助校園管理肥胖問題乃可行作法，可提供學校教師及醫護人員規劃與執行學生減重課程之參考，進一步幫助肥胖國中生在多元便捷的學習環境中有效控制體重，並擁有較佳的身體適能，促進身心健康。

Obesity in schoolchildren is continuing to rise at an alarming rate and becomes an important public health problem worldwide. Therefore, the aims of this study were 1）to compare the knowledge score, body image score, self-esteem score and self-efficacy score differences between pre-implementing and post-implementing of weight-loss e-learning program （WEP） for obese junior high school students 2）to compare the obese index and physical fitness differences between pre-implementing and post-implementing of WEP for obese junior high school students and 3) to understand the satisfaction with the WEP by obese junior high school students.

The design was quasi-experimental using purposive samples from two junior high schools in Taipei. Participants were selected if their body mass indexes（BMI） were equal or greater than 25 kg/m2 and if they were willing to participate in this study. A fourteen-week WEP include regular classes, excersice programs, individual consultation and reward policy. Participants can use the WEP to get weight loss information and record daily calorie and daily amounts of activity at home. Instruments including knowledge questionnaire, body image questionnaire, self-esteem questionnaire and satisfaction questionnaire were used to collect data.

After implementing the WEP, the knowledge scores, body image score, self-esteem score and self-efficacy score were all improved significantly（p<0.05）. The physical measures（BMI, Waist circumference, triceps skinfold）, and fitness levels（One minute bent-leg curl-ups, Tree Minutes Step Test, Standing Long Jump Test）were all improved significantly（p<0.05）.Overall, children felt satisfied with theWEP.The findings can not only serve as valuable reference for schoolteachers to develop effective weight-loss program for obese children but also assist those children to control their weights and to promote their health in an effective environment.
