根據教育部資料顯示，國小學童過重及肥胖的比率已達 25%。本研究目的是欲探討營養教育的介入對體重過重及肥胖學童在營養知識、飲食自我效能、飲食行為及體重控制成效的影響。研究對象為國小3-6年級體重過重及肥胖之學童，共53位（男生34人，女生19人)；研究介入為期10週，其中包含6堂每週一次、每次30分鐘的營養教育課程，並以問卷調查方式收集受試者前後測資料。結果顯示，營養教育介入後，學童在飲食行為（前測vs. 後測平均得分為56.9± 7.4 vs. 62.2± 8.8, p<0.001)、營養知識（前測vs. 後測平均得分為9.1± 1.9 vs. 11.0± 2.0, p<0.001）及飲食自我效能（前測vs. 後測平均得分為22.7± 4.2 vs. 24.3± 4.3, p=0.022）三部份皆有提升、進步，而BMI則無統計上顯著差異。藉由校園營養教育活動的介入，可有效改善學童與體重控制相關之飲食行為、營養知識及飲食自我效能。 The data reported by the Ministry of Education showed that prevalences of overweight and obesity among the elementary school children had reached to 25%. The purpose of this study is to investigate the effectiveness of nutrition education intervention for nutrition knowledge, self-efficacy, eating behavior and weight control among the elementary school children. The subjects were the 3rd-6th grade elementary school children, who were overweight and obese. A total of 53 (34 boys, 19 girls) subjects were recruited. The period of this study was ten weeks, included six, 30-minute sessions of nutrition education per week. A questionnaire was used for data collection. The results showed that the school children had significant differences in their eating behavior (pre-test vs. Post-test was 56.9? 7.4 vs. 62.2? 8.8, p <0.001), nutrition knowledge (pre-test vs. Post-test was 9.1? 1.9 vs. 11.0? 2.0, p <0.001) and dietary self-efficacy (pre-test vs. Post-test was 22.7? 4.2 vs. 24.3? 4.3, p = 0.022) after nutrition education intervention; however, there was no significant difference in BMI. This school-based, nutrition education effectively improved the school children's eating behavior, nutrition knowledge and dietary self-efficacy relative to weight control.
