本研究之主要目的在瞭解實施涵蓋學童及家長教育之降低脂肪攝取營養教育課程對國小高年級學童降低脂肪攝取營養知識、態度、飲食行為及自我效能的影響。研究者以立意取樣的方式,選擇台北市大安區學童家庭社經背景相似的二所國小五年級各兩個班級共112位學童為研究對象。實驗組(N=53)接受的教育介入為「減脂大進擊」降低脂肪攝取營養教育課程,包括每週一次(為期八週)的學童營養教育課堂教學、每兩週發送一次(共四份)的家長營養教育簡訊,以及一次家長座談會;而控制組(N=59)並無任何相關的介入活動。在介入前、後一週分別對實驗組及控制組學童進行降低脂肪攝取營養知識、態度、飲食行為及自我效能前、後測評量,並在介入結束後第六週對實驗組學童進行後後測評量,以瞭解教育介入的成效。研究結果發現:1.實驗組學童接受降低脂肪攝取營養教育課程介入之後,其降低脂肪攝取營養知識、態度、飲食行為及自我效能顯著改善,且至少維持至介入後第六週。2.不同性別、學業成績、體型、家庭社經地位及家長參與程度的實驗組學童在降低脂肪攝取營養知識、態度、飲食行為及自我效能上幾乎全有明顯的介入效果,只是有些不同背景的學童在某些降低脂肪攝取評量項目的介入成效上有差異,唯一例外的是,家長低度參與的學童幾乎沒有顯著成效。3.學童學業成績為影響降低脂肪攝取營養知識的重要背景因素,學童降低脂肪攝取營養知識能影響營養態度,營養態度經由對自我效能的影響,進而影響飲食行為。本研究證實了有家長參與之學童降低脂肪攝取營養教育介入計畫的可行性及有效性,且家長的參與程度對學童降低脂肪攝取營養教育課程之介入成效有正向的影響。
The purpose of this study was to access the effect of the reducing fat intake nutrition education program including children and parents’ education on 5th graders. Two elementary schools in Da-An district of Taipei city participated in this study. The children of experimental group (N=53) were treated with eight-session classroom nutrition education program-one session per week. And their parents’ nutrition education included four newsletters and one seminar. The control group (N=59) was not treated with any educational intervention. The effectiveness of the program was evaluated by assessing children’s reducing fat intake nutrition knowledge, nutrition attitude, dietary behavior and self-efficacy one week (posttest) and six weeks (follow-up test) after completion of the intervention. The results indicated that: (1) The program significantly improved children’s reducing fat intake nutrition knowledge, nutrition attitude, dietary behavior and self-efficacy, and the effect lasted at least six weeks. (2) The program was effective despite of children’s sex, academic achievement, BMI and family social economic status, but not children with low degree of parents’ involvement. (3) Children’s academic achievement could predict their reducing fat intake nutrition knowledge, and nutrition knowledge could predict nutrition attitude, and thereafter self-efficacy and dietary behavior. The results supported the feasibility and importance of parental involvement in the children’s nutrition education program.
