兒童肥胖是重要、全球性的公共衛生議題；發展出更有效、低成本以兒童爲中心的介入計畫降低肥胖兒童肥胖程度是必要的。爲達此需求，本研究發展出一“綜合屬性（包括內容、互動性、控制性、管道與客觀性）介入減重方法”，用以協助肥胖兒童（重高指數≥1.20）進行減重及改善其知識、態度與行爲。結果顯示822名四年級學童中，肥胖的盛行率爲15.9%(n=140)。本研究採實驗性、隨機研究設計，所篩檢出之肥胖兒童均接受前測（做爲比較基礎）與後測（介入後滿一個月），包含體位測量（包括身體質量指數、重高指數、體脂肪比率、三頭肌與肩胛肌下皮下脂肪厚度測量）與問卷施測（包括與肥胖及減重相關之知識、態度與行爲量表）。140名肥胖兒童中，完成研究的有118名（實驗組66名，控制組52名）。本研究結果發現：經由體位測量的比較顯示此一“綜合屬性介入減重方法”能有效的減輕兒童肥胖的程度(p<.05)，以及顯著的增加肥胖兒童對於肥胖及減重的知識(p<.001)；關於行爲方面，可能可以達到某些程度的改善(p=.057)；但對於態度則發現無明顯的變化(p=.597)。爲達更有效的減重，建議在此“綜合屬性介入減重方法”中可加入另一重要屬性－“個別性”；以期能更有利於改變肥胖學童的態度。

Childhood obesity is an important global public health issue. There is a need for more effective, low cost and child-centered intervention programs for reducing body weight. In response to this need, we developed a mix of attributes approach (including content, interactivity, control, channel, and objectivity) to help obese children (weight-for-length index, WLI≥1.20) reduce their body weight and improve their knowledge, attitude, and behavior. The prevalence of obesity in our sample was 15.9% (140 obese children out of 882 children studying in the fourth grade). An experimental, randomized research design was conducted in this study. Anthropometric measurements (including Body Mass Index [BMI], WLI, body fat percentage, triceps, and subscapular skinfold thickness) and questionnaires (including the Scale of Obesity and Body Weight Loss Knowledge, Attitude, and Practice) were evaluated at baseline (pretest) and after one month of the intervention (posttest) for all obese children. Of 140 obese children, 118 completed this study (66 in the experimental group, 52 in the control group). The mix of attributes approach significantly reduced the degree of obesity revealed in anthropometric measurements. (p<.05) This approach also significantly improved obese children's knowledge (p<.001) and slightly improved their behaviors (p=.057); however, this program did not change the children's attitudes so easily (p=.597). To more effectively lose weight, we suggest an additional attribute, “individuality”, as a means of increasing efforts to change attitudes in obese children.
