近來飲食西化，青少年飲食攝取不均、運動不足，肥胖青少年會有70%發展為肥胖成人，體重過重若無法即時控制，日後併發代謝症候群的機率遠高於體位正常者，本校學生數為1545人，根據102學年度身體質量指數檢測結果，體位過重及肥胖佔全校總人數29％，為提高體位適中比率，利用同儕鼓勵，吸引參與率，廣納更多需要減重的族群，活動以階段性介入飲食及有氧運動講座、體重計、記步器及紀錄等，結果觀察到本系列活動分九階段進行，合計參加達1124人次，其中健康體重測量計358人參加，減重計198人（55.3%），減210.7公斤，以BMI≧27組（76%）最高，減重26.5公斤，增重則以BMI≦18.5組（29.3%）最高，增重39公斤，且BMI≧24參加者較前102學年度體重控制班多30人，平均每人減重多2.9公斤，而從知能及行為結果顯示，若排除學生自我意識，其皆有再加強飲食及生活習慣正確觀念的必要性，故本研究結果觀察到成效且具發展性推廣利用，增進校園教職員工生正確選擇健康體位新生活。
