Abstract:	一般大學新生入學後，開始有選擇食物的自主權，常出現飲食不均衡及運動不足等問題，造成熱量攝取與消耗不平衡，導致入學後體重明顯增加，容易形成過重或肥胖的現象。本研究以營養與運動教育資訊網頁介入大一新生預防肥胖的發生。招募自願參與研究之大學新生245人，隨機分配至實驗組（n=154）與對照組（n=119）。透過電子郵件將營養與運動教育資訊網課程網址發送給實驗組，對照組不做任何介入。問卷包括營養與運動知識、食物頻率問卷、活動與運動習慣及網頁教材學習動機量表。介入後，實驗組整體「營養與運動知識」明顯提升，特別是子構面「食物份量與代換」和「活動與運動習慣」等知識觀念。實驗組在食物攝取頻率無明顯改變，但蔬菜（體位正常者）和水果（尤其是體位過重與肥胖者）攝取份量增加。對照組高營養密度食物攝取頻率減少，每天從6.08次明顯減少至4.72次。整體身體活動（活動與運動習慣）兩組皆無明顯改變。實驗組過重與肥胖者BMI有下降趨勢。實驗組在網頁教材學習動機平均分數皆高於中位數3分，其中「滿意度」分數最高(3.6分)。IMB模型中，營養與運動「知識」對「行為」有正向影響，且網頁教材學習「動機」對「行為」也有正向影響。營養與運動教育資訊網介入大一新生，有助於提升整體營養與運動知識，避免減少高營養密度食物攝取頻率，可能有助於新生在學期間增加蔬菜（體位正常者）和水果攝取份量，維持入學前較佳的飲食行為，預防體位正常者入學後體重快速增加，並有助於減輕過重與肥胖者之體重。 Most freshmen gain excess body weight because of extra food intake and physical inactivity during first year of college. Such unhealthy behavior leads college students to the condition of overweight or obesity in the period of college and adulthood. The purpose of this study was to evaluate the effectiveness of web-based nutrition and exercise intervention in obesity prevention among freshmen. Freshmen were volunteered and randomly assigned into the intervention group (I, n=154) or compared group (C, n=119), respectively. The online nutrition and exercise program was sent to I via e-mail. Participants in C did not receive any information during the study. The questionnaires, knowledge, food frequency, activity with exercise and motivation, were completed by participants. After intervention, knowledge was significantly improved in I, especially in the aspect of portion size and activity plus exercise. Increased consumption of vegetables and fruits in I was observed, although the total amount of High nutrient-density foods (HNDFs) intake was unchanged. On the other hand, the pattern of HNDFs intake in C was decreased from 6.08 to 4.72 times/ day. There was no obvious change in physical activity for both groups. BMI may be lowered in the group of overweight and obesity freshmen. Mean of motivation of online material learning was above median level (3.0). The highest score was subscale of satisfaction (3.6). Regarding IMB model, there was positively correlated among the relationships of behavior and knowledge as well as motivation. These results indicated the effectiveness of the nutrition and exercise web page-lectures with reliable learning motivation on improving knowledge maintaining more healthy eating behavior associated with increasing vegetable plus fruit consumption and possibly preventing weight gain in freshmen.
