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.
