| Summary: | 碩士 === 育達商業科技大學 === 資訊管理所 === 101 === Children are easily attracted to new technological products. They may get addicted to them and neglect the importance and benefit of exercise. High-oil, high-salt, and high-sugar diets contain high fat and also cause a larger load on their body. In fact, the so-called “health hazards” can be avoided through education, dietary control, adequate exercise, and adjustment of living habits. This study investigated the effects of body image and life pattern on Body Mass Index (BMI) of school children using some fourth-grade students of a musical class as an example. Factors affecting BMI were classified into four sub-systems, including body image, experience of being judged for body appearance, parents' dietary instruction, and effectiveness of nutrition education in school. The simulation software Vensim was used for modeling and simulation of dynamics. The purpose of this study was to gain an insight into the trend of BMI development among musical class students in elementary schools. Conclusions of this study were as follows: (1) Body image had a considerable effect on emotional stability. Although the effect varied slightly, it was generally positive. (2) Students with more health concepts tended to have a higher level of physical activity. (3) Students who spent more time on static activities that involved using technological products tended to have a poorer body image. (4) Students with more health concepts tended to have lower levels of obesity. (5) Parents’ socioeconomic status was a factor affecting physical activity of students at first and second grades. (6) It would be easier to influence elementary school students at lower grades, from the first to the fourth. The effect of nutrition education on their intake of high-calorie diets could be significantly greater. (7) Allowance was negatively related to health concepts among school children, especially those studying in the third and the fourth grades. (8) Frequency of high-calorie diets was negatively related to weight control beliefs.
