| Outline of Final Research Achievements |
In this study, bone mass, muscle mass and body fat mass and their distribution based on accurate body composition measurements, as well as lifestyle habits such as eating and exercise behavior, were examined as health information to be visualized. The results showed a positive correlation between body mass index (BMI), degree of obesity, muscle mass, bone mass and body fat percentage. In addition, BMI and degree of obesity showed particularly high correlations with muscle mass, body fat mass and body fat percentage. Furthermore, desire of thinness was associated with weight-loss behavior but not with physical activity, while exercise self-efficacy was associated with weight-loss behavior and physical activity. This raised concerns that the mere desire to be thin and subsequent weight-loss behavior may lead to a risk of muscle and bone mass deficiency and future osteoporosis and sarcopenia.

| Academic Significance and Societal Importance of the Research Achievements |
生活習慣病を予防し、生涯を健康に過ごすためには、子どものころから適切な生活習慣を確立することが必須である。しかしながら、そのための行動変容は容易ではない。本研究では、単なるやせ願望だけでは運動行動と結びつかず、骨量や筋量の不足リスクとなる可能性が示唆された。近年、減量目的のために、食事制限に偏ったダイエット行動が社会に多くみられるが、本研究結果は自らの健康状態を正確に把握することが適切な減量行動のために重要であることを示唆している。
