Outline of Final Research Achievements

The purpose of this study was to clarify the current status of children's lifestyle habits of sleep, exercise, and breakfast, the starting point of their lifestyle rhythms, and the relationship between lifestyle rhythms and vitality. The main results showed that accelerometry-measured physical activity showed a curvilinear change from elementary to junior high school age and that the duration of activity began to decrease after entering junior high school. Additionally, it was found that wake-up time was related to children's vitality. However, there was no relationship observed between physical activity and QOL, nor between physical activity and sleep.

Academic Significance and Societal Importance of the Research Achievements

子どもの健やかな成長は我が国の社会的課題の一つである。身体活動，睡眠，朝食の生活習慣は健やかな成長に大切な要素である。本研究の学術的意義の一つは，小学４年生から中学２年生まで5年間の身体活動の縦断変化を示せたことである。中等度強度以上，低強度，座位の身体活動強度別に変化を示せた。国内外の子どもの身体活動ガイドラインには中等度強度以上と座位時間が強調されることが多く，今後我が国のガイドラインを考えていく上で本研究の成果は社会的意義が高い。
