Outline of Final Research Achievements |
The aim of this study was to examine the association of the balance of daily movement behaviors (sleep, physical activity, and sedentary behavior) with health and well-being among workers. The results showed that a day with less sedentary behavior and more sleep and physical activity was associated with better physical health (cardiometabolic health) and well-being (e.g. happiness and work engagement). On the other hand, a lower psychological distress was related to a day with less sedentary behavior and light-intensity physical activity and more sleep and moderate- to vigorous-intensity physical activity. It was also suggested that these associations may differ by domain of behavior (e.g. occasions and days of the week) and characteristics (e.g. gender).

Academic Significance and Societal Importance of the Research Achievements |
1日の身体行動に費やす時間は互いに依存関係にあるため、健康づくりを推進する際には、いずれか一つの行動に着目するのではなく24時間の身体行動を包括的に捉える視点が必要である。しかし、厚生労働省「健康づくりのための身体活動・運動ガイド2023」では現時点で座位行動や睡眠に関する行動指針が含まれていない。本研究から得られた24時間の身体行動と様々な健康アウトカムの関連性についての知見は、現状の行動指針を発展させ、24時間の身体行動を包括的に捉えたガイドラインの作成に寄与することが期待される。
