| Outline of Final Research Achievements |
This study aims to examine the extent to which sitting time during work and leisure time, measured by wearable devices, affects workers' cardiovascular and autonomic nervous system responses.
Data were collected from 60 workers in 2021, and about 30 workers in 2022, and each worker was asked to wear the wearable device 24 hours a day for seven days (at least four working days and at least one holiday) and to complete a questionnaire to measure and investigate (1) time spent in daily activities (sleeping, working, sitting, etc.), (2) physical activity, (3) heart rate variability, (4)cardiorespiratory fitness. Due to the large amount of data per person, processing the data takes time. Still, preparations are underway for the future publication of the results (at academic conferences and in papers).

| Academic Significance and Societal Importance of the Research Achievements |
近年、座位行動と健康リスクの関係が明らかになりつつある。しかし、勤務中の座位行動に関する知見は非常に不足しており、座位行動の労働衛生的側面を考慮した研究が不十分である。本研究では、勤務中に行われる長時間の座位行動が労働者の「職業性有害因子」となり得る可能性があるという視点から、“業務負荷”のある勤務中の座位行動においては、余暇中の座位行動と同等またはそれ以上の健康リスクが生じる可能性があると仮説を立て、日常生活における重要なデータを収集した。特に勤務時間が長く、座位時間も長いと考えられる日本人労働者に関するエヴィデンスは、労働現場で対策検討に役立ち、体力科学及び労働衛生研究の進展に貢献できる。
