Outline of Final Research Achievements

From the questionnaire survey and accelerometer measurements in this study, it was confirmed that about 80% of desk workers, which is estimated to be more than half of all workers, are "sedentary" all day long during the working day, and that a workplace-wide program to reduce sedentary behavior could have a positive impact on the majority of desk workers.It was also suggested that the tailored messages and advice to the family and social characteristics of the target population could make the intervention more effective.The semi-structured interviews with the workers of the company introducing the standing desk revealed the usefulness and challenges of using the standing desk as an environmental approach as the core of the intervention program.

Academic Significance and Societal Importance of the Research Achievements

我が国の就労者は世界的にみても座位時間・労働時間ともに長いにもかかわらず、介入プログラムの開発はおろか、デスクワーカーの座位行動の実態さえも十分に分かっていない。そのことから本研究成果は、欧米とは異なった社会規範や雇用慣行、職場環境を持つ我が国における就労者の座位行動是正アプローチを構築するための重要なエビデンスの一つとなった。
