目的研究日本不同职业活动类型工人的久坐行为和体力活动模式。设计2013- 2015年的横断面观察性研究。设置日本两个地方社区。参与者40-64岁的全职工人（n=345; 55%的男性）和居住在两个城市的人。主要结果测量从7天的加速度计数据，平均总久坐时间，长时间的久坐不动和轻度和中度到剧烈强度的体力活动（LPA和MVPA）与加速度计佩戴时间的比例以及每久坐小时的休息次数在四个时间段内进行了确定：工作时间、工作日、非工作时间和非工作日。这些久坐的行为和体力活动的措施，在四个时间段的工人与四个自我归因的职业活动类型（主要是坐，站，走，体力劳动），调整社会人口属性。结果在工作时间内，坐着工作的人有更长的久坐时间（总：p
Objectives To examine patterns of sedentary behaviour and physical activity, among Japanese workers with differing occupational activity types.Design A cross-sectional observational study in 2013-2015.Setting Two local communities in Japan.Participants Full-time workers aged 40-64 years (n=345; 55% men) and who lived in two cities.Main outcome measures From accelerometer data for 7 days, mean overall sedentary time, prolonged bouts of sedentary time and light-and moderate-to vigorous-intensity of physical activity (LPA and MVPA) as a proportion of accelerometer wear time and number of breaks per sedentary hour were identified for four time periods: working hours, workdays, non-work hours and non-workdays. These sedentary behaviour and physical activity measures in the four time periods were examined among workers with four self-attributed occupational activity types (mainly sitting, standing, walking, and physical labour), adjusting for sociodemographic attributes. Diurnal patterns of sedentary behaviour, LPA, and MVPA were examined.Results In working hours, those with a sitting job had significantly more total and prolonged sedentary time (total: p
