这项横断面研究的目的是描述日本普通人群久坐时间和身体活动（PA）的模式和水平。共有1,740名年龄≥40岁的日本社区居民参与了这项研究。使用三轴加速度计连续7天评估久坐时间和PA。按性别、年龄组（40-64岁、65-74岁和≥75岁）和体重指数（BMI; <25和≥25 kg/m2）计算日常模式、久坐时间和PA水平。参与者有一半醒着的时间是久坐不动的，其中32.7%的时间是在≥30分钟的长时间运动中积累的，而中度到剧烈的PA （MVPA）只有54.4分钟/天（7%的醒着时间）（11.8分钟/天，≥10分钟）。除了总久坐时间外，男性的久坐时间更长，每久坐一小时的休息时间也比女性少。与年龄≥75岁和BMI较高（≥25 kg/m2）的参与者相比，年龄较小且BMI较低的参与者也观察到类似的趋势。此外，年龄≥75岁和BMI较高的参与者在≥10分钟的比赛中累积的MVPA分钟更少。在≥10分钟的回合中，只有34.8%的人群达到≥150分钟/周MVPA的推荐水平。日本成年人在长时间的运动中积累了很大比例的久坐时间，而在持续的MVPA运动中积累了很少的时间，而且很少有人符合目前的PA指南。
The purpose of this cross-sectional study was to describe the patterns and levels of sedentary time and physical activity (PA) in a general Japanese population. A total of 1,740 community-dwelling Japanese adults aged ≥40 years participated in this study. Sedentary time and PA were assessed for 7 consecutive days using a tri-axial accelerometer. Daily patterns and levels of sedentary time and PA were calculated by sex, age group (40–64, 65–74, and ≥75 years), and body mass index (BMI; <25 and ≥25 kg/m2). Participants spent half of their waking time being sedentary, 32.7% of which was accumulated in prolonged bouts ≥30 minutes, versus only 54.4 minutes/day (7% of waking time) as moderate-to-vigorous PA (MVPA) (11.8 minutes/day in bouts ≥10 minutes). In addition to total sedentary time, men had longer prolonged sedentary bouts and fewer breaks per sedentary hour than women. Similar trends were observed in participants aged ≥75 years and those with a higher BMI (≥25 kg/m2) compared to those with a younger age and lower BMI. Moreover, participants aged ≥75 years and those with a higher BMI accumulated fewer MVPA minutes in bouts ≥10 minutes. Only 34.8% of the population met the recommended level of ≥150 minutes/week MVPA in bouts ≥10 minutes. Japanese adults accumulated a large proportion of total sedentary time in prolonged bouts but few minutes in sustained bouts of MVPA, and few of them met the current PA guideline.
