背景：对办公室工作人员坐、站和走路的总量和模式的研究越来越多，但很少有研究使用客观测量的坐姿和站立。了解这些模式可以确定每天哪些时间适合进行干预，以活动取代静坐。方法：在英国的办公室工作人员（n = 164）的样本中安装了大腿穿戴式ActivPal加速计，并连续5天每天24小时佩戴该装置，包括周六和周日，洗澡和睡觉时。研究人员报告了ActivPal加速计记录的每天坐、站、走的时间和模式，以及坐/站转换的次数和频率。结果：工作日（10.6/4.1小时）和周末（10.6/4.3小时）的总坐/站时间相似。总步数在工作日（9682 +/- 3872）和周末（9518 +/- 4615）也相似。工作日中体力活动水平最高的时段是0700至0900、1200至1400和1700至1900；周末在1000点到1700点之间。在工作日的早上9点到12点、下午14点到17点、下午2点到23点以及周末的下午18点到23点之间，坐着的时间最多。在工作日，站立人数最多的时段是0700至1000,1700至2100，而周末则是1000至1800。在工作日，坐/站转换的最高次数发生在0800至0900之间，并一直保持到1800。周末最高的是1000 ~ 1400和1900 ~ 2000。结论：办公室工作人员在工作日和周末都表现出高水平的坐着。针对工作日和晚上（工作日和周末）的干预措施，以活动取代久坐，可能最有希望减少人口久坐行为水平，并增加居住在英国的办公室工作人员的身体活动水平。
Background: There is a growing body of research into the total amount and patterns of sitting, standing and stepping in office-based workers and few studies using objectively measured sitting and standing. Understanding these patterns may identify daily times opportune for interventions to displace sitting with activity.Methods: A sample of office-based workers (n = 164) residing in England were fitted with thigh-worn ActivPal accelerometers and devices were worn 24 hours a day for five consecutive days, always including Saturday and Sunday and during bathing and sleeping. Daily amounts and patterns of time spent sitting, standing, stepping and step counts and frequency of sit/stand transitions, recorded by the ActivPal accelerometer, were reported.Results: Total sitting/standing time was similar on weekdays (10.6/4.1 hrs) and weekends (10.6/4.3 hrs). Total step count was also similar over weekdays (9682 +/- 3872) and weekends (9518 +/- 4615). The highest physical activity levels during weekdays were accrued at 0700 to 0900, 1200 to 1400, and 1700 to 1900; and during the weekend at 1000 to 1700. During the weekday the greatest amount of sitting was accrued at 0900 to 1200, 1400 to 1700, and 2000 to 2300, and on the weekend between 1800 and 2300. During the weekday the greatest amount of standing was accrued between 0700 and 1000 and 1700 and 2100, and on the weekend between 1000 and 1800. On the weekday the highest number of sit/stand transitions occurred between 0800 to 0900 and remained consistently high until 1800. On the weekend, the highest number occurred between 1000 to 1400 and 1900 to 2000.Conclusion: Office based-workers demonstrate high levels of sitting during both the working week and weekend. Interventions that target the working day and the evenings (weekday and weekend) to displace sitting with activity may offer most promise for reducing population levels of sedentary behaviour and increasing physical activity levels, in office-based workers residing in England.
