背景
比较了两个轮班工作中睡眠前后的总睡眠时间与工作期间的活动水平之间的关系。
方法
使用手腕上的活动检测装置对 17 名年龄从 34 岁到 55 岁不等的轮班工人进行了活动水平监测。轮班包括早班（6:30 至 15:15）和晚班（15:15 至 24:00），每周轮换一次。控制年龄后计算偏相关系数。
结果
早班后的总睡眠时间与睡前（r=-0.42）或睡后（r=-0.36）的活动次数显着相关。夜班后的总睡眠时间与睡前（r=-0.39）或睡后（r=-0.32）的活动计数之间也存在显着关系。早班受试者的平均总睡眠时间为349分钟，明显低于晚班后的睡眠时间（382分钟）。此外，早班的活动次数明显高于晚班。
结论
在轮班工人中，睡眠时间与睡眠前后活动之间的负相关关系变得很明显。
BACKGROUND
The relationship between total sleep time and activity levels during work before or after sleep in two rotating work shifts was compared.
METHOD
Monitoring of activity levels using an activity-detecting device in the wrist was conducted in 17 rotating shift workers, who ranged in age from 34 to 55 years. The work shifts, consisting of a morning shift (6:30 to 15:15 hours) and an evening shift (15:15 to 24:00 hours), were rotated on a weekly basis. Partial correlation coefficient was calculated after controlling for age.
RESULTS
The total sleep time after the morning shift was significantly related to the activity count before sleep (r=-0.42) or after sleep (r=-0.36). There was also a significant relationship between total sleep time after the evening shift and the activity count before sleep (r=-0.39) or after sleep (r=-0.32). The mean total sleep time of the subjects for the morning shift was 349 minutes, which was significantly lower than that after the evening shift (382 minutes). In addition, the activity count during the morning shift was significantly higher than that during the evening shift.
CONCLUSIONS
The negative relationship between sleep time and activity before or after sleep became clear in shift workers.
