OBJECTIVE
To assess the daily relationship between prior-night total sleep time (TST) and next-day, afternoon sleep propensity among firefighters operating from two popular fire department shift schedules.
METHODS
Dataset included 22 firefighters (24/48 shift schedule) and 20 firefighters (48/96 shift schedule). Daily TST was assessed using actigraphy and daily sleep propensity was assessed using the Epworth Sleepiness Scale (ESS), completed every afternoon.
RESULTS
Separate one-way repeated measures ANOVA indicated statistically significant differences among daily sleep propensity within each shift schedule. Separate Pearson product moment correlations indicated moderate relationships between prior-night TST and next-day, afternoon sleep propensity.
CONCLUSION
When firefighters slept less, sleep propensity the following day increased. Least TSTs occurred on nights prior to commuting suggesting firefighters likely begin shifts without sufficient sleep and drive home without sufficient sleep, then experience greatest sleep propensity.
目的
评估采用两种常见消防部门轮班时间表执勤的消防员前一晚总睡眠时间（TST）与次日下午睡眠倾向之间的每日关系。
方法
数据集包括22名消防员（24/48轮班时间表）和20名消防员（48/96轮班时间表）。使用活动记录仪评估每日TST，并使用爱泼华嗜睡量表（ESS）评估每日睡眠倾向，该量表于每天下午完成。
结果
单独的单因素重复测量方差分析表明，每个轮班时间表内的每日睡眠倾向之间存在统计学上的显著差异。单独的皮尔逊积差相关表明前一晚TST与次日下午睡眠倾向之间存在中等程度的关系。
结论
当消防员睡眠较少时，次日的睡眠倾向会增加。通勤前一晚的TST最少，这表明消防员可能开始轮班时睡眠不足，开车回家时也睡眠不足，然后睡眠倾向最大。
