Shift work is associated with sleep and health problems. Tolerance to shift work is reported to decrease with age. Shift work tolerance should be considered in different shift work populations. The aim of the study was to examine the relationship between age, shift work exposure, shift type, and morningness and sleep/health problems in oil rig shift workers.
A total of 199 workers participated. They worked either two weeks of 12-h day shifts (n = 96) or two weeks of swing shifts (n = 103) (one week of 12-h night shifts followed by one week of 12-h day shifts), followed by four weeks off work. The workers filled out questionnaires on demographics, work, sleep, and health.
We found no significant associations between age or years of shift work exposure and any of the sleep, sleepiness, or health parameters. There was a significant association between shift type and sleep duration, showing that swing shift workers had longer sleep duration than day shift workers. In addition, we found a significant association between the interaction age*, shift type, and sleep duration, where sleep duration was negatively associated with age for the swing shift workers and positively associated with age for the day shift workers. There were significant associations between morningness and sleep latency, sleep efficiency, and insomnia.
Older workers may tolerate shift work well. Age, shift work exposure time, and shift type seemed not to affect shift work tolerance in this population. However, this may be due to a healthy worker effect and/or selection bias.
轮班工作与睡眠和健康问题相关。据报道，对轮班工作的耐受性会随着年龄增长而下降。应在不同的轮班工作人群中考虑轮班工作耐受性。本研究的目的是探讨石油钻井平台轮班工人的年龄、轮班工作暴露、轮班类型、晨型偏好与睡眠/健康问题之间的关系。
共有199名工人参与。他们要么进行为期两周的12小时日班工作（n = 96），要么进行为期两周的倒班工作（n = 103）（一周12小时夜班，随后一周12小时日班），然后休息四周。工人们填写了关于人口统计学、工作、睡眠和健康的问卷。
我们发现年龄或轮班工作暴露年限与任何睡眠、嗜睡或健康参数之间均无显著关联。轮班类型与睡眠时间之间存在显著关联，表明倒班工人的睡眠时间比日班工人长。此外，我们发现年龄*、轮班类型和睡眠时间之间的交互作用存在显著关联，其中倒班工人的睡眠时间与年龄呈负相关，日班工人则呈正相关。晨型偏好与睡眠潜伏期、睡眠效率和失眠之间存在显著关联。
年长工人可能对轮班工作耐受性良好。在该人群中，年龄、轮班工作暴露时间和轮班类型似乎不影响轮班工作耐受性。然而，这可能是由于健康工人效应和/或选择偏倚。
