Rotating shift work is common in high-hazard industries, despite documented associations with sleep disturbance and impairment. In the oil industry, where rotating and extended shift schedules are used to staff safety-sensitive positions, work intensification and increasing overtime rates have been broadly documented over the last few decades. Research on the impacts of these work schedules on sleep and health has been limited for this workforce.
We examined sleep duration and quality among rotating shift workers in the oil industry and explored associations between schedule characteristics, sleep, and health outcomes. We recruited hourly refinery workers from the West and Gulf Coast oil sector members of the United Steelworkers union.
Impaired sleep quality and short sleep durations were common and associated with health and mental health outcomes common among shift workers. Shortest sleep durations followed shift rotations. Early rise and start times were associated with shorter sleep duration and poorer sleep quality. Drowsiness and fatigue-related incidents were common.
CONCLUSION/APPLICATION TO PRACTICE: We observed lower sleep duration and quality and increased overtime in 12-hour rotating shift schedules. These long workdays with early start times may reduce available hours for quality sleep; here they were associated with reduced exercise and leisure activity which correlated with good sleep. This safety-sensitive population appears severely impacted by poor sleep quality, which has broader implications for process safety management. Later start times, slower rotation, and a reconsideration of two-shift schedules are interventions to consider for improving sleep quality among rotating shift workers.
尽管有文献证明轮班工作与睡眠障碍和睡眠质量受损有关，但在高风险行业中，轮班工作仍很常见。在石油行业中，为了配备安全敏感岗位，会采用轮班和延长轮班时间表，过去几十年，工作强度和加班率的增加已被广泛记录。对于这些轮班工作时间表对睡眠和健康的影响的研究，针对该劳动力的研究一直很有限。
我们研究了石油行业轮班工人的睡眠时间和睡眠质量，并探讨了时间表特征、睡眠与健康结果之间的关系。我们招募了来自美国钢铁工人联合会西部和墨西哥湾沿岸石油部门的小时炼油厂工人。
睡眠质量受损和睡眠时间短很常见，与轮班工人常见的健康和心理健康结果有关。睡眠时间最短的是轮班之后。早起和开始时间与睡眠时间短和睡眠质量差有关。嗜睡和疲劳相关事件很常见。
结论/对实践的应用：我们观察到 12 小时轮班时间表的睡眠时间和质量更差，加班时间更多。这些长工作日，早起开始时间可能会减少高质量睡眠的可用时间；在这里，它们与减少锻炼和休闲活动有关，而锻炼和休闲活动与良好的睡眠有关。这个安全敏感的人群似乎受到严重影响，睡眠质量较差，这对工艺安全管理有更广泛的影响。推迟开始时间、较慢的轮班和重新考虑两班制是改善轮班工人睡眠质量的干预措施。
