Increased use of shift work has led to more and more people working outside a traditional daytime schedule. Currently, approximately 20% of the labor force in developed countries is shift workers. Shift work can have devastating effects on employees' quality of life and sleep, leading to negative consequences for individuals and their families. This study evaluates the effect of different shift schedules (seven days/seven nights, fixed-day or fixed-night, and stand-by shift) on the sleep of oil rig shift workers.
In this cross-sectional study, 43 offshore workers from the National Iranian Drilling Company were enrolled. Subjects were asked to complete a questionnaire package consisting of the Epworth Sleepiness scale and Pittsburgh Sleep Quality Index (PSQI). Changes in sleep patterns were measured using actigraphy for different shift schedules.
The mean age of the participants was 35.9 ± 7.9 years and the mean tenure with the drilling company was 10 ± 6.8 years. The mean total sleep time was 353 ± 58 min. The seven day/seven night shift workers had less total sleep time than the other three groups of shift workers. The mean PSQI and Epworth Sleepiness scale scores were 6.77 ± 3.1 and 7.49 ± 4.3, respectively. Twelve shift workers (27%) were diagnosed with shift work disorder in the current study and 31 participants had poor sleep quality according to PSQI score (≥5).
Poor sleep quality is common in oil rig shift workers. Further research is needed to evaluate sleep problems in oil rig shift workers.
轮班工作的日益普及导致越来越多的人不在传统的白天工作时间工作。目前，发达国家约有 20%的劳动力是轮班工人。轮班工作会对员工的生活质量和睡眠产生破坏性影响，给个人及其家庭带来负面影响。本研究评估了不同轮班时间表（七天七夜、固定日或固定夜、待命班）对石油钻井平台轮班工人睡眠的影响。
在这项横断面研究中，共有来自伊朗国家钻井公司的 43 名海上作业人员入组。要求受试者完成一份问卷包，其中包括 Epworth 嗜睡量表和匹兹堡睡眠质量指数（PSQI）。使用活动记录仪测量不同轮班时间表下的睡眠模式变化。
参与者的平均年龄为 35.9 ± 7.9 岁，平均在钻井公司工作年限为 10 ± 6.8 年。平均总睡眠时间为 353 ± 58 分钟。七天七夜轮班工人的总睡眠时间比其他三组轮班工人少。PSQI 和 Epworth 嗜睡量表的平均得分为 6.77 ± 3.1 和 7.49 ± 4.3。在本研究中，12 名轮班工人（27%）被诊断为轮班工作障碍，31 名参与者根据 PSQI 评分（≥5）睡眠质量差。
石油钻井平台轮班工人普遍存在睡眠质量差的问题。需要进一步研究来评估石油钻井平台轮班工人的睡眠问题。
