This study aimed to understand the prevalence of sleep disorders among shift workers and analyze the relationship between sleep disorders and shift work. . Baseline data were collected from subjects who were then followed for 2 years in a prospective cohort study. The cohort ultimately included 2453 people starting in May 2013, and follow-up with questionnaires was performed in July 2014 and October 2015. Sleep disorders were assessed with the Pittsburgh sleep quality index. . The risk of sleep disorders among two-shift workers (relative risk [RR] = 1.318, 95% confidence interval [CI] [1.025, 1.695]), three-shift workers (RR = 1.326, 95% CI [1.048, 1.679]) and four-shift workers (RR = 1.334, 95% CI [1.062, 1.675]) was higher than that among non-shift workers, and an increasing trend was observed in sleep disorders as the number of shifts increased. . Shift workers have a higher incidence of sleep disorders than non-shift workers. An increasing linear trend was observed between the number of shifts and sleep disorders. In the petroleum industry, it is necessary to decrease the frequency of shifts to reduce the incidence of sleep disorders among shift workers.
本研究旨在了解轮班工人中睡眠障碍的患病率，并分析睡眠障碍与轮班工作之间的关系。 采用前瞻性队列研究，对研究对象进行了基线数据收集，随后对其进行了 2 年的随访。该队列最终纳入了 2013 年 5 月开始的 2453 人，2014 年 7 月和 2015 年 10 月进行了问卷调查随访。睡眠障碍采用匹兹堡睡眠质量指数进行评估。 与非轮班工人相比，两班制工人（相对风险 [RR] = 1.318，95%置信区间 [CI] [1.025, 1.695]）、三班制工人（RR = 1.326，95% CI [1.048, 1.679]）和四班制工人（RR = 1.334，95% CI [1.062, 1.675]）发生睡眠障碍的风险更高，且随着轮班次数的增加，睡眠障碍的风险呈递增趋势。 轮班工人发生睡眠障碍的风险高于非轮班工人，轮班次数与睡眠障碍之间呈线性递增趋势。在石油行业，有必要减少轮班频率，以降低轮班工人睡眠障碍的发生率。
