This study investigates the prevalence of symptoms of shift work disorder in a sample of nurses, and its association to individual, health and work variables.
METHODOLOGY/PRINCIPAL FINDINGS: We investigated three different shift work disorder assessment procedures all based on current diagnostic criteria and employing symptom based questions. Crude and adjusted logistic regression analyses were performed with symptoms of shift work disorder as the dependent variable. Participants (n = 1968) reported age, gender, work schedule, commuting time, weekly work hours, children in household, number of nights and number of shifts separated by less than 11 hours worked the last year, use of bright light therapy, melatonin and sleep medication, and completed the Bergen Insomnia Scale, Epworth Sleepiness Scale, Global Sleep Assessment Questionnaire, Diurnal Scale, Revised Circadian Type Inventory, Dispositional Resilience (Hardiness) Scale--Revised, Fatigue Questionnaire, questions about alcohol and caffeine consumption, as well as the Hospital Anxiety and Depression Scale.
CONCLUSIONS/SIGNIFICANCE: Prevalence rates of symptoms of shift work disorder varied from 32.4-37.6% depending on the assessment method and from 4.8-44.3% depending on the work schedule. Associations were found between symptoms of shift work disorder and age, gender, circadian type, night work, number of shifts separated by less than 11 hours and number of nights worked the last year, insomnia and anxiety. The different assessment procedures yielded similar results (prevalence and logistic regression analyses). The prevalence of symptoms indicative of shift work disorder was high. We argue that three symptom-based questions used in the present study adequately assess shift work disorder in epidemiological studies.
本研究调查了护士样本中轮班工作障碍症状的流行情况，及其与个体、健康和工作变量的关系。
方法/主要发现：我们调查了三种不同的轮班工作障碍评估程序，这些程序均基于当前的诊断标准，并采用基于症状的问题。以轮班工作障碍症状为因变量进行了未经调整和调整后的逻辑回归分析。参与者（n=1968）报告了年龄、性别、工作时间表、通勤时间、每周工作小时数、家中的孩子数、过去一年中少于 11 小时分开的夜间和轮班次数、使用明亮光疗法、褪黑素和睡眠药物的情况，并完成了卑尔根睡眠量表、埃普沃斯嗜睡量表、全球睡眠评估问卷、日间量表、修订的昼夜节律类型量表、性格韧性量表-修订版、疲劳问卷、关于酒精和咖啡因摄入的问题，以及医院焦虑和抑郁量表。
结论/意义：轮班工作障碍症状的患病率因评估方法而异，范围为 32.4%-37.6%，因工作时间表而异，范围为 4.8%-44.3%。轮班工作障碍症状与年龄、性别、昼夜节律类型、夜间工作、少于 11 小时分开的轮班次数和过去一年的夜间工作次数、失眠和焦虑有关。不同的评估程序得出了相似的结果（患病率和逻辑回归分析）。轮班工作障碍症状的患病率很高。我们认为，本研究中使用的三个基于症状的问题足以在流行病学研究中评估轮班工作障碍。
