This study aimed to verify whether sleep quality is a mediator of the relationship between burnout, stress and multisite pain in healthcare workers in a longitudinal study with 12 months of follow-up during the COVID-19 pandemic. Online questionnaires were used for data collection. The sociodemographic questionnaire contained personal and occupational data. The short version of the Copenhagen Psychosocial Questionnaire (COPSOQ II-Br) was used to assess burnout and stress. The Pittsburgh Sleep Quality Index (PSQI-Br) assessed sleep quality over one month. The Nordic Musculoskeletal Questionnaire (NMQ) aimed to identify the presence of multisite musculoskeletal pain in the last 12 months and the last 7 days. Mediation analysis was used to verify whether the effect of the predictor variables (burnout and stress) on the dependent variable (number of pain sites in the last 12 months and 7 days) was due to an intervening variable (sleep quality). Stress and burnout were associated with multisite pain in healthcare workers in the last 12 months and the last 7 days. Sleep quality was a significant mediator of this association in the last 12 months, indicating that some of the association between burnout, stress and multisite pain can be explained by poor sleep quality. Thus, a comprehensive approach to long-term multisite pain should consider psychosocial aspects such as burnout, stress and sleep quality.
本研究旨在通过一项在新冠疫情期间进行的为期12个月随访的纵向研究，验证睡眠质量是否是医护人员职业倦怠、压力与多部位疼痛之间关系的中介变量。采用在线问卷进行数据收集。社会人口学问卷包含个人和职业数据。使用哥本哈根心理社会问卷简版（COPSOQ II-Br）评估职业倦怠和压力。匹兹堡睡眠质量指数（PSQI-Br）评估一个月内的睡眠质量。北欧肌肉骨骼问卷（NMQ）旨在确定过去12个月和过去7天内是否存在多部位肌肉骨骼疼痛。采用中介分析来验证预测变量（职业倦怠和压力）对因变量（过去12个月和7天内的疼痛部位数量）的影响是否归因于一个中介变量（睡眠质量）。在过去12个月和过去7天内，压力和职业倦怠与医护人员的多部位疼痛相关。在过去12个月中，睡眠质量是这种关联的一个显著中介变量，这表明职业倦怠、压力与多部位疼痛之间的部分关联可以用睡眠质量差来解释。因此，对于长期多部位疼痛的综合治疗方法应考虑职业倦怠、压力和睡眠质量等心理社会因素。
