Shift work is associated with musculoskeletal pain and headaches, but little is known about how the intensity of shift work exposure is related to musculoskeletal pain and headaches. This study aimed to investigate whether a higher proportion of night shifts is associated with a higher occurrence of musculoskeletal pain and headaches. Furthermore, to investigate whether sleep duration can mediate this potential association.
The study included 684 nurses in rotating shift work who responded to a daily questionnaire about working hours, sleep, and pain for 28 consecutive days. The data were treated cross-sectionally.
A negative binomial regression analysis adjusted for age and BMI revealed that working a higher proportion of night shifts is not associated with a higher occurrence of musculoskeletal pain and headaches. On the contrary, those working ≥ 50% night shifts had a significantly lower occurrence of pain in the lower extremities than those who worked < 25% night shifts (IRR 0.69 95% CI 0.51, 0.94). There was no indication of a mediation effect with total sleep time (TST).
The results of this study indicate that working a higher proportion of night shifts is not associated with a higher occurrence of musculoskeletal pain and headaches.
轮班工作与肌肉骨骼疼痛和头痛有关，但对于轮班工作暴露的强度与肌肉骨骼疼痛和头痛之间的关系知之甚少。本研究旨在调查夜班比例是否与肌肉骨骼疼痛和头痛的发生率更高有关。此外，还调查了睡眠时间是否可以调解这种潜在的关联。
该研究包括 684 名从事轮班工作的护士，他们在 28 天内连续每天对工作时间、睡眠和疼痛进行问卷调查。数据以横截面形式进行处理。
经过年龄和 BMI 调整的负二项式回归分析显示，上夜班的比例较高与肌肉骨骼疼痛和头痛的发生率较高无关。相反，上夜班比例≥50%的护士下肢疼痛的发生率明显低于上夜班比例<25%的护士（IRR 0.69，95%CI 0.51，0.94）。总睡眠时间（TST）没有显示出中介作用的迹象。
本研究结果表明，上夜班的比例较高与肌肉骨骼疼痛和头痛的发生率较高无关。
