This study aimed to examine the association between rotating night shift work and subclinical athero-sclerosis among Chinese steelworkers.
We evaluated 3582 steelworkers who participated in the legally required health examination in 2017. Carotid intima-media thickness (CIMT) was measured using ultrasonography. Different exposure metrics of night shifts collected by face-to-face personal interviews were used to examine the relationship between night shift work and the mean CIMT.
The mean CIMT values were 0.66 (standard deviation 0.22) mm in the study population. Current shift workers shown higher mean CIMT compared to day workers. There were no significant associations between the current shift status, the duration of night shifts, the cumulative number of night shifts, the average frequency of night shifts, and the mean CIMT after all confounding factors adjusted both in male and female.
Rotating night shift work is not associated with subclinical atherosclerosis among steelworkers. Further large-scale prospective longitudinal studies are warranted to confirm our findings.
本研究旨在探讨中国钢铁工人轮班夜班工作与亚临床动脉粥样硬化之间的关系。
我们评估了 2017 年参加法定健康检查的 3582 名钢铁工人。使用超声检查测量颈动脉内膜中层厚度（CIMT）。通过面对面的个人访谈收集不同的夜班暴露指标，以检查夜班工作与平均 CIMT 之间的关系。
研究人群的平均 CIMT 值为 0.66（标准差 0.22）mm。与日班工人相比，当前轮班工人的平均 CIMT 更高。在所有混杂因素调整后，男性和女性中当前轮班状态、夜班持续时间、夜班累计次数、夜班平均频率与平均 CIMT 之间均无显著关联。
轮班夜班工作与钢铁工人的亚临床动脉粥样硬化无关。需要进一步开展大规模前瞻性纵向研究来证实我们的发现。
