目的夜间和夜间工作比白天工作有更高的伤害风险。然而，先前的研究结果可能会受到回忆偏差和一天之间的差异造成的不可测量的混淆的影响。夜班和夜班工人。本研究调查过去一周的夜间和夜间工作是否会增加受伤风险，以减少回忆偏差和不可测量的混淆。方法我们将个人层面的69 200名员工(2008-2015年为167 726人年)的每日工作时间与11834名导致急诊室就诊或死亡的伤害登记信息联系起来。使用泊松回归模型对包括固定白天、晚上和夜间工作的全部人口以及分别从事白天和晚上或夜间工作的夜间和夜间工作的两个亚群进行了分析。结果夜间工作一周[发生率比(IRR)1.32，95%可信区间(CI)1.26~1.37]和夜间工作(IRR)1.33，95%可信区间(CI)1.25~1.41比白天工作有更高的伤害风险。夜间工作与夜间工作相似(IRR1.18，95%可信区间1.12~1.25)，夜间工作相似(IRR1.10，95%可信区间1.01~1.20)。尽管风险有所减弱，但在减少不可测量的混杂因素后，风险仍然较高。
Objectives Evening and night work have been associated with higher risk of injury than day work. However, previous findings may be affected by recall bias and unmeasured confounding from differences between day. evening and night workers. This study investigates whether evening and night work during the past week increases risk of injury when reducing recall bias and unmeasured confounding.Methods We linked daily working hours at the individual level of 69 200 employees (167 726 person years from 2008-2015), primarily working at hospitals to registry information on 11 834 injuries leading to emergency room visits or death. Analyses were conducted with Poisson regression models in the full population including permanent day, evening and night workers, and in two sub-populations of evening and night workers, with both day and evening or night work, respectively. Thus, the exchangeability between exposure and reference group was improved in the two sub-populations.Results Risk of injury was higher after a week with evening work [incidence rate ratio (IRR) 1.32, 95% confidence interval (CI) 1.26-1.37] and night work (IRR 1.33, 95% CI 1.25-1.41) compared with only day work. Similar, although attenuated, estimates were found for evening work among evening workers (IRR 1.18, 95% CI 1.12-1.25), and for night work among night workers (IRR 1.10, 95% CI 1.01-1.20).Conclusion There is an overall increased risk of injury after a week that has included evening or night work compared with only day work. Though attenuated, the higher risk remains after reducing unmeasured confounding.
