To investigate if exposure to an unusually low workload when ill can trigger taking sick leave.
A case-crossover design was applied to 546 sick-leave spells obtained from a cohort of 1430 employees within six Swedish workplaces. New sick-leave spells were reported from the workplaces during 3 to 12 months follow-up. Exposure was assessed in structured participant interviews at sick leave. Case and control periods from the same individual were sampled according to the matched-pair and usual-frequency approaches. Results are presented as odds ratios with surrounding 95% confidence intervals.
The odds ratio of sick leave on a day with an unusually low workload was 2.57 (confidence interval, 1.07-6.16).
Becoming ill on a day with a lower workload than usual can trigger the decision to take sick leave.
调查患病时工作量异常低是否会导致请病假。
本研究采用病例交叉设计，对来自瑞典 6 家工作场所的 1430 名员工队列中的 546 个病假进行分析。在 3 至 12 个月的随访期间，从工作场所报告新的病假情况。在病假期间通过结构化的参与者访谈来评估暴露情况。根据匹配对和常规频率方法，从同一人抽取病例期和对照期。结果以比值比及其 95%置信区间表示。
工作量异常低的那一天请病假的几率比为 2.57（95%置信区间，1.07-6.16）。
与平时相比，在工作量较低的那天生病可能会促使人们决定请病假。
