We aimed to explore the association between long working hours and health-related productivity loss (HRPL), due to either sickness, absenteeism or presenteeism, stratified by household income level.
From January 2020 to February 2020, data were collected using a web-based questionnaire. A total of 4197 participants were randomly selected using the convenience sampling method. The nonparametric association between weekly working hours and HRPL was determined. Subsequently, a stratified analysis was conducted according to household income (1st, 2nd, and 3rd tertiles). Finally, the differences in HRPL of the different working hour groups (<40, 40, 40-51, and ≥52 hours) were investigated using a multivariate linear regression model.
Long working hours were more significantly associated with HRPL, as compared to the 'standard' working hours (40 hours/week). A larger proportion of productivity loss was associated with the presenteeism of workers, rather than absenteeism. The relationship between HRPL and weekly working hours was more prominent in the lower household income group.
The results of our study indicate that HRPL is associated with long working hours, especially in the lower household income group. Reducing the workload for the individual employee to a manageable level and restructuring sick leave policies to effectively counteract absenteeism and presenteeism may be a feasible option for better labor productivity and employee health.
我们旨在探讨长时间工作与因疾病、旷工或出勤主义导致的与健康相关的生产力损失（HRPL）之间的关联，并按家庭收入水平进行分层。
2020年1月至2020年2月，使用基于网络的问卷收集数据。采用便利抽样方法随机选取了4197名参与者。确定每周工作时间与HRPL之间的非参数关联。随后，根据家庭收入（第1、第2和第3三分位数）进行分层分析。最后，使用多元线性回归模型研究不同工作时间组（<40、40、40 - 51和≥52小时）的HRPL差异。
与“标准”工作时间（每周40小时）相比，长时间工作与HRPL的关联更为显著。更大比例的生产力损失与员工的出勤主义有关，而非旷工。HRPL与每周工作时间之间的关系在低收入家庭组中更为突出。
我们的研究结果表明，HRPL与长时间工作有关，尤其是在低收入家庭组中。将单个员工的工作量减少到可管理的水平，并调整病假政策以有效应对旷工和出勤主义，可能是提高劳动生产率和员工健康的可行选择。
