Effect of COVID-19 Infection on Presenteeism

Abstract

Objective Presenteeism occurs when employees attend work despite experiencing problems and ill-health that require sick leave. This study examined whether presenteeism worsened following COVID-19 infection. Methods We used the DeSC, a large health insurance claims database. Participants were 9,241 individuals who responded to questionnaires at baseline (June 2020) and 6 months later, had been continuously insured for at least 6 months prior to baseline, and reported being employed. Propensity score matching was performed. Adjusted multiple logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of worsening presenteeism from baseline according to COVID-19 infection compared with non-infection. Results Conditional logistic regression analysis showed that the adjusted OR for presenteeism in the COVID-19 infected group was 1.555 (95% CI, 1.086–2.225). Conclusion The findings suggest that COVID-19 infection affected worsening of presenteeism.
