Objective: This study aimed to investigate the impact of diabetes status on presenteeism in companies in Japan.
Methods: A cross-sectional study was conducted among workers aged 40 years or older. Using medical examination results and health insurance claims data, participants were classified as normal, borderline, or diabetic. The diabetic group was further classified as untreated or treated. The Quantity and Quality (QQ) method was used as an evaluation index of presenteeism. Logistic regression analysis was performed to predict presenteeism loss.
Results: Data on 13,292 people were analyzed. Presenteeism loss was significantly higher in the diabetic group versus the normal group. The untreated group did not differ from the normal group, but presenteeism loss was significantly higher in the treated group.
Conclusions: Presenteeism loss may occur among diabetic workers in Japan and can be caused by diabetes treatment.
