Abstract: Objective: The purpose of our study was to determine the association of type 1 diabetes mellitus (T1DM) and the risk of herpes zoster (HZ).<br />Methods: In this cohort study, we selected 4736 patients with T1DM registered in the Catastrophic Illness Patient Database who received insulin therapy before 2003 and 18944 participants without DM who were selected by frequency matched based on sex and age. Cox proportional hazard regression analysis was used to measure the hazard ratios (HRs) of HZ in the T1DM group compared with that in the non-T1DM group.<br />Results: Cox proportional hazard regression analysis showed that the adjusted HR of HZ was 2.38 times higher for patients in the T1DM group (95% CI = 1.77-3.19) than for those in the non-T1DM group. According to diabetes severity, mild and serious T1DM patients were associated with a higher risk of HZ (adjusted HR = 2.26, 95% CI = 1.67-3.05; and adjusted HR = 5.08, 95% CI = 2.66-9.71, respectively) than subjects without T1DM.<br />Conclusion: Patients with T1DM are at a higher risk of HZ than those without T1DM.
