QuestionWhat is the relationship between the previously known risk factors and occurrence of carpal tunnel syndrome (CTS)?
FindingsIn this retrospective population-based cohort study that included 512,942 participants sampled from the Korean National Health Insurance System database, we determined the following known risk factors were related to the occurrence of CTS: the age of 40s, female, being overweight, diabetes, rheumatoid arthritis, gout, and Raynaud's syndrome. However, ESRD, hypothyroidism and smoking were not correlated with CTS occurrence.

3We identified the age of 40s, female, overweight, diabetes, rheumatoid arthritis, gout, and Raynaud's syndrome as risk factors for the occurrence of CTS.
Abstract ImportanceThere have been few large-scale studies that have included a risk factor analysis for CTS.No prior study has investigated and validated the relationship between the occurrence of CTS and known risk factors using nationwide health care database.
ObjectiveTo confirm the actual risk factors for CTS out of various known risk factors
DesignWe conducted this study using a retrospective cohort model based on the combined two databases of the Korean National Health Insurance System; the national periodic health

Main Outcomes and MeasuresDesired outcomes were the incidence rate of CTS in patients with various risk factors and the hazard ratios of risk factors affecting the disease's occurrence.
ResultsThe incidence of CTS was highest in patients in the age of 40s, in the moderate obesity group, in females, and in patients with diabetes mellitus (DM). The hazard ratio analysis revealed that the following risk factors were strongly related to the occurrence of CTS: age of 40s, female, obesity, DM, rheumatoid arthritis, gout, and Raynaud's syndrome. However, ESRD, hypothyroidism and smoking were not correlated with CTS occurrence.
Conclusions and RelevanceIn our large-scale cohort study, risk factors such as being in one's 40s, obesity, being female, suffering from DM, and rheumatoid arthritis were reaffirmed as those of CTS occurrence.
