Abstract

PURPOSE
The authors hypothesized that increases in socioeconomic status (SES) have enabled patients to access medical services more frequently, resulting in the increased detection of small thyroid cancers. This retrospective cohort study was designed to analyze the correlation between thyroid cancer incidence and SES using a 10-year sample cohort database. METHOD: Sample cohort database between January 2004 and December 2013 with 1,000,000 cases for each year was enrolled in this study. Thyroid cancer incidence was analyzed by sex and by age. Public health insurance payment was used to reflect SES. The correlation between SES and thyroid cancer incidence was analyzed, and medical checkups done under government programs based on SES were analyzed.
RESULTS
When the results were considered according to SES, the high SES group showed a higher incidence of thyroid cancer than low SES group. Also, participation in government-supported health checkup programs was higher in the high SES group higher in the high SES group compared to low SES group.
CONCLUSION
SES and incidence of thyroid cancer have positive correlation.
