Abstract

Objectives
While the notified rates (per 100,000 persons, CIR) of new tuberculosis between 2016 and 2017 decreased in nationwide and 16 provinces, except Jeju Province, Korea. The aim was to compare CIRs of Jeju Province and nationwide by calendar years and age groups in order to interpret the increasing trend of CIR in Jeju Province.
Methods
The data source was the Integrated Diseases and Health Control System of the Korea Centers for Disease Control and Prevention. The selection criteria were the notified new cases as tuberculosis, who had the address as Jeju-do at diagnosis, between 2011 and 2018. The 95% confidence intervals (CI) of CIR was estimated based on Poisson distribution.
Results
There was not statistically significant difference of CIRs between nationwide and Jeju Province of 2011 and 2018, except 2016. Especially the CIR of group aged over 65 years in Jeju-do, 2016 was significantly lower compared to nationwide CIR.
Conclusions
Based on the results, the fact of increasing CIR from 2016 to 2017 in Jeju Province might be interpreted as an introduction of newly tuberculosis screening project rather than real increased CIRs.
