Abstract

Background: Tuberculosis is an infectious disease influenced by social factors rather than a simple infectious disease. In this study, we investigated the relationship between tuberculosis rates and socioeconomic status.

Methods: This study was conducted using data of the 49,483 participants of the Korean National Health and Nutrition Examination Survey (KNHANES) VI-VIII (2013-2021). The relationships between tuberculosis rates and the quartiles of monthly household income and education level were examined using a multivariate logistic regression analysis.

Results: The KNHANES data revealed that the prevalence of tuberculosis as substantially related to monthly household income (odds ratio [OR], 6.0; 95% confidence interval [CI], 1.1-32.0 for lowest vs. highest incomes) and education level (OR, 3.8; 95% CI, 1.2-12.0 for 10-12 years vs. ≥13 years; OR, 4.1; 95% CI, 1.2-14.8 for ≤ 6 years vs. ≥13 years). Furthermore, current tuberculosis treatment was significantly related to monthly household income and education level.

Conclusion: There were substantial correlations between tuberculosis rates and socioeconomic status in South Korea.
