The Association between Pulmonary Function and Metabolic Syndrome in Koreans: A Cross-Sectional Study

Background: This study was performed to establish the relationship between these diseases by analysing the prevalence of metabolic syndrome and its link to pulmonary dysfunction. Material and Methods: This study obtained data from the 6th Korea National Health and Nutrition Examination Survey (KNHANES, 2013-2015), a cross-sectional and nationally representative survey conducted by the Korean Centres for Diseases Control and Prevention. Results: Of the 8,156 participants included in this study, the prevalence rate of restrictive pattern in the subjects of this study was 8.71% and 14.39% in the obstructive pattern. The prevalence of metabolic syndrome was 29.38%. The results of the relationship between pulmonary function and metabolic syndrome through logistic regression analysis showed a significant difference in the restrictive pattern, but no difference in the obstructive pattern, in odds ratio corrected for variables that could affect metabolic syndrome and pulmonary dysfunction (restrictive: OR 1.308, 95% CI 1.024-1.671; obstructive: OR 0.928, 95% CI 0.739-1.166). Conclusion: The conclusion of this study found that, rather than obstructive pattern, the restrictive pattern was highly correlated with metabolic syndrome regardless of the confounding variables or risk factors of various metabolic syndromes that could be mediated.

Automated summary

This study found a strong correlation between restrictive pulmonary function pattern and metabolic syndrome, while no significant correlation was observed with obstructive pulmonary pattern.
