Lack of Association between Metabolic Syndrome and Depression in Korean Adults: Analysis Based on the 2016 and 2018 Korean National Health and Nutrition Examination Surveys

Abstract

Background: This study aims to investigate the relationship between metabolic syndrome and depression in Korean adults using data from the 2016 and 2018 Korean National Health and Nutrition Examination Surveys (KNHANES). Methods: The total number of participants in the 7th period 1st year (2016) and 3rd year (2018) surveys of KNHANES was 16142. This study was conducted with 10,722 subjects who met the diagnostic criteria for metabolic syndrome and responded to the Patient Health Questionnaire-9 (PHQ-9). Analysis of covariance was used to adjust the differences due to demographic factors, laboratory findings, and underlying diseases to understand the relationship between metabolic syndrome and PHQ-9 scores, if any. Results: The prevalence of metabolic syndrome was determined to be 25.6% in this study. The PHQ-9 scores with and without metabolic syndrome were 2.56 and 2.48, respectively, and there was no significant difference when the confounding variable was corrected (p=0.406). According to the analysis of each PHQ-9 item and metabolic syndrome, the results were not significant. Conclusion: In this cross-sectional study conducted in Korean adults, no significant correlation was found between metabolic syndrome and depression.
