Sex-based Association between Depression and Metabolic Syndrome in Korean Middle-aged and Older Adults.

OBJECTIVES

This study aimed to identify the sex-based association between depression and the development of metabolic syndrome (Mets) among middle-aged and older Korean adults.

METHODS

A cross-sectional design was used for the secondary analysis of the 2010-2014 Korean National Health and Nutrition Examination Survey. Data from 1,938 men and 2,404 women were analyzed. Mets was defined in accordance with the criteria used for clinical diagnosis. Depression was assessed with a question about having clinical depression. The association between depression and the development of Mets with or without adjustment for covariates was identified by conducting logistic regression analysis on weighted data using a complex sample procedure.

RESULTS

More women than men had depression. Before covariate adjustment, depression was significantly associated with the development of Mets among women (odds ratio [OR], 1.586; 95% confidence interval [CI], 1.152-2.183) and with a higher triglyceride level among men (OR, 1.679; 95% CI, 1.001-2.818). After covariate adjustment; depression was significantly associated with higher waist circumference among women (adjusted OR [AOR], 1.532; 95% CI, 1.046-2.245) and higher triglyceride level (AOR, 1.511; 95% CI, 1.029-2.219) than was Mets. Conversely, depression did not have significant effects on the development of Mets among men.

CONCLUSION

Depression was associated with the development of Mets among middle-aged and older Korean women. Healthcare providers in communities should assess women with depression for the presence of Mets components. Interventions for relieving depressive symptoms should also be provided to women at risk for Mets.
