ABSTRACT

Objectives: To examine the association between chewing problems and depression in a representative sample of Korean adults. Methods: This study included 4,887 participants aged 19 years or older. Chewing problems were self-reported. Depression was measured using the PHQ-9 scale, which scored the frequency of symptoms over the last two weeks. Logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence intervals (CI). Results: There was a significant positive correlation between chewing problems and depression. Compared to those without chewing problems, participants with chewing problems had a 1.62 times higher risk of mild depression (OR=1.62; 95% CI:1.29–2.05), a 2.27 times higher risk of moderate depression (OR=2.27; 95% CI:1.52–3.38), and a 6.15 times higher risk of severe depression (OR=6.15; 95% CI:2.31–16.37). Conclusions: Results of this study indicate a significant association between chewing problems and depression. In addition, chewing problems were found to have a stronger relationship with higher severity levels of depression.
