Association Between Oral Health Status, Self-perceived Oral Health, and Depression.
Objectives: This study evaluated the association between oral health status, self-perception of oral health and depression in adults in Chile from the National Health Survey (NHS) 2016-2017. Methods: We conducted a cross-sectional study of secondary data from the NHS 2016-2017 in a subsample of 2,953 individuals over 18 years who had information regarding oral health, dental examination, mental health, and depressive symptoms. Expansion factors were respected, and associations were evaluated with logistic regression models, adjusted for sex, age and educational level and stratified by sex (Stata). Results: Individuals with removable dentures had an OR of 2.42 (95% CI 1.02 - 5.74; p: 0.045) of depression in the last 12 months. In women who frequently felt discomfort when eating because of their teeth or dentures, the OR of having been diagnosed with depression was 2.07 (95% CI: 1.33 - 3.24; p: 0.001), and of having received treatment for this pathology, an OR of 1.93 (95% CI: 1.23 - 3.03; p: 0.004). Men with caries in the upper teeth had an OR of 1.36 (95% CI: 1.15 - 1.61; p: <0.001) of depression in the last 12 months. Conclusions: Oral health and self-perception are significantly associated with depression and depressive symptoms, evidencing a modification of the effect of the sex variable in adults in Chile.
