    Abstract:
    BACKGROUND: Studies focusing on the association between anxiety/depressive symptoms and accelerated subclinical atherosclerosis have yielded mixed results. Our aim is to examine associations between anxiety/depressive symptoms, common mental disorder (CMD), major depression disorder (MDD) or generalized anxiety disorder (GAD) and carotid intima-media thickness (CIMT) in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort baseline. METHODS: The ELSA-Brasil baseline assessment included CIMT measurements and the Clinical Interview Schedule - Revised (CIS-R), a validated questionnaire for anxiety/depressive symptoms/diagnoses. We analyzed participants without previous coronary heart disease or stroke, and with high-quality CIMT images. We built regression models to determine whether the CIS-R score, CMD, MDD or GAD were associated with maximal CIMT levels. RESULTS: The study sample comprised 9744 participants. We found that individuals with higher CIS-R scores (Odds ratio for one standard deviation increase [OR]:1.12; 95% confidence interval [95%CI]:1.06-1.19), CMD (OR:1.22; 95%CI:1.07-1.38) and GAD (OR:1.19; 95%CI:1.01-1.41) had significantly higher odds of being classified in the highest age, sex and race-specific CIMT quartile. In the linear models, after adjustment for traditional cardiovascular risk factors, higher CIS-R scores (β:0.005; P = 0.010) and GAD (β:0.010; P = 0.049) were independently associated with CIMT values. CONCLUSION: Individuals with more symptoms of anxiety and/or depression, or diagnoses of CMD or GAD, had higher CIMT values, compared to peers of same age, sex and race. CIS-R scores and GAD were independently associated with higher CIMT values. These results suggest an association between anxiety/depressive symptoms (and, most notably, GAD) and accelerated subclinical atherosclerosis.
