IM. Association between ideal cardiovascular health and depression incidence: a longitudinal analysis of ELSA-Brasil.Objective: We investigated whether ideal cardiovascular health (ICH), a metric proposed by the American Heart Association, predicts depression development. Methods: Cohort analysis from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Adults with no current depression and other common mental disorders, cardiovascular diseases, and antidepressant drug use at baseline had their ICH (composite score of smoking, dietary habits, body mass index, blood pressure, fasting glucose, cholesterol, and physical activity) assessed and classified into poor, intermediate, and optimal. Depression was assessed using the Clinical Interview Schedule-Revised (CIS-R). Poisson regression models, adjusted for sociodemographic factors and alcohol consumption, were employed. Stratified analyses were performed for age and sex. Results: We included 9214 participants (mean age 52 AE 9 years, 48.6% women). Overall depression incidence at 3.8-year follow-up was 1.5%. Intermediate and poor ICH significantly increased the risk rate (RR) of developing depression (2.48 [95%CI 1.06-5.78] and 3 [1.28-7.03], respectively) at a 3.8-year follow-up. Higher ICH scores decreased the rate of depression development (RR = 0.84 [0.73-0.96] per metric). Stratified analyses were significant for women and adults < 55 years old. Conclusions: Poor cardiovascular health tripled depression risk at follow-up in otherwise healthy adults. Ameliorating cardiovascular health might decrease depression risk development.
Significant outcomes• Poor cardiovascular health predicts depression incidence in subjects free of mental and cardiovascular disorders.• These effects are more pronounced in women and in subjects younger than 55 years old. • Decreasing cardiovascular risk can impact in both clinical and mental outcomes.
Limitations• The follow-up period was relatively small (3.8 years).• Other common mental disorders were not examined.
