    Objective: Favorable cardiovascular health is associated with greater longevity free of cardiovascular disease. Although the prevalence of cardiovascular health decreases with age, less is known about protective factors that promote and preserve it over time. We investigated whether optimism was associated with better cardiovascular health over a 10-year period. Methods: Participants included 3188 Black and White men and women from the Coronary Artery Risk Development in Young Adults study. Self-reported optimism was assessed in 2000 (this study's baseline) with the revised Life Orientation Test. Favorable cardiovascular health was defined by healthy status on five components of cardiovascular functioning that were repeatedly assessed through 2010 either clinically or via self-report (blood pressure, lipids, body mass index, diabetes, and smoking status). Linear mixed-effects models examined whether optimism predicted cardiovascular health over time, adjusting for covariates such as sociodemographic characteristics, health behaviors, health status, and depression diagnosis. Results: In models adjusting for sociodemographic characteristics, optimism was associated with better cardiovascular health across all time points (β = 0.08, 95% confidence interval = 0.04-0.11, p ≤ .001) but not with rate of change in cardiovascular health. Findings were similar when adjusting for additional covariates. Optimism did not interact significantly with race (p = .85) but did with sex, such that associations seemed stronger for women than for men (p = .03). Conclusions: Optimism may contribute to establishing future patterns of cardiovascular health in adulthood, but other factors may be more strongly related to how slowly or quickly cardiovascular health deteriorates over time.

    Positive emotions and favorable cardiovascular health: A 20-year longitudinal study
    (Elsevier, 2020-07) Boehm, Julia K.; Chen, Ying; Qureshi, Farah; Soo, Jackie; Umukoro, Peter; Hernandez, Rosalba; Lloyd-Jones, Donald; Kubzansky, Laura D.; Medicine, School of Medicine
    No studies have examined whether positive emotions lead to favorable cardiovascular health (CVH) early in the lifespan, before cardiovascular disease is diagnosed. Moreover, the direction of the association has not been thoroughly investigated. Among younger adults, we investigated whether baseline positive emotions were associated with better CVH over 20 years. We also considered whether baseline CVH was associated with subsequent positive emotions during the same period. Participants included 4196 Black and White men and women from the Coronary Artery Risk Development in Young Adults Study. Positive emotions and cardiovascular-related parameters were each assessed in 1990 (this study's baseline), with repeated assessment through 2010. CVH was defined by blood pressure, lipids, body mass index, diabetes, and smoking status. Primary analyses used linear mixed effects models adjusting for potential confounders; secondary analyses stratified by race and sex. Controlling for sociodemographic factors, greater baseline positive emotions were associated with better CVH across time (β = 0.03, 95% confidence interval = 0.007-0.06). However, positive emotions were unrelated to rate of change in CVH across time. Baseline CVH was also associated with greater average positive emotions across time (β = 0.09, 95% confidence interval = 0.02-0.15), but not rate of change. Positive emotions' association with CVH was stronger for women than men, but race did not modify associations. Positive emotions in early to middle adulthood were associated with better CVH across several decades. Baseline CVH was also associated with greater positive emotions during follow-up. Future research may be able to disentangle these relationships by assessing positive emotions and CVH earlier in life.
