Abstract 14705: The Association of Optimism and Pessimism With Cardiovascular Health: Results From the Multi-Ethnic Study of Atherosclerosis (MESA)
Background: Research suggests that an individual’s life-orientation, appraised by examining levels of optimism and pessimism, can affect cardiac-related health. This study aimed to examine cross-sectional associations of optimism and pessimism with cardiovascular health (CVH).
Methods: This study used data collected from adults aged 46-87 who participated in the Multi-Ethnic Study of Atherosclerosis (MESA) (n=5,193) during the first follow-up visit (2002-2004). Dispositional optimism and pessimism were captured using the Life-Orientation Test--Revised (LOT-R). American Heart Association (AHA) standards were considered when classifying the seven CVH metrics--diet, body mass index, physical activity, serum cholesterol, blood pressure, fasting glucose, and smoking status--into categories of poor, intermediate, and ideal, with an associated point allocation ranging from 0 (poor) to 2 (ideal). An overall CVH score was calculated ranging from 0 to 14, with CVH scores ≥12 interpreted as indicative of ideal CVH. Life-orientation’s association with ideal cardiovascular health was evaluated using logistic regression to estimate adjusted odds ratios. The 6-item LOT-R was analyzed as a composite and separately by the optimism and pessimism subscales.
Results: Among 5,193 MESA participants with complete data, 6% were categorized as having ideal CVH. When using the full 6-item LOT-R measure, those in the highest optimism quartiles had 48% higher odds of having ideal cardiovascular health when compared to those with the lowest levels of optimism in fully adjusted models (Table 1). Additionally, compared to the least pessimistic subgroup, participants in the highest quartile of pessimism had 43% lower odds of having ideal CVH. Less robust results were seen for the optimism subscale after adjustment.
Conclusion: The current study offers preliminary evidence for an association between life-orientation and CVH.
