Abstract 15499: Maintenance of Ideal Cardiovascular Health Over 20 Years and Its Impact on Health Related Quality of Life: The Coronary Artery Risk Development in Young Adults (CARDIA) Study
Background: Ideal CV Health during middle age has been associated with reduced cardiovascular disease, health care costs and improved longevity. It is unknown whether ideal CV health in younger ages and long-term risk factor changes are associated with quality of life in middle age. Our aim was to determine the association between maintenance of Ideal CV Health over 20 years and health related quality of life as measured by the SF-12.
Methods: CARDIA participants aged 18-30 at baseline who attended exams at years 0, 7, and 20 and had no history of cardiovascular disease were included in this analysis. Ideal health was defined as untreated BP <120/<80, untreated cholesterol 1 yr ago), ideal diet (top 40% of diet score), met physical activity guidelines and BMI <25. We created groups depending on their ideal CV health status (yes/no) at years 0, 7 and year 20. Linear regression models were used to examine the association between the risk groups and the SF-12 physical and mental scores at year 25 adjusting for age, race, gender, education and income.
Results: This analysis included 2,121 participants, 47% were in Ideal health at year 0 and 17.2% remained in Ideal health throughout years 0, 7 and 20. Those who maintained Ideal health were more likely to White (86% vs 53%), female (66% vs 54%) and had a higher level of education. After adjustment, participants in Ideal health at baseline had significantly higher physical component scale scores (52.3 [51.8-52.8] vs 49.6 [49.1-50.0]) and mental component scale scores (52.3 [51.8-52.8] vs 49.6 [49.1-50.0]) as compared to those not in Ideal health at baseline. Differences in SF-12 scores were even larger across patterns of ideal CV health maintenance over the 20-years of follow-up (figure), especially for physical functioning.
Conclusion: The presence and maintenance of Ideal CV health is associated with an improved quality of life in middle-age, an important patient-reported outcome.
