Abstract 11389: Prevalence and Trends of Ideal Cardiovascular Health in 18 Countries: A Pooled Analysis of 68 Nationally Representative Surveys

Abstract

Introduction: Increasing the prevalence of the ideal cardiovascular health (CVH) phenotype over the coming decades would likely result in dramatic improvements in healthy longevity and reductions in healthcare costs. Therefore, it is of paramount importance to understand the global prevalence and trends of the ideal CVH behaviors and factors for monitoring progress and providing evidence to support policy efforts. Hypothesis: We aim to describe the prevalence of CVH for the AHA defined metrics of tobacco use, body mass index, total cholesterol, blood pressure and glucose levels, and estimate its trends worldwide. Methods: We used data from people aged > 20 years who participated in 68 national health examination surveys from 1983 to 2017 in 18 countries: Australia, Czech Republic, Denmark, Germany, Greece, Ireland, Italy, Malaysia, Mexico, Poland, Seychelles, Slovakia, South Korea, Spain, Sweden, Turkey, the UK, and the USA. We calculated age-standardized prevalence of ideal CVH (no current smoking, BMI < 25 kg/m2, untreated TC < 200 mg/dL, untreated BP < 120 / < 80 mmHg, and absence of diabetes mellitus). Additionally, we examined the trends of the ideal CVH for countries that had at least two individual-level national surveys in two different decades (2000-2009 vs 2010-2019). Results: With the exception of Australia and South Korea, age-standardized prevalence of idea CVH was lower than 10% in women and lower than 5% in men across all countries. Older individuals had a lower prevalence of Ideal CVH than younger ones. Those over 65 years of age had a prevalence almost equal to zero. In ages 35-64 years, ideal CVH prevalence ranged from 3.6% to 25.4% among women, and from 0.6% to 7.1% among men. For the 10 countries where trends were estimated by age-sex groups, ideal CVH prevalence did not change or declined in the selected middle-income countries and increased in the selected high-income countries except for South Korea, where it plateaued for men and declined for women. Conclusions: Prevalence of ideal CVH worldwide is low and is declining for adults in middle-income countries in recent decades.
