A recent study published in The Lancet Regional Health—Americas sheds light on the growing disparities in cardiovascular health in the United States, with wealth and education playing a significant role in heart disease risk.
The research, led by Salma Abdalla, MBBS, DrPH, an assistant professor of public health at Washington University in St. Louis, reveals that high-income, college-educated individuals in the top 20% of the population have significantly lower rates of cardiovascular disease compared to the rest of the population. These disparities have widened over the past two decades, highlighting the impact of income and education on heart health.
Despite cardiovascular disease remaining the leading cause of illness and death in the U.S., the study shows that the remaining 80% of the population faces higher risks, reflecting the nation’s growing income gap. The U.S. spends more on healthcare per person than any other high-income country, yet outcomes continue to lag behind, especially for those with lower incomes and less education. Life expectancy for the wealthiest 1% of Americans is now 10 years higher than for the poorest 1%, showcasing the worsening health inequalities.
The study analyzed data from nearly 50,000 adults over a 20-year period, categorizing participants based on income and education levels. The prevalence of major cardiovascular conditions such as congestive heart failure, angina, heart attack, and stroke were examined, revealing stark disparities between high-income, college-educated individuals and their lower-income, less educated counterparts.
Even after adjusting for demographic and health markers like BMI, blood pressure, and cholesterol levels, the study found that low-income, non-college graduates had significantly higher odds of cardiovascular conditions compared to wealthier, college-educated individuals. Income and education consistently correlated with better heart health, highlighting the complex role these factors play in shaping cardiovascular risk.
The findings suggest that the accumulation of economic and educational advantages over time leads to better health outcomes, rather than any single factor alone. Addressing cardiovascular disease requires more than just expanding healthcare access; it also involves policies that promote economic opportunity and educational equity to break down structural barriers.
Senior author Sandro Galea, MD, DrPh, the Dean of the School of Public Health at Washington University, emphasized the need for action to address the widening health disparities in the U.S. The study underscores the importance of tackling the root causes of health inequalities, including economic opportunity, education, and access to resources that support long-term health.
In conclusion, the study highlights the urgent need for policies that address the social determinants of health to reduce disparities in cardiovascular disease and improve public health outcomes in the U.S.
