A study published in JAMA Cardiology on March 31, 2025, analyzed data from more than 27,000 adults in the United States and revealed a worrying reality: residents of rural areas suffer more from heart disease than those living in urban centers.

Contrary to popular belief, the main driver isn’t limited access to doctors or hospitals. The analysis indicates that social conditions—such as poverty, food access, and educational attainment—weigh even more heavily in these disparities.

Young Rural Adults Face Even Greater Risks

Participants were divided into three groups: rural areas (14 %), small to midsize metropolitan areas (54.8 %), and large urban areas (31.2 %). Results show that adults in rural zones have higher rates of hypertension, high cholesterol, obesity, diabetes, and heart disease compared to urban residents. For example, the prevalence of hypertension in rural areas was 37.1 % versus 30.9 % in urban areas—a 20 % higher relative risk.

The study also pointed out meaningful inequalities among individuals aged 20 to 39. In this age group, the risk of hypertension was 44 % higher in rural zones, while the risk of obesity was 54 % greater. The most alarming finding was diabetes: Young rural adults faced a 2.5 times higher risk than their urban peers, indicating these conditions are affecting populations at ever-earlier ages.

Social Factors Explain Much of the Disparities

Even after adjustments that accounted for healthcare access, such as having health insurance or a regular doctor, the differences persisted. The same was true for behavioral factors like smoking or physical inactivity, which also failed to explain the results.

When researchers factored in social determinants, however, they observed a dramatic reduction in disparities. Issues such as educational level, food insecurity, poverty, and home ownership proved decisive. Once these aspects were considered, differences in hypertension, diabetes, and heart disease nearly vanished. Obesity remained the only condition with a residual gap, albeit much reduced.

Pathways to Improving Health in Rural Communities

The study emphasizes that improving healthcare access, while significant, isn’t sufficient. Long-term structural investments are needed, focusing on:

• Quality education

• Poverty reduction

• Ensuring food security

Such measures guarantee that rural populations have the same health opportunities as city dwellers. Addressing the social roots of these inequalities is paramount; otherwise, cardiovascular problems will continue to affect millions of people in America's heartland.
