Growing Republican mistrust in the healthcare system has widened health disparities between liberals and conservatives, according to a new study published in Nature Human Behaviour. The research identifies two distinct phases in the phenomenon: a gap that emerged in the 2010s tied to education polarization, followed by a second phase during the COVID-19 pandemic when social determinants of health could no longer explain the widening divide.
Education Divide and Deeper Distrust
During the 2010s, a pattern emerged as folks without a college degree moved politically to the right, while those with college degrees moved to the left. Since education is a strong predictor of health outcomes, this polarization initially drove some of the health gap. However, during the pandemic, the gap expanded beyond education differences. Survey data from 2024 shows that people on the right are less likely to trust, engage with, or use medicines to treat chronic illness relative to those on the left, even accounting for vaccination rate differences. This broader lack of trust in the medical system is contributing to worse health outcomes.
Specific Health Risks and Policy Implications
The research reveals particular vulnerabilities in cardiovascular health. Folks on the right have more hypertension than those on the left, and are now less likely to go to their doctor, less likely to trust their doctor, and less likely to think medicines for treating hypertension are safe and effective. Since cardiovascular disease is the number one cause of death in the United States, untreated hypertension poses serious risks both to individuals and public health. Anti-vaccination attitudes have also expanded beyond COVID-19 vaccines to long-established vaccines for dangerous conditions like measles, with more red states striking down vaccine mandates. As the health gap continues to grow, researchers emphasize the importance of tracking it more consistently to better understand the emerging public health challenge.
