Getting the latest healthcare news for you
Where you live as a young adult may quietly set the stage for heart disease decades down the road. A new study found that people exposed to adverse neighborhood social conditions — think limited food access, high crime, and low income — were more likely to develop coronary artery calcification by midlife, an early warning sign of cardiovascular disease. The effect was even stronger among Black participants.
Where you live matters — and not just for your commute. A new study published in Nature Communications found that adverse neighborhood social conditions in early adulthood are linked to a higher risk of coronary artery calcification (CAC) by midlife, a key early marker of cardiovascular disease. Northwestern Medicine researchers drew on data from the long-running CARDIA study and built a novel neighborhood social determinants of health index that combines socioeconomic status, food access, physical activity opportunities, and local crime rates.
Using machine learning and advanced statistical methods, the team found that participants exposed to more unfavorable neighborhood conditions in their 20s faced a measurably greater risk of CAC later in life — even after accounting for individual-level factors. The association was notably stronger among Black participants than white participants, pointing to compounding disparities in cardiovascular risk.
Key Takeaways
Why it matters: Cardiovascular disease is the leading cause of death in the U.S. and globally. This research shifts the lens from individual lifestyle choices to the broader environments that shape health — opening the door to more equitable, upstream interventions.
