Northwestern Medicine study links early adulthood neighborhood conditions to heart health

A study published in Nature Communications by researchers at Northwestern Medicine indicates that the social conditions of a person's neighborhood during early adulthood can impact heart health decades later.

Using data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, researchers developed a new index to evaluate multiple social determinants of health simultaneously. This index includes socioeconomic conditions, access to food, opportunities for physical activity, and local crime rates.

The findings show that individuals exposed to unfavorable neighborhood conditions in their youth have a higher likelihood of developing coronary artery calcification (CAC) by midlife, which is a key marker for early cardiovascular disease. The study noted that this association was more pronounced among Black participants compared to White participants. Lead author Lifang Hou stated that the research shifts the focus from individual lifestyle factors to a more comprehensive understanding of how neighborhood context shapes long-term health.
