Early adult neighborhood conditions tied to midlife cardiovascular risks, study finds

Northwestern Medicine researchers found that unfavorable neighborhood factors in a person's 20s are linked to higher rates of coronary artery calcification decades later.

The short version

  • A study published in Nature Communications found that living in disadvantaged neighborhoods during young adulthood is linked to a higher risk of midlife coronary artery calcification.
  • Researchers analyzed long-term data from the CARDIA study using a composite index assessing local socioeconomic factors, crime rates, food access, and recreation opportunities.
  • The observed link between adverse early neighborhood conditions and calcification was stronger among Black participants than white participants.
  • Scientists plan to test the index across wider populations and examine whether these early exposures also correspond to future heart attacks or heart failure.

Key facts

  • Northwestern Medicine researchers analyzed data from the Coronary Artery Risk Development in Young Adults (CARDIA) study to evaluate how early-life neighborhood environments affect long-term heart health.[ScienceDaily]
  • The research team constructed a neighborhood social determinants index incorporating local crime rates, food access, socioeconomic conditions, and opportunities for physical activity.[ScienceDaily]
  • Exposure to unfavorable neighborhood conditions in early adulthood was associated with an increased likelihood of developing midlife coronary artery calcification, an early marker of cardiovascular disease.[ScienceDaily]
  • The correlation between adverse early neighborhood conditions and coronary artery calcification was stronger among Black participants than among white participants.[ScienceDaily]

What remains uncertain

  • It remains to be determined whether the identified neighborhood factors correlate directly with clinical cardiovascular events like heart attacks and heart failure, or how neighborhood transitions over time alter long-term risk.[ScienceDaily]
  • The predictive index has yet to be validated across different demographic populations and broader geographic regions.[ScienceDaily]
