How was I selected?

In 1985-86, the Coronary Artery Risk Development in Young Adults (CARDIA) study enrolled 5,115 participants to reflect the population of four U.S. communities: Birmingham, Ala.; Minneapolis, Minn.; Chicago, Ill.; and Oakland, Calif. At the Birmingham, Minneapolis, and Chicago sites, participants were recruited by random-digit dialing from total communities or specific census tracts. In Oakland, participants were randomly selected from a health-care plan. Participants were balanced for gender, age (18-24 years and 25-30 years) race (black and white), and education (high school or less education and greater than high school education).

How am I helping?

Because of you, scientists are making great strides in the prevention of heart disease. CARDIA gives researchers a unique look at the ways heart disease risk changes over time during young adulthood. Study results are also shedding new light on:

  • Racial inequities in heart disease risk factors and outcomes.
  • The role of diet, physical activity, and fitness in body composition, nonalcoholic fatty liver disease, diabetes, inflammation, lipids, blood pressure.
  • The role of psychosocial factors (e.g., stress, discrimination, social support) on health.
  • The social and environmental determinants of health, including health-care access,
  • The influence of genetics on health,
  • Lung function changes and abnormalities, and
  • Women’s health, with a special focus on pregnancy-related issues.

Thank you for making these medical advances possible through your participation in CARDIA.
