The study has been extended through July 2005 and uses data and analyses from the Chicago Heart Association Detection Project in Industry cohort. The study focuses on three specific aims: factors influencing coronary heart disease and cardiovascular disease risk long-term in young adult women (ages 18-39 at baseline); factors influencing coronary heart disease and cardiovascular disease risk long-term in young adult and middle-aged African American men and women; and the impact of baseline "low risk" status on long-term mortality from coronary heart disease, cardiovascular disease, non-cardiovascular disease, and all causes in young adult women (ages 18-39), including African-American and white women.
