Lijing L. Yan, research assistant professor of preventive medicine at Northwestern University Feinberg School of Medicine and Guanghua School of Management, Peking University, Beijing, was first author on the study.
Many studies have documented that education is inversely associated with a wide array of clinical disease outcomes and death, and the relationship between education and cardiovascular disease and coronary heart disease in particular is among the most consistent and pronounced. But little is known about the relationship between education and subclinical disease (an illness that stays below the surface of clinical detection).
Yan and colleagues analyzed data from the Coronary Artery Risk Development in Young Adults (CARDIA) study, which included 2,913 participants (45 percent black; 54 percent women). The participants, who were 18 to 30 years old at the beginning of the study in 1985-1986, were recruited from Chicago, Minneapolis, Birmingham, Ala., and Oakland, Calif.
There were 128 study participants with less than a high school diploma; 498 were high school graduates; 902 had some college; 764 were college graduates; and 621 had more than a college education.
At year 15 of the study, the overall prevalence of coronary artery calcium (CAC) among eligible participants was a little over 9 percent.
"For the biracial young adult and early middle-aged cohort (aged 33 to 45 years) with a wide spectrum of educational levels, educational level was inversely associated with prevalence of CAC in a graded dose-response fashion, with particularly higher prevalence for individuals with less than a high school degree," the autho
