Abstract
We conducted a study of the effectiveness of an educational intervention designed to modify risk factors associated with coronary heart disease among 3388 children in 37 schools in two demographically dissimilar areas (the Bronx and Westchester County) in and around New York City. Schools within each area were randomly assigned to either intervention or nonintervention groups. In schools targeted for intervention, children in the fourth through eighth grades were taught a teacher-delivered curriculum focusing on diet, physical activity, and cigarette smoking. Risk-factor levels were measured in all schools at base line and at four follow-up points. A total of 1769 of the children qualified for analysis of the intervention effect.
