Abstract
This study was designed to create, implement, and test a school-based multiple risk factor reduction program for high school students. All tenth graders in four senior high schools (N = 1447) from two school districts participated in the study. Within each district, one school was assigned at random to receive a special 20-session CVD risk reduction intervention and one school served as a control. The schools were matched for size and distribution of racial groups before randomization. At a two-month follow-up, knowledge gains were significantly greater for students in the treatment group on each of the risk factor domains tested: nutrition/diet (p less than 0.0001), physical activity (p less than 0.0001), and cigarette smoking (p less than 0.0001). Compared to controls, a higher proportion of those in the treatment group who were not exercising regularly at baseline, reported regular exercise at follow-up (p less than 0.0003). Almost twice as many baseline experimental smokers in the treatment group reported quitting at follow-up while only 5.6% of baseline experimental smokers in the treatment group graduated to regular smoking compared to 10.3% in the control group (p = 0.009). Students in the treatment group were more likely to report that they would choose heart healthy snack items (p less than 0.0001). Beneficial treatment effects were observed for resting heart rate (p less than 0.0001), BMI (p = 0.05), triceps skinfold thickness (p = 0.003), and subscapular skinfold thickness (p = 0.01). The results suggest that it is feasible to provide CVD risk reduction training to a large segment of the population through school-based primary prevention approaches.
