Evaluation of a school-site cardiovascular risk factor screening intervention

Area of Science:

• Public Health
• Pediatric Health
• Health Education

Background:

• Previous studies confirmed the feasibility of school-based cardiovascular risk factor screening.
• The ability of these programs to detect high-risk children and parents is established.
• Limited data exists on the cognitive and behavioral effects of such school programs.

Purpose of the Study:

• To evaluate the cognitive and behavioral impact of school-based cardiovascular risk factor screening.
• To assess changes in health knowledge, attitudes, and behaviors among students and parents.
• To determine if school-based screening can be an effective adjunct to traditional health education.

Main Methods:

• A quasi-experimental design involving eight Michigan elementary schools.
• Intervention group: Four schools received cardiovascular risk factor screening twice (1989-1990).
• Comparison group: Four schools served as controls; all schools implemented the Michigan Model Comprehensive School Health Education Program.

Main Results:

• Significant improvements in health knowledge and attitudes regarding nutrition and disease detection were observed in students (n=1,166) and parents (n=514).
• Students reported decreased intake of high-fat foods.
• Participating parents were more likely to report cholesterol and blood pressure testing.

Conclusions:

• School-based cardiovascular risk factor screening positively influences student and parent knowledge, attitudes, and behaviors.
• These programs show potential as an effective addition to traditional health education curricula.
• School-based screening offers a viable method for early disease detection in children and families.
