Summary

A school-based program significantly improved cardiovascular disease (CVD) risk factors in high school students. The intervention led to better knowledge, increased physical activity, reduced smoking, and healthier food choices.

Area of Science:

  • Public Health
  • Preventive Medicine
  • Health Education

Background:

  • Cardiovascular disease (CVD) risk factors often originate in adolescence.
  • School-based interventions offer a viable platform for primary prevention.
  • Targeting multiple risk factors simultaneously can enhance program effectiveness.

Purpose of the Study:

  • To develop, implement, and evaluate a school-based multiple risk factor reduction program for high school students.
  • To assess the program's impact on knowledge, behaviors, and physiological measures related to CVD risk.
  • To determine the feasibility of school-based primary prevention for CVD risk reduction.

Main Methods:

  • A 20-session intervention program targeting nutrition, physical activity, and smoking cessation was delivered to tenth graders in four high schools.

  • Schools were matched by size and racial distribution, with one school per district randomly assigned to the intervention or control group.
  • Data were collected at baseline and a two-month follow-up, including knowledge assessments, self-reported behaviors, and physiological measurements (resting heart rate, BMI, skinfold thickness).

    • Main Results:

    • Students in the treatment group showed significantly greater knowledge gains in nutrition, physical activity, and smoking cessation (p < 0.0001).
    • The intervention group demonstrated increased regular exercise (p < 0.0003), higher rates of smoking cessation (p = 0.009), and a greater likelihood of choosing heart-healthy snacks (p < 0.0001).
    • Beneficial effects were observed in resting heart rate (p < 0.0001), BMI (p = 0.05), and skinfold thickness measurements (p = 0.003, p = 0.01).

    Conclusions:

    • School-based multiple risk factor reduction programs are feasible and effective for improving CVD risk profiles in adolescents.
    • This intervention successfully enhanced health knowledge and promoted healthier behaviors among high school students.
    • Primary prevention through school settings can significantly impact long-term cardiovascular health.
