Cardiovascular risk stability: from grade school to high school
Summary
Longitudinal data show school-based cardiovascular risk reduction programs yield stable obesity and cholesterol risks. However, heart rate recovery and blood pressure changed significantly over time in students.
Area of Science:
- Public Health
- Cardiovascular Health
- Pediatric Health
Background:
- School-based cardiovascular risk reduction programs have proliferated, yet robust longitudinal data on their long-term effectiveness remain scarce.
- Evaluating the sustained impact of these interventions is crucial for public health strategies targeting childhood cardiovascular disease prevention.
Purpose of the Study:
- To assess the stability of cardiovascular risk factors from elementary to high school.
- To examine changes in cardiovascular risk profiles over time.
- To identify gender-specific differences in cardiovascular risk trajectories.
Main Methods:
- A longitudinal study design was employed, following 195 students from elementary school (sixth grade) into high school.
- Participants had previously engaged in a school-based cardiovascular risk reduction program.
- Data were collected three to six years after program completion to provide a longitudinal perspective.
Main Results:
- Risk factors for obesity and high cholesterol remained stable over the follow-up period.
- Significant improvements were observed in heart rate recovery and blood pressure.
- Elevated cholesterol levels were identified as a specific risk factor in female students.
Conclusions:
- School-based programs demonstrate sustained effects on obesity and cholesterol risk, with notable improvements in physiological markers like heart rate recovery and blood pressure.
- Targeted interventions may be necessary to address gender-specific risks, such as elevated cholesterol in females.
- Findings underscore the importance of long-term follow-up in evaluating cardiovascular health initiatives in youth.
