A public health vs a risk-based intervention to improve cardiovascular health in elementary school children : The cardiovascular health in children study.
This study sought to determine the population effects of both classroom-based and risk-based interventions designed to reduce cardiovascular disease risk factors in children.
Elemenary school children (n=2109 ; age range 7-12 years) were randomized by school to a classroom-based intervention for all third and fourth graders, a risk-based intervention only for those with 1 or more cardiovascular disease risk factors, or a control group.
The 8-week interventions involved both knowledge-attitude and physical activity components.
School-level analyses showed that physical activity in the risk-based group and posttest knowledge in the classroom-based groups were significantly higher than in the control group.
With regard to trends shown by individual-level analyses, cholesterol dropped more in the classroom-based than in the control group, and skinfold thickness decreased 2,9% in the classroom-based group and 3.2% in the risk-based group (as compared with a 1.1% increase in the control group).
Both classroom-based and risk-based interventions had positive effects on physical activity and knowledge, with trends toward reduced body fat and cholesterol.
However, the classroom-based approach was easier to implement and evidenced stronger results than the risk-based intervention.
