  1. School-based interventions improve heart health in children with multiple cardiovascular disease risk factors.

    Article - En anglais

    Objective

    To determine the immediate effects of two types of elementary school-based interventions on children with multiple cardiovascular disease (CVD) risk factors.

    Design

    Randomized, controlled field trial.

    Setting

    Conducted in 18 randomly selected elementary schools across North Carolina.

    Study Participants

    Four hundred twenty-two children age 9 ± 0.8 years with at least two risk factors at baseline : low aerobic power and either high serum cholesterol or obesity.

    Intervention

    Both 8-week interventions consisted of a knowledge and attitude program and an adaptation of physical education.

    The classroom-based intervention was given by regular teachers to all children in the 3rd and 4th grades.

    The risk-based intervention was given in small groups only to children with identified risk factors.

    Children in the control group received usual teaching and physical education.

    Outcome Measures

    The primary outcome measure was cholesterol ; additional measures were blood pressure, body mass index, body fat, eating and activity habits, and health knowledge.

    Results

    Both interventions produced large reductions in cholesterol (-10.1 mg/dL and - 11.7 mg/dL) compared with a small drop (-2.3 mg/dL) in the controls.

    There was a trend for systolic blood pressure to increase less in both intervention groups than in the controls.

    Both intervention groups had a small reduction in body fat and higher health knowledge than the control group. (...)
