  1. Reducing Obesity via a school-based interdisciplinary intervention among youth : Planet Health.

    Article - En anglais


    To evaluate the impact of a school-based health behavior intervention known as Planet Health on obesity among boys and girls in grades 6 to 8. Design : Randomized, controlled field trial with 5 intervention and 5 control schools.

    Outcomes were assessed using preintervention (fall 1995) and follow-up measures (spring 1997), including prevalence, incidence, and remission of obesity.


    A group of 1295 ethnically diverse grade 6 and 7 students from public schools in 4 Massachusetts communities.


    Students participated in a school-based interdisciplinary intervention over 2 school years.

    Planet Health sessions were included within existing curricula using classroom teachers in 4 major subjects and physical education.

    Sessions focused on decreasing television viewing, decreasing consumption of high-fat foods, increasing fruit and vegetable intake, and increasing moderate and vigorous physical activity.

    Main Outcome Measures 

    Obesity was defined as a composite indicator based on both a body mass index and a triceps skinfold value greater than or equal to age-and sex-specific 85th percentiles.

    Because schools were randomized, rather than students, the generalized estimating equation method was used to adjust for individual-level covariates under cluster randomization.


    The prevalence of obesity among girls in intervention schools was reduced compared with controls, controlling for baseline obesity (odds ratio, 0. (...)
