Trial summary

Childhood obesity is a major public health threat. Physical activity and healthy eating contribute to the maintenance of healthy weights. Individually oriented behaviour change programs may not be able to overcome the influence of what has been called an obesogenic environment. Read more about this study

About this study

Official title: Evaluating the Effectiveness of the Dissemination of Action Schools! BC: A Socio-ecological Intervention to Increase Physical Activity and Healthy Eating in School Children

Childhood obesity is a major public health threat. Physical activity and healthy eating contribute to the maintenance of healthy weights. Individually oriented behaviour change programs may not be able to overcome the influence of what has been called an obesogenic environment. Action Schools! BC (AS! BC) used a socio-ecological approach to enhance opportunities for physical activity and healthy eating in elementary schools and created systemic change at the provincial level. AS! BC helps elementary schools customize action plans, based upon their local context, to contribute to the health and well-being of children and the school community. Pilot research showed that AS! BC was an effective and feasible model. The provincial dissemination of AS! BC has been launched and partners from across many sectors are involved to enhance the sharing of knowledge and increase the implementation of the AS! BC model across British Columbia. The dissemination provides an unprecedented opportunity for evaluating how changing the school environment can promoted healthy weights in children. The dissemination was evaluated using a cluster randomized design; 30 elementary schools (n = 1529 consented children) from four (out of five) provincial health authorities volunteered to participate.

The primary goals of the research are:

Read more
  1. to determine if the Action Schools! BC (AS! BC) model is an effective approach to positively change school environments and health related behaviours of children from diverse geographical regions and cultural groups, and
  2. to determine if the supports provided to schools or the community context influence the uptake and use of the AS! BC model.

This research will contribute to the science of obesity prevention and knowledge use as well as public health practice.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Action Schools! BCBehavioural

    AS! BC applies a socioecological, whole school approach to promote healthy living within the elementary school context. Schools are provided with the tools and support needed to create customized action plans that promote physical activity (PA) and healthy living across six Action Zones (School Environment, Scheduled Physical Education (PE), Classroom Action, Family and Community, Extra-curricular, School Spirit). Generalist teachers receive training and resources to implement their Action Plan with the ultimate goal of providing students with 150 minutes of PA/week. The model is choice-based; teachers are asked to provide 15 additional minutes of PA/day within the Classroom Action Zone. The activities require minimal equipment and can be performed in the classroom, hallway or on the school playground.

    Student level

  6. Physical fitness (Fitnessgram (C))

    Student level

  7. Children's leisure time physical activity (PAQ-C)

    Student level

  8. Children's dietary intake

    Student level; 24 hour recall and food frequency survey

  9. Physical activity interventions planned

    School level; as measured by Action Plans

Secondary outcomes (1)

  1. Contextual factors surrounding the use of the intervention

    School level

    • School and community partnership survey
    • Annual focus groups with school planning teams, regional advisory committees, parent advisory committees, the local healthy living alliance
    • Semi-structured telephone interviews with school administrators, AS! BC regional facilitators, public health nursing staff, local nutritionist, municipal recreation staff and representatives of non-government organizations involved in chronic disease prevention locally
    • Review of AS! BC annual reports and action plans
    • Participant observation form to assess development of communities of practice
