Think tank on school-aged children: nutrition and physical activity to prevent the rise in obesity.

The rise in childhood obesity has generated concern across a range of sectors. Stakeholders and experts in the area of children's health met at a Think Tank in Toronto organized by the Canadian Council for Food and Nutrition and the Program in Food Safety, Nutrition, and Regulatory Affairs at the University of Toronto to discuss the current evidence in place to inform the development of school policies to reduce childhood obesity. Although there is some evidence to suggest that school interventions may reduce obesity in children, there are other examples of programs that have had very little impact. The role of parents in the development of healthy eating and physical activity patterns is critical from the earliest stages of life and warrants further attention. Delegates agreed that we need ongoing input of experts and leaders from all sectors and fields to help us to effectively promote healthy lifestyles at schools and within the home, while respecting each child's need for safety, security, and respect.
