Major initiatives related to childhood obesity and physical inactivity in Canada: the year in review.

This commentary briefly reviews 10 significant initiatives related to childhood obesity and physical inactivity in Canada in 2007. These include: the Children's Fitness Tax Credit; CAN-PLAY research findings from the Canadian Fitness and Lifestyle Research Institute; resurrection of ParticipACTION; Healthy Weights for Healthy Kids report from the Standing Committee on Health; launch of the Canadian Health Measures Survey; publication of the Canadian Clinical Practice Guidelines on the Management and Prevention of Obesity in Adults and Children; Canada's food and beverage industry initiatives launch; hosting the International Conference on Physical Activity and Obesity in Children; release of the Active Healthy Kids Canada report card on physical activity for children and youth; and publication of the "advancing the future of Canada's physical activity measurement and guidelines" project. The diversity and intensity of activity addressing the childhood obesity and physical inactivity "epidemic" in Canada is encouraging and must be maintained.
