The health of Canadian children and youth has deteriorated in the past few decades and physical inactivity is a powerful contributor. Active Healthy Kids Canada (AHKC; www.activehealthykids.ca) is a national not-for-profit organization with a mission to inspire the nation to engage all children and youth in physical activity by providing expertise and direction to policy makers and the public on how to increase and effectively allocate resources and attention toward physical activity for Canadian children and youth. Annually, for the past 7 years, the AHKC Report Card has consolidated and translated research knowledge to drive social action for policy change relating to physical activity among children and youth. Original published articles and key surveillance data from national and regional surveys are reviewed. A group of content experts from across Canada meet semiannually to review the evidence and assign letter grades. The AHKC Report Card has played a key role in informing discussions that have led to action on physical inactivity in Canada. Further evidence of the Report Card's influence is in the replication of the model in several other jurisdictions, including Saskatchewan and Ontario, Canada; Louisiana, United States; South Africa; Mexico; and Kenya.
