CAMBIO (Canada - Mexico Battling Childhood Obesity) is a multidisciplinary, international network of investigators participating in a project to enhance research capacity in the field of Childhood Obesity in Mexico. The network, led by Dr. Ian Janssen (Queen's University, Canada), and Dr. Juan López Taylor (Universidad de Guadalajara, Mexico), is strengthened by researchers specialising in Obesity, Epidemiology, Physical Activity and Health, Nutrition, Pediatrics, Population and Community Health, Sociology, Health Surveillance, Physiology, and other research areas.

The network promotes cooperation and knowledge transfer among educational institutions, government ministries, and non-governmental organizations, as well as other government, community-based, or industry-led groups whose focus is health, nutrition, physical activity, and the promotion of healthy communities.

Funding for the project is provided through a Teasdale-Corti Team Grant, from the International Development Research Centre, Canada, on behalf of the Global Health Research Initiative.
