At least one in four BC children and youth is overweight or obese, and many of these young people are already developing serious diseases, such as hypertension and type 2 diabetes. Preventative and therapeutic measures have not succeeded in curbing the prevalence of overweight and obese children and youth in BC and Canada. This award supports the development of a multidisciplinary team bringing together clinical, social and basic researchers. The team aims to study determinants of childhood and adolescent overweight at individual, family, community and population levels, and to develop targeted interventions that will result in sustainable outcomes and healthy body weights.
