Measurement, causes and management of overweight and obesity in children.

Childhood obesity is a growing problem that has serious implications for future generations. The cause is multifactorial, with contributions from genetics and the environment. Management needs to be targeted at the population as a whole, with improved education and strategies to improve lifestyle and behaviour. Medication and surgery play a very small role in management, for use in exceptional circumstances. Only by empowering individuals and families to change will there be any impact on this epidemic.
