- Overweight and obesity prevention in childhood and adolescence represent a priority target for public health. Scientific literature recommends multidisciplinary (multicomponent) interventions in order to modify the time trend of childhood obesity and the school is considered one of the most favourable settings.
- Children in the age range 8 to 10 (end of primary school) already have preferences on food choices and physical activity, but they still are susceptible to change in response to positive reinforcement by parents, teachers, friends and schoolmates.
- The strategy of empowering parents during intervention by telephone calls, following an intense motivational programme, to stimulate adherence to physical activity targets and to remove barriers has been receiving increased attention.
