Scientific title
Acronym
LEAP 2
Study hypothesis
Added as of 16/08/2007:
1. A brief parent-focused behavioural intervention delivered by General Practitioners (GPs) to overweight/obese 5 - 9 year olds will halve the body mass index (BMI) gain (the primary outcome) at 6 and 12 months in the intervention group relative to the non-intervention group
2. A brief parent-focused behavioural intervention delivered by GPs will lead to a range of secondary outcomes at 6 and 12 months for children and their families in the intervention compared to the non-intervention group, including:
2.1. Smaller measured child waist circumference
2.2. Greater measured child physical activity
2.3. Parent-reported increases in child physical activity, reductions in sedentary activity, changes in child eating patterns
3. The intervention will be acceptable, feasible and cost-effective within Australian GP settings
