The intervention will run over 2 years (2010-2011) with children in grades 3 and 4, with a 12 month follow up in 2012. The study will assess the effectiveness of strategies to promote physical activity and reduce sedentary time in both the school and home setting, to determine what works and the impact on children's health. This effectiveness data will be combined with the economic cost of each intervention arm to determine the trial cost-effectiveness.
The aim is to determine whether a 2 year multi-setting behavioural intervention targeting sedentary behaviours and physical activity alone and in combination results in lower rates of sedentary behaviours and higher levels of physical activity among 8-9 year old children compared with current practice.
Twenty Victorian primary schools have been randomly assigned to 1 of 4 groups
Children aged 8-9 years at recruitment from a range of socioeconomic areas across metropolitan Melbourne are involved and will be studied until 11-12 years of age.
