Description of intervention(s) / exposure
Project Energize is a school-based nutrition and activity programme which aims to increase children’s activity levels, reduce sedentary time, and optimise nutritional
intake through changes in the school environment and culture. Potential benefits of this include increased ability to participate, improved body composition, improved dental health, and improvements in a range of associated health measures.
In 2004 primary schools (124) in the Waikato district were randomised to an intervention (62) or control (62). Energize staff (‘Energizers’) work with between 6 and 8 schools and each school developed with the Energizer an individualised action plan based on the individual needs of the school.
Supported by the Energizer within the school, physical activity interventions were aimed at encouraging and aiming for 20 minutes of high intensity physical activity every day; Increasing children’s lunchtime physical activity; Increasing children’s exercise everyday at home; and Increasing children’s incidental activity. The optimisation of children's nutritional intake was by Encouraging the ready provision of water for all children and promoting water intake; Decreasing children’s carbonated beverage intake (at school and at home); Decreasing the availability of energy dense foods at school and home;and Increasing fruit and vegetable intake at school and home.
Examples of facilitation include physical activity sessions modelled with teacher, leadership training for senior students, home school link programmes established, physical education and nutrition curriculum assistance, schools supported to achieve the National Heart Foundation's school food programme, works shops for sportiing disciplines provided.
The control schools were on a wait-list and are now all receiving the intervention as are all primary schools in the Waikato district.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Schools (not children) were randomised in a stratified manner by location, size of school, ethnicity of children and school decile. Randomisation of the school occured after recruitment of schools and schools notified of their status. Allocation was not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
random number was generated electronically for each school within the Statistical Package for the Social Sciences statistical software package (SPSS Inc., Chicago,IL, USA). Intervention schools within any stratum were selected from highest to lowest random number, and control schools from lowest to highest.
