Description of intervention(s) / exposure
(1) The WASPA Physical Activity Program - Community based after school physical activity and healthy eating program conducted at a local community setting (leisure centre). The physical activity and healthy eating program focuses on increasing adolescents’ fitness, sporting skills, and physical activity, and improving their food habits and eating behaviours. The program will run for 20 weeks, with two 1.5 hour sessions each week. Adolescents will also be asked to complete two ‘additional’ physical activity sessions in their own time each week. The activities are designed to be enjoyable and to develop self-efficacy among participants whilst also accommodating their unique needs.

Parents will be asked to attend five dietary education sessions with an accredited practising dietitian. The adolescents will also participate separately in five sessions as part of the programme. These are aimed at guiding healthy eating choices through improving knowledge about portion sizes and label reading skills and preparing healthy alternatives such as afternoon snacks and meals.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Recruitment will commence approximately 6 weeks before the program commences. Numerous recruitment strategies will be employed to enhance recruitment success and include: personalised letters sent to school Principals inviting them to promote the study within their school and in school newsletters articles and posters places in general Practitioner (gp) surgeries, shopping centers and public libraries. The University of Wollongong media unit will distribute media releases resulting in newspaper articles and radio and television interviews and finally paid advertisements will be placed in local newspapers.

Interested participants will be sent an information package containing an information sheet and a consent form. Once written consent is received from both participants and their parents, participants will be randomized into either the intervention group or the control group.

Allocation was concealed: central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The bias coin method of allocation, using a computer-based random number-producing algorithm will be used for randomisation. This method ensures an equal chance of allocation to each group. Stratification by gender will be done to ensure an equal representation in groups. Only one study member will have access to the allocation codes and these will be stored on a pass-word protected computer.
