Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will employ a two level cluster randomised controlled design where the primary cluster is the school and the secondary cluster is the class. Eligible schools who agree to participate in the study will be stratified by school size and geographic location then randomly allocated to either intervention or control group. The term in which the school participates in the trial will also be randomly allocated at this time.

Intervention Schools
During weeks 2 to 7 of the school term, students in intervention schools will receive the Shake-A-Leg program; one session per week, during class time for approximately 40 minutes. Students will also receive additional Physical Activity and Nutrition content at each of these sessions for approximately 5 minutes. Session will be delivered by qualified Aboriginal Health workers

Session 6: Bullying

Data collection
Data will be collected using paper-based questionnaires by trained research assistants from Hunter New England Local Health District (HNELHD) Aboriginal Health Unit and Population Health Unit. Data collection will be conducted in all participating schools (intervention and control) at two points. Baseline data during week 1 of their allocated school term and post-intervention data will be collected in week 8 of the same term. All data will be re-identifiable, with each child being allocated a unique study number so that baseline and post-intervention data can be matched.

Attendance of participating students will be recorded at each session. Data from students who did not attend at least four sessions, two of which must be physical activity and nutrition, will be excluded from analysis.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Proportional stratified random sampling will be used to randomise participating schools. Randomisation by using a randomisation table created by computer software facilitated by an independent statistician. Schools will be randomised in to intervention or control groups with a 50/50 ratio.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Schools will be allocated to study groups using a block randomisation for each combination of stratification level. Randomisation will be created using the PLAN procedure in SAS 9.3

Efficacy
Statistical methods / analysis
The target sample size (addressed in section 7) refers to the required sample size for Aboriginal Students.

To detect a statistically significant change in Aboriginal students with probability (power) 0.8, an alpha level of 0.05, an intra-cluster correlation of 0.5 and control group prevalence of 50%, the trial will require 466 eligible Aboriginal participants (233 per study group) at follow-up.

When accounting for an estimated average of 20% Aboriginal student population among eligible schools, an 80% parental consent rate, and a 10% loss to follow up, it is estimated that 3200 total students will be invited to participate in the trial, including 644 Aboriginal students.
