Study type
Interventional
Description of intervention(s) / exposure
Childcare centre cooks in the intervention arm will be mailed a hard copy printed education material together with sections of the nutrition guidelines relevant to menu planning. The design of the printed education material will be theory informed and based on evidence from key systematic reviews in the field. The printed education material will be printed a single A4-sized, double sided and laminated resource. The material will only be mailed out on a single occasion. No other strategy to encourage use of the resource will be undertaken. The number of intervention resourced returned and not successfully mailed out will be recorded internally.

Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A list of childcare service centres located in the New South Wales region (excluding the Hunter New England region) was obtained using a central government repository. A random sample of services was selected from the list. A research assistant examined whether each of the service provided meals to children by searching center websites. Eligible services were randomised to receive either the printed education material or usual care.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Childcare centres were randomly allocated to intervention and control group using the RAND function in excel by a statistician independent to the study.
Masking / blinding

Efficacy
Statistical methods / analysis
We required 154 participants to have 80% power of detecting an effect size of 0.45 standard deviations, with a significance level of 5%. Assuming a 70% response rate at follow up, we will approach 220 centres. An ANCOVA will be undertaken to assess the impact of the intervention on the primary oucome - intentions to use.
