Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention consisted of a 90 minute, peer-led, small group education session. The session content included teaching the recommended intakes and serving sizes for fruit and vegetables; the amount of the food budget that should be spent on fruit and vegetables and the health benefits of fruit and vegetables for the family. The budgeting aspects of the sessions helped to enhance the participants' motivation to purchase and consume more fruit and vegetables, whilst recipe modification and strategies for including fruit and vegetables throughout the day helped to define an ‘action’ phase of how to make the changes. The sessions were supported with printed educational materials including a cookbook. The sessions were followed by a newsletter mailed to participants at week 2 and 5 after attending the session. The newsletters were designed to reinforce what was learnt at the sessions, to provide further educational information and to motivate participants to make the required changes in consumption.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Recruitment of participants to the trial was from free-living community members using newspaper advertisements and other advertising, word of mouth, recruitment presentations or recruitment through schools, sporting clubs, shopping centres and other community organisations. There were no incentives offered for participation. Participants were not charged to attend the educational sessions and all resources were provided at no cost.
Participants were screened for inclusion using a pre-defined telephone script by Project Officers or Project Volunteers. Eligible participants were then posted written informed consent forms and were asked to complete the pre-program surveys. Once participants returned their forms by mail, they were allocated to either the intervention or the control group in order of receipt of the envelopes by mail. The trial continued until a sufficient sample size had been attained.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The group allocation sequence was generated via computer-generated randomisation.
Masking / blinding
