Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention participants will partake in a 12-week physical activity program during which they will wear a pedometer and use an online resource. The main focus of the online resource is a step log where participants enter their daily step counts, perception of exertion (RPE) and feeling (affect) daily. Based on this information they will be emailed weekly step count goals. The website will also include an interactive forum that links participants to other participants undertaking the study in the intervention group. There will be a virtual notice board where community service organisers can advertise events and activities relating to physical activity and general health and wellbeing. Information on healthy eating will be provided based on the recommendations in The Australian Guide to Healthy Eating (developed by the Australian Government, Department of Health and Aging). Participants are free to use (or not use) the program at their discretion. Adherence will be monitored by the number of logins to the website and progress phone calls which will occur weekly, but taper off as the intervention progresses and to foster independence.

Health measures such as height, weight, blood pressure, waist and hip girths and blood chemistry will be collected. Participants will also be asked to fill out questionnaires relating to their physical and psychological wellbeing and complete a food frequency questionnaire.

Behaviour
Comparator / control treatment
The control group will also be asked to wear a pedometer over the 12-week program. However, they will receive a paper logbook to record their daily step counts instead of access to the website. They will receive only one progress phone call (week 2) to ensure they understand their requirements for the study. They will receive weekly step goal emails, however these will be standardized across all control participants, with the aim of reaching the recommended 10,000 steps in week 12 of the program

Efficacy
Statistical methods / analysis
A total of 300 participants (150 per region) at baseline will provide sufficient statistical power to address the study aims, given the attrition rate of 30% observed in our recent pilot pedometer intervention. At a power at 80%, alpha at 0.01, a medium effect size of Cohen`s d = 0.5, and assuming that the predictors will contribute an R2 of 50%, a sample size of 212 is required. With a 70% retention rate a baseline sample of 300 will be adequate.
