Description of intervention(s) / exposure
The efficacy of the web 2.0 physical activity intervention will be tested initially in a randomised controlled trial (ACTRN12611000157976). The ecological trial will complement the randomised controlled trial by providing additional information about the recruitment and retention capabilities of the intervention using a self-selected sample of real-world users of an existing health promotion website. Since 2007, the 10,000 Step website has averaged approximately 1,000 new registrants per month. During the recruitment phase of the ecological trial, all individuals who register, of their own impetus, with the online program will be presented with an option to participate in the study and provide informed consent.

The primary intervention group will receive access to an interactive website with web 2.0 content including streams, social media connectivity and other innovative content. 1447 participants will be recruited to this group.

Participants' interactions with the website will be monitored for the duration of the project (1 year). Time spent interacting with the website is self-selected and internet engagement (number of hits, session duration) will be monitored and, combined with self-reported physical activity patterns, used to examine utility of the site in promoting physical activity.

Comparator / control treatment
The comparison group will receive access to an existing website with web 1.0 content. This website will consist of basic features allowing participants to record their physical activity, access health information and communicate with other users of the web 1.0 platform via a forum. 1447 participants will be recruited to this group.

Participants' interactions with the website will be monitored for the duration of the project (1 year). Time spent interacting with the website is self-selected and internet engagement (number of hits, session duration) will be monitored and, combined with self-reported physical activity patterns, used to examine utility of the site in promoting physical activity.
Control group
Active

Outcomes
Primary outcome [1] 262221 0

Secondary outcome [1] 273349 0
The secondary outcome measure will be self reported Body Mass Index (BMI). Information regarding height and weight will be collected from all trial participants by means of online survey.
Timepoint [1] 273349 0
At baseline and at 3 months and 1 year
Secondary outcome [2] 273454 0
Internet engagement will be measured through the number of hits that a user registers and the mean session duration.
Timepoint [2] 273454 0
At baseline and at 3 months (as a minimum) and 1 year.

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)
Participants involved in the Walk 2.0 RCT (ACTRN12611000157976) will not be allocated to either condition in this study. The ecological trial will be conducted using a self-selected sample of real-world users of an existing health promotion website. Since 2007, the 10,000 Step website has averaged approximately 1,000 new registrants per month. During the recruitment phase of the ecological trial all individuals who register, on their own impetus, with the online program will be presented with an option to participate in the study and provide informed consent. On electing to participate, users will be randomly allocated to the intervention (Web 2.0) or comparator (Web 1.0) groups by computer generated algorithm.

Summary
Brief summary
More than half of the Australian population do not meet the levels of physical activity recommended to achieve health benefits. The Internet has become an increasingly important communication tool, and Internet based physical activity interventions which include innovative technology have the potential to reach large groups of individuals and contribute to the promotion of physical activity and behaviour change. Each year there is a proliferation of health-related and health-promotion websites, yet virtually no work has been done to study the utility and effectiveness of these population-targeted websites. This study will develop a website featuring Web 2.0 applications and evaluate the efficacy and utility of the website to promote physical activity in comparison to a conventional (Web 1.0) physical activity promotion website. The ET takes advantage of the unique 'real world' sample available to the research team through the existing 10,000 Steps website to evaluate engagement by users from the broader community.
The efficacy of the intervention is initially being tested in the in a randomised control trial (RCT). The RCT is investigating efficacy, adherence and behaviour change in a rigorous, controlled setting with high internal validity. The RCT has been registered separately (ACTRN12611000157976).
We expect that the current proposal will provide an increased understanding of the benefits of newer web-based technologies and applications in engaging and retaining participants on web-based physical activity promotion sites. This work has the potential to improve health outcomes from increased engagement/retention in physical activity.
