REVUP : Cardiovascular risk outcomes from a healthy lifestyle intervention

Introduction: Workplaces provide researchers and employers with an opportunity to engage in the health behaviours of employees. Despite the number of Australians in employment, many employers do not have meaningful programs to aid in the development of healthy behaviours. Internet delivered programs have advantages of reduced cost, ease of implementation over distance, and reliance on previously existing infrastructure. The Aim of REVUP is to assess the effectiveness of an online delivered, workplace health program on improving health risk factors.

Method: The REVUP study was a single-blind, randomized controlled trial. Targeted participants were aged between 18 and 80 years and engaged in employment with the Uniting Church of Australia. A 12-week program was delivered via two emails per week, containing a video link and newsletter with activities. A range of topics was presented including physical activity, diet, goal setting, smoking cessation, and mental wellness. A comprehensive testing battery was utilised including objective measures of physical activity, blood testing, physical capacity assessments, and questionnaires.

Results: Adoption and adherence to the program was low. Amongst the 36 individuals interested in the program 21 participants were randomised, with 15 completing the program. No significant differences were detected in any outcome measures. Adjusted effect sizes show promising results.

Discussion: Significant barriers exist to the adoption and efficacy of internet delivered workplace health programs. Future programs may benefit from implementation of technology and structures that aids the development of intrinsic motivation and social support. Substantial integration of psychological theory, particularly in developing autonomous supportive environments is likely needed to support adherence and effective outcomes.
