Abstract
Background -This pilot study evaluated the feasibility (recruitment, retention, adherence and satisfaction) and preliminary efficacy of a 12-week website and email-linked counselling intervention on physical activity behaviour change in individuals with type 2 diabetes.Methods -A total of 49 individuals with type 2 diabetes (59% female, average age 54.1 years) were randomized to the Diabetes NetPLAY intervention or control condition. The intervention condition received information grounded in the Social Cognitive Theory (SCT), personalized weekly emails, an on-line logbook and message board. Key outcomes included physical activity behaviour and related cognition changes. The control condition was provided links to the Canadian Diabetes Association's Clinical Practice Guidelines for Physical Activity and Canada's Guide to Physical Activity.Results -Intervention participants indicated high levels of satisfaction for this mode of delivery and study results demonstrated the feasibility of web-based mediums for the delivery of physical activity information in this population. The intervention group demonstrated a significant improvement in total vigorous and moderate minutes of physical activity (p = 0.05) compared to the control group over the 12-week study. Among the SCT variables, behavioural capacity, showed a significant increase (p < 0.001) among intervention participants.Conclusion -Web-based interventions for individuals with type 2 diabetes are feasible and show promise for improving positive physical activity outcomes.
Highlights
Physical activity has long been recognized as one of the cornerstones of diabetes management [1]
There is an increasing need to deliver cost-effective physical activity interventions to large numbers of individuals living with this chronic disease
With internet and email becoming a primary mode of communication, an opportunity exists to utilize information technology to elicit physical activity behaviour change
Summary
Physical activity has long been recognized as one of the cornerstones of diabetes management [1]. Physical activity, including aerobic and resistance training, can assist individuals with type 2 diabetes in achieving a variety of goals including improved glycemic control, increased cardiorespiratory fitness, decreased insulin resistance, improved lipid profile and weight management [2]. Individuals with diabetes report high inactivity rates, with more than 60% of adults not meeting recommended physical activity guidelines [5,6]. Information is available to users 24 hours a day allowing for information to be viewed at their convenience It houses components such as chat rooms and web conferencing which can facilitate social support and communication from other users and health care providers [11]. Literacy levels and computer skills are potential barriers that individuals may face when using this type of technology to access health information
