Step Up For Health Study: A Pedometer and Website Intervention in Those With Prediabetes

Prediabetes Clinical Trial

Official title: Step Up for Health: A Pedometer-based Randomized Controlled Trial for Individuals at High Risk for Type 2 Diabetes

Status Terminated

Clinical Trial Summary

This study will examine whether a physical activity program, specifically increasing walking steps, offered over the internet is able to increase physical activity in adults with prediabetes. The study will take place over 12 weeks. The investigators want to see if people who receive the intervention increase their physical activity more than people who do not receive the intervention. The physical activity program will include using a pedometer to track daily step counts online, set weekly goals, and receive motivational messages delivered weekly using email. The investigators are also going to collect data on waist circumference, body weight and quality of life at baseline, 12 weeks and 16 weeks after the intervention has completed to see if these change over the course of the study. The investigators will be recruiting 200 adults who have attended the Edmonton, Alberta prediabetes education class offered by Alberta Health Services, Nutrition Services and report they have prediabetes. If able to successfully increase physical activity, this study will identify a web and home-based intervention that can be offered to individuals who participate in lifestyle programs delivered in primary care settings (e.g., Edmonton prediabetes program) in both rural and urban locations.

Clinical Trial Description

Relevance to diabetes: Without intervention, most people at high-risk of diabetes (e.g., with prediabetes) will eventually develop type 2 diabetes over time. Moderate physical activity of 150 minutes per week has been demonstrated to improve glucose tolerance and decrease type 2 diabetes risk. Research is needed to determine the effectiveness and acceptability of web-based methods of increasing physical activity, specifically walking, in these high risk populations.

Brief background of the issue: Studies completed in adults with prediabetes have demonstrated lower physical activity levels than the general population; however, adults with prediabetes have reported they are interested in a physical activity program that is focused on individuals with prediabetes.

Objective: To determine if a theoretically-based physical activity internet website with pedometer step and physical activity monitoring is able to increase physical activity behavior among adults at high risk of type 2 diabetes.

Hypothesis: Individuals at high risk of type 2 diabetes randomized to the intervention group will increase their pedometer steps and physical activity over a 12-week intervention compared to individuals in the control group.

Methods: Four hundred adults at high risk of type 2 diabetes will be recruited from the Edmonton and Calgary prediabetes education classes by Registered Dietitians (RD) teaching the class. The RD will discuss the study and interested participants will receive a pedometer, waist circumference tape and study information letter at the class. In the study information letter they will be directed to a website where they can agree to participate in the study after completing a brief questionnaire to determine study eligibility and a Physical activity readiness (e-ParMedX) form to determine physical activity safety. After completing these documents, if they are eligible to participate they will complete an online baseline questionnaire, a 3-day pedometer step test and a waist circumference measurement. All measurements and personal information will be recorded on the secure website. These measurements will be repeated at 12 weeks and 16 weeks post intervention. Upon completion of the baseline measures, they will be randomized by the website program into either the control or intervention group. The intervention group will receive a theoretically-based 12-week intervention program via the website designed to increase their physical activity and steps. The website content is based on the theory of planned behaviour and tailored to people at high-risk of type 2 diabetes. Participants will receive weekly information that is temporally sequenced on the website for each of the 12 weeks, set weekly goals and record their daily steps on the website. After the control group has completed their six-month assessment they will also be able to access the 12 week intervention.

Application to Practice: If able to successfully increase physical activity, this trial will identify a theoretically-based web and home-based intervention that can be offered to individuals who participate in lifestyle programs delivered in primary care settings (e.g., Edmonton prediabetes program) in both rural and urban locations. Research is needed to determine the effectiveness and acceptability of web-based methods of increasing physical activity, specifically walking, in these high-risk populations. ;
