Frequently Asked Questions (FAQ)
What is the purpose of this study?
Overweight and obesity are associated with a number of chronic diseases, including type 2 diabetes (T2DM). Many studies in the past have shown that group-based interventions are effective for both overweight/obesity and T2DM prevention and management; social support plays a key role in facilitating weight loss. For this study, we are using electronic and mobile health technologies; we will examine the use of a mobile app that we have developed on helping people to track their diet, physical activity, and provide social support to one another.
What’s the study about?
The mLife study aims to help people to lose weight while using different digital technologies for self-monitoring diet, physical activity and body weight. The intervention will last 12 months, and you will be asked to daily track all your meals via the mLife app, use a FitBit to track your physical activity, and use a FitBit scale to track your weight. Also, you will be expected to listen to 2 podcasts weekly and read an in-app tip of the day, these will provide you with information about healthy eating and strategies to stay active. The mLife app will also encourage and facilitate social support among fellow participants. You will be assigned to two versions of the app. Both are the same, but how the data are presented to you will be different. Additionally, at the beginning of the study, and again at 6 and 12 months of the intervention, we will ask you to complete some online surveys.
What will I get by participating?
You will receive a support system and accountability to help you lose weight. If you don’t already have a FitBit or a FitBit scale, those will be provided to you. You can receive up to $100 for completing the 12-month study.
