BACKGROUND: Although research has demonstrated that diabetes prevention programs (DPPs) can decrease the incidence of diabetes, traditional DPPs have limited access. As a result, these programs are severely underutilized despite federal policies that support national diabetes prevention efforts. Digital diabetes prevention programs (d-DPPs) offer great promise for increasing accessibility of diabetes prevention efforts. However, little is known regarding the degree to which engaging in d-DPPs impacts treatment effects. The purpose of this study is to evaluate the impact of participant engagement on changes in HbA1c and body weight resulting from a commercially available (d-DPP). METHODS: This study will involve a secondary analysis of data from the Preventing Diabetes with Digital Health and Coaching for Translation and Scalability (PREDICTS) Trial. PREDICTS was a randomized clinical trial that tested the effects of a 12-month d-DPP on HbA1c and body weight. The d-DPP was compared to a small group education program in 599 adults with prediabetes. Participant engagement in the year-long d-DPP will be measured by the following criteria: a week where a) weight was logged, b) the lesson was completed, and c) there was at least one coach/group interaction or meal logged. Total weeks of engagement will be summed across the 52-week program. We will use scatterplots and Pearson correlations to examine the relationships between engagement, HbA1c and weight loss. Additionally, we will create categories of high, moderate, and low engagement and examine between group differences in HbA1c and weight loss. We will also use logistic regression to analyze the role of engagement in achieving 5% weight loss. RESULTS: We expect positive relationships between engagement and reductions in HbA1c and body weight. That as, the more engaged a participant is in the intervention, the greater the changes an individual will experience in HbA1c and body weight. Similarly, we expect that the higher engagement group will have significantly larger changes in HbA1c and body weight as compared to the other categories of engagement. We also expect that engagement will be a significant predictor in achieving 5% weight loss. The results of this study will provide valuable insight into the impact of a commercially available d-DPP, which has the potential to vastly increase access and reach of diabetes prevention programming.
