Background: Previous data validated the benefit of digital health interventions (DHI) on weight loss in patients in cardiac rehabilitation (CR). The purpose of this study was to test the hypothesis that increased DHI usage associates with improved weight loss.
Methods: We obtained DHI usage data including active days, total log-ins, tasks completed, educational modules reviewed, medication adherence, and non-monetary online incentive points in patients undergoing standard CR following percutaneous coronary intervention. A blinded statistician abstracted weight loss and dietary adherence to AHA/ACC secondary prevention guidelines at three months following study enrollment. Linear regression was used to evaluate associations between DHI activity and weight loss or dietary adherence.
Results: The participants (n=37) were 84% male with mean age 59.2±6.7 and mean weight loss 5.0±6.5 kg. Median log-ins was 10 (IQR 4, 37). We found a significant association of total log-ins during CR with weight loss (r2=0.07, p=0.04) and dietary adherence (r2=0.42, p=0.002). Participants who logged their weight had greater weight loss (r2=0.10, p=0.013), and those who logged dietary habits at a higher rate had improved dietary adherence (r2=0.42, p=0.028). Both educational modules viewed and tasks completed were associated with weight loss (Figure).
Conclusions: These data extend previous findings and demonstrate increased DHI usage portends improved weight loss and dietary adherence in patients undergoing CR.
