About
The objective of this study was to assess the effectiveness of a 6-month text-based mobile health and wellness (mHWC) intervention, as compared to usual care (UC), for weight loss in adults. Participants were randomly assigned to one of the two groups (mHWC or UC). At the beginning of the study, both groups were given a Fitbit wearable device, and a weight scale. All participants also received a counseling session from a dietician focused on diet, physical activity, and sleep, and were set up on the Nudge app, a commercially-available mHWC platform. Participants in the mHWC group received text-based coaching messages via Nudge and did not return to the clinic for the duration of the 6-month intervention. Those in the UC group met once a month with a pharmacist or dietician for 6 months. In both groups, the focus was on facilitating health behavior change related to diet, physical activity, and sleep to promote weight loss.
We hypothesized that weight loss at 6 months would be greater in the mHWC group vs. the UC group.
