A Mobile Health and Wellness Coaching Intervention for Weight Loss

Participants in the mobile health and wellness coaching (mHWC) group received text-based mHWC messages and did not return to the clinic until the end of the 6 month intervention. Messages were sent at least weekly and focused on facilitating the adoption and maintenance of health behaviors related to diet, physical activity and sleep to promote weight loss. Participants could respond via text at any time. The Nudge platform was used for all messaging.

Participants in the usual care (UC) group met in-person once a month with either a pharmacist or dietician for the duration of the 6-month intervention. The focus of these sessions was on facilitating the adoption and maintenance of health behaviors related to diet, physical activity and sleep to promote weight loss. These participants were set up on the Nudge app, but they did not use the mHWC (texting) feature.
