Text Messaging for Weight Loss in Primary Care Patients
Overweight and obese adults recruited from the primary care setting (n=150) will be enrolled
in a 6-month randomized trial of the INTERVENTION versus CONTROL. Both groups will receive
usual medical care, printed materials, and educational text messages. The INTERVENTION group
will also receive personalized coaching and feedback, as well as peer support, via text
message.
The investigators hypothesize that compared to those in the Control group, patients in the
Intervention group will lose more weight and demonstrate more favorable changes in fruit and
vegetable intake, exercise, and social support for weight loss.
