Mobile health messages help sustain recent weight loss.

Journal Article

BACKGROUND: Using regulatory focus theory, an intervention of daily weight loss-sustaining messages was developed and tested for acceptability, feasibility, and efficacy on helping people sustain weight loss. METHODS: Participants (n = 120) were randomized to a promotion, prevention, or an attention-control text message group after completion of a weight loss program. Participants completed baseline assessments, and reported their weight at 1 and 3 months postbaseline. RESULTS: Participants found the message content and intervention acceptable and valuable. A minimum of one message per day delivered at approximately 8:00 am was deemed the optimal delivery time and frequency. The sustained weight loss rate at month 3 for the control, promotion, and prevention groups was 90%, 95%, and 100%, respectively. Medium-to-large effects were observed for the promotion and prevention groups at month 1 and for prevention at month 3 relative to controls. The mean weight loss for promotion and prevention was 15 pounds, compared with 10 in the controls at month 3. CONCLUSION: A clinically significant decrease in mean weight, higher rate of sustained weight loss, and medium-to-large effects on sustained weight loss occurred in the promotion and prevention interventions. Tools such as this text message-based intervention that are constructed and guided by evidence-based content and theoretical constructs show promise in helping people sustain healthy behaviors that can lead to improved health outcomes.
