65 participants completed baseline (mean age 44.9; mean BMI 33.2).
A total of 65 participants (mean age 44.9 years, mean weight 89 kg, mean BMI 33.2 kg/m 2 ) completed baseline measures and were included in the analyses; 80% were women, 75% were white, and 17% were African American ().
Intervention lost 1.97 kg more than comparison at 4 months (P = .02).
At the end of 4 months, the intervention group lost more weight than the comparison (1.97 kg more; P = .02), after adjusting for time, sex, and mean age.
Key findings
Intervention participants lost more weight than comparison participants (about 1.97 kg more; adjusted losses ~2.88 kg vs 0.91 kg).
Methodology
Researchers randomized overweight adults who used mobile phones to a 4-month program of daily tailored SMS/MMS prompts plus brief monthly counselor calls, versus monthly print materials, and tracked weight at 0, 2, and 4 months.
Limitations
Short follow-up cannot show long-term maintenance, and the sample was modest and mostly female.
