Overweight adults achieved significant weight loss using a mobile phone intervention. Daily text and multimedia messages, along with counseling, proved effective for weight management.

Area of Science:

  • Health behavior change
  • Digital health interventions
  • Obesity research

Background:

  • Limited research exists on using mobile phone text and multimedia messages for weight loss in overweight adults.
  • Previous interventions have not extensively utilized daily SMS and MMS for weight management.

Purpose of the Study:

  • To develop and evaluate a mobile phone-based intervention for weight loss or maintenance.
  • To assess the efficacy of personalized text and multimedia messages in a 4-month study.

Main Methods:

  • A randomized controlled trial compared a mobile intervention group with a control group receiving printed materials.
  • The mobile intervention included daily SMS/MMS messages, printed materials, and monthly phone calls over 16 weeks.
  • Weight change was analyzed using mixed-model repeated-measures and ANCOVA, adjusting for baseline weight, sex, and age.

Multidisciplinary Approach to Obesity Management: A Case Report

Published on: May 30, 2025

Main Results:

  • The intervention group (n=33) experienced greater weight loss than the comparison group (mean difference -1.97 kg, P=.02).
  • Intervention participants achieved an average adjusted weight loss of 2.88 kg (3.16%).
  • 92% of intervention participants would recommend the program for weight control.

Conclusions:

  • Mobile phone text messaging is a promising communication channel for promoting weight loss behaviors.
  • Digital interventions can effectively support weight management in overweight populations.
  • Personalized SMS and MMS interventions demonstrate potential for public health applications in obesity prevention.
