March 17, 2026 updated by: Centre Hospitalier Universitaire de la Réunion

Impact of SMS Reminder on Weight Loss, as Part of a Hygieno-dietary Health Pathway in Patients With Prediabetes: a Randomized Controlled Trial.

The goal of this interventionnal study is to demonstrate that sending SMS messages with advice on physical activity or nutrition, in addition to a program of hygienic-dietary management, significantly increases weight loss in subjects with prediabetes in La Réunion.

Indeed, type 2 diabetes is a priority health problem on Reunion Island: 10% of the population are treated for type 2 diabetes, twice as many as in France.

International studies have demonstrated the value of modifying dietary and physical activity habits to reduce the risk of transition to diabetes in patients with prediabetes Against this backdrop, a Regional Nutrition Diabetes Program (PRND) 2020-2023 was launched by Réunion's Regional Health Agency (ARS) in 2020.

Studies have also demonstrated the effectiveness of using SMS to encourage and support weight loss interventions.

So, the main question it aims to answer are:

• Does the addition of 72 SMS of physical activity and nutriton advice, to the "FindRisc Péi-CPTS" program, significantly increase weight loss by 3% after 6 months of starting the program.

FindRiscPei-CPTS program includes sports sessions, dietary consultations and therapeutic education.

The 300 participants will be randomized into two arms

  • 150 participants will take part in the FindRiscPei-CPTS program + receive SMS messages
  • 150 participants will only take part in the FindRiscPei-CPTS program (no SMS)

All participants will follow procedures below:

  • Inclusion: assessment of weight and waist circumference, Lifestyle Questionnaire and Socio-Efficacy Questionnaire.
  • Participation in Findrisk program for 3 to 9 months (+ SMS for experimental group)
  • 3 follow-up visits: 3 months, 6 months and 9 months after starting the program: weight and waist measurement, self-efficacy questionnaire.
