Adherence
A 1-year mHealth intervention using motivational interviewing calls and SMS text messages produces sustained, statistically significant reductions in body weight and BMI four years after the intervention concludes, with greater effects observed in participants receiving at least 50% of the scheduled calls.
If you have prehypertension and live in a resource-limited setting, a structured mobile health program involving monthly coaching calls and weekly text reminders can help you lose weight and keep it off for years. You don't need to be perfect; receiving half or more of the scheduled calls was enough to see significant, lasting benefits in body weight and BMI. Focus on the core behaviors: reducing sodium, fat, and sugar, while increasing fruits, vegetables, and physical activity.
An mHealth intervention comprising motivational interview calls and SMS text messaging appears to have effects on health 4 years after intervention completion. Although there were no effects on blood pressure levels, important reductions in body weight and BMI were seen 5 years after randomization.
