Adherence
Combined digital interventions (dietary, physical activity, and smoking cessation) significantly decrease BMI compared to nondigital combined interventions.
If you are making multiple lifestyle changes (diet, exercise, quitting smoking), using a digital tool may yield better results for BMI reduction than traditional methods alone.
ModerateQualifiesMEDIUM confidence
Combined digital interventions (dietary, physical activity, and smoking cessation) significantly decreased BMI (MD = −0.20, 95% CI [−0.36, −0.04]) compared to nondigital interventions.
