This review of 9 high-quality studies assessed the effectiveness of app-based lifestyle interventions.
Lifestyle outcomes were physical activity, physical fitness, body weight/waist circumference, modification of dietary habits, glycated hemoglobin (HbA1c) and quality of life. Patients in all studies monitored themselves for at least 3 months on lifestyle factors (exercise, diet) and clinical measurements (blood glucose, weight, blood pressure etc). In some studies, patients were monitored by researchers as well.
As exercise is an important aspect in self-management; it is interesting that none of the studies included in this review objectively measured physical activity or physical fitness.
A statistical significant effect was shown in HbA1c in 5 of 8 studies, as well in body weight in 1 of 5 studies and in waist circumference in 1 of 3 studies evaluating these outcomes.
