It is estimated that about 70% of the prediabetic population will eventually develop type 2 diabetes (T2DM), contributing to the significant economic burden on health systems and societies. When prediabetes is recognized, lifestyle intervention including weight loss through diet and exercise can reduce the relative risk of developing T2DM by more than 50% within 3 years. In the context of the current pandemic caused by COVID-19 the implementation of prevention strategies is heavily affected. Telemedicine consultations give patients the opportunity to receive personalized advice on disease prevention even in times of pandemic. Previous studies on telemedicine intervention strategies for the prevention of T2DM show that there is a need to further explore the utility of telemedicine and especially telephone-based personalized behavioural interventions in patients with prediabetes.The aim of the present research is to determine whether a nurse-led personalized telephone lifestyle intervention is effective in reducing risk factors associated with the development of T2DM in subjects with prediabetes, versus automated short message service (SMS).
A randomized, 9-months, parallel-group study comparing the effectiveness of a nurse-led telephone personalized lifestyle intervention versus automated SMSs on nutritional and physical activity advice in the reduction of fasting blood glucose and/or HbA1c in a population with prediabetes.
