Effectiveness of a Nurse-led Personalized Telephone Intervention on Lifestyle Changes in Diabetes Prevention.

Effects of a 9-months Nurse-led Telephone Personalized Lifestyle Intervention Versus Automated SMSs on Nutritional and Physical Activity Advice on Glucose Profile in Patients With Prediabetes

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.

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).

Patients assigned to this group will receive personalized dietary and physical activity advice during 9 months. Behavioural goals and action plans will be developed in a stepwise manner in accordance with baseline levels of nutritional and physical activity adherence to recommendations.

Patients assigned to this group will receive a total of 150 text messages (4 to 5 messages per week during weekdays) throughout the intervention period (9 months). The content of the text messages includes advice on diet and exercise.

Whether lifestyle changes acquired during the 9-month active-intervention phase are maintained in the mid-term.
