A multidisciplinary primary prevention intervention to increase adherence to the Mediterranean diet: a pilot study

The role of the Mediterranean Diet (MD) in reducing cardiovascular (CV) risk is widely demonstrated and many studies have shown the effectiveness of educational interventions in primary prevention. This study aimed to evaluate the impact of a multidisciplinary educational intervention, that included nutritional, psychological and physical activity coaching, on adherence to MD and on CV risk.

In a Roman neighborhood, general practitioners enrolled 41 subjects to take part in the educational intervention from November 2018 (T₀) to November 2019 (T₁). Participants' anthropometric measures, haematochemical parameters and CV risk score were assessed before and after the intervention. Furthermore, their adherence to MD was evaluated through the analysis of food frequency questionnaires using Medi-Lite.

The study found a significant reduction of 2.5 points in individual CV risk score, and an increase of 2.5 point in adherence to the MD. The stratification by gender showed statistically significant decreases in weight of 1.16 kg, BMI of 0.47, LDL cholesterol of 14.00 mg/dL, and individual CV risk score of 1.16 points among female participants.

These results show that a multidisciplinary educational intervention model including the adoption of MD could be an effective strategy in Public Health for CV primary prevention and improvement of people's lifestyles.
