Abstract

Abstract: Objectives: The PREDIMAR (Prevention of arrythmias with Mediterranean diet -MedDiet-) trial is an ongoing randomized, parallel, multicenter study in Spain that began in 2017. The aim of this trial was to assess the effectiveness of a remote nutrition intervention in reducing the rate of atrial fibrillation (AF) relapses after ablation. Here, we compare 1-year changes in diet and other lifestyle factors between the intervention and control group. Methods: As of December 2018, 149 out of 484 recruited participants had completed the 1-yr follow-up visit. Among them, 77 received a remote intervention by a dietitian and 72 received the usual clinical care (controls). Adherence to the MedDiet was measured using a validated 14-point Mediterranean diet Adherence Score (MEDAS). Lifestyle was measured using a 7-point Healthy Lifestyle Score (HLS): physical activity, BMI, Mediterranean diet score, moderate alcohol consumption, TV watching, napping, and time spent with friends. Mean differences between baseline and 1-yr follow-up within and between groups were calculated with Student's t-test for statistical significance. Results: One-year changes in MEDAS were significantly better within the intervention group (2.48 pts. 95%CI:1.97–2.99) but not within the control group (0.29 pts. 95%CI: −0.21–0.79). We observed a significant increase in MEDAS in the intervention group compared to the control group (2.19 pts. 95%CI: −2.90–1.48). After 1-yr follow-up, participants in the intervention group significantly increased their consumption of fruits, vegetables, legumes, olive oil, fish, nuts, carbohydrates, fiber, and fat, by increasing MUFA and PUFA (all P < 0.05). We found a greater intake of fruits, vegetables, olive oil, fish, nuts, fat, MUFA, PUFA, and fiber, but less meat and alcohol, at 1-yr in the intervention group compared to the control group (all P < 0.05). After 1-yr follow-up HLS changes were not significant between groups. Conclusions: In the PREDIMAR trial, an online nutrition intervention complemented with telephone calls and printed materials effectively increased 1-yr adherence to the MedDiet without altering other lifestyle factors compared to the control group.
