The REGARDS study enrolled 30,239 participants between 2003 and 2007; the analysis included 8,977 who were free of atrial fibrillation at baseline and completed a follow-up exam. Dietary patterns were assessed using a food frequency questionnaire. After a median follow-up of 9.3 years, 782 participants developed incident atrial fibrillation. In multivariable models, adherence to the Mediterranean Diet Score (OR per SD increment = 1.03; 95% CI 0.95–1.11) or a plant-based pattern (OR per SD increment = 1.03; 95% CI 0.94–1.12) was not associated with atrial fibrillation risk.

ABSTRACT

Abstract Background We examined whether the risk of incident atrial fibrillation (AF) in a large, biracial, prospective cohort is lower in participants who adhere to heart-healthy dietary patterns and higher in participants who adhere to less heart-healthy diets. Methods Between 2003 and 2007, the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort study enrolled 30,239 Black and White Americans aged 45 years or older. Dietary patterns (convenience, plant-based, sweets, Southern, and alcohol and salads) and the Mediterranean diet score (MDS) were derived based on food frequency questionnaire data. The primary outcome was incident AF at the follow-up visit 2013–2016, defined by either electrocardiogram or self-reported medical history of a physician diagnosis. Results This study included 8977 participants (mean age 63 ± 8.3 years; 56% women; 30% Black) free of AF at baseline who completed the follow-up exam an average of 9.4 years later. A total of 782 incident AF cases were detected. In multivariable logistic regression analyses, neither the MDS score (odds ratio (OR) per SD increment = 1.03; 95% confidence interval (CI) 0.95–1.11) or the plant-based dietary pattern (OR per SD increment = 1.03; 95% CI 0.94–1.12) were associated with AF risk. Additionally, an increased AF risk was not associated with any of the less-healthy dietary patterns. Conclusions While specific dietary patterns have been associated with AF risk factors, our findings fail to show an association between diet patterns and AF development.
