Purpose
Atrial fibrillation (AF) is a frequently encountered cardiac arrhythmia in clinical practice. While fried food consumption is common in United States, little is known about the association between fried food consumption and incident AF.
Methods
We prospectively examined the association of fried food consumption with incident AF in 18,941 US male physicians. Fried food consumption was assessed via a self-administered food frequency questionnaire. Incident AF was ascertained through yearly follow-up questionnaires. Cox regression was used to estimate relative risks of AF.
Results
The average age at baseline was 66 ± 9 years. During a mean follow up of 9.0 ± 3.0 years, 2099 new cases of AF occurred. Using < 1/week of fried food consumption as the reference group, multivariable adjusted hazard ratios ( 95% confidence interval) for AF were 1.07 (0.97, 1.18) and 1.03 (0.91, 1.17), for people reporting an average fried food consumption of 1–3/week and ≥ 4/week, respectively, p linear trend 0.4. In a secondary analysis, the results did not change after exclusion of participants with prevalent coronary heart disease or congestive heart failure. Lastly, the source of fried food (away from home or at home) did not influence the relation of fried food with AF risk.
Conclusions
In conclusion, our study does not provide evidence for an association between fried food consumption and incident AF among US male physicians.
