Abstract

Objective:

Association between physical activity and atrial fibrillation (AF) was unclear. We aimed to examine whether frequency of physic activity influences the development of AF in population who had health examination.

Design and Method:

The study population was 211,992 (129,407 men and 82,585 women) for health examination who were free from atrial fibrillation at baseline. Incident AF cases were identified through yearly follow up electrocardiograph. Informed about physical activity was obtained from 211,992 AF free population who had completed a questionnaire. Participants reported number of exercise per week; 0, 1-2, 3-4, 5-7 exercise per week.

Results:

During a mean follow-up of 5.6years, AF occurred in 304 cases (278 men and 26 women). There was no significantly different in risk of AF (HR 0.81[0.50-1.31]) regardless of exercise. The multivariable relative risks of incident of AF was 1.00(0.74-1.37) for 1-2 exercise per week, 1.34(0.91-1.97) for 3-4 exercise per week, 1.27(0.72-2.23) for 5-7 exercise per week (P for trend <0.179) according to baseline exercise (per week).

Conclusions:

The frequency of exercise was not associated with incidence of AF.
