摘　　要：BACKGROUND Atrial fibrillation(AF)is a common cardiac arrhythmia in the elderly.This study aimed to evaluate urban-rural disparities in its prevalence and management in elderly Chinese.METHODS Consecutive participants aged≥65 years attending outpatient clinics were enrolled for AF screening using handheld single-lead electrocardiogram(ECG)from April 2017 to December 2022.Each ECG rhythm strip was reviewed from the research team.AF or uninterpretable single-lead ECGs were referred for 12-lead ECG.Primary study outcome comparison was between rural and urban areas for the prevalence of AF.The Student’s t-test was used to compare mean values of clinical characteristics between rural and urban participants,while the Pearson’s chi-square test was used to compare between-group proportions.Multivariate stepwise logistic regression analysis was performed to estimate the association between AF and various patient characteristics.RESULTS The 29,166 study participants included 13,253 men(45.4%)and had a mean age of 72.2 years.The 7073 rural participants differed significantly(P≤0.02)from the 22,093 urban participants in several major characteristics,such as older age,greater body mass index,and so on.The overall prevalence of AF was 4.6%(n=1347).AF was more prevalent in 7073 rural participants than 22,093 urban participants(5.6%vs.4.3%,P<0.01),before and after adjustment for age,body mass index,blood pressure,pulse rate,cigarette smoking,alcohol consumption and prior medical history.Multivariate logistic regression analysis identified overweight/obesity(OR=1.35,95%CI:1.17–1.54)in urban areas and cigarette smoking(OR=1.62,95%CI:1.20–2.17)and alcohol consumption(OR=1.42,95%CI:1.04–1.93)in rural areas as specific risk factors for prevalent AF.In patients with known AF in urban areas(n=781)and rural areas(n=338),60.6%and 45.9%,respectively,received AF treatment(P<0.01),and only 22.4%and 17.2%,respectively,received anticoagulation therapy(P=0.05).CONCLUSIONS In China,there are urban-rural disparities in AF in the el
