| Objective: 1.Study the prevalence and influencing factors of atrial fibrillation in the community of Hohhot,and understand the epidemic characteristics of the disease in the population;2.Explore the awareness rate and anticoagulation treatment rate of community residents on the prevention and treatment of atrial fibrillation,aiming to provide a basis for comprehensive prevention and treatment of atrial fibrillation.Methods: From December 2021 to October 2022,a simple random sampling combined with cluster sampling method was used to select permanent residents aged 18 and above from communities in Xincheng District,Huimin District,Saihan District,and Yuquan District of Hohhot City as the survey subjects,with a total of 1725 people.All participants completed the questionnaire survey and received physical examination and ECG examination for statistical analysis.Results: 1.A total of 1725 people aged ≥ 18 years were investigated,with an average age of 53.25 ± 16.23 years,including 719(41.7%)males,1006(58.3%)females,1616(93.7%)Hans and 76(4.4%)Mongols.Among them,there were 30 patients with atrial fibrillation,with a prevalence rate of 1.74%.The average age of patients with atrial fibrillation is(53.00 ±16.23)years old,mostly 27(90.0%)Han Chinese.The incidence of atrial fibrillation in males is higher than that in females(2.50% vs 1.19%),with the most patients in the age group of60-69 years old and 70-79 years old(13 people,43.3%);The results of single factor analysis showed that age,hypertension,diabetes,hyperlipidemia,and alcohol consumption had significant differences in the prevalence of atrial fibrillation(P<0.05);Binary logistic regression analysis showed that the main risk factors for atrial fibrillation were age(OR=1.064,95% CI: 1.029-1.100),hypertension(OR=2.329,95% CI: 1.044-5.194),and alcohol consumption(OR=3.061,95% CI: 1.284-7.300).The study did not find heart failure and smoking as risk factors for atrial fibrillation.2.There were 20 cases of hypertension complicated with atrial fibrillation,including 7 cases of grade 1 complicated with atrial fibrillation,4 cases of grade 2 complicated with atrial fibrillation,and 9 cases of grade 3complicated with atrial fibrillation.There was a statistically significant difference in the incidence of atrial fibrillation among each group(P<0.05);The pairwise comparison of inter group rates suggests that there is a statistically significant difference in the incidence of atrial fibrillation between the second level group and the first level group(P<0.05),while the incidence of atrial fibrillation between the third level group and the second level group is statistically significant(P<0.05).3.Among the 1725 respondents,215 had basic knowledge about atrial fibrillation,with a total awareness rate of 12.5%.Comparing the awareness rate of atrial fibrillation knowledge among residents of different ages and educational backgrounds,univariate analysis showed that there was no statistical difference in the distribution between different age groups(P>0.05);The awareness rate of basic knowledge of atrial fibrillation among graduate students and those with bachelor’s degrees is higher than that of other groups,and the difference is statistically significant(P<0.05).4.Among 30 patients with atrial fibrillation,9 patients(30%)received regular oral anticoagulant therapy,9 patients(30%)received oral ventricular rate control medication,2 patients(7%)received oral rhythm control medication,1 patient(3%)received both rhythm control and anticoagulant medication,1patient(3%)received both ventricular rate control and anticoagulant medication,and 8patients(27%)did not receive medication.The total anticoagulant treatment rate was only32%.Conclusion: 1.The prevalence rate of atrial fibrillation among residents aged 18 and above in the community of Hohhot City is 1.74%,slightly higher than the recent total prevalence rate of atrial fibrillation among residents nationwide.The overall age is older and there is a significant gender difference;2.The prevalence rate of atrial fibrillation in Hohhot community is related to age,hypertension,diabetes,hyperlipidemia and alcohol consumption,among which age,hypertension and diabetes are risk factors for atrial fibrillation;3.The higher the blood pressure level,the greater the risk of concomitant atrial fibrillation,and the blood pressure level may be a risk factor affecting the onset of atrial fibrillation;4.The awareness rate of atrial fibrillation prevention and treatment knowledge and anticoagulation treatment rate among community residents in Hohhot city is very low.The awareness rate of atrial fibrillation knowledge in the community is related to the education level of the residents,and the overall education level is higher,and the awareness rate is higher;It is necessary to strengthen the promotion and education of knowledge on the prevention and treatment of atrial fibrillation in the region,in order to better prevent and treat atrial fibrillation. |
