Abstract: Objective To analyze the electrocardiogram results of occupational health examination for employees and explore the related factors of abnormal electrocardiogram,in order to provide a basis for preventing cardiovascular disease. Methods From January to December 2022,convenience sampling was used to select employees who underwent health examination in one secondary hospital （Feidong Hospital of Traditional Chinese Medicine） and one tertiary hospitals （Feidong County People's Hospital） in Feidong County for this study. The electrocardiogram examination reports,physical examination results,and laboratory indicators of the respondents were collected,and a questionnaire survey was conducted. The descriptive analysis method was used to analyze the abnormal situation of electrocardiogram in this population,and the univariate and multivariate analysis methods were used to analyze the related factors. Results A total of 10 828 employees participated in this study,including 5 848 males （54.01%） and 4 980 females （45.99%）. A total of 10 828 electrocardiograms were recorded,and 1 458 abnormal electrocardiograms were detected,with a detection rate of 13.47%. The results of univariate analysis showed that age,hospital grade,smoking,alcoholism,hypertension,hyperglycemia,hyperlipidemia,BMI,healthy diet,exercise,working years,working hours,and work stress were associated with abnormal electrocardiogram of employees （all P<0.01）. The results of multivariate logistic regression analysis showed that age （OR=4.604 for 50-60 years old）,smoking （OR=4.154）,alcoholism （OR=3.725）,hypertension （OR=2.433）,BMI （OR=3.747 for overweight/obesity）,exercise （OR=0.232 for sufficient exercise）,working years （OR=6.197 for ≥31 years）,working hours （OR=4.595）,and work stress （OR=4.513） were all influencing factors for abnormal electrocardiogram in employees. Conclusions In Feidong region,the abnormal electrocardiogram detection rate is high in employees,which is related to age,smoking,and other factors. Regular physical examination and targeted health management have a positive effect on the prevention of cardiovascular diseases in this population.
