First, 1086 persons were excluded due to the missing of demographic information or glucose level data. Briefly, 47,325 participants (18,976 men and 28,349 women aged ≥20 years old) from 152 urban street districts and 112 rural villages in 14 provinces completed the study. The details of its sampling methods have been described previously. The China National Diabetes and Metabolic Disorders Study was a population-based cross-sectional study carried out from June 2007 to May 2008. The objective of the present study was to investigate the prevalences of ECG findings in the general population of Chinese adults and determine the associations between ECG abnormalities and age, gender and other CVD risk factors. The ECG data presented in this study were obtained from 34,965 participants in the China National Diabetes and Metabolic Disorders Study from June 2007 to May 2008. Most previous ECG studies performed in China were regional or focused on specific types of ECG findings. To date, no large population study has provided estimates of the prevalences of ECG findings in different age groups in China. ![]() Other CVD risk factors, such as hypertension and diabetes, increased the odds of having major ECG abnormalities and some specific ECG findings. A previous cross-sectional survey reported that arrhythmias accounted for 4.8% in men and 3.6% in women from 65 to 74 years old, while the prevalences of arrhythmias were less than 0.5% in both men and women under 45 years old. Older age has been positively associated with the prevalences of major ECG abnormalities and several specific ECG findings. ![]() The prevalence of major ECG abnormalities has been reported to vary from 6.0 to 11.3% in men and from 4.3 to 12.9% in women in previous studies, with differences dependent on various racial backgrounds and targeted age groups. The prevalences of variant ECG abnormalities and their association with age and CVD risk factors have been reported in several large population studies conducted in North American, South American and European countries. The electrocardiogram (ECG) is an inexpensive and convenient tool that has been widely used to screen arrhythmias and cardiovascular diseases (CVDs). ![]() Gender, age, CVD risk factors and history of cardiovascular/cerebrovascular diseases were significantly associated with ECG abnormalities. This study provides estimates of the prevalences of ECG findings in a large population of Chinese adults. History of cardiovascular/cerebrovascular diseases was positively associated with major arrhythmias, ST depression and T abnormalities and tall R wave left. Hypertension, overweight, obesity and hypercholesterolemia all independently increased the odds of having ST depression and T abnormalities. Independent of gender and other CVD risk factors, older age significantly increased the odds of having atrial fibrillation/flutter, complete left bundle branch block, complete right bundle branch block, sinus tachycardia, atrial/junctional/ventricular premature beats, ST depression and T abnormalities, tall R wave left, left/right atrial hypertrophy, left axis deviation and low voltage. ST depression and T abnormalities accounted for 10.96, 7.54 and 14.32% in the whole population, men and women, respectively. Atrial fibrillation/flutter was found in 0.35% of men and 0.20% of women. The prevalences of major arrhythmias were 1.70, 2.37 and 1.04% in the whole population, men and women, respectively. The associations between ECG abnormalities and gender, age and other risk factors for cardiovascular diseases (CVD) were analyzed by multivariate logistic regression test. Prevalences of variant ECG abnormalities were calculated. ECG abnormalities were classified according to the Minnesota coding (MC) criteria. MethodsĮCG data were obtained from 34,965 participants in the 2007–2008 China National Diabetes and Metabolic Disorders Study. We aim to investigate the prevalences and associated factors of ECG abnormalities in a general population of Chinese adults. ![]() To date, no large population study has provided estimates of the prevalences of ECG findings in China.
