We aimed to investigate the prevalence of CAD and its associated factors in urban northern China. Methods: A cross-sectional study was conducted among 29,359 Chinese adults aged ≥20 years. All participants were randomly recruited from two urban communities in Beijing and asked to complete a self-administered questionnaire that enquired about the demographic characteristics as well as the diagnosis of CAD and CAD-related symptoms. Results: In all, 26,166 participants completed the questionnaire, with the response rate being 89.1%. The prevalence of diagnosed CAD was 9.0% among men and 7.2% among women, with a total prevalence of 8.1%. Furthermore, 11.5% of the investigated subjects had CAD-related symptoms. Women had a lower risk of developing wheezing, cough, dyspnea, and diagnosed CAD than men (P Conclusions: CAD is a common respiratory disease in urban northern China. Female gender might be a protective factor against CAD, while age and smoking are risk factors for the disease. UR - https://jtd.amegroups.org/article/view/24911
