Basic information, questionnaire responses, physical examinations, and laboratory tests of each participant were researched, and documented. Participants were categorized into CHD group and non-CHD group. Multivariate logistic regression was utilized to evaluated the relationships between associated factors and CHD.Results: The prevalence of self-reported CHD was 2.56%, 3.97% among men and 1.69% among women. In multivariate logistic regression analysis, older age (41– 65 years: OR: 7.37, 95% CI: 4.56– 11.94; > 65 years: OR:17.88, 95% CI: 11.02– 29.01), female sex (OR: 0.40, 95% CI: 0.36– 0.44), education (sedentary level: OR: 0.88, 95% CI: 0.79– 0.97; high level: OR: 0.74, 95% CI: 0.63– 0.87), family annual income (10,000– 50,000 yuan: OR: 0.68, 95% CI: 0.60– 0.77; > 50,000 yuan: OR: 0.71, 95% CI: 0.62– 0.82), recently drinking habits (2– 4 times /month: OR: 0.75, 95% CI: 0.63– 0.90; 2– 3 times/week: OR: 0.69, 95% CI: 0.56– 0.86; > 4 times/week: OR: 0.72, 95% CI: 0.63– 0.83), obesity (OR: 1.17, 95% CI: 1.07– 1.28), central obesity (OR: 1.51, 95% CI: 1.33– 1.71), hypertension (OR: 1.60, 95% CI: 1.43– 1.80), dyslipidemia (OR: 0.90, 95% CI: 0.83– 0.98), diabetes mellitus (OR: 2.02, 95% CI: 1.85– 2.19), stroke (OR: 1.42, 95% CI: 1.24– 1.63), family history (CVD: OR: 4.48, 95% CI: 4.00– 5.01; stroke: OR: 1.83, 95% CI: 1.58– 2.12) were associated with CHD (P < 0.05).Conclusion: These findings highlight growing concerns regarding the escalating rates of CHD. Implementing multifaceted, population-based interventions is crucial to mitigate the burden of cardiovascular conditions.Clinical Trial Registry Number: The study received approval from the Ethics Committee of Tianjin Chest Hospital (approval number: 2018KY-003-01). Written informed consent was obtained from all survey participants.Keywords: coronary heart disease, hypertension, diabetes, smoking
