Key result
Self-reported CHD affects ~2.6% of Tianjin adults, linked to older age, hypertension, and diabetes.
Why the study?
The prevalence of self-reported coronary heart disease and the influence of varied risk factors on it in Tianjin were not well described.
Cross-Sectional (n=102,576)
Yes
The prevalence of self-reported coronary heart disease in Tianjin is 2.56%, driven largely by traditional cardiovascular risk factors such as older age, hypertension, diabetes, and obesity.
Provides Tianjin CHD prevalence benchmark; supports risk factor links but should not yet change practice.
Objective: To describe the prevalence of self-reported coronary heart disease (CHD) and assess the influence of varied risk factors on it in Tianjin. Methods: This study included a total of 102,576 individuals aged 35 to 75 from 13 community health centers and grassroots hospitals in Tianjin. 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.

He et al. (2024) conducted a cross-sectional in Coronary Heart Disease (n=102,576). Cardiovascular risk factors vs. Absence of risk factors was evaluated on Prevalence of self-reported coronary heart disease. The overall prevalence of self-reported coronary heart disease among adults aged 35 to 75 years in Tianjin was 2.56%, with older age, hypertension, and diabetes identified as significant risk factors.
