Characteristics of high-risk cardiovascular disease among residents aged 35-75 in 8 districts of Beijing

Abstract

Objective: To understand the characteristics and current situation of high risks related to cardiovascular disease among residents aged 35-75 in Beijing and to provide scientific reference for the formulation and improvement of cardiovascular disease prevention and control strategies and measures. Methods: According to the data of the Cardiovascular Disease Screening and Management Program in Beijing, 93 520 participants aged 35-75 in 8 districts of Beijing were selected for analysis. We used the χ2 test to compare the high-risk prevalence of cardiovascular disease in different population characteristics. The multivariate logistic regression model was used to analyze the relationship between population characteristics and the high risks of cardiovascular disease. Results: The prevalence of high-risk cardiovascular disease was 20.82% (19 471/93 520). The prevalence of high-risk population in the 65-75 years-old was significantly higher than those of other age groups [29.05% (5 151/17 733), χ2=3 359.37, P<0.001], and the prevalence increased with age (trend χ2=3 121.75, P<0.05). The prevalence of high risk in males was significantly higher than that of women (31.19%, 10 752/34 476 vs. 14.77%, 8 719/59 044, χ2=3 559.87, P<0.05). The most common clustered risk factors appeared as hypertension and diabetes (29.80%, 5 802/19 471), hypertension with smoking (37.84%, 4 069/10 752) in males, and hypertension with diabetes mellitus in females (49.32%, 4 300/8 719), in urban areas (33.62%, 2 571/7 647) and in suburbs (27.33%, 3 231/11 824). Lower education [high school (OR=1.56,95%CI:1.46-1.66), middle school (OR=1.99,95%CI:1.88-2.12), primary school and below (OR=2.28,95%CI:2.12-2.45)], non-Han ethnicity (OR=1.19, 95%CI: 1.07-1.33), unmarried (OR=1.16, 95%CI: 1.08-1.24), drinking alcohol (OR=3.06, 95%CI: 2.94-3.19), obesity (OR=1.85, 95%CI: 1.77-1.93), overweight (OR=1.41, 95%CI: 1.36-1.47), etc., were positively correlated with the high risk of cardiovascular disease. Conclusions: We noticed that the prevalence of high-risk groups of cardiovascular disease aged 35-75 years was around 20% in Beijing, and the proportion in males was higher than females. Low education, drinking, overweight, and obesity were positively correlated with the risks of cardiovascular disease.
