Risk factors and risk assessment of ASCVD in occupational population in Xi'an / 中国医师杂志

ABSTRACT

Objective:To investigate the atherosclerotic cardiovascular disease (ASCVD) risk and blood lipid level of occupational population in Xi'an and to provide reference for the prevention and treatment of cardiovascular diseases.Methods:Data of employees who came from 35 organizations and underwent physical examination in Xi'an city from March to December 2019 in Shaanxi Provincial People's Hospital were collected through cross-sectional investigation to evaluate ASCVD risk factors and compare their blood lipid level.Results:⑴ There were 8 806 subjects, including 7 104 males and 1 702 females. The highest risk factor exposure rates were overweight/obesity and smoking, accounting for 56.0% and 54.1%, respectively. The proportion of dyslipidemia was triglycerides (TG) (42.8%), total cholesterol (TC) (29.0%), high-density lipoprotein cholesterol (HDL-C) (16.2%) and low-density lipoprotein cholesterol (LDL-C) (16.1%). ⑵ According to the ASCVD risk assessment, the proportion of low risk, median risk and high risk were 77.7%, 12.9% and 9.4%, respectively. ASCVD risk was higher in men than in women, and the age ≥40 years group was higher than that of the age < 40 years group (all P<0.05). There were 530 cases taken risk assessment for rest of life, among which 283 cases were at high risk, accounting for 53.4%. ⑶ The average LDL value was (2.69±0.74)mmol/L, with a compliance rate of 78.4%. The average non-HDL value was (3.50±0.92)mmol/L, and the compliance rate was 70.1%. There was no significant difference in LDL and non-HDL compliance rates not only between the ASCVD risk groups, but also between the high-risk group and the non-high-risk group ( P>0.05). Conclusions:The occupational population in Xi'an has a large proportion of exposure to ASCVD risk factors, about 1/4 of which are ASCVD high-risk, and a better lipid control is expected to reduce the 10-year risk of ASCVD incidence.
