RESUMO
Objective:To investigate the risk factors of cardiovascular diseases and related epidemic characteristics in the elderly in Guangxi, so as to provide basis for the prevention and treatment of cardiovascular diseases.Methods:Adopting cluster-based stratified sampling, permanent residents over 60 years old meeting one of the following criteria were enrolled in this study: Disease history of myocardial infarction, percutaneous coronary intervention, coronary artery bypass surgery, stroke.Hypertension, dyslipidemia; Ten-year cardiovascular disease risk ≥20%.Results:(1)Among 68, 324 respondents, 29, 542(43.2%)were males and 38, 782(56.8%)were females; 20999 high-risk subjects were detected, including 9486 males(32.1%)and 11513 females(29.7%); (2)The prevalence of hypertension was 50.2%(male 51.20%, female 49.4%, P<0.05); The prevalence of diabetes mellitus was 24.1%(male 24.1%, female 24.1%, P>0.05, ); (3)The smoking rate was 14.0%(male 32.1%, female 0.1%, P<0.05); (4)The overweight rate was 42.2%(male 44.6%, female 40.4%, P<0.05); obesity rate was 9.0%(male 8.6%, female 9.3%, P<0.05)(5)The mean total cholesterol level was 4.70 mmol/L(4.49 mmol/L for men, 4.90 mmol/L for women, P<0.05), the mean low density lipoprotein cholesterol was 2.73 mmol/L(2.63 mmol/L for males, 2.82 mmol/L for females( P<0.05). Conclusions:The detection rate of cardiovascular high risk subjects in Guangxi is 30.7%.The prevalence rate of hypertension and smoking in Guangxi are lower than that in the whole country; The control rate of diabetes in the elderly in Guangxi is generally low.The overweight rates of the elderly in Guangxi are higher in males than in females, but the obesity rate of females is higher than that of males; The levels of TC and LDL-C in elderly females in Guangxi were significantly higher than those in males.
