Serum lipid levels and prevalence of dyslipidemia in adults in Anhui, 2013

Objective To understand the level of serum lipids and the prevalence of dyslipidemia in adults in Anhui province, and provide evidence for the prevention and control of dyslipidemia. Methods On the basis of China Non-communicable and Chronic Disease Risk Factor Surveillance in Anhui in 2013, multi-stage stratified cluster random sampling survey was conducted, the levels of total cholesterol (TC), triglyceride(TG), low density lipoprotein-cholesterol (LDL-C) and high density lipoprotein-cholesterol (HDL-C) of 7120 adults selected were detected by using their fasting blood samples, and stratified weighted adjusting the complex sampling design were used for statistical analysis. Results The prevalence of dyslipidemia in the adults was 29.56%, with 34.91% in males and 24.26% in females. The dyslipidemia prevalence increased in males but decreased in females with age (2=13.907,P=0.000; 2=73.366, P=0.000). The overall levels of serum TC, TG, LDL-C and HDL-C were 4.53, 1.43, 2.73 and 1.39 mmol/L, respectively. The levels of serum TG in males increased with the increase of education level (t=5.938, P=0.000), while HDL-C reversed (t=-12.641, P=0.000). The levels of serum TC, TG and LDL-C in females increased with age (t=10.060, P=0.000; t=12.531, P=0.000; t=8.058, P=0.000), and the four specific serum lipids level varied among different occupations. The prevalence of hypercholesterolemia, hypertriglyceridemia, high blood LDL-C and low blood HDL-C were 5.14%, 12.36%, 5.18% and 16.94%, respectively, and the prevalence of hypercholesterolemia, high blood LDL-C and low blood HDL-C increased with age (2=13.631, P=0.000; 2=14.684, P=0.000; 2=8.893, P=0.003). The prevalence of hypertriglyceridemia and low blood HDL-C increased with the increase of educational level in males (2=40.386, P=0.000; 2=70.480, P=0.000), and the occupation specific prevalence of high blood LDL-C and low blood HDL-C varied (2=28.783,P=0.000; 2=14.687, P=0.040). Conclusion As a risk factor, dyslipidemia was common in adults in Anhui. It is necessary to take targeted prevention and control measures according to the age, gender, educational level and occupation specific prevalence of dyslipidemia in adults.
