Prevalence of dyslipidemia and associated factors among the hypertensive population from rural Northeast China Chronic Disease epidemiology

Abstract

Background: Our latest study reported the grim status of hypertension in rural China with the prevalence of hypertension reached 51.1 %. However, we lack the latest data about the prevalence and epidemiological features of dyslipidemia among hypertensive residents in rural China. Methods: A cross-sectional survey was conducted from July 2012 to August 2013 through a cluster multistage sampling to a resident group of 4048 individuals (2152 men, 2896 women) with hypertension, age ≥ 35 years, in the rural Northeast China. Serum lipids level were proposed by National Cholesterol Education Program Adult Treatment Panel III. Results: Of the hypertension residents without antihypertension treatment, 34.5 % had borderline high total cholesterol, 19.2 % had high total cholesterol, 11.4 % had low high-density lipoprotein cholesterol and 37.4 % had high non HDL-C. The population with borderline high, high, and very high low-density lipoprotein cholesterol was 20.9, 6.7 and 2.3 %, respectively. In addition, 14.3 % had borderline high triglycerides, 17.4 % had high TG and 2.4 % had very high TG. The awareness rate of dyslipidemia among the study population was 5.9 %. After adjusting for independent variables, fasting plasma glucose, body mass index, Han nationality, current drinking and smoking, higher annual income and classification of blood pressure were risk factors for dyslipidemia while moderate physical activity was protective factor for dyslipidemia. On the contrary, gender and current drinking decrease the risk of HDL-C. Conclusion: The prevalence of dyslipidemia was dramatically high and dyslipidemia screening was in-need in all diagnosed hypertensive individuals.
