Epidemiology of Blood Lipid Level Among Rural Groups with Hypertension in Liaoning Province

Aim To investigate the current epidemiological characteristics of blood lipid levels among rural hypertensive patients in Liaoning province and to provide scientific basis for the prevention and treatment of dyslipoproteinemia.Methods A cross-sectional survey was conducted during 2004～2006,through cluster multistage and random sampling to a resident(≥5 years) groups of 6 412 individuals(2,805 men,3,607 women) aged ≥35 years old with hypertension in the countryside of Liaoning province and blood chemical analyses were performed at a central,certified laboratory so as to understand the prevalence of dyslipoproteinemia based on criteria of the prevention and treatment of dyslipoproteinemia in 2006 in China,SPSS11.5 of statistical software was used for data analysis.Results(1)The average level of blood lipids(TC,HDLC,LDLC and TG)had higher levels in hypertensive women than that in hypertensive men(P0.001).(2)The prevalence of isolated hypercholesterolemia(TC≥6.21 mmol/L),low HDLC concentration(HDLC1.03 mmol/L),increased LDLC concentration(LDLC≥4.16 mmol/L),isolated hypertriglyceridemia(TG≥2.26 mmol/L) was 16.9%,8.8%,4.4%,and 19.8%.(3)The prevalence of TC increased with the increased stage of blood pressure and it showed a significant difference among 3 stages.In contrast,the prevalence of HDLC decreased with the increased stage of blood pressure and it was also significant(P0.05);however,we didn't see a trend between LDLC and the stage of blood pressure and TG and the stage of blood pressure.Conclusion The prevalence of dyslipidemia was relatively high among rural hypertensive patients in Liaoning province,it is very important to prevent and control dyslipidemia for us.
