Plasma lipids level and related factors in adults in Fenghua,Zhejiang

Objective To learn about the plasma lipids level and related factors among the residents aged ≥18 years in Fenghua.Methods Multistage random cluster sampling were conducted to select study subjects,questionnaire survey,health examination and biochemical detection were performed among the selected subjects.The data were analyzed by t-test,χ2 test and χ2 trend test.The risk factors of dyslipidemia were analyzed by non-conditional logistic regression analysis.Results Totally 600 people aged ≥18 years were surveyed.The average levels of TC,TG,LDL-C and HDL-C were 3.95,1.36,2.25 and 1.02 mmol/L,respectively.The TC,LDL-C and HDL-C levels in females were higher than those in the males(TC: t=-3.216,P=0.001;LDL-C: t=-2.396,P=0.017;HDL-C:t=2.498,P=0.013),the difference had statistical significance.The difference in TG levels between males and females had no statistical significance(t=-1.451,P=0.147).The dyslipidemia rate and borderline dyslipidemia rate were 64.50% and 6.33%,respectively.The age-adjusted standardized dyslipidemia rate and borderline dyslipidemia rate were 45.47% and 4.19%,respectively.The prevalence of dyslipidemia increased with age(χ2trends=13.884,P=0.000).The age-adjusted standardized abnormal rates of TC,TG,LDL-C and HDL-C were 1.53%,6.78%,1.04% and 42.92% respectively.The abnormal rate of HDL-C was higher in males than that in females(χ2=7.181,P=0.007)and increased with age.The risk factors of dyslipidemia included central obesity,aging and overweight or obesity.Conclusion High prevalence of dyslipidemia was found among the residents aged≥18 years old in Fenghua,especially the high abnormal rate of HDL-C.It is necessary to conduct targeted community based dyslipidemia prevention and treatment.
