Abstract：Objective To learn the prevalence and influencing factors of dyslipidemia among the residents aged 35-75 years in Zhejiang Province, so as to provide basis for prevention and control of dyslipidemia. Methods Based on the national high-risk early screening and comprehensive intervention program for cardiovascular disease, multi-stage stratified cluster sampling method was adopted to select 35-75 year-old permanent residents from six cities （counties or districts） in Zhejiang Province. A questionnaire survey was used to collect demographic data;physical examination and laboratory test were carried out. A multivariate logistic regression model was used to analyze the influencing factors for dyslipidemia. Results A total of 44 440 residents were investigated and 40 751 residents responded,accounting for 91.70%. The crude prevalence rate of dyslipidemia was 36.88% （15 027 cases） and the age-standardized one was 34.58%. The crude prevalence rates of hypercholesterolemia, hypertriglyceridemia and high low density lipoprotein-cholesterol were 18.10%, 14.05%, 10.57% and 15.78%, respectively,the age-standardized ones were 16.11%, 13.76% and 14.53%, respectively.The results of multivariate logistic regression analysis showed that age （OR=1.006, 95%CI:1.004-1.008）,urban residence （OR=1.139, 95%CI: 1.087-1.194）,smoking （OR=1.099, 95%CI: 1.033-1.170）,drinking （OR=0.915,95%CI: 0.863-0.970）,underweight （OR=0.623, 95%CI: 0.528-0.735）, overweight （OR=1.624,95%CI: 1.552-1.699）, obesity （OR=2.128, 95%CI: 1.985-2.281）, diabetes （OR=1.600, 95%CI: 1.493-1.715）, hypertension （OR=1.218, 95%CI: 1.165-1.273） and hyperurcemia （OR=1.789, 95%CI: 1.679-1.905） were associated with dyslipidemia. Conclusions The age-standardized prevalence rate of dyslipidemia among the residents aged 35-75 years in Zhejiang Province was lower than that in the whole country,but the prevalence rates of hypercholesterolemia,hypertriglyceridemia and high low density lipoprotein-cholesterol were relatively high.
