Objective To understand the prevalence of dyslipidemia and related factors in residents of Wenzhou and provide evidence for the development of the prevention and control measure. Methods With multistage random cluster sampling, 3 905 local residents aged 18 years were randomly selected in Ouhai district of Wenzhou for a cross-sectional study, including questionnaire survey, physical examination and laboratory test. Results The average levels of TC, TG, HDL-C and LDL-C (mmol/L) were 5.27, 1.60, 1.37 and 3.19, respectively. The abnormal rates were 18.7%, 17.1%, 14.1% and 15.3%, respectively. The overall prevalence of dyslipidemia was 39.7% and the standardized prevalence of dyslipidemia was 36.0%. The prevalence of borderline dyslipidemia was 28.0% and the standardized prevalence of borderline dyslipidemia was 27.2%. The dyslipidemia rate was higher in males than in females, and increased with age. TC and LDL-C levels increased with the age, the differences in TG and HDL-C levels had no significance among different age groups, the abnormal rate of HDL-C level was higher in males than in females. The abnormal rate of LDL-C level was higher in females than in males. The awareness rate of dyslipidemia related knowledge was 8.1%, the age and gender specific differences had no significance. Logistic regression analysis showed that hyperuricemia, central obesity, diabetes and hypertension were the risk factors for dyslipidemia or related diseases. Conclusion The prevalence of dyslipidemia was high in the residents in Ouhai, but their awareness of dyslipidemia was low.
