ABSTRACT
Cardiovascular diseases are the most common cause of mortality and morbidity in new societies. Dyslipidemia is one of the main causes of coronary artery disease. Since there is not comprehensive information about this subject, we aimed to survey dyslipidemia in urban and rural communities/areas in Semnan province. An epidemiologic cross-sectional study was conducted among 3799 persons who were 30-70 years old in Semnan Province, Iran. Multistage cluster sampling was performed, and subjects were selected from urban and rural populations of Semnan, Shahroud, Garmsar and Damqan. Data were collected through questionnaires, then a blood sample was collected from selected patients with 12 hours fasting for evaluation of triglyceride [TG], cholesterol, high density lipoproteins [HDL] and low density lipoproteins [LDL] levels in urban and rural communities. Totally, 3799 persons enrolled in this study with mean age 41 +/- 10.2 years that 44.6% of them were male. High TG was seen in 29.1%, high LDL in 11.8% and low HDL in 30.7%. Prevalence of all kinds of dyslipidemia was higher in Shahroud. In conclusion, prevalence of dyslipidemia among 30-70 years old was higher than expected. So that, comprehensive preventive and educational programmes on lipid disorders and related diseases are necessary
