Abstract: Obesity, hypertension and hyperlipidemia are risk factors of atherosclerosis, a major cause of mortality. There haven’t been enough epidemiologic studies on these risk factors, especially in rural populations. 2705 residents of Tehran Province villages, including 1296 (48%) men and 1409 (52%) women, all aged more than 30, were selected by multistage random sampling. Cholesterol, triglyceride and HDL were measured in a fasting blood sample and blood pressure, height and weight were determined. Waist to hip ratio (WHR) was used as an index of abdominal obesity. Women had a higher mean BMI (28.2±5.1) compared with men (25.4±3.9) (P<0.001). 24.3% of studied individuals had moderate to severe obesity. Mean diastolic and systolic blood pressures were 72±12 and 122±12mmHg, respectively and were higher in women. Altogether, 11.1% and 22.2% of individuals had diastolic and systolic hypertension, respectively. Mean triglyceride level was 191±151 with no difference between the sexes. Hypertriglyceridemia was present in 32.7% and hypercholesterolemia in 15.4% of individuals. Mean LDL level was higher in women (129±38.6 mg/dl in women vs. 118±35 mg/dl in men, P<0.001). There was no difference in the prevalence of obesity, LDL to HDL and cholesterol to HDL ratios between men and women. All variables except HDL increase with age. This increased continued to the age of 50 in the case of BMI and WHR, and to the 6th decade for lipids. Lipid and blood pressure levels increased with weight. 12.8% of obese individuals and 8.3% of non-obese individuals had diastolic hypertension. The figures for systolic hypertension in these two groups were 23.5% and 20%, respectively. Hypertriglyceridemia and hypercholesterolemia were seen more commonly in obese (42.5% and 16.5%, respectively) than in non-obese individuals (16.5% and 8.6%, respectively). Considering the remarkable increase in triglyceride, cholesterol, weight and blood pressure in studied individuals, it seems that more extensive studies on environmental factors, especially diet and exercise, and finding suitable solutions to prevent risk factors are necessary.
