The prevalence of coronary risk factors in Iranian lor migrating tribe.

Cardiovascular diseases are the major causes of death in Iran. The aim of this study was to determine the prevalence of conventional risk factors for coronary artery disease in Lor migrating tribes in southern part of Iran. Two hundred six persons of Lor migrating tribes in Mamasani, southern Iran (age range, 21 - 80 years) were randomly enrolled in the study. Their serum total cholesterol, triglyceride, high- density lipoprotein, low- density lipoprotein, and fasting blood sugar were determined. Of the participants, 79.9% were smokers. The prevalence of hypertension was 37.4% (mostly grade 1), 3.6% had diabetes mellitus, and 14.7% had impaired fasting glucose. A cholesterol level of more than 240 mg/dL was found in 7.1% of the participants, 27.8% had a low-density lipoprotein level of more than 130 mg/dL, 38.9% had a high-density lipoprotein level of less than 40 mg/dL, and 25.2% had a triglyceride level of more than 200 mg/dL. Body mass index greater than 25 was found in 34.8% of the participants, and 57.1% had intermediate and high risk for coronary events. The prevalence of conventional risk factors for coronary artery disease in Lor migrating tribes in comparison with Tehran urban population was very high.
