Abstract

I





ntroduction: Pervious studies suggested that obesity is correlated with dyslipidemia, hypertension and diabetes mellitus and it has been known as a main cardiovascular diseases risk factor. Obesity can be defined with Body Mass Index (BMI), Waist-to-Hip Ratio (WHR) and Waist Circumference (WC). The present study shows the prevalence of obesity and abdominal obesity and also their contemporaneity with other risk factors in Yazd 20 – 74 years old citizens.
Materials and Methods:This descriptive study was performed in the year 2005 at Cardiology Reserch Center, Yazd on 2000, 20-74 years old Yazd urban population (phase I Yazd healthy heart project) by cluster sampling. Weight, height, WC and hip circumference (HC) measured by trained health providers and also BMI (weight / height2) and WHR (waist / hip) computed. WC was defined as the distance around the smallest area below the rib cage and above the umbilicus. WHR was achieved by dividing WC to greatest hip circumflex.
Results: In this study the prevalence of overweight (BMI: 25- 29/9 kg / m2) and obesity (BMI >= 30 kg / m2) was 35.7%, 16.3%, respectively. The results showed a significant relationship between BMI and mean total cholesterol, TG, LDL-C (p= 0.00). Also hyperlipidemia, HTN and diabetes mellitus were significantly more prevalent in obese cases and subjects with abdominal obesity (p= 0.00). On the other hand inverse relationship was seen between obesity and abdominal obesity with smoking level of education. Also BMI increased with aging except in ages over 65 that obesity prevalence decreased.
Conclusion:The prevalence of obesity and its association with other CVD risk factors in Yazd urban population were significant. So interventional programs for lifestyle changes and control of obesity should be the major hygienic priorities in Yazd.
