The relationship between weight and CVD risk factors in a sample population from central Iran (based on IHHP)

   BACKGROUND: Atherosclerosis is one of the leading causes of mortality all around the world. Obesity is an independent risk factor for atherosclerosis and cardiovascular diseases (CVD). In this respect, we decided to examine the effect of the subgroups of weight on cardiovascular risk factors.    METHODS: This cross-sectional study was done in ۲۰۰۶ using the data obtained by the Iranian Healthy Heart Program (IHHP) and based on classification of obesity by the World Health Organization (WHO). In this study, the samples were tested based on the Framingham risk score, Metabolic Measuring Score (MMS) and classification of obesity. Chi-square and ANOVA were used for statistical analysis.    RESULTS: ۱۲۵۱۴ people with a mean age of ۳۸ participated in this study. ۶.۸% of women and ۱۴% of men had university degrees (higher than diploma). Obesity was seen in women more than men: ۵۶.۴% of women and ۴۰% of men had a Body Mass Index of (BMI) ≥ ۲۵ Kg/m۲. ۱۳% of the subjects had FBS > ۱۱۰ and۱۳.۹% of them were using hypertensive drugs. In this study, we found that all risk factors, except HDL cholesterol in men, increased with an increase in weight. This finding is also confirmed by the Framingham flowchart for men and women.    CONCLUSION: One of every two Americans, of any age and sex, has a Body Mass Index of (BMI) ≥ ۲۵ Kg/m۲. Obesity associated CVD and other serious diseases. Many studies have been done in different countries to find the relationship between obesity and CVD risk factors. For example, in the U.S.A and Canada they found that emteropiotic parameters, blood presser and lipids increased by age(of both sexes). Moreover, another study done in China, which is a country in Asia like Iran, shows that BMI has an indirect effect on HDL cholesterol, LDL cholesterol and triglyceride. This data is consistent with the results of the current study. However, In China they found that this relationship in men is stronger than women, but our study reveals the opposite.   Keywords: Body Mass Index (BMI), Overweight, Cardiovascular Risk Factors, Framingham Risk Score, Metabolic Syndrome.
