Estimated risk of coronary heart disease in obese adult males in Northern Jordan

OBJECTIVE: To examine the relationship between obesity, lipid profile and blood pressure, and to quantify the risk of coronary heart disease (CHD) for the next 10 years, using the Framingham risk scoring scheme among Jordanian adult males.

METHODS: We conducted this study in Al-Sarieh, Jordan during the period March to May 2001. A total of 306 apparently healthy adult males, aged 30-50 years completed all the study procedures. We selected the participants using a multi-stage cluster sampling design. Dietary history and smoking habits were obtained using a pre-tested questionnaire and interview. Blood samples were obtained and examined for lipid profiles. We measured the blood pressures, as well as the weight and height to calculate the body mass index (BMI). The sample was categorized into 3 groups using the World Health Organization classifications for BMI. The risk of CHD was calculated using a scoring scale according to Framingham scheme. Analyses of data were carried out using the Chi-square test, and the Analysis of Variance.

RESULTS: The mean age of the subjects was 39 years with a mean BMI of 28.2 kg/m2. The percentage of current smokers was 44.1%. The mean of serum total cholesterol, triglycerides, low density lipoprotein cholesterol and systolic blood pressure, increased significantly with increasing BMI categories, whereas the mean of high density lipoprotein cholesterol decreased with increasing BMI categories. Prevalence of medium and high risk of CHD significantly increased as BMI categories increases.

CONCLUSION: The prevalence of estimated CHD risk for the next 10 years in moderate and high CHD categories increases as the BMI categories increases among Jordanian adult men in Al-Sarieh area.
