Effects of Body Fat and BMI on the Cardiac Risk Factors

ABSTRACT

Choi, D.H. Eom, W.S. Effects of Body Fat and BMI on the Cardiac Risk Factors. Exercise Science. 15(2): 119-126, 2006. This study was to investigate the effects of body fat and BMI on the coronary artery disease(CAD) risk factor. Percent body fat was measured by multi-frequency bioelectric impedance analysis for 883 Korean middle aged male and classified 4 groups by ACSM's guidelines. BMII also classified 3 groups by WHO Asia Pacific Region guideline. We analyzed the frequency on CAD risk factor and predicted body fat and BMII on the CAD risk factor using Logistic regression analysis. The CAD risk factor score was defined as the number of the thresholds for using ACSM' risk stratification. The prevalence of CAD risk factor was 18.6% for under 1 and 81.4% for over 2 or more factors. With Logistic regression analysis, the odds ratio of CAD risk factor for 15% body fat criteria was 1.98, 20% for 2.22, 23% for 2.19 and 25% for 2.63. The odds ratio of CAD risk factor for BMI 23 criteria was 2.01, BMI 25 for 2.94, BMI 30 for 5.66. These means that as the body fat and BMI increase, so does the degree of CAD risk stratification. In summary, it is very important to set the criteria for body fat and BMI for reducing and preventing CAD risk factor. According to our data, BMI 25 was a more valuable cut off point than BMI 23 because BMI 25 criteria can reduced the CAD risk stratification by 46%. In addition, it was very close at odds ratio among the % body fat criteria. Further prospective research in a large and more diverse group is required to determine body fat and BMI cut off point whether the CAD risk factor is associated with epidemiological morbidity and mortality of population.

Key words: CAD risk factor, body fat, BMI
