  • Cardiometabolic risk factors and obesity: does it matter whether BMI or waist circumference is the index of obesity? American journal of clinical nutrition Abbasi, F., Blasey, C., Reaven, G. M. 2013; 98 (3): 637-640

    Abstract:

    It has been suggested that the cardiometabolic risk associated with excess adiposity is particularly related to central obesity.The objective was to compare the associations between cardiometabolic risk of apparently healthy individuals and measures of central obesity [waist circumference (WC)] and overall obesity [body mass index (BMI)].In this cross-sectional, observational study, 492 subjects (306 women and 303 non-Hispanic whites) were classified by BMI (in kg/m(2)) as normal weight (BMI <25) or overweight/obese (BMI = 25.0-34.9) and as having an abnormal WC (≥80 cm in women and ≥94 cm in men) or a normal WC (<80 cm in women and <94 cm in men). Measurements were also made of the cardiometabolic risk factors: age, systolic blood pressure (SBP), and fasting plasma glucose (FPG), triglyceride, and high-density lipoprotein (HDL)-cholesterol concentrations. Associations among cardiometabolic risk factors and BMI and WC were evaluated with Pearson correlations.There was a considerable overlap in the normal and abnormal categories of BMI and WC, and ∼81% of the subjects had both an abnormal BMI and WC. In women, BMI and WC correlated with SBP (r = 0.30 and 0.19, respectively), FPG (r = 0.25 and 0.22, respectively), triglycerides (r = 0.17 and 0.20, respectively), and HDL cholesterol (r = -0.23 and -0.20, respectively) (P < 0.01 for all). In men, BMI and WC also correlated with SBP (r = 0.22 and 0.22, respectively), FPG (r = 0.22 and 0.25, respectively), triglycerides (r = 0.21 and 0.18, respectively), and HDL cholesterol (r = -0.20 and -0.13, respectively) [P < 0.05 for all, except for the association of WC with HDL cholesterol (P = 0.08)].Most individuals with an abnormal BMI also have an abnormal WC. Both indexes of excess adiposity are positively associated with SBP, FPG, and triglycerides and inversely associated with HDL cholesterol.
