Waist circumference is a better indicator of cardiovascular (CV) riskthan is body mass index (BMI), according to results from the National Health and Nutrition Examination Survey (NHANES) III published in the September issue of the American Journal of Clinical Nutrition.
“Body fat distribution is a more powerful predictor than is BMI for risk factors, diseases, and mortality,” write ShanKuan Zhu, from Columbia University in New York, N.Y., and colleagues.
“Measurements that are more sensitive to individual differences in abdominal fat might be more useful than BMI for identifying obesity-associated risk factors.” Subjects from NHANES III, which surveyed the non-institutionalized US population from 1988 to 1994, included 4,388 white men with an average age of 44 years and 4,631 white women, average age 47 years. Average BMI was 26, within the overweight category, and average waist circumference was 96.4 cm for the men and 88.2 cm for the women.
