Abstract
|
|
|
Background: The distribution, not only the amount, of body fat is known to affect insulin resistance (IR). We analyzed the risk of IR according to body fat distribution among Korean adults.
Methods: We included from the 2008-2010 Korea National Health and Nutrition Examination Survey database 10,158 adults who had dual-energy X-ray absorptiometry (DEXA) measurements. Each quintile of percent whole body fat (PWBF) and waist circumference (WC) was analyzed using multivariable logistic regression to evaluate the risk of IR.
Results: WC was strongly associated with IR in both sexes. The association was stronger when both PWBF and WC increased simultaneously than when each factor increased individually. In addition, a sex difference in the association between PWBF and IR was demonstrated.
Conclusion: In this sample of healthy Korean adults, WC and PWBF were both positively associated with IR, although the association was stronger for WC.
