OBJECTIVE
Body mass index (BMI) and waist circumference (WC) as measures of obesity have some limitations. This study aimed to evaluate whether one measure could predict the presence of diastolic dysfunction (DD) more accurately than the other measures.

METHODS
Ninety-one obese subjects without any other risk factors for DD were prospectively enrolled. Echocardiographic examination was performed. DD was defined and categorized according to the recent guidelines for heart failure. Subjects were divided into 2 groups according to the presence of DD. Weight, height, and WC were measured; BMI and WHR were calculated; and a body shape index (ABSI) was calculated as WC/(BMI2/3height1/2). We examined the associations of ABSI, BMI, WHR, and WC with the presence of DD by logistic regression analyses. Analysis of Covariance was used to examine the differences.

RESULTS
WC and BMI were significantly increased in subjects with DD (p: 0,049 and 0,051, respectively). Increased BMI, WC, and WHR increased the risk of the presence of DD [BMI-DD: odds ratio (OR) = 1.096, p: 0.024; WC-DD: OR = 1.059, p: 0.007; WHR-DD: OR = 2.363, p: 0.007]. After adjustment for age and sex, only BMI continued to be significantly associated with DD (p: 0.031). ABSI was not associated with DD.

CONCLUSION
After adjustment for age and sex, BMI was the only predictor of DD in obesity. Despite its limitations, BMI could still be a potentially more accurate measure of DD among different obesity measures.
