Objective: Body mass index (BMI) and waist circumference(WC) as measures of obesity have some limitations. The aimof this study was to evaluate whether one measure couldpredict the presence of diastolic dysfunction (DD) more accurately than the other measures.Methods: A total of 91 obese patients without any other riskfactors for DD were prospectively enrolled. Echocardiographicexamination was performed. DD was defined and categorizedaccording to recent guidelines. The study participants were divided into 2 groups according to the presence of DD. Weight,height, and WC were measured; BMI and waist-to-hip ratio(WHR) were calculated; and a body shape index (ABSI) wascalculated as WC/(BMI2/3height1/2). The associations betweenABSI, BMI, WHR, and WC and the presence of DD were examined using logistic regression analyses. Analysis of covariance was used to examine the differences.Results: WC and BMI were significantly greater in subjectswith DD (p=0.049 and 0.051, respectively). A greater BMI,WC, and WHR increased the risk of the presence of DD (BMIDD: 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 forage and sex, only BMI continued to be significantly associatedwith DD (p=0.031). ABSI was not associated with DD.Conclusion: After adjustment for age and sex, BMI was theonly predictor of DD in obesity. Despite its limitations, BMImay still be a potentially more accurate measure of DD compared with other obesity measures. |
