Abstract:
BACKGROUND: The metabolic risks associated with obesity are closely correlated with a central rather than a peripheral fat pattern. These complications of obesity have been attributed to increase in visceral adipose tissue. The aim of this study was to investigate whether the dual- energy X-ray absorptiometry (DEXA) method offers a good alternative to computed tomography (CT) for the prediction of visceral fat in the obese women in correlation of metabolic complication markers. METHODS: The design is a cross-sectional analysis. Total body fat and truncal fat amounts were measured by using DEXA, while total abdominal fat area was measured by CT, and divided into visceral abdominal fat area and subcutaneous fat area. Partial correlation after controlling for age and multiple regression analyses after adjusting for age and total percent body fat were performed to relate the metabolic variables to the CT and DEXA body composition variables. RESULTS: For serum uric acid, total abdominal fat area by CT had the largest R2 values (R2=0.259). For AST, ALT, total cholesterol and log triglyceride, visceral fat area had the largest R2 values (R2= 0.360, 0.407, 0.147, and 0.339), respectively, and for log insulin, truncal fat by DEXA had the largest R2 values (R2=0.275). CONCLUSION: Truncal fat amount measured by DEXA had a strong correlation with visceral fat area measured by CT. Truncal fat amount measured by DEXA and correlated significantly with visceral abdominal fat area measured by CT reflected most of the metabolic complication markers.
