摘要

Many studies have used waist circumference (WC) and hip circumference (HC) to predict abdominal fat distribution. However, most of these studies have focused on the general population. PURPOSE: To determine whether abdominal body circumferences can predict fat distribution. METHODS: Thirty-one individuals (age 31.5±11.4 years, body mass index 23.2±2.2kg/m^2) who had been regular joggers, swimmers and weight lifters for more than 5 years served as the exercise group (EXE). Twelve sedentary persons (age 33.0±6.3 years, BMI 20.5±2.2kg/m^2) were the control group (CON). Magnetic resonance imaging (MRI) was used to determine abdominal fat volume distribution. A non-elastic ruler was used to gauge waist circumference (WC) and hip circumference (HC). The waist-to-hip ratio (WHR) was calculated as the WC divided by HC. RESULTS: The EXE and CON groups' abdominal visceral fat volume were 0.58±0.3L, 0.84±0.3L; abdominal subcutaneous fat volume 2.05±0.9L, 2.22±0.9L; WC 78.6±4.5cm, 77.4±6.3cm; HC 94.2±4.4cm, 91.5±4.4cm; WHR 0.83±0.03, 0.85±0.04, respectively. Abdominal visceral fat volume was significantly correlated with WHR, WC and BMI (0.67, 0.66, 0.51, respectively; p＜0.05). Using stepwise regression, WHR could explain 45% the variance of the abdominal fat volume. When both WHR and BMI entered the regression analysis, the variance explanation could reach 58%. CONCLUSION: The waist and hip circumference can predict the visceral fat volume of people who exercise regularly.
