Abstract:
BACKGROUND: Benign prostatic hyperplasia (BPH) is a common condition in males over 40 years old, and the incidence of BPH has a tendency to increase with age. Obesity is state of excessive accumulation of fat in the body that leads to changes in the body's metabolism and endocrine function. Therefore, progression of BPH occurs in the obese state according to many articles. The purpose of this study was to compare the efficacy of obesity indices which correlate with prostate volume. METHODS: The study was carried out in 285 males, who visited a health promotion center and underwent transrectal ultrasonography and abdominal fat computed tomography from April, 2010 to June, 2013. Anthropometric parameters were measured directly and blood samples were obtained in the morning after over eight hours of fasting. The correlation between obesity indices and prostate volume was analyzed. RESULTS: After adjusting for age, prostate volume was positively correlated with BMI (r=0.227, P<0.001), waist circumference (WC) (r=0.151, P=0.011), waist to height ratio (WHtR) (r=0.149, P=0.012), and visceral fat area (VFA) (r=0.157, P=0.008). However prostate volume showed no correlation with subcutaneous fat area (SFA) and visceral to subcutaneous ratio (VSR). WHtR had the largest area under the curve (AUC) for the identification of prostate volume more than 30 mL (AUC=0.595, P=0.017) followed by VFA and BMI in order. CONCLUSION: Prostate volume was positively correlated with BMI, WC, WHtR, and VFA among the obesity indices and WHtR had the largest AUC followed by VFA and BMI in order.
