Effect of Body Mass Index and Waist Circumference on Prostate Specific Antigen and Prostate Volume in a Generally Healthy Korean Population

Abstract

Obesity had a negative association with prostate specific antigen regardless of prostate volume, and a positive association with prostate volume. Age was not associated with prostate specific antigen after prostate volume adjustment. Obese men, especially those with a small prostate volume, may have lower baseline prostate specific antigen and, thus, be at higher risk for having prostate cancer undetected in a prostate specific antigen screening test.
