Obesity Is Negatively Associated with Prostate-Specific Antigen in U.S. Men, 2001-2004

Abstract

Our population-based, nationally representative results expand the validity of previous studies on obesity and PSA. Higher weight, BMI, waist circumference, triceps skinfold, and total body water are associated with moderately lower PSA values. A prospective study is needed to verify whether this association affects the accuracy of the PSA test in obese men.
