Why the study?
Does obesity significantly affect serum prostate specific antigen levels such that adjustment for body mass index is warranted?
Does obesity significantly affect serum prostate specific antigen levels such that adjustment for body mass index is warranted?
Adjusting prostate specific antigen for body mass index is not clinically warranted despite a small inverse relationship between obesity and PSA.
Consistent with prior studies, we found an inverse relationship between obesity and serum prostate specific antigen. However, the magnitude of the difference was small. Thus, adjusting prostate specific antigen for body mass index does not appear warranted.
