Among all cases, obese men were more likely than non-obese men to be AA (20 vs. 11 %, p = 0.002), less likely to have a college education (63 vs. 71 %, p = 0.024), presented with higher BMI (26.5 vs. 32.5 kg/m2, p < 0.001) and lower PSA (4.9 vs. 5.3 ng/ml), and more likely to have higher tumor stage (35 vs. 24 %, p = 0.003) and grade (55 vs. 45 %, p = 0.004) at CaP diagnosis (Table 1). This evidence concerns the gene KLK3 and neoplasm.
