Abstract:
PURPOSE: We evaluated the relationship of prostate-specific antigen (PSA) and obesity indices (weight, body mass index [BMI] and waist circumference [WC]) in Korean middle-aged men. MATERIALS AND METHODS: From February to September 2013, 1,900 police men under 60 years old who participated in a prostate health screening program were included this cross-sectional study. All subjects underwent clinical examinations including weight, height, BMI, WC, fasting blood sugar, lipid profiles, estimated glomerular filtration rate (GFR), and PSA. Total prostate volume (TPV) was assessed clinically. Spearman correlation and multiple linear regression tests were performed to evaluate the obesity indices and PSA relationships. RESULTS: The mean age was 52.0±4.7 years, and the mean PSA was 0.97±0.99 ng/mL. The PSA showed a significant positive correlation with the age (r=0.108, p < 0.01), TPV (r=0.349, p < 0.01), height (r=−0.052, p < 0.05), weight (r=0.186, p < 0.05), low-density lipoprotein cholesterol (r=0.056, p < 0.05), and GFR (r=−0.096, p < 0.01). All obesity indices including weight, BMI, and WC showed negative correlations with PSA (beta=−0.013, p < 0.001; beta=−0.039, p < 0.001; and beta=−0.010, p=0.005; respectively) in age and TPV-adjusted model. CONCLUSIONS: Common obesity indices (weight, BMI, and WC) were associated with lower PSA in Korean middle-aged population. Thus, an individual's degree of obesity should be considered when PSA is checked in the first prostate cancer screening of life.
