This study aimed to investigate the metabolic syndrome-related risk factors for the development of benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS) in healthy men. A total of 4880 healthy men who underwent transrectal ultrasonography at our hospital during routine health examinations were included in this study. Those who had undergone a prior biopsy or surgery for prostate disease, were suspected of having urinary tract infection, or were taking BPH/LUTS or metabolic syndrome medications were excluded. BPH/LUTS was defined as an International Prostate Symptom Score (IPSS) of >= 8 and a prostate volume (PV) of =30cm(3). The subjects had a mean age of 54.1 years, PV of 29.2 cm(3), prostate-specific antigen (PSA) level of 1.20ng/mL, and IPSS of 9.2. The annual PV growth rate was 0.48cm3/year. Age, body mass index (BMI), PSA, basal metabolic rate, apolipoprotein A-1, fasting blood glucose, high-density lipoprotein (HDL) cholesterol levels were significant predictive factors for PV. Age, PSA, apolipoprotein B, fasting blood glucose, cholesterol, HDL, and low-density lipoprotein (LDL) levels were predictors of BPH/LUTS at the initial health examination. A decreased fat mass and LDL level were a significant risk factor for the development of BPH/LUTS within 5 years in men without a BPH/LUTS diagnosis at the initial examination. Metabolic syndrome-related variables were strongly associated with BPH/LUTS and by decreasing fat mass and LDL levels, development of BPH/LUTS could be prevented within 5 years in healthy Korean men.
