The Relationship between the Metabolic Syndrome and the Risk of Benign Prostatic Hyperplasia: a Hospital-Based Study from a Health Screening Population / 대한비뇨기과학회지

ABSTRACT

PURPOSE: This case-control study was designed to investigate the possible association of the metabolic syndrome(MS) with benign prostatic hyperplasia(BPH) in healthy males. MATERIALS AND METHODS: We reviewed the data of 702 men who had a general health check-up without significant evidence of disease. The database for health check-ups included demographic, anthropometric, serum-related and prostate-related data. The presence of the MS was determined according to the NCEP-ATPIII criteria. We compared prostate- related data between the MS and the non-MS group. Testing for linear trends and logistic regression were performed to determine whether the presence of the MS was associated with an increased risk for BPH. RESULTS: The MS was identified in 166 men(23.6%). There was an increased prevalence of both the MS and BPH along with increasing age. There was a tendency for the total prostate volume and the PSA to increase along with the an increasing number of factors related to the metabolic syndrome. In a comparison between the MS and non-MS group, there were no differences in the prostate-related variables. However, subgroup analysis in men less than 50 showed significant differences in the PSA, total volume and calculated annual growth rate. In addition, only in this group was the presence of the MS a significant risk factor for BPH(odd ratio; OR=2.21, 95% confidence interval; CI 1.28-4.75). CONCLUSIONS: The results of this study showed a weak but significant relationship between the MS and BPH, especially in men less than 50. Further longitudinal studies with a larger patient population are required to confirm our findings.
