Knowledge and opinion on prostate and prevalence of self-reported BPH and prostate-related events : a cross-sectional survey in Italy

Benign prostatic hyperplasia (BPH) is a very common condition in ageing men and causes considerable morbidity. Although great strides have been made recently, important issues remain under-researched and poorly understood. We have conducted a survey on a representative sample of Italian males to investigate the knowledge and opinion on prostate, to estimate the self-reported prevalence and intensity of BPH and LUTS (low urinary tract symptoms) and to evaluate the performance of the International Prostate Symptom Score (I-PSS) in a population-based sample. Trained interviewers administered a standardized questionnaire to a representative random sample of 671 Italian men aged 50 years and over, between May and June 2000. Univariate and multivariate statistical techniques were used to estimate the prevalence of relevant events, and the associations with selected variables. Only half of responders were able to identify the reason for prostate enlargement, less than one-third recently had spoken with a doctor, and only 8.6% had had a rectal examination. Further, 13.7% (95% confidence interval (CI) 11.1-16.3%) had ever been told they had BPH, with less than half of them receiving surgery for BPH. About 19% reported moderate-severe I-PSS. Both self-reported BPH and severe-moderate LUTS increased significantly with age ( -value
