Prevalence of prostatitis-like symptoms in Singapore: a population-based study

To study the prevalence of prostatitis-like symptoms in a generally healthy population.

A population-based cross-sectional survey was conducted in Singapore to evaluate "prostatitis-like symptoms" (PS), lower urinary tract symptoms (LUTS),erectile dysfunction (ED), and quality of life (QoL). Respondents with pain or discomfort in the perineum, testicles, tip of penis or bladder/suprapubic region were identified as having prostatitis-like symptoms.

Altogether, 1087 males aged 21 to 70 were evaluated. While at least 20% of them had some degree of LUTS, only 2.67% (29 out of 1087) had pain or discomfort suggestive of prostatitis. Six men had pain in the bladder or suprapubic region, two in the perineum, six at the tip of penis and 26 had pain during micturition (11 subjects had more than one location of pain). Only two men had severe pain while seven had moderate and the rest had mild pain. The mean age of subjects with PS was 43.14. In terms of racial distribution, 2.23% (18) of Chinese, 3.15% (4) of Malay, 4.49% (4) of Indians and 12.12% (3) of other ethnic origin had PS. Those who had PS had worse erectile function (International Index of Erectile Function (IIEF) 11.92 vs. 17.16, p < 0.003) and a worse QoL score (2.96 vs. 1.38, p < 0.001) than those without PS. Those with PS were more bothered and worried about their symptoms.

The prevalence of prostatitis-like symptoms in a largely Chinese population is 2.67%. Prostatitis-like symptoms have a negative impact on the quality of life and erectile function.
