The association between metabolic syndrome and the National Institutes of Health Chronic Prostatitis Symptom Index: results from 1673 men in China.

OBJECTIVE To investigate the association between metabolic syndrome (MetS) and the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) in a population-based sample of Chinese men. METHODS From October 2010 to July 2011, 1896 men, aged between 20 and 50 years, residing in Shijingshan district of Beijing, China, were selected to participate in the Male Reproductive Health Program (a random cross-sectional survey). The Chinese version of the NIH-CPSI questionnaire was used to identify men with prostatitis-like symptoms. The presence of MetS was determined according to the 2005 National Cholesterol Education Program-Adult Treatment Panel III criteria for Asian Americans. RESULTS Complete data were available for 1673 men. The major domains of NIH-CPSI scores were significantly different among different body mass index (BMI) groups (P < .05). No significant differences were identified in the incidence of prostatitis-like symptoms or each NIH-CPSI scores between patients with MetS and those without MetS. When the age and BMI were adjusted, there was no significant correlation between the components of MetS and each NIH-CPSI scores. CONCLUSION There was no significant correlation between MetS or components of MetS and chronic prostatitis/chronic pelvic pain syndrome. Age and BMI were identified as a risk factor for chronic prostatitis/chronic pelvic pain syndrome. Further studies are necessary to confirm our results. Published by Elsevier Inc.
