BACKGROUND: Reports have shown that increased serum C-reactive protein (CRP) suggests a risk of lower urinary tract symptoms (LUTS) in the West population. However, few studies have investigated the role of CRP as regards LUTS in a Chinese male population. METHODS: Data were collected from 1,452 men who participated in the population-based Fangchenggang Area Male Health and Examination Survey (FAMHES), which was carried out in Guangxi, China, from September 2009 to December 2009. In the current study, serum CRP was measured with a high-sensitivity method (hsCRP) and LUTS was assessed by International Prostate Symptom Score (IPSS). Meanwhile, information about potential confounding variables (smoking, hypertension, diabetes, etc.) were included. RESULTS: We observed that statistically significant distinction presented in the distribution of hsCRP levels and age between LUTS group and non-LUTS group (P < 0.001). Comparing with the lowest hsCRP tertile, men with the highest hsCRP tertile were 1.72 times more likely to have overall LUTS and 1.93 times more likely to have irritative symptoms. As for individual symptoms of LUTS, statistically significant correlations were noted between serum hsCRP levels and urgency (OR = 1.74, 95% CI = 1.09-2.78) and nocturia (OR = 1.64, 95% CI = 1.18-2.27), when comparing them from the 1st to 3rd hsCRP tertiles. After multivariate adjusted, the results changed slightly and were still significant. CONCLUSIONS: In a Chinese male population, we firstly confirmed a positive correlation of serum hsCRP with LUTS. It can be inferred that inflammation may be involved in the processes of LUTS.
