Association of diet and lifestyle with chronic prostatitis/chronic pelvic pain syndrome and pain severity: A case-control study

Abstract

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common problem with unclear etiology. Some diet and lifestyle factors were thought to correlate with CP/CPPS, but studies comprehensively investigate this correlation are rarely available. The current study was conducted to determine the potential lifestyle-related risk factors of CP/CPPS and its pain severity in Chinese population.Methods:Participants were recruited from seven hospitals in Shanghai from July 2012 to August 2013. Demographics, medical history, diet and lifestyle information, and CP/CPPS symptoms were obtained from each participant using a questionnaire. Univariate and multivariate logistic regression analyses were used to identify potential lifestyle-related risk factors for CP/CPPS and its pain severity.Results:A total of 784 men with CP/CPPS and 785 controls were enrolled in this study. Multivariate regression model indicated that age, nightshift work, stress, smoking status, alcohol consumption, less water intake, imbalanced diet, frequent sexual activity, delaying ejaculation and holding urine were identified as potential risk factors for CP/CPPS, whereas sedentary lifestyle, caffeinated drinks and less water intake were associated with severe pain in CP/CPPS patients.Conclusions:Several diet and lifestyle factors associated with CP/CPPS and pain severity were determined in this study. These modifiable conditions are potential targets for treatment of CP/CPPS. However, further studies are necessary to determine their role in the pathogenesis of CP/CPPS.
