title: Prevalence of and risk factors for prostatitis in African American men: the Flint Men's Health Study.
abstract: BACKGROUND
  Prostatitis is a common, yet ill-defined condition without clear diagnostic criteria and treatment strategies. Previous studies examining the prevalence and correlates of prostatitis are limited in their inclusion of primarily white populations. The objective of the current study was to identify prevalence of and risk factors for prostatitis in a population-based sample of African-American men.
  
  
  METHODS
  In 1996, a probability sample of 703 African-American men, aged 40-79, residing in Genesee County, Michigan without a prior history of prostate cancer/surgery provided responses to a structured interview-administered questionnaire which elicited information regarding sociodemographics, current stress and health ratings, and past medical history, including history of physician diagnosed prostatitis, BPH and sexually transmitted diseases. Logistic regression was used to identify predictors of prostatitis after adjustment for age.
  
  
  RESULTS
  Forty-seven (6.7%) of the 703 men reported a history of prostatitis. Increased frequency of sexual activity and physical activity were significantly associated with decreased odds of disease. Moderate to severe lower urinary tract symptoms (LUTS) and a history of BPH were significantly associated with prostatitis after adjustment for age.
  
  
  CONCLUSIONS
  After adjustment for age, LUTS severity and history of BPH were associated with increased odds of prostatitis. BMI, physical activity and sexual frequency were associated with decreased odds of prostatitis. Finally, poor emotional and physical health, high perceived stress and low social support were associated with an increased risk of prostatitis history. Importantly, these findings suggest that the primary risk factors for this condition are largely modifiable and highlight potential targets for future prevention.
