title: Obesity and prostate cancer screening in the USA.
abstract: OBJECTIVE
  To estimate the association between body mass index (BMI: kg/m2) and prostate-specific antigen (PSA) cancer screening in a nationally representative sample of US men aged 50 years and older using data from the 2001 Behavioral Risk Factor Surveillance Survey.
  
  
  METHODS
  Men aged 50 years or older classified by BMI as healthy weight range (18.5-24.9), overweight (25-29.9), obese class I (30-34.9), obese class II (35-39.9), and obese class III (> or =40).
  
  
  METHODS
  Interval since most recent screening for PSA.
  
  
  RESULTS
  Adjusting for age, race, smoking, education, employment, income and health insurance status, we found that, compared with men in the healthy weight range, men in the overweight [odds ratio (OR)=1.13; 95% confidence interval (95% CI)=1.04-1.35], obese class I (OR=1.26; 95% CI=1.06-1.36) and obese class II (OR=1.14, 95% CI=1.02-1.26) categories were significantly more likely to have obtained a PSA test within the previous year. A similar pattern was observed when we examined other screening intervals (e.g. within past 2 years, within past 3 years, etc.).
  
  
  CONCLUSIONS
  Among men aged 50 years and older, overweight and obesity is associated with obtaining a PSA test.
