title: Assessing colorectal cancer screening knowledge at tribal fairs.
abstract: BACKGROUND
  Increasing public awareness and knowledge about the need for colorectal cancer (CRC) screening among American Indians is key to reducing health disparities. The objective of this study was to assess Navajo adults' knowledge of CRC risk factors and prevention, CRC screening, and self-reported experience with CRC screening.
  
  
  METHODS
  We collected data generated by a self-administered survey given to Navajo adults, most of whom lived on the reservation. Data were collected at 2 annual tribal fairs in 2006. Fair attendees who visited an exhibit booth completed a CRC knowledge survey. The study design was nonrandomized.
  
  
  RESULTS
  Of the 285 Navajo adults who participated, most were bilingual (74%) and female (80%). Of the respondents aged 50 years or older, 77% had heard of CRC screening and 28% reported being screened for colon or colorectal cancer. Knowledge was high (mean, 5.78 [standard deviation (SD), 1.28]) (8.0 was the highest possible knowledge score). Respondents with little or no formal schooling had lower scores (mean, 5.4), indicating less knowledge of CRC and associated screening tests than did those with more education (mean, 6.0).
  
  
  CONCLUSIONS
  Among a sample of Navajo adults aged 50 years or older, participants with more education were more likely to be knowledgeable about CRC and to have received screening. This survey, led by a Navajo investigator with Navajo surveyors, revealed a high awareness of CRC and screening, but overall CRC screening was low. CRC education for Navajo adults who have little or no formal schooling should be improved.
