ABSTRACT
Background: Screening rates for colorectal cancer [CRC] are increasing nationwide including Tennessee [TN]; however, their up-to-date status is unknown. The objective of this study is to determine the trends and characteristics of TN adults who are up-to-date status with CRC screening during 2002-2008
Methods: We examined data from the TN Behavioral Risk Factor Surveillance System for 2002, 2004, 2006 and 2008 to estimate the proportion of respondents aged 50 years and above who were up-to-date status with CRC screening, defined as an annual home fecal occult blood test and/or sigmoidoscopy or colonoscopy in the past 5 years. We identified trends in up-to-status in all eligible respondents. Using multivariable logistic regression models, we delineated key characteristics of respondents who were up-to-date status
Results: During 2002-2008, the proportion of respondents with up-to-date status for CRC screening increased from 49% in 2002-55% in 2006 and then decreased to 46% in 2008. The screening rates were higher among adults aged 65-74 years, those with some college education, those with annual household income >/=$35,000 and those with health-care access. In 2008, the respondents who were not up-to-date status with CRC screening included those with no health-care coverage [adjusted odds ratio [OR] 0.46, 95% confidence interval [CI] 0.33-0.63], those aged 50-54 years [OR 0.62, 95% CI 0.46-0.82] and those with annual household income <$25,000 [OR 0.65, 95% CI 0.52-0.82]
Conclusions: TN adults who are up-to-date status with CRC screening are increasing, but not across all socio-demographic subgroups. The results identified specific subgroups to be targeted by screening programs, along with continued efforts to educate public and providers about the importance of CRC screening
