Colorectal cancer (CRC) is the third most prevalent cancer and the second most common cause of cancer-related deaths in the United States (USA). Early screening has been demonstrated to improve clinical outcomes for CRC. Assessing patterns in CRC screening utilization is important for guiding policy and implementing programs for CRC prevention and control. This study examines the trends and sociodemographic factors associated with blood stool test utilization (BSTU) for CRC screening in Georgia, USA. The Behavioral Risk Factor Surveillance System (BRFSS) data were analyzed for Average Annual Percent Change (AAPC) in BSTU between 1997 and 2014 among adults aged 50+ who have had a blood stool test within the past two years, and logistic regression analysis of the 2016 data was performed to identify the associated sociodemographic factors. In Georgia, an overall decrease was observed in BSTU, from 27.8% in 1997 to 16.1% in 2014 (AAPC = −2.6, p = 0.023). The decrease in BSTU was less pronounced in Georgia than nationally (from 26.1% in 1997 to 12.8% in 2014 (AAPC = −4.5, p < 0.001)). BSTU was significantly associated with black race/ethnicity (Black vs. White (aOR = 1.43, p = 0.015)), older age (≥70 vs. 50–59 (aOR = 1.62, p = 0.006)), having insurance coverage (no vs. yes (aOR = 0.37 p = 0.005)), and lower income (≥USD 50,000 vs. <USD 25,000 (aOR = 0.70 p = 0.050)). These findings reveal a decrease over time in BSTU in Georgia, with existing differences between sociodemographic groups. Understanding these patterns helps in directing tailored programs for promoting CRC screening, especially among disadvantaged populations.
