Factors Associated with Colorectal Cancer Screening among Mississippi Adults: Findings from the Behavioral Risk Factor Surveillance System

Abstract

Objectives: Mississippi has one of the highest mortality rates in colorectal cancer (CRC) and one of the lowest rates of CRC screening in the United States. The purpose of the study was to assess the characteristics of Mississippians who met the US Preventive Services Task Force (USPSTF) recommendation on CRC screening and type of the test they used.

Methods: We analyzed the data from the 2018 Mississippi Behavioral Risk Factor Surveillance System (N = 5843), which included a CRC screening module for participants who were 50 years old or older. Respondents in this module were asked when, if ever, they had last undergone a colonoscopy, sigmoidoscopy, or stool occult test. Their responses were then categorized according to their compliance with the USPSTF recommendations on CRC screening. We compared the compliance with responders' sociodemographic and risk factors. Data analysis accounted for the complex sampling design.

Results: The majority of the CRC screening tests are colonoscopies: 60.1% of Mississippians aged 50 to 75 years had received one within 10 years. In addition, 7.8% had taken a stool test within the last year, and 1.9% had undergone sigmoidoscopy within 5 years. The prevalence of individuals aged 50 to 75 in Mississippi who met the USPSTF recommendation for CRC screening in 2018 was 62.6%. Women (65.5%), married (67.5%), those with health insurance (66.5%) or annual household income of ≥$75,000 (71.6%), those with a regular healthcare provider (68.0%), or those who quit smoking (70.4%) had higher compliance than their counterparts. After controlling for the covariates, the adults aged 50 to 75 who had health insurance or had a personal healthcare provider were 2.52 and 2.95 times more likely to be compliant, respectively (P < 0.001). Those who had quit smoking were 2.27 times more likely to be compliant with the USPSTF than current smokers (P < 0.001). Weight status, binge drinking, or physical inactivity was not associated with the CRC screening rates.

Conclusions: Mississippi adults aged 50 to 75 were more likely to be compliant with the CRC screening standards if they had insurance coverage or access to care. To further increase the overall CRC screening rate and for the benefit of the 70 × 2020 state initiative, certain screenings such as stool test need to be promoted and recommended by family practitioners, and certain subgroups of the population such as smokers need to be targeted and educated.
