Abstract PO-035: Factors associated with colorectal cancer screening in a peer-counseling intervention study in partnership with African American churches

Abstract

Abstract Background: Colorectal cancer (CRC) mortality is 47% higher in African American men and 34% higher in African American women compared to non-Hispanic white men and women. Methods: Nine African American churches in Los Angeles (LA) participated in a one-group pre/post-test pilot study to promote cancer screening (2015-2018). Each church identified 5 Community Health Advisors (CHAs) who received training to recruit study participants ages 50 to 75; assess participants’ adherence to cancer screening guidelines of the U.S. Preventive Services Task Force; and provide one-on-one counseling for participants who were not adherent. Participants completed telephone surveys 3 months after the intervention. The goal of this analysis was to understand CRC screening outcomes among 163 African American participants who were baseline non-adherent to CRC screening guidelines. We fit bivariate and multivariate mixed effects logistic regression models to assess correlates of (1) discussion of CRC screening with provider and (2) receipt of CRC screening during follow-up. Results: 49% of respondents reported that they discussed CRC screening with a provider during the follow-up period and 28% of respondents reported receipt of CRC screening. Respondents who reported that they were counseled by a CHA were more than twice as likely to discuss CRC screening with their provider as those who reported that they did not receive the intervention (54% versus 24%, p<0.005). Those who had a regular doctor, who had more than 3 health care visits in the past 3 months and who had a routine check-up in the past 12 months were also significantly more likely to discuss CRC screening with a provider (all p<.001). Females were almost twice as likely as males to receive CRC screening during the follow-up period than males (35% versus 18%, p<.02) and South LA residents were significantly less likely to receive CRC screening than participants outside of South LA (22% versus 38%, p<.02). Those who had a routine check-up in the past 12 months were also significantly more likely to report receipt of CRC testing during the follow-up period (all p<0.01). Those who had discussed CRC screening with a provider were significantly more likely to obtain CRC screening (p<.001). Knowledge of CRC screening guidelines was low overall but significantly higher among those who received CRC screening than among their counterparts who did not receive screening (p<.02). In multivariable analyses, receipt of CHA counseling (OR 3.77) was significantly associated with discussing CRC screening with a provider during follow-up but not with CRC screening. Residence in South LA (OR 0.38) was significantly associated with lack of CRC screening. Conclusions: Findings confirm the important role of health care providers and suggest that residence in South LA constitutes an additional barrier to CRC screening. Further research and additional resources are needed to address disparities in the uptake of CRC screening among African Americans, especially in South LA. Citation Format: Annette E.
