Abstract

In the United States, the five-year survival rate of colorectal cancer for Latinos is lower than it is for White, non-Latinos. Differences in survival are due, in part, to Latinos being diagnosed at a later stage. An ethnic gap in the use of colorectal cancer screening contributes to the difference in survival. We developed, implemented, and evaluated a targeted colorectal cancer screening intervention to increase colorectal cancer screening uptake by sex, ethnicity, and geography. We measured actual colorectal cancer screening uptake in both arms as a method to determine completion rates. We used a randomized, community-based, participatory design to test the impact of social support (intervention) on completion of a provider-recommended, take-home fecal immunochemical test (FIT) kit screening test among average-risk, urban, and rural Pennsylvania Latino adults age 50 and older not currently adherent to national colorectal cancer screening guidelines (n ¼ 264). Participants in each arm attended a community-based educational program offered at eight sites. Among the 264 participants, 154 (58%) returned a completed usable FIT kit screening test. A higher return rate was observed among participants in the social support arm (66.0%) compared with the control (47.2%). Participants in the social support arm were statistically significant 2.67 times as likely to return a completed FIT kit. Of these, 27 (17.5%) had a positive FIT kit screening test result. The results of this study suggest that social support is an effective method to increase colorectal cancer screening rates among Latinos. Future studies should examine dissemination and implementation of community-based strategies among Latinos that include social support.
