Interventions Promoting Colorectal Cancer Screening Among Latino Men: A Systematic Review.

INTRODUCTION

Colorectal cancer, the second leading cause of cancer death in the United States, is also among the most preventable cancers. However, Latino men are less likely than non-Latino men to engage in preventive screening. Compared with 60% of non-Latino white men and women, only 42% of Latino men are up to date with colorectal cancer screening guidelines, which may result in diagnosis at advanced disease stages and increased deaths. We evaluated the literature on colorectal cancer screening interventions among Latino men to characterize intervention components effective in increasing colorectal cancer screening.

METHODS

Two independent reviewers searched MEDLINE, CINAHL, and PsycINFO to identify articles on intervention studies that promote colorectal cancer screening among Latino men. Inclusion criteria were randomized controlled or comparative effectiveness trials, an outcome of any colorectal cancer screening test, published in English, US-based, results published from January 2004 through December 2016, Latino or Spanish-speaking male participants, and a minimum of one patient-level component. Two other reviewers independently assessed article quality and conducted data abstraction.

RESULTS

Forty-four studies met the inclusion criteria; only 7 studies with 20% or more Latinos and 39% or more men were included in the final analyses. The most common intervention strategies included one-on-one interactions with a patient navigator and reducing structural barriers (eg, providing fecal occult blood tests). Interventions using small media produced mixed results.

CONCLUSION

Although intervention studies focused on colorectal cancer screening among men of racial/ethnic minorities are scarce, our findings highlight promising strategies that were effective at increasing colorectal cancer screening among Latino men. Additional research in the area of Latino men's health is needed, especially to further develop and test theoretically grounded interventions that promote colorectal cancer screening with larger samples of men and across diverse geographic areas in the United States.
