Systematic Review
To perform a meta-analysis of the currently available studies to further explore the effectiveness of peer support in promoting healthcare in ethnic minorities and alleviating disparities in colorectal cancer moribidty and mortality.
Thirteen studies comprising 8090 participants met the eligibility criteria. Peer support intervention can increase colorectal cancer screening implementation and raise awareness and intention to undergo the screening in ethnic minorities more significantly than fecal occult blood test outreach, print, and usual care. Subgroup analysis showed that peer support intervention achieved great results in Asian Americans and intervention of peer counseling.
Peer support can significantly improve the awareness about and the intention for receiving colorectal cancer screening in ethnic minorities and is an ideal choice for promoting the screening among ethnic minorities, particularly in a diverse community. Peer support intervention is recommended to promote the implementation of screening in Asian Americans. Peer counseling is worth promoting; however, church-based peer counseling programs require enhanced management to maintain their fidelity.
