AANCART Healthy Community Research Project

Colorectal cancer (CRC) is a highly prevalent cancer affecting both Asian men and women. Deaths due to CRC are unnecessary because CRC screening has been proven to reduce mortality and is cost-effective. Asian Americans have significantly lower CRC screening rates than non-Hispanic whites. Little is known about how to increase CRC screening rates among Asian Americans.
 
Specifically, AANCART investigators have showed in an analysis from the 2001 California Health Interview Survey (CHIS) that Asian Americans age 50 and over had lower rates of ever having been screened by FOBT, sigmoidoscopy/colonoscopy, or either (38%, 42%, and 58%, respectively) than non-Hispanic whites (58%, 57%, and 75%). Screening rates were very low for Filipinos (39%, 37%, and 57%) and Koreans (23%, 38%, and 49%). Findings were similar for being up-to-date. In the 2005 CHIS rates of receipt of any CRC test ever remained lower among all Asians (62%), Filipinos (66%), and Koreans (33%) compared to non-Hispanic whites (78%).  From 2001 to 2005, receipt of CRC screening ever actually declined in prevalence among Koreans in California. Thus, our full research project proposes to use CBPR methods to conduct a cluster randomized controlled trial (RCT) to evaluate the effectiveness of bilingual/bicultural lay health educators in increasing CRC screening rates among Filipino, Hmong, and Korean. It is an innovative project in its aim to understand if and how one intervention with many standardized components and some targeted elements can work across different Asian American populations, thus advancing the AANCART research agenda, which to date has evaluated interventions with one Asian group at a time.
