Background/Significance: Rates of colorectal cancer (CRC) screening among Vietnamese Americans are lower than those of non-Hispanic whites.

Objective/purpose: To report the results of a community-based controlled intervention trial designed to increase CRC screening in Vietnamese Americans.

Methods: A longitudinal cohort quasi-experimental study design was used to evaluate the intervention. Using a listed sample of most common Vietnamese surnames, a random telephone pre-test survey enrolled 866 Vietnamese American participants and collected data on demographic, healthcare access, and knowledge, attitudes, and behaviors regarding CRC screening. A 2-year intervention targeting the Vietnamese American public (media campaign [newspaper articles, and print, radio and television ads]; booklets; and a screening hotline) and their healthcare providers (continuing medical education seminars, patient counseling materials, and provider newsletters and DVDs) was conducted in the intervention community of Alameda and Santa Clara Counties, California. The control community of Harris County, Texas received no intervention. Of the enrolled participants, 531 completed the post-test survey. The outcomes were 1) having a screening fecal occult blood test (FOBT) and 2) having a screening sigmoidoscopy or colonoscopy during the intervention period.

Results: At post-test participants residing in the intervention community had 1.7 the odds of having a screening FOBT during the intervention period and 1.7 the odds of having a screening sigmoidoscopy or colonoscopy during the intervention period than participants in the control community, even after controlling for differences between communities at pre-test.

Discussion/conclusion: The intervention was effective in increasing CRC screening tests, particularly sigmoidoscopy and colonoscopy, in the Vietnamese American community.

Learning Objectives:
1) By the end of the session, participants will be able to develop an effective colorectal cancer screening intervention. 2) By the end of the session, participants will be able to identify appropriate methods to evaluate cancer screening intervention trials.
