Effectiveness of a Controlled Trial to Promote Colorectal Cancer Screening in Vietnamese Americans.
American Journal of Public Health, 2010
We conducted a controlled trial of a public education and provider intervention to increase colorectal cancer (CRC) screening rates among Vietnamese Americans, who typically have lower rates than non-Hispanic Whites.Methods.
The public education intervention included a Vietnamese-language CRC screening media campaign, distribution of health educational material, and a hotline.
Vietnamese in Alameda and Santa Clara Counties, California, received the intervention from 2004 to 2006; Vietnamese in Harris County, Texas, were controls and received no intervention.
A quasi experimental study design with pre- and postintervention surveys of the same 533 participants was used to evaluate the combined intervention.Results.
The postintervention-to-preintervention odds ratio for having ever had a sigmoidoscopy or colonoscopy was 1.4 times greater in the intervention community than in the control community.
