Participation in colorectal cancer screening among Chinese Americans.
BACKGROUND
Colorectal cancer (CRC) is the second leading cause of cancer deaths in the United States and the third most common malignant neoplasm worldwide. Chinese Americans are one of the ethnic minority groups who have the lowest rates of CRC screening. The purpose of this study was to describe CRC screening among less acculturated Chinese Americans and to identify factors associated with CRC screening.


METHODS
We performed a review of 383 patients' medical records at a large community health clinic in Seattle's metropolitan area between July 2003 and September 2004. Outcome measurements included receiving fecal occult blood testing (FOBT) in the last 12 months, sigmoidoscopy in the previous 5 years and/or colonoscopy in the past 10 years. Compliance with CRC screening was assessed by documentation in patients' medical records.


RESULTS
The overall use of CRC screening per guidelines was 40%. Only 72(19%) patients had their FOBT test in the last 12 months. Eighty one patients (21%) had colonoscopy in the last 10 years and eleven (3%) of the patients had sigmoidoscopy in the last 5 years. Chi-square analyses revealed no significant differences between users and non-users of FOBT, sigmoidoscopy, and colonoscopy in terms of age, gender, insurance status or language.


CONCLUSIONS
Participation in CRC screening among less acculturated Chinese Americans was lower than rates derived from previous self-reported surveys. Research of effective preventive programs promoting annual FOBT is vital to increasing the use of CRC screening among this population.
