华裔和韩裔美国人的结直肠癌（CRC）筛查率低于其他种族/族裔群体，这可能是由于CRC知识水平低和误解程度高。本研究探讨了知识在这些群体中CRC筛查中的作用。从华盛顿大都会区招募50岁以上的中国（N=59）和韩国（N=61）美国人。他们完成了一项详细的调查，并参加了焦点小组，讨论他们对CRC和CRC筛查的知识。17名医生，社区领导人和患者导航员参加了关键的线人访谈。使用混合方法对数据进行定量和定性分析。参与者缺乏关于CRC和CRC筛查的知识。超过一半的人不知道筛查从50岁开始，有几种类型的测试可用。超过30%的人认为，如果没有症状或无法预防CRC，就没有必要进行CRC筛查。焦点小组的调查结果表明，对CRC的理解是有限的语言和文化相关的健康信息来源不足。例如，许多参与者认为CRC是一种主要由不健康饮食引起的西方疾病。这导致低估了他们对CRC的易感性。知识与自我报告的筛查呈正相关。知识得分较高的参与者更有可能报告曾经进行过结肠镜检查，并对进行CRC筛查的能力充满信心。混合方法分析为CRC知识及其对筛查的影响提供了多方面的观点。研究结果可以帮助提供干预措施，以增加中国和韩国美国人的CRC筛查。
Chinese and Korean Americans have lower colorectal cancer (CRC) screening rates than other racial/ethnic groups, which may be explained by a low level of CRC knowledge and a high level of misconceptions. This study explores the role of knowledge in CRC screening among these groups. Chinese (N=59) and Korean (N=61) Americans older than 50 were recruited from the Washington D.C. Metropolitan area. They completed a detailed survey and participated in focus groups to discuss their knowledge on CRC and CRC screening. Seventeen physicians, community leaders, and patient navigators participated in key informant interviews. Using a mixed methods approach, data were analyzed quantitatively and qualitatively. Participants lacked knowledge about CRC and CRC screening. More than half did not know that screening begins at age 50 and there are several types of tests available. More than 30% thought CRC screening was not necessary if there were no symptoms or there was nothing they could do to prevent CRC. Focus group findings suggested understanding about CRC was limited by an inadequate source of linguistically and culturally relevant health information. For example, many participants considered CRC a western condition mainly caused by unhealthy diet. This led to under-estimations about their susceptibility to CRC. Knowledge was positively associated with self-reported screening. Participants who had higher knowledge scores were more likely to report ever having had a colonoscopy and confidence in ability to have CRC screening. Mixed-methods analysis provides multi-faceted perspectives on CRC knowledge and its influence on screening. Study findings can help inform interventions to increase CRC screening among Chinese and Korean Americans.
