Colorectal cancer, the second leading cause of mortality in the USA, can be prevented with colorectal cancer screening. However, many people who should receive the screening do not get screened. To learn more, this study estimated the prevalence of up-to-date colorectal cancer (CRC) screening and examined the relationship between CRC knowledge and screening compliance among Asian Americans living in the Baltimore-Washington Metropolitan area. The study included a cross-sectional sample of 274 Chinese, Korean, and Vietnamese Americans aged 50-75 years old. Participants completed a questionnaire regarding CRC knowledge in either their preferred native language or in English, and data were collected in person. The percentage of total participants with up-to-date overall CRC screening was 52.9%. Up-to-date fecal occult blood test (FOBT) screening was 15.0% and colonoscopy was 50.7%. The average CRC knowledge score was 6.10 out of 9 (SD = 2.91). Those with high education, high English proficiency, married, health insurance, and good physical health ratings had higher CRC knowledge. In multivariate analysis, CRC knowledge was significantly correlated with increasing up-to-date colonoscopy (aOR = 2.74, 1.13-6.64). Having health insurance (aOR = 4.40, 2.33-8.32) was another predictor of up-to-date colonoscopy. These findings suggest that CRC knowledge is a strong predictor of CRC screening behavior in Asian American populations. Lack of CRC screening knowledge still remains an important barrier to screening, and increased public awareness is necessary to achieve greater screening compliance.
结直肠癌是美国第二大死亡原因，可以通过结直肠癌筛查来预防。然而，许多应该接受筛查的人并未进行筛查。为了了解更多信息，本研究估计了居住在巴尔的摩-华盛顿大都市区的亚裔美国人最新结直肠癌（CRC）筛查的流行率，并检查了 CRC 知识与筛查合规性之间的关系。该研究包括 274 名年龄在 50-75 岁的华裔、韩裔和越裔美国人的横断面样本。参与者用他们首选的母语或英语完成了一份关于 CRC 知识的问卷，并亲自收集数据。总参与者中有 52.9%接受了最新的整体 CRC 筛查。最新粪便潜血试验（FOBT）筛查率为 15.0%，结肠镜检查率为 50.7%。CRC 知识平均得分为 9 分中的 6.10 分（SD=2.91）。受教育程度高、英语水平高、已婚、有医疗保险和身体健康评分好的人 CRC 知识更高。在多变量分析中，CRC 知识与增加最新结肠镜检查呈显著相关（aOR=2.74，1.13-6.64）。有医疗保险（aOR=4.40，2.33-8.32）也是最新结肠镜检查的另一个预测因素。这些发现表明，CRC 知识是亚裔美国人 CRC 筛查行为的有力预测因素。CRC 筛查知识的缺乏仍然是筛查的一个重要障碍，需要提高公众意识以实现更高的筛查依从性。
