Introduction Several organizations now recommend average risk individuals begin colorectal cancer (CRC) screening at age 45 instead of 50 years. We present contemporary estimates of CRC screening in newly eligible adults ages 45-49 years between 2019-2021. Methods Nationally representative prevalence estimates and population number screened were estimated from the National Health Interview Survey. A logistic regression model assessed CRC screening prevalence differences by survey year and sociodemographic characteristics. Results In 2021, 19.7%, or fewer than 4 million of the eligible 19 million adults ages 45-49 years, were up-to-date for CRC screening. Screening was lowest in uninsured (7.6%), less than a high school diploma (15.4%), and Asian (13.1%) persons. Additionally, FOBT/FIT testing was under-utilized with only 2.4% (< 460 thousand persons) reporting being screened up-to-date with this modality in 2021. Discussion CRC screening in eligible young adults remains low. Concerted efforts to improve screening are warranted, particularly in underserved populations.

2019-2021 年美国 45-49 岁成年人结直肠癌筛查测试暴露模式

简介 现在，一些组织建议​​平均风险人群在 45 岁而不是 50 岁时开始结直肠癌 (CRC) 筛查。我们提出了 2019 年至 2021 年间对 45-49 岁新符合条件的成年人进行 CRC 筛查的当代估计。方法 全国代表性的患病率估计值和筛查的人口数量是根据全国健康访谈调查估计的。逻辑回归模型根据调查年份和社会人口学特征评估了 CRC 筛查患病率差异。结果 到 2021 年，1900 万年龄在 45-49 岁之间的合格成年人中，有 19.7%（即不到 400 万）接受了最新的 CRC 筛查。没有保险（7.6%）、高中文凭以下（15.4%）和亚洲人（13.1%）的筛查率最低。此外，FOBT/FIT 检测未得到充分利用，只有 2.4%（<46 万人）报告称在 2021 年使用这种方式进行了最新筛查。讨论 符合条件的年轻人中的 CRC 筛查率仍然很低。有必要共同努力改善筛查，特别是在服务不足的人群中。
