Colorectal cancer (CRC) is the second leading cause of cancer death in the United States of cancers that affect both men and women. Despite strong evidence that screening for CRC reduces incidence and mortality, CRC screening prevalence is below the national target. This report describes current CRC screening prevalence by age, various demographic factors, and state.
Data from the 2018 Behavioral Risk Factor Surveillance System survey were analyzed to estimate the percentages of adults aged 50-75 years who reported CRC screening consistent with the United States Preventive Services Task Force recommendation.
In 2018, 68.8% of adults were up to date with CRC screening. The percentage up to date was 79.2% among respondents aged 65-75 years and 63.3% among those aged 50-64 years. CRC screening prevalence was lowest among persons aged 50-54 years (50.0%) and increased with age. Among respondents aged 50-64 years, CRC screening prevalence was lowest among persons without health insurance (32.6%) and highest among those with reported annual household income of ≥$75,000 (70.8%). Among respondents aged 65-75 years, CRC screening prevalence was lowest among those without a regular health care provider (45.6%), and highest among those with reported annual household income ≥$75,000 (87.1%). Among states, CRC screening prevalence was highest in Massachusetts (76.5%) and lowest in Wyoming (57.8%).
CRC screening prevalence is lower among adults aged 50-64 years, although most reported having a health care provider and health insurance. Concerted efforts are needed to inform persons aged <50 years about the benefit of screening so that screening can start at age 50 years.
结直肠癌（CRC）是美国男女共患的癌症死亡的第二大原因。尽管有强有力的证据表明 CRC 筛查可降低发病率和死亡率，但 CRC 筛查的普及率低于国家目标。本报告描述了按年龄、各种人口统计学因素和州划分的当前 CRC 筛查普及率。
对 2018 年行为风险因素监测系统调查的数据进行了分析，以估计报告符合美国预防服务工作组建议的 50-75 岁成年人中 CRC 筛查的百分比。
2018 年，有 68.8%的成年人接受了 CRC 筛查。65-75 岁的受访者中有 79.2%接受了筛查，而 50-64 岁的受访者中有 63.3%接受了筛查。CRC 筛查的普及率在 50-54 岁人群中最低（50.0%），并随年龄增长而增加。在 50-64 岁的受访者中，无健康保险的人 CRC 筛查的普及率最低（32.6%），而报告年收入≥75000 美元的人 CRC 筛查的普及率最高（70.8%）。在 65-75 岁的受访者中，无常规医疗保健提供者的人 CRC 筛查的普及率最低（45.6%），而报告年收入≥75000 美元的人 CRC 筛查的普及率最高（87.1%）。在各州中，马萨诸塞州的 CRC 筛查普及率最高（76.5%），怀俄明州最低（57.8%）。
尽管大多数人报告有医疗服务提供者和健康保险，但 50-64 岁的成年人 CRC 筛查的普及率较低。需要做出协调一致的努力，使年龄<50 岁的人了解筛查的益处，以便从 50 岁开始进行筛查。
