This article describes the self-reported colorectal cancer (CRC) screening adherence rates of adults, aged 50 years and older, living in five nonurban Minnesota counties.
During the year 2000, 1693 eligible respondents, aged 50 years and older, from a randomly selected sample completed a survey assessing CRC screening adherence (approximately 86.3% response). The survey allowed differentiation between the four CRC screening modalities but did not differentiate between screening and diagnostic testing. Adjustment for nonresponse was performed using a version of Horvitz-Thompson weighting accounting for unknown eligibility.
24.5% of respondents had a fecal occult blood test within 1 year of the survey, 33.8% had flexible sigmoidoscopy within 5 years, 29.3% had a colonoscopy within 10 years, and 13.7% had a barium enema within the last 5 years. Overall, 55.3% of respondents reported testing by any modality; thus, 44.7% were not adherent to screening guidelines.
This study improves on previous attempts to characterize CRC screening adherence by assessing all four modalities of screening as recommended by current screening guidelines, by focusing on nonadherence, and by rigorously accounting for nonresponse. This study confirms that nearly half of the population remains unscreened by any method.
本文描述了居住在明尼苏达州五个非城市县的50岁及以上成年人自我报告的结直肠癌（CRC）筛查依从率。
在2000年，从随机抽取的样本中选取1693名50岁及以上的合格受访者完成了一项评估CRC筛查依从性的调查（回复率约为86.3%）。该调查能够区分四种CRC筛查方式，但未区分筛查和诊断测试。使用考虑未知合格情况的霍维茨 - 汤普森加权法的一个版本对无回复情况进行了调整。
24.5%的受访者在调查后1年内进行了粪便潜血试验，33.8%在5年内进行了乙状结肠镜检查，29.3%在10年内进行了结肠镜检查，13.7%在过去5年内进行了钡灌肠检查。总体而言，55.3%的受访者报告采用了任何一种方式进行检测；因此，44.7%的人未遵守筛查指南。
本研究在以往试图描述CRC筛查依从性的基础上有所改进，通过按照当前筛查指南的建议评估所有四种筛查方式、关注不依从情况以及严格考虑无回复情况。本研究证实，近一半的人群仍未接受任何方式的筛查。
