While colorectal cancer (CRC) is common in Asian countries, screening for CRC is not. Moreover, CRC screening behaviors in Asian populations remain largely unknown. The present study aimed to investigate the stages of adopting CRC screening in Korea according to screening modality.
Data were obtained from the 2014 Korean National Cancer Screening Survey, a cross-sectional survey that utilized nationally representative random sampling to investigate cancer screening rates. A total of 2,066 participants aged 50-74 years were included in this study. Chi-square test and multinomial logistic regressionwere applied to determine stages of adoption for fecal occult blood test (FOBT) and colonoscopy and factors associated with each stage.
Of 1,593 participants included in an analysis of stage of adoption for FOBT, 36% were in action/maintenance stages, while 18%, 40%, and 6% were in precontemplation, contemplation, and relapse/relapse risk stages, respectively. Of 1,371 subjects included in an analysis of stage of adoption for colonoscopy, 48% were in action/maintenance stages, with 21% in precontemplation, 21% in contemplation, and 11% in relapse/relapse risk stages. Multinomial logistic regression highlighted sex, household income, place of residency, family history of cancer, having private cancer insurance, smoking status, alcohol use, and regular exercise as being associated with stages of adoption for FOBT and colonoscopy.
This study outlines the distributions of stages of adoption for CRC screening by screening modality. Interventions to improve screening rates should be tailored to individuals in particular stages of adoption for CRC screening by modality.
虽然结直肠癌（CRC）在亚洲国家很常见，但 CRC 的筛查却并非如此。此外，亚洲人群的 CRC 筛查行为在很大程度上仍不清楚。本研究旨在根据筛查方式调查韩国 CRC 筛查采用的阶段。
数据来自 2014 年韩国国家癌症筛查调查，这是一项横断面调查，利用全国代表性的随机抽样来调查癌症筛查率。共有 2066 名年龄在 50-74 岁的参与者纳入本研究。采用卡方检验和多项逻辑回归分析来确定粪便潜血试验（FOBT）和结肠镜检查的采用阶段以及与每个阶段相关的因素。
在 FOBT 采用阶段分析中，1593 名参与者中有 36%处于行动/维持阶段，而分别有 18%、40%和 6%处于未考虑、考虑和复发/复发风险阶段。在结肠镜检查采用阶段分析中，1371 名参与者中有 48%处于行动/维持阶段，分别有 21%、21%和 11%处于未考虑、考虑和复发/复发风险阶段。多项逻辑回归强调了性别、家庭收入、居住地点、癌症家族史、拥有私人癌症保险、吸烟状况、饮酒和规律运动与 FOBT 和结肠镜检查的采用阶段相关。
本研究概述了不同筛查方式下 CRC 筛查采用阶段的分布。提高筛查率的干预措施应根据特定筛查方式的采用阶段来针对个人进行定制。
