Gastric cancer (GC) screening is a major challenge in countries where the disease is highly prevalent. This study was conducted to identify the factors associated with participation in GC screening and on-time rescreening among the average-risk population in Korea. The study population was derived from the National Cancer Screening Program database. The population for this study was 22 913 618 individuals aged ≥40 years who had been invited to participate in a GC screening program from 2005 to 2006. We determined whether these individuals had attended the GC screening program and which method - an upper gastrointestinal series (UGIS) or endoscopy-they underwent. We followed the participants to determine whether they had a second GC screening after 2 years. The overall participation rate in the GC screening was 20.5%. More people underwent UGIS than endoscopy. Individuals who had been screened by endoscopy rather than UGIS were more likely to be younger, male, or those who were National Health Insurance (NHI) beneficiaries with a higher premium rate. Of those who underwent baseline screening, 59.4% participated in a rescreening program 2 years later. NHI beneficiaries with a higher premium rate were significantly more likely to be rescreened than medical aid recipients. The results from this study showed that the UGIS were more commonly used in organized GC screenings in Korea, and those who underwent UGIS were more likely to return for subsequent screening compared to those who underwent an endoscopy.
胃癌（GC）筛查在疾病高发的国家是一项重大挑战。本研究旨在确定与韩国一般风险人群参与 GC 筛查和按时复查相关的因素。研究人群来自国家癌症筛查计划数据库。本研究的人群为 2005 年至 2006 年期间被邀请参加 GC 筛查计划的≥40 岁的 22913618 名个体。我们确定了这些个体是否参加了 GC 筛查计划以及他们接受了哪种方法 - 上消化道系列（UGIS）或内窥镜检查。我们对参与者进行了随访，以确定他们是否在 2 年后进行了第二次 GC 筛查。GC 筛查的总体参与率为 20.5%。接受 UGIS 检查的人数多于接受内窥镜检查的人数。接受内窥镜检查而不是 UGIS 检查的个体更年轻、更男性化，或者是具有较高保费率的国民健康保险（NHI）受益人的可能性更大。在接受基线筛查的个体中，有 59.4%的人在 2 年后参加了复查计划。具有较高保费率的 NHI 受益人的复查率明显高于医疗救助受助人。本研究结果表明，在韩国，UGIS 更常用于有组织的 GC 筛查，并且与接受内窥镜检查的个体相比，接受 UGIS 检查的个体更有可能进行后续筛查。
