cer Surveillance Research nds in Socioeconomic Disparities in Organized and B & P ortunistic Gastric Cancer Screening in Korea ( 2005 - 2009 )

wnloaded kground: A growth of consensus and increasing activities related to organized cancer screening prohas occurred in Korea since 1999. It is important to assess disparities in the fight against cancer, and it ial to identify particular groups that may be experiencing a high burden of cancer-related illness. thods: Data from 8,160 men and women ages >40 years from the 2005 to 2009 Korean National Cancer ing Survey were used to analyze the relationship between socioeconomic position and receiving upper intestinal series or upper endoscopy within the past 2 years. We used absolute and relative concentradexes, that is, summary measures of disparity based on both rate differences and rate ratios. ults: For organized screening, the education disparity declined, but the income disparity index ind, indicating that participation in organized screening was relatively more concentrated among the income groups. For opportunistic screening, income and education disparities increased due to the ing of socioeconomic differences. clusions: The results of this study suggested progress toward socioeconomic disparity-related goals in ized screening for gastric cancer. However, the income disparity trends in organized screening may e in a manner similar to those in opportunistic screening in the future because of the much faster rate anized screening uptake by those higher on the socioeconomic scale. act: This study addresses the routine monitoring of coverage of screening among different socioImp economic groups and could be used to inform polices to reduce disparity in coverage.
