Abstract

Objectives: Socioeconomic status plays an important role in health care and disease prevention. This study aimed to examine the association between socioeconomic status, measured by education levels and household income, and gastric cancer screening. Methods: A total of 21,220 community-dwelling adults aged 40 to 69 years within a defined geographic area participated in a community health survey in 2009 and 2010. The survey was conducted using a structured questionnaire by trained investigators who visited the subjects' households directly. Logistic regression analysis was used to determine the relationship between self-reported participation in gastric cancer screening and socioeconomic variables (education and household income). Results: The gastric cancer screening rate was 52.1% for subjects in their forties, 63.7% for those in their fifties, and 67.3% for those in their sixties. In multivariate analysis, higher education and income levels were associated with higher rates of gastric cancer screening (high school vs. elementary school: odds ratio [OR] 1.41, 95 % confidence interval [CI] 1.26-1.58; highest income quartile vs. lowest income quartile: OR 1.62, 95% CI 1.44-1.84). The gradient between income and screening rate was more pronounced in the population aged 40 to 49 years than in the other age groups. Conclusions: This study demonstrates that lower socioeconomic status is associated with decreased participation in gastric cancer screening. Our findings suggest that the screening program should be focused on low-income and less-educated populations, especially among younger adults, to reduce health disparities.

이 연구에서는 위암검진 참여 현황을 파악하고, 수검률에 영향을 미치는 요인 중 사회경제상태 지표인 소득, 교육수준과 위암 수검률의 관련성을 알아보고자 하였다. 이 연구는 2009년과 2010년 전라남도 지역사회 건강조사 자료를 이용하였으며 40세부터 69세까지 21,220명을 대상으로 분석하였다. 사회경제상태와 위암 수검률과의 관련성은 로지스틱 회귀분석을 이용하여 분석하였다. 연령별 암 수검률은 40대 52.1%, 50대 63.7%, 60대 67.3%로 연령에 따라 증가하였다. 교육 수준이 높을수록 위암 수검률에 대한 교차비는 증가하였다(무학을 포함한 초등학교 졸업을 기준으로 중학교 졸업 OR=1.21; 95% CI=1.07-1.37, 고등학교 졸업 이상 OR=1.41; 95% CI=1.26-1.58). 또한 소득이 높을수록 위암 수검률에 대한 교차비도 증가하였다(2사분위 OR=1.14; 95% CI=1.02-1.28, 3사분위 OR=1.30; 95% CI=1.13-1.48, 4사분위 OR=1.62; 95% CI=1.44-1.84). 소득수준에 따른 위암 검진율은 연령대에 따라 다른 양상을 보였다. 이러한 차이는 40대에서 가장 높았다(40대 2사분위 OR=1.26; 95% CI=1.03-1.54, 3사분위 OR=1.49; 95% CI=1.20-1.86, 4사분위 OR=2.03; 95% CI=1.65-2.50, p for interaction=0.05). 낮은 사회경제상태는 낮은 위암 수검률과 관련이 있었으며, 특히 40대에서 사회경제상태에 따른 위암 수검률 차이가 크게 나타났다. 사회경제상태에 따른 위암 수검률 격차를 줄이기 위해서는 연령대별로 검진 형평성 달성을 위한 정책적, 환경적 지원이 요구될 것으로 보인다.
