目的：调查韩国不同收入群体癌症发病率和死亡率的不平等。研究设计：在回顾了2001年韩国国家癌症登记处的数据，以及国民健康保险和国民医疗援助的数据后，将49277例癌症患者分为六个收入群体。主要癌症的发病率和3年死亡率分别计算，并作为总数计算。方法：计算不平等斜率指数和不平等相对指数两个综合指数，分析肿瘤发病率的相对差异。以1类为参考，采用Cox回归模型对年龄进行调整，计算主要癌症的3年死亡率比。结果：最低收入组男性和女性患癌的相对危险度（总危险度）分别是最高收入组的1.65倍和1.43倍。就癌症死亡率而言，所有其他收入群体的3年死亡率都明显高于最高收入群体的配偶和女性。结论：本研究确定了韩国不同收入群体在癌症发病率和3年死亡率方面的不平等，其中大多数对低收入群体不利。建议低收入群体应在癌症筛查和住院医疗服务方面获得财政援助。(C) 2007年，皇家公共卫生研究所。Elsevier Ltd.出版。版权所有。
Objective: To investigate inequalities in cancer incidence and mortality across income groups in South Korea.Study design: After reviewing 2001 data from the Korean National Cancer Registry, and National Health Insurance and National Medical Aid data, 49,277 cancer cases were classified into six income groups. The incidence and 3-year mortality rates of major cancers were calculated separately and as a total.Methods: Two composite indices (slope index of inequality and relative index of inequality) were calculated to analyse the relative differences in cancer incidence. The 3-year mortality rate ratios for major cancers were calculated, with Class 1 as the reference, using a Cox regression model to adjust for age.Results: The relative risk of cancer incidence (total) in the lowest income group was 1.65 and 1.43 times higher than that in the highest income group for mates and females, respectively. For cancer mortality, all other income groups showed significantly higher 3-year mortality rate ratios than the highest income group for mates and females.Conclusions: This study identified inequalities in cancer incidence and 3-year mortality across income groups in South Korea, most of which were unfavourable to lower income groups. It is suggested that Lower income groups should receive financial assistance for cancer screening and inpatient medical services. (C) 2007 The Royal Institute of Public Health.
