To investigate the effects of public and private health insurance on self-rated health (SRH) status within the National Health Insurance (NHI) system based on socioeconomic status in South Korea. The data were obtained from 10 867 respondents of the Korea Health Panel (2008-2011). We used hierarchical panel logistic regression models to assess the SRH status. We also added the interaction terms of socioeconomic status and type of health insurance as moderators. Medical aid (MA) recipients were 2.10 times more likely to have a low SRH status than those who were covered only by the NHI, even though the healthcare utilization was higher. When the interaction terms were included, those not covered by the NHI and had completed elementary school or less were 16.59 times more likely to have a low SRH status than those covered by the NHI and had earned a college degree or higher. Expanding healthcare coverage to reduce the burden of non-payment and unmet use to improve the health status of MA beneficiaries should be considered. Particularly, the vulnerability of less-educated groups should be focused on.
为了探讨韩国国民健康保险（NHI）制度下基于社会经济地位的公共和私人医疗保险对自评健康（SRH）状况的影响。数据来自韩国健康小组（2008-2011 年）的 10867 名受访者。我们使用分层面板逻辑回归模型评估 SRH 状况。我们还添加了社会经济地位和医疗保险类型的交互项作为调节因素。与仅参加 NHI 的人相比，接受医疗援助（MA）的人出现低 SRH 状态的可能性高 2.10 倍，尽管他们的医疗利用率更高。当包含交互项时，那些未参加 NHI 且仅完成小学或以下学业的人出现低 SRH 状态的可能性比那些参加 NHI 且拥有大学学历或更高学历的人高 16.59 倍。应考虑扩大医疗保健覆盖范围，以减轻自费和未使用的负担，改善 MA 受益人的健康状况。特别是，应关注受教育程度较低群体的脆弱性。
