Unmet healthcare needs index is widely used as an indicator to measure the performance of health care system and inequality of healthcare. It needs to be paid more attention since recent studies report that unmet healthcare needs have a negative effect on health outcome. There are little knowledge and research on how unmet healthcare needs affect health although it is essential for the policy effectiveness. This study explored the relationship between unmet healthcare needs and subjective health status by analyzing the interaction effect of income level, which is an important factor both for healthcare utilization and health. We estimated the modification effect of the income level to the health effects of unmet healthcare needs. The generalized estimation equation (GEE) was applied include 1-year time-lagged effect. A 6-year(from 2009 to 2014) data of Korea Health Panel was analyzed. It has confirmed that unhealthy influence of unmet healthcare needs is more effective in the low-income group than the high-income group. The additive interaction effect size of EQ-VAS was 2.29, and 0.48 in self-rated health. Interaction effects were prominent in the unmet needs experiences due to user`s resource shortage. The trend of unhealthy effects of both income and unmet healthcare needs was increasing, but the slope which means the additive interaction effect was gradually decreasing. The presence of additional interactions means that there are other complex influence factors that are not accounted for by income alone. To address unmet healthcare needs aimed at improving health, other factors besides financial issues for healthcare use should be considered, and efforts should be made to identify pathways and mechanisms between experiencing unmet healthcare needs and health.
