The association of health care access and utilization with self-perceived health in South Korea: the significance of age

Abstract

AbstractEven though South Korea’s universal health care system was established in 1989, many South Koreans continue to encounter obstacles in their attempts to access health care. Previous studies have not investigated the relationship between health care access and utilization and perceived health in the context of a universal health care system that implements a mandatory social health insurance policy. The objective of this study was to evaluate the influence of health care access and use of preventive health care services on self-rated health among young and middle-aged adults in Korea. The sample consisted of 1242 young adults aged 20–39 years and 2389 middle-aged adults aged 40–64 years who had participated in the cross-sectional 2015 Korea National Health and Nutrition Examination Survey. Using multiple logistic regression analysis, the association between health care access and use of preventive health care services and perceived poor health among young adults and middle-aged adults was assessed. The main finding was that a history of unmet health care requirements during the past 12 months was strongly associated with fair and poor self-rated health, especially among young adults. Additionally, middle-aged adults who had attended medical check-ups during the preceding 2 years reported poorer self-rated health. This study’s findings suggest that, despite South Korea’s universal public insurance system, there remains the need to improve access to health care services, especially among young adults. As a health improvement strategy, it is imperative that measures be taken to promote the availability of health care services when they are required and to solve any of the various individual accessibility problems, such as cost, particularly with young adults in mind.
