“…The NHID data have been reported to be comparable to data from Statistics Korea for calculating mortality at the national, provincial, and district levels [5]. Using the NHID data, inequalities in life expectancy by income have been explored in prior Korean studies [2,3,6].…”

We calculated life expectancy and inequalities therein by income for the period of 2016-2018 across the 253 electoral constituencies of the 20th National Assembly election in Korea. Methods: We obtained population and death data between 2016 and 2018 from the National Health Information Database and constructed abridged life tables using standard life table procedures according to gender and income quintiles for the electoral constituencies of the 20th National Assembly election held in 2016. Results: Life expectancy across the 253 constituencies ranged from 80.51 years to 87.05 years, corresponding to a gap of 6.54 years. The life expectancy difference by income across the 253 constituencies ranged from 2.94 years to 10.67 years. In each province, the difference in life expectancy by income across electoral constituencies was generally greater than the inter-constituency differences. Constituencies in capital and metropolitan areas showed a higher life expectancy and a lower life expectancy difference by income than constituencies in rural areas. Conclusions: Pro-rich inequalities in life expectancy by income existed in every electoral constituency in Korea. Both intra-constituency and inter-constituency socioeconomic inequalities in health should be highlighted in future policy-making in the National Assembly.

“…Based on the result of YLD, the difference between life expectancy in Korea suggested from the study of Khang et al (2019) and HALE from this study is as follows [9]. We found an increase of 1.25 years from 11.15 years in 2008 to 12.40 years in 2016.…”

“…The gap in life expectancy by gender decreased from 6.55 years in 2008 to 6.10 years in 2016 [9]. The gap in life expectancy by income level also decreased from 6.9 years in 2008 to 6.59 years in 2016.…”

Background: This study aims to calculate the health-adjusted life years (HALE) by using years lived with disability from the national claims data and aims to identify the differences and inequalities in income level and region. Methods: The study was carried out on total population receiving health insurance and medical benefits. We calculated incidence-based years lived with disability (YLD) for 260 disease groups, and this was used as the number of healthy years lost to calculate HALE. We adopted the insurance premium to calculate the income as a proxy indicator. For the region classification, we chose 250 administrative districts to cover the whole country.Results: The primary outcome was HALE in the Korean population. The second outcome was the HALE’s gap in terms of income and region. HALE increased from 2008 to 2016. Results by gender suggest that HALE in males increases faster than in females. Results by income level show that HALE is higher in higher income level. In 2016, the gap in HALE between Q1 and Q2, the lower income group, was about 5.10 years. The gap in females by income level was smaller than that in males, which can be because males have greater inequality in terms of HALE by income level. Moreover, the gap in HALE by region was found to increase.Conclusions: Results suggest that there is an inequality in years of living with disability in terms of income level in Korea. Therefore, we need intensive management for the low-income group to promote HALE at the national level.
