Abstract
OBJECTIVES
This study aimed to describe the regional avoidable mortality trends in Korea and examine the trends in avoidable mortality disparities between the Seoul Capital Area and non-Seoul-Capital areas, thereby exploring the underlying reasons for the trend changes.
METHODS Age-standardized mortality rates from avoidable causes between 2001-2020 were calculated by region. Regional disparities in avoidable mortality were quantified on both absolute and relative scales. Trends and disparities in avoidable mortality were analyzed using joinpoint regression models.
RESULTS Avoidable, treatable, and preventable mortalities in Korea decreased at different rates over time by region. The largest decreases were in the non-Seoul-Capital non-metropolitan area for avoidable and preventable mortality rates and the non-Seoul-
Capital metropolitan area for treatable mortality rates, despite the largest decline being in the Seoul Capital Area prior to around 2009. Absolute and relative regional disparities in avoidable and preventable mortalities generally decreased. Relative disparities in treatable mortality between areas widened. Regional disparities in all types of mortalities tended to improve after around 2009, especially among males. In females, disparities in avoidable, treatable, and preventable mortalities between areas improved less or even worsened.
CONCLUSIONS Trends and disparities in avoidable mortality across areas in Korea seem to have varied under the influence of diverse social changes. Enhancing health services to underserved areas and strengthening gender-oriented policies are needed to reduce regional disparities in avoidable mortality.

Summary
Korean summary
2001년부터 2020년까지 회피가능, 예방가능 사망률의 수도권과 비수도권 대도시, 비수도권 비대도시 지역 간 절대적, 상대적 격차는 대체로 감소했지만, 치료가능 사망률의 상대적 격차는 커졌다. 회피가능, 치료가능, 예방가능 사망률의 지역 간 격차는 2009년경 이후에 특히 남성에서 개선됐지만, 여성의 경우 덜 개선되거나 오히려 악화되기도 했다.
Key Message
Regional disparities in avoidable, treatable, and preventable mortalities tended to improve after around 2009, especially among males, but, in females, disparities in all types of mortalities between areas improved less or even worsened.
