OBJECTIVES To examine the income gaps associated with self-rated poor health at the district level in Korea and to identify the geographical correlations between self-rated poor health, life expectancy, and the associated income gaps.
METHODS
We analyzed data for 1,578,189 participants from the Community Health Survey of Korea collected between 2008 and 2014. The age-standardized prevalence of self-rated poor health and the associated income gaps were calculated. Previously released data on life expectancy and the associated income gaps were also used. We performed correlation and regression analyses for self-rated poor health, life expectancy, and associated income gaps.
RESULTS
Across 245 districts, the median prevalence of self-rated poor health was 15.7% (95% confidence interval [CI], 14.6 to 16.8%), with interquartile range (IQR) of 3.1 percentage points (%p). The median interquintile gaps in the prevalence of self-rated poor health was 11.1%p (95% CI, 8.1 to 14.5%p), with IQR of 3.6%p. Pro-rich inequalities in self-rated health were observed across all 245 districts of Korea. The correlation coefficients for the association between self-rated poor health and the associated income gaps, self-rated poor health and life expectancy, and income gaps associated with self-rated poor health and life expectancy were 0.59, 0.78 and 0.55 respectively.
CONCLUSIONS
Income gaps associated with self-rated poor health were evident across all districts in Korea. The magnitude of income gaps associated with self-rated poor health was larger in the districts with greater prevalence of self-rated poor health. A strong correlation between self-rated poor health and life expectancy was also observed.
Summary
Korean summary
본 연구에서는 우리나라 245개 시군구의 자가평가 불건강 유병률의 소득수준 간 격차 크기를 규명하고, 시군구 단위 자가평가 불건강 유병률과 그것의 소득수준 간 격차, 기대수명 및 기대수명의 소득수준 간 격차의 상관성에 대하여 분석하였다. 연구 결과, 우리나라 245개 모든 시군구에서 자가평가 불건강 유병률에서의 저소득층에 불리한 불평등이 존재하였다. 또한, 자가평가 불건강 유병률과 그것의 소득수준 간 격차, 기대수명 그리고 자가평가 불건강 유병률의 소득수준 간 격차와 기대수명의 소득수준 간 격차는 높은 상관성이 나타났다. 이 연구는 지방정부 차원에서 건강 형평성 현황에 관한 유의미한 정보를 제공하여 지역별 보건정책 수립의 근거로 활용할 수 있다는데 의의를 찾을 수 있다.
