Relationship of education, occupation, and income with mortality in a representative longitudinal study of South Korea.

To examine relationship of education, occupation, and income with mortality risk, the 1998 National Health and Nutrition Survey data were linked to data on mortality. Education, occupation, and income had independent effects on mortality risk after adjustment for the remaining two socioeconomic position indicators. Educational, occupational, and financial approaches would be equally important to reduce socioeconomic mortality inequalities in South Korea.
