It is well known that educational attainment has a substantial effect on health. Using data obtained from Longitudinal Survey of Middle-aged and Older Adults, which was conducted by the Ministry of Health, Labour and Welfare in 2005-2014, we investigate the long-term impact of educational attainment on health among the middle-aged adults. This Survey tracks the changes in life and health conditions of the participants who were aged 50-59 years old in the first wave in 2005. In this study, we examined how educational attainment affects (1) changes in self-rated health and psychological distress measured by Kessler 6 score and (2) onsets of problems in activities of daily living and non-communicable diseases over twelve survey waves. We further investigate the mediating effects of income, job status, health behavior, marital status, and social activities on the impact of educational attainment on health outcomes.
