Outline of Final Research Achievements

In order to develop the effective policies to reduce the health problems of precarious employees, researchers need to build evidence about the health effects of precarious employment. First, we examined whether precarious employment increased the risk of health problems over four years in a nationally representative cohort of Japanese middle-aged people. Results suggest that precarious employment is associated with double the risk of incidence of mood or anxiety disorders among Japanese men. Second, we quantified the contribution of precarious employment to changes in health inequalities between 1986 and 2007 in a national sample of Japanese adults. Results suggest that an increase in precarious employment did not contribute to health inequalities.
