Estimated based on the population size [1], the 12-month prevalence [2], and the treatment rate of 27.1% for major depressive disorder from the World Mental Health Japan Survey 2002–2003⁷^–⁹; the lost days, the reduced productivity days, and the impairment rates of 20% from the previous cost-of-illness studies of depression²⁰^,²¹; the average labor force participation rates [3]; and the average wage per day [4].
