Leinsalu M, Baburin A, Jasilionis D, et al. - This study was undertaken to investigate alterations and educational inequalities in suicide mortality among working-age men in the Baltic countries and Finland in relation to macroeconomic fluctuations. Census-linked longitudinal mortality data were applied to examine changes in overall suicide mortality and by educational level between the 2000–2003, 2004–2007, 2008–2011, and 2012–2015 periods among men aged 30–64 years. Researchers calculated age-standardized mortality rates, mortality rate ratios (Poisson regression), the relative index of inequality, and the slope index of inequality. It was shown that lower educated men had a smaller decline in suicide mortality than higher educated men during a period of rapid economic expansion in the Baltic countries, nevertheless, they were not more disadvantaged during the recession, possibly because of being less exposed to financial loss. Consequently, in suicide mortality, relative inequalities may increase during economic booms and decrease during recessions.
