Trends in educational inequalities in all-course mortality and deaths of despair in Swedish youths 1990–2018

Bakground

Growing educational disparities in mortality due to suicide, drug overdose, or alcohol-related liver disease – or “deaths of despair” (DoD) – have received increased attention in research and public debate. However, no study has investigated educational differences in despair-related mortality outside of North America. Thus, the aim this study was to investigate changes in the association between academic achievement in compulsory school and subsequent all-cause mortality (ACM) and DoD between 1990 and 2018 in Swedish youths.

Data and methods

Register data on all students graduating from compulsory school in Sweden between 1990 and 2010 were used (N = 2 252 938). Students were followed for a maximum of 8 years using discrete time proportional hazard models. Academic achievement was measured by grades at the end of compulsory school.

Results

ACM declined for medium/high achieving but not for low-achieving youths, while DoD increased slightly for medium/high achieving and markedly for low-achieving youths, resulting in growing achievement-related disparities in both types of mortality. The trends were primarily driven by native-born youth and girls.

Conclusions

The trends in Swedish youths resemble the trends in the American working-age population, but partly contrasts with corresponding trends in other European countries. Future research should investigate if the underlying causes that have been emphasized in the American context – socio-economic transformations and a greater supply of drugs – have also contributed to the Swedish trends.
