Aims: Adverse social circumstances during one's life course have been related to an increased risk of mortality. This article extends the literature by focusing on adversity at each phase of, and cumulatively at midlife in the Swedish population.
Methods: Data on socioeconomic indicators from 1970, 1980 and 1990 were linked to death registrations from 2000 to 2009. Relative indices of inequalities were computed for socioeconomic indicators, in order to measure the cumulative impact of inequality on mortality.
Results: A significant cumulative effect of being in the worst-off socioeconomic groups was found. For men, almost all indicators had a significant independent impact on risk of death. Among women, significant independent impacts were found for education in 1990 and for socioeconomic index in the 2 census years of 1970 and 1980.
Conclusions: Being disadvantaged during a longer period in midlife has a significant negative impact on health. Policies targeted to reduce health inequality should focus on every stage of the midlife course.
