Educational inequality in cause-specific mortality among immigrants and their descendants in Sweden

INTRODUCTION: Although immigrants in Western countries often face disadvantages and vulnerabilities such as lower socioeconomic status, they tend to exhibit weaker educational gradients in mortality compared to the native majority populations. However, it is unclear how these gradients vary across specific causes of death and whether they persist among second-generation immigrants. Therefore, this study aims to investigate educational inequalities in cause-specific mortality among first- and second-generation immigrants compared to the native ancestral population in Sweden. DATA & METHODS: Individual-level analysis was conducted on Swedish register data from 2004 to 2016, including men and women aged 25 to 64. Poisson regression was used to examine the association between the highest educational degree attained and mortality due to circulatory diseases, neoplasms, external causes, self-harm, drug and alcohol use. RESULTS: The findings indicated that first-generation immigrants exhibited significantly lower educational inequality in all causes of death compared to native ancestral Swedes. In contrast, second-generation immigrants showed similar degrees of educational inequality in all-cause mortality and mortality due to neoplasms when compared to ancestral Swedes. However, they displayed more pronounced educational inequalities in mortality from external causes, self-harm, and drug use. CONCLUSIONS: The results highlight that while first-generation immigrants experience lower educational inequality in the considered causes of death, second-generation immigrants show pronounced educational inequalities in avoidable causes of death. This study emphasizes the importance of considering heterogeneity in educational disparities in immigrant mortality and calls for policy interventions to address educational inequalities in second-generation immigrants. KEY MESSAGES: • When compared to the native majority population, first-generation immigrants in Sweden demonstrate lower educational inequality in mortality, regardless of the underlying cause. • Conversely, second-generation immigrants display larger educational inequalities, particularly for mortality caused by preventable factors.
