Understanding labour exploitation as a social determinant of health in migrant populations – insights from the Danish population-based registers

Abstract Despite recent global events such as the COVID-19 pandemic and the Qatar world cup drawing attention to the significant loss of human lives of labour migrants in precarious working conditions, evidence on the comparative mortality of migrant workers remains sparse and inconsistent. Studying the comparative mortality of migrant workers with local workers is challenging for several reasons. Data on migrants’ employment conditions and health outcomes are often incomplete, and when available captured in separate databases. In addition, there is a need to disentangle the healthy migrant effect from the healthy worker effect, which presents challenges in the selection of reference populations and temporality when studying mortality of migrants. In view of such challenges, Denmark provides an ideal context to study labour migration and mortality. The Danish population-based registers offer linked longitudinal data on migrants’ employment history and mortality outcomes. Denmark’s migrant integration policy also has a history of weaving immigration and labour policies, and migrants in Denmark continue to be prone to labour exploitation in high-risk industries such as construction and agriculture. This presentation shall use Denmark as a case study to compare the mortality outcomes of migrant workers with Danish workers to better understand labour exploitation as a social determinant of health.
