For decades, researchers have been puzzled by the finding that despite low socioeconomic status, fewer social mobility opportunities, and access barriers to health care, some migrant groups appear to experience lower mortality than the majority population of the respective host country (and possibly also of the country of origin). This phenomenon has been acknowledged as a paradox, and in turn, researchers attempted to explain this paradox through theoretical interpretations, innovative research designs, and methodological speculations. Specific focus on the salmon effect/bias and the convergence theory may help characterize the past and current tendencies in migrant health research to explain the paradox of healthy migrants: the first examines whether the paradox reveals a real effect or is a reflection of methodological error, and the second suggests that even if migrants indeed have a mortality advantage, it may soon disappear due to acculturation. These discussions should encompass mental health in addition to physical health. It is impossible to forecast the future trajectories of migration patterns and equally impossible to always accurately predict the physical and mental health outcomes migrants/refugees who cannot return to the country of origin in times of war, political conflict, and severe climate change. However, following individuals on their path to becoming acculturated to new societies will not only enrich our understanding of the relationship between migration and health but also contribute to the acculturation process by generating advocacy for inclusive health care.

Occupational health and safety concerns classically encompass conditions and hazards in workplaces which, with sufficient exposure, can lead to injury, distress, illness, or death. The ways in which work is organized and the arrangements under which people are employed have also been linked to worker health. Migrants are people who cross borders away from their usual place of residence, and about one in seven people worldwide is a migrant. Terms like “immigrant” and “emigrant” refer to the direction of that movement relative to the stance of the speaker. Any person who might be classified as a migrant and who works or seeks to work is an immigrant worker and may face challenges to safety, health, and well-being related to the work he or she does. The economic, legal, and social circumstances of migrant workers can place them into employment and working conditions that endanger their safety, health, or well-being. While action in support of migrant worker health must be based on systematic understanding of these individuals’ needs, full understanding the possible dangers to migrant worker health is limited by conceptual and practical challenges to public health surveillance and research about migrant workers. Furthermore, intervention in support of migrant worker health must balance tensions between high-risk and population-based approaches and need to address the broader, structural circumstances that pattern the health-related experiences of migrant workers. Considering the relationships between work and health that include but go beyond workplace hazards and occupational injury, and engaging with the ways in which structural influences act on health through work, are complex endeavors. Without more critically engaging with these issues, however, there is a risk of undermining the effectiveness of efforts to improve the lot of migrant workers by “othering” the workers or by failing to focus on what is causing the occupational safety and health concern in the first place—the characteristics of the work people do. Action in support of migrant workers should therefore aim to ameliorate structural factors that place migrants into disadvantageous conditions while working to improve conditions for all workers.
