Background: Climate change disproportionately harms people of color and low-income communities. Despite their unprecedented numbers, being constantly on the move, and suffering extreme social vulnerability, almost nothing is known about the impact of climate change on the health of refugees. This study uses state-of-the-art mixed methods to examine the differential susceptibility of climate-sensitive exposures and environmental exposures among refugees and their links to perceived health after resettlement.
Methods: Arabic-speaking refugees (N=67) from Iraq and Syria previously diagnosed with hypertension who resettled in California were recruited from a community center. Semi-structured interviews were conducted to explore participant's understanding of the impact of climate on health. Survey data were collected to inquire regarding participant's refugee journeys prior to resettlement in the US. Survey data on climate-related disasters was retrospectively geo-referenced through the Emergency Events Database (EM-DAT). Qualitative data was analyzed using inductive thematic analysis.
Results: All participants stayed in at least one temporary resettlement country during their migration journey and 12% has stayed in refugee camps. The most popular resettlement sites were Turkey (most disaster-prone in the region due to frequent floods and earthquakes) and Jordan (one of the most extreme water-scarce globally). Participants reported harsh weather conditions during their migratory journeys including extreme cold in Turkey and extreme heat in Jordan. Many participants noted their exposure to dust throughout their travels, and an inability to deal with harsh weather conditions due to financial insecurity. Participants did not link their diagnosis of hypertension to their experience of extreme weather and would only link it to their exposure to stress from war. Participants did note poorer mental health due to poor weather conditions and a challenge adjusting to the climate conditions in different countries. Few participants reported residing in a refugee camp and described it as ill-equipped for the challenges of climate hazards.
Conclusion: This study reveals the links between structural drivers of climate change and health inequities for refugee populations. Refugees are highly vulnerable to climate-sensitive exposures but remain not fully aware of the potential links between these exposures and health. Learnings from this study will inform clinical and public health interventions, and policies to close the climate gap without leaving this vulnerable population behind.
