ObjectiveHurricane Maria and the subsequent large-scale relocation of Puerto Ricans to the United States mainland exemplify how severe weather events and population displacement affect the health of storm survivors. Our team has led several projects with this population, including Adelante Boricua, a longitudinal cohort study examining the interplay among severe weather events, displacement, resettlement, and mental health among relocated Hurricane Maria survivors. Drawing on 25 published studies over nearly a decade, this mini-review provides an overview of what our research team has learned from our work with this population.MethodWe distill several years of our team’s research and numerous scholarly articles into three major findings, considering the key policy and practice implications of each.ResultsMajor Adelante Boricua findings are presented, including evidence that for many displaced Puerto Ricans, posttraumatic stress represents a persistent, long-term challenge. We also found that, in terms of mental health, it is critical we consider both hurricane trauma and resettlement experiences. Additionally, many Puerto Ricans who relocated after Hurricane Maria reported having seriously considered leaving Puerto Rico long before the disaster struck.ConclusionGiven Puerto Rico’s unique status and history, we should exercise caution when generalizing findings from relocated Hurricane Maria survivors to other displaced populations within the United States and beyond. That said, much has been learned from the experiences of Hurricane Maria survivors who relocated, and we hope that health professionals, scientists, community leaders, and policymakers can leverage key insights from our research in preparation for future displacement crises.
