Gulf Long-term Follow-up Study (GuLFSTUDY)
The GuLFSTUDY Program aims to study the health of workers and volunteers who responded to the 2010 Deepwater Horizon oil spill in the Gulf of Mexico in the United States of America (USA). Between 2011 and 2013, the study enrolled and assessed around 33,000 adults aged 21 years and over from across the USA who helped with the oil spill clean up, took training, signed up to work, or were sent to the Gulf to help in some way. First follow-up interviews were conducted between 2013 and 2016, and a subset of participants completed additional mental health-focused assessments 6, 12, and 24 months later. A subset of participants also completed clinical examinations between 2014 and 2016. Second follow-up interviews were conducted from 2017 to 2021. Participants are also followed for mortality and cancer incidence using publicly available data.
