Summary: The GuLF STUDY (Gulf Long-term Follow-up Study) is a health study for individuals who helped with the oil spill cleanup, took training, signed up to work, or were sent to the Gulf to help in some way after the Deepwater Horizon disaster. The GuLF STUDY is designed to find answers to the questions that matter to oil spill clean-up workers and affected communities. Between 2011 and 2013, about 33,000 participants joined the study by completing a telephone interview, making it the largest study ever conducted on the health effects of an oil spill. Participants include adults ages 21 and over 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. More than 11,000 of the participants from the five Gulf coast states completed home examinations, which included additional questionnaires and collection of biological and environmental samples.
