A Longitudinal Study of the Mental and Behavioral Health Effects Expressed in Lower Alabama Areas Affected by the Deepwater Horizon Oil Spill

Abstract

On April 20th, 2010, the Deepwater Horizon oil spill occurred in the Gulf of Mexico. This spill affected approximately 181 miles of Gulf Coast shoreline and impacted the livelihood of residents within Lower Alabama. Previous studies have shown increased behavioral health symptoms following high magnitude natural disasters. Symptom expression typically adheres to one of several trajectories: recovery, evidenced by gradual declines in symptoms over time, or delayed disruptions in functioning, evidenced by gradual increases in symptoms over time. However, very few existing studies have investigated the long term behavioral health effects of a large-scale technological disaster. Surveillance of mental and behavioral health symptoms over time can inform needed resiliency-restoring and recovery-related service provision resources. Using health surveillance methodology, plots were developed to depict the trajectory of behavioral health symptoms expressed by service-seeking Alabama Gulf Coast residents (n = 3,731 people) within impacted areas of Mobile and Baldwin counties. The presented data represents information gathered from disaster- deployed mental health service providers (e.g., number of patients treated and their behavioral health symptoms) in order to monitor fluctuations in behavioral health indicators across the recovery period. Six distinct time points were included in the analyses (6, 12, 18, 24, 30, and 36 months post-spill) Results demonstrate a period of recovery between 6 months and 18 months post-spill as evidenced by a gradual decline in behavioral health symptoms. However, beginning around 18 months post-spill and continuing through Year 3, delayed disruptions in functioning were evidenced by gradually increasing reports of behavioral health symptoms over time. Plots of symptom type and frequency will be presented as these demonstrate the need for programs such as the Gulf Region Health Outreach Program (GRHOP).Overall, the current study offers insight into the pattern of behavioral health responses experienced by Coastal Alabama residents over the three year period following the Deepwater Horizon oil spill. Results suggest that behavioral health symptoms in need of treatment still persist, with a trend of increasing symptoms present over the past year and a half. Several factors may be impacting continued symptom expression including ongoing litigation related to the oil spill, a lack of behavioral health care capacity within the Gulf Coast region, and the large percentage of individuals within the region who are experiencing on-going poverty and a lack of access to affordable health care.

“…22 Additional studies conducted across the Gulf states have concurred with these findings of mental health concerns and symptoms following the Gulf oil spill. [23][24][25][26][27][28][29][30][31] Importantly, unique to technological disasters is the prolonged recovery due to chronic stressors associated with the recovery process. 32 As individuals in impacted communities remain "stuck" in various stages of recovery, the health of the community at large is impacted.…”
