Deepwater Horizon Oil Spill Exposures and Long-term Self-rated Health Effects Among Parents in Coastal Louisiana.

PURPOSE: To assess whether exposure to the 2010 Deepwater Horizon oil spill (DHOS) was related to parents' self-rated health over time. DESIGN: 3 waves of panel data were drawn from the Gulf Coast Population Impact study (2014) and Resilient Children, Youth, and Communities study (2016, 2018). SETTING: Coastal Louisiana communities in high-impact DHOS areas. PARTICIPANTS: Respondents were parents or guardians aged 18 - 84, culled from a probability sample of households with a child aged 4 to 18 (N = 526) at the time of the 2010 DHOS. MEASURES: Self-rated health was measured at each wave. Self-reported physical exposure to the DHOS, economic exposure to the DHOS, and control variables were measured in 2014. ANALYSIS: We used econometric random effects regression for panel data to assess relationships between DHOS exposures and self-rated health over time, controlling for potentially confounding covariates. RESULTS: Both physical exposure (b = -0.39; P < 0.001) and economic exposure (b = -0.34; P < 0.001) to the DHOS had negative associations with self-rated health over the study period. Physical exposure had a larger effect size. CONCLUSION: Parents' physical contact with, and economic disruption from, the 2010 DHOS were tied to long-term diminished health.

Parental Education and Child Physical Health Following the BP Deepwater Horizon Oil Spill.

PURPOSE: To assess whether trajectories of children's physical health problems differ by parental college degree attainment in Louisiana areas highly impacted by the 2010 BP Deepwater Horizon oil spill (BP-DHOS). DESIGN: Three waves of panel data (2014, 2016, and 2018) from the Gulf Coast Population Impact / Resilient Children, Youth, and Communities studies. SETTING: BP-DHOS-impacted communities in coastal Louisiana. PARTICIPANTS: Parents of children aged 4-18 in a longitudinal probability sample (n = 392). MEASURES: Reported child physical health problems from the BP-DHOS, parental college degree attainment, and covariates. ANALYSIS: Linear growth curve models are used to assess initial levels of and the rate of change in child physical unknown. The current study uses 3 waves physical health problems by parental college degree attainment. Explanatory variables are measured at baseline and the outcome variable is measured at all 3 waves. RESULTS: Compared to children of parents without college degrees, children of college graduates had fewer initial health problems in 2014 (b = -.33; p = .02). Yet, this health advantage decreased over time, as indicated by their positive rate of change (b = .22; p = .01), such that the higher education health advantage was not statistically significant by 2018. CONCLUSION: Children of college graduates experienced a physical health advantage following the BP-DHOS, but this gap closed over time. The closure of the gap was due to the children of college graduates experiencing significant increases in reported health problems over the study period.
