The risk of eating disorders following the August 4th, 2020 explosion in Beirut and its relationship with trauma exposure and PTSD symptoms.
Asian Journal of Psychiatry 2023 August 24
INTRODUCTION: To date, no study has demonstrated the link between the diagnosis of provisional PTSD and ED in people exposed to the explosion of August 4th, 2020.
METHODS: Online participants were classified into 4 categories according to the degree of exposure to the explosion (unexposed, slightly exposed, moderately exposed, and severely exposed). The screening for ED was done using the standardized SCOFF questionnaire and the screening for provisional PTSD using the standardized IES-R questionnaire.
RESULTS: Our sample included 703 participants. In the bivariate analysis, there was a trend for an association between degree of exposure to the explosion and the risk of development of an ED (p = 0.055). The independent variables included in the multivariate analysis that were statistically associated with a risk of developing eating disorders are secondary school as the highest level of education (p = 0.029; OR = 2.15) and the risk of PTSD (p = 0.041; OR = 2.05) according to IES-R, specifically hyperarousal (p = 0.028; OR = 1.07) as a symptom cluster. Provisional PTSD played a mediating role, creating a partial and indirect relationship between the degree of exposure to the explosion and the risk of developing ED with a β coefficient of 0.075 (p < 0.001) CONCLUSION: The risk of PTSD according to IES-R was found to be a determinant of a higher risk of developing ED among participants exposed to the explosion in addition to mediating between the effect of exposure severity and the risk of ED. It is essential to fully assess and manage PTSD symptoms and ED patients exposed to such a psychological trauma.
