AbstractDespite the fact that obesity is a known risk factor for comorbidities and complications, there is evidence suggesting a survival advantage for patients classified by body mass index (BMI) as overweight or obese. Investigated in various clinical areas, this "Obesity Paradox" has yet to be explored in the burn patient population. We sought to clarify whether this paradigm exists in burn patients. Data collected on 519 adult patients admitted to an American Burn Association Verified Burn Center between 2009 and 2017 was utilized. Univariable and multivariable logistic regression were used to determine the association between in-hospital mortality and BMI classifications (underweight <18.5 kg/m2, normal 18.5 to 24.9 kg/m2, overweight 25-29.9 kg/m2, obesity class I 30 to 34.9 kg/m2, obesity class II 35 to 39.9 kg/m2, and extreme obesity >40 kg/m2). For every kg/m2 increase in BMI, the odds of death decreased, with an adjusted odds ratio of 0.856 (95% confidence interval [CI] 0.767 to 0.956). When adjusted for total BSA (TBSA), being obesity class I was associated with an adjusted odds ratio of mortality of 0.0166 (95% CI 0.000332 to 0.833). The adjusted odds ratio for mortality for underweight patients was 4.13 (95% CI 0.416 to 41.055). There was no statistically significant difference in odds of mortality between the normal and overweight BMI categories. In conclusion, the obesity paradox exists in burn care: further investigation is needed to elucidate what specific phenotypic aspects confer this benefit and how these can enhance the care of burn patients.© American Burn Association 2020.
