Body Mass Index and Mortality in Blunt Trauma: The Right BMI can be Protective

There are limited studies examining the role of BMI on mortality in the trauma population. The aim of this study was to analyze whether the “obesity paradox” exists in non-elderly patients with blunt trauma. A retrospective study was performed on the Trauma Quality Improvement Program (TQIP) databas...

Description
Summary:There are limited studies examining the role of BMI on mortality in the trauma population. The aim of this study was to analyze whether the “obesity paradox” exists in non-elderly patients with blunt trauma. A retrospective study was performed on the Trauma Quality Improvement Program (TQIP) database for 2016. All non-elderly patients aged 18–64, with blunt traumatic injuries were identified. A generalized additive model (GAM) was built to assess the association of mortality and BMI adjusted for age, gender, race, and injury severity score (ISS). 28,475 patients (mean age = 42.5, SD = 14.3) were identified. 20,328 (71.4%) were male.
