Résumé
Although many studies have demonstrated that obesity is correlated with an increased risk of chronic disease, some have reported a paradox by which those in the higher weight categories actually recover better during hospitalization. This study was designed to determine whether this obesity paradox is also reflected in the recovery of patients with traumatic brain injury (TBI) undergoing care in a rehabilitation hospital. To investigate the association between body mass index (BMI) and the functional progress of patients with TBI, admitted to a rehabilitation hospital. Retrospective cohort study. The study included all patients admitted to the brain injury unit of a rehabilitation hospital over a 6-year period. The data used for this study included patient height and weight (measured on admission) and functional independence measurements (scored on admission and discharge). Functional independence measure (FIM) change per day, BMI category. For the 444 patients admitted, the overall FIM efficiency did not differ significantly by BMI (P = .93). After adjusting for age and gender, overweight and obese patients had the lowest FIM efficiency (1.04 for both groups), followed by the underweight and normal weight groups (1.11 and 1.26, respectively). This study demonstrated that higher BMI was not significantly correlated with the rate of functional recovery among patients admitted to a rehabilitation hospital for TBI. III.

BACKGROUND
Although many studies have demonstrated that obesity is correlated with an increased risk of chronic disease, some have reported a paradox by which those in the higher weight categories actually recover better during hospitalization. This study was designed to determine whether this obesity paradox is also reflected in the recovery of patients with traumatic brain injury (TBI) undergoing care in a rehabilitation hospital.
OBJECTIVE
To investigate the association between body mass index (BMI) and the functional progress of patients with TBI, admitted to a rehabilitation hospital.
DESIGN
Retrospective cohort study.
METHODS
The study included all patients admitted to the brain injury unit of a rehabilitation hospital over a 6-year period. The data used for this study included patient height and weight (measured on admission) and functional independence measurements (scored on admission and discharge).
MAIN OUTCOME MEASURES
Functional independence measure (FIM) change per day, BMI category.
RESULTS
For the 444 patients admitted, the overall FIM efficiency did not differ significantly by BMI (P = .93). After adjusting for age and gender, overweight and obese patients had the lowest FIM efficiency (1.04 for both groups), followed by the underweight and normal weight groups (1.11 and 1.26, respectively).
CONCLUSION
This study demonstrated that higher BMI was not significantly correlated with the rate of functional recovery among patients admitted to a rehabilitation hospital for TBI.
