Functional Recovery after Hip Fracture as a Function of Body Mass Index

Aims: To evaluate the association between body mass index (BMI) and functional recovery among hip fracture patients discharged from rehabilitation. Methods: We retrospectively analyzed data from patients in a orthogeriatric unit who were classified into four groups: underweight (BMI <18.5 kg/m(2)), normal weight (18.5 to <25), overweight (25 to 30), and obese (>= 30). Functional recovery was assessed using the Agence Technique de l'Information et de l'Hospitalization (ATIH) motor autonomy instrument and the Groupe Iso Ressource (GIR) scale. Results: Among 295 hip fracture patients, upon discharge, the ATIH and GIR scores improved. According to the ATIH score, 36% of the patients were very dependent on discharge (vs. 68% on admission). According to the GIR score, the corresponding values were 28% and 53%. There were no significant differences in functional recovery between BMI groups. Conclusions: In hip fracture patients, functional scores improved during hospitalization but were not influenced by the BMI.
