The aim of the study was to assess the capability of different
definitions of low appendicular lean mass (aLM) to predict the short-term
functional recovery in men with hip fracture. DESIGN: We investigated 80 of 95
men with hip fracture admitted consecutively to a rehabilitation hospital. Body
composition was assessed by dual-energy x-ray absorptiometry. Functional recovery
after inpatient rehabilitation was evaluated using Barthel Index scores. RESULTS:
The patients with aLM above the cutoff value of 19.75 kg indicated by the
Foundation for the National Institutes of Health (FNIH) had significantly higher
Barthel Index scores than those with aLM below the cutoff value (P = 0.002).
Patients' categorization according to the same threshold (aLM = 19.75 kg) was
significantly associated with a Barthel Index score of 85 or higher after
adjustment for age, cognitive impairment, hip fracture type, co-morbidities, and
medications (odds ratio = 7.17, 95% confidence interval = 1.43-35.94, P = 0.017).
Conversely, patients' categorization according to neither Baumgartner's cutoff
value (7.26 kg/m) for aLM/height nor Foundation for the National Institutes of
Health cutoff value (0.789) for aLM divided by body mass index was significantly
associated with the Barthel Index scores. CONCLUSIONS: Categorization according
to the Foundation for the National Institutes of Health threshold for aLM, but
not to the Foundation for the National Institutes of Health threshold for
aLM/body mass index or Baumgartner's threshold for aLM/height, was associated
with the short-term recovery in activities of daily living after a hip fracture in men.
