Using preliminary data, we examined: (i) patterns of body mass index
(BMI) over the year following amputation by amputation level and (ii) the
association between BMI and mobility and prosthetic device use. METHOD: Patients
from three medical centers undergoing dysvascular amputation (N = 87; M age = 62)
participated in interviews pre-surgically and at 6 weeks, 4 months, and 12 months
following amputation. The main outcome was self-reported BMI, adjusting for limb
weight lost due to amputation. Additional outcomes were mobility and time spent
using and walking in a prosthetic device. RESULTS: Adjusted BMI slightly
decreased at 6 weeks (pre-surgery M = 31.2; 6 weeks M = 30.3) and 4 months (M =
30.7) but exceeded baseline levels by 12 months (M = 31.7). There were no
significant BMI differences by amputation level. In multivariable analyses,
higher pre-surgical BMI was associated with fewer hours of prosthetic device
walking at month 4 (beta = -0.49) and poorer overall mobility at month 12 (beta =
-0.22). CONCLUSIONS: BMI increased at one year following amputation surgery.
Higher pre-surgical BMI was associated with poorer mobility and prosthetic device
use. Interventions are needed to prevent excess weight gain in the year following amputation. REHABILITATION: * People undergoing lower-extremity
amputation have high rates of overweight and obesity and continue to gain weight
in the year following amputation. * Objective assessment of body mass index (both
with and without a prosthetic device) and waist circumference would help future research efforts. * Targeting weight loss post-amputation could improve the health of people with lower-extremity amputations.
