OBJECTIVE: To characterize weight change after amputation by identifying typical
weight trajectories in men with incident lower-limb amputation (LLA) and
describing characteristics associated with each trajectory. DESIGN: Retrospective
cohort study and analyzed using group-based trajectory modeling. SETTING: Administrative data. PARTICIPANTS: Veterans who were men (N=759), living in the
Northwest United States, and who had an incident toe, foot, or leg amputation
between 1997 and 2008 and at least 18 months of amputation-free survival thereafter. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Postamputation
weight and body mass index change. RESULTS: The mean weight at baseline was
91.6+/-24kg (202+/-53lb), and average follow-up was 2.4 years. We identified 4
trajectory groups for weight change: weight loss (13%), stable weight (47%), slow
weight gain (33%), and rapid weight gain (7%). Men with a toe or foot amputation
most frequently were assigned to the stable weight group (58%), whereas men with
transtibial or transfemoral amputations were most commonly assigned to the slow
weight gain group (42% each). Men who died during follow-up were more likely to
be assigned to the weight loss group (24%) than men who did not die (11%).
CONCLUSIONS: We identified distinct weight change trajectories that represent
heterogeneity in weight change after LLA. An improved understanding of factors
predictive of weight gain or loss in people with LLA may help better target
rehabilitation and prosthetic prescription. Additional research is needed to
fully understand the relation between weight change and health status after amputation.
