Mental and Physical Readiness for Weight Loss After Abdominal Organ Transplant

Readiness to incorporate healthy lifestyle practices is not studied in posttransplant patients. We evaluate physical and mental readiness for a weight-loss guided lifestyle intervention.

12 kidney and 12 liver transplant patients were given a Fitbit and weighing scale for 12 mo. Twelve patients received group sessions on lifestyle modifications. Mental readiness was assessed using Patient Activation Measurement-13, Physical Activity, Process of Change, and Weight Stages of Change. Physical readiness was assessed using Fatigue, Resistance, Ambulation, Illness, and Loss of Weight, and Short Physical Performance Battery questionnaires. Weight change, group session attendance, device usage, and readiness were analyzed.

23 patients (12 kidney, 11 liver), 57 y (46.2-67.5), 75% male, 24.9 (15.7-43.2) months posttransplant) completed the study. Twenty-two patients had robust physical readiness, and high Fitbit usage (>80%). Ten patients (43%) lost ≥2.5% (moderate) of body weight, including 4 (17.3%) losing >5% total weight (high). 13 patients lost ≤2.5% or gained weight (maintenance). High loss and target group session attendance groups had the highest use of Processes of Change.

Posttransplant patients are physically ready for a weight-loss guided lifestyle intervention and show high usage of the Fitbit device. Higher mental readiness associates with higher weight loss.
