Regular cardiovascular (CV) exercise may counteract the exacerbated CV risks of immunosuppressive therapies and facilitate weight management. However, the efficacy of CV exercise is dependent on adequate adherence. Variables such as education and body fat have been found to be associated with exercise adherence, but their effect on adherence in liver transplant (LTX) patients is unknown.
To identify predictors of exercise adherence in LTX patients.
Eighty-two LTX recipients were assigned to a 10 month program of home-based cardiovascular exercise. The exercise goal was 5 per wk, ≥ 40 min, and 75–80% HRmax or an RPE of 15–17 by month ten. Telephone and/or email follow-up occurred at least monthly to assess current frequency (F), intensity (I), and duration (D) of activities. Additional follow-ups were conducted when exercise goals were not met, and strategies for overcoming barriers and increasing activity were provided. Adherence was calculated as the mean percentage of F, I, and D achieved at 10 months. Linear regression using adherence as the dependent variable and LTX waiting time, percent body fat, number of follow-ups, subjective rating of physical functioning (Karnofsky scale), and highest education level as the independent variables.
Significant independent variables were the number of follow-ups and subjective rating of physical functioning. (R2=.202; p < 0.05).
The variables associated with adherence in LTX patients differ from those reported in the general population.
