Seeing the importance of healthy diet after liver transplant (LT), our study aimed to evaluate the adherence to Mediterranean diet (MD) in a large population of LT recipients.
The present multicenter study was developed in clinically stable, liver transplanted patients, from June to September 2021. Patients completed a survey about adherence to MD, Quality of Life (QoL), sport, and employment. To analyze the correlations, we computed Pearson's coefficients; while to compare subgroups, independent samples t-tests and ANOVAs. We used a multivariable logistic regression analysis to find the predictors of impaired adherence to MD.
The questionnaire was administered to 511 patients. They were males in 71% of cases with a mean age of 63.1 years (SD±10.8). LT recipients coming from central Italy displayed higher adherence to the MD (M=11.10±1.91) than patients from northern (M=9.94±2.28, P<0.001) or southern Italy (M=10.04±2.16, P<0.001). Patients from central Italy showed a significantly higher consumption of fruit, vegetables, legumes, cereals, olive oil, fish and a significantly lower intake of dairy products than patients resident in the other Italian areas. At multivariate analysis, recipients from central Italy were 3.8 times more likely to report adherence to the MD. Patients with a high physical health score were more adherent to MD, as well as patients transplanted at an earlier time.
We demonstrated that place of stay, time from transplant and physical dimension of QoL significantly influences the adherence to MD. Continuous information campaigns about a correct diet and lifestyle would be necessary.
