ObjectivesMetabolic syndrome (MetS) is a disorder in which obesity, insulin resistance, high blood pressure and dyslipidemia coexist. This study assessed the prevalence of MetS and its associated factors in patients who underwent orthotopic liver transplantation (OLTx).MethodsPost-OLTx patients were assessed for the presence of MetS according to the diagnostic criteria proposed by the International Diabetes Federation (IDF) and National Heart, Lung, and Blood Institute/American Heart Association (NHLBI/AHA). Demographic, socioeconomic, lifestyle, clinical, anthropometric, and dietary variables were collected to identify predictors for MetS using logistic regression analysis.ResultsAmong the 148 patients assessed, the prevalence of MetS was 50% (IDF criteria) and 38.5% (NHLBI/AHA criteria). For both the IDF and the NHLBI/AHA classifications, the independent factors associated with MetS were older age, shorter time since transplantation, and history of excessive weight prior to OLTx. Other predictors for MetS by IDF criteria were alcohol abuse as the indication for OLTx, physical activity reduction as the cause of weight gain after transplantation, and calcium intake below recommended levels. The presence of MetS (NHLBI/AHA) was also associated with decreased intake of potassium, fiber, and folic acid.ConclusionsMetS is highly prevalent among post-OLTx patients and it is predicted by older age, shorter time since transplantation, alcohol abuse as the cause of cirrhosis, excessive weight prior to OLTx, and some potentially modifiable factors such as physical activity reduction after OLTx and low intake of calcium, potassium, fiber, and folic acid.Copyright © 2011 Elsevier Inc.
