The term metabolic-associated fatty liver disease (MAFLD) has been proposed to define positively fatty liver disease in the form associated with metabolic risk factors. The aim of this study was to assess the dietary intake of MAFLD and explore a possible relationship between its inflammatory characteristics (assessed by Dietary Inflammatory Index-DII), the degree of liver fibrosis (assessed by transient elastography), and the amount of alcohol intake. MAFLD patients were included ( = 161) and were classified, according to the amount of alcoholic intake, as MAFLD without alcohol intake ( = 77) and MAFLD with alcohol intake ( = 84), with 19 presenting harmful alcoholic consumption. Dietary intake was 1868 ± 415 kcal/day and did not present differences in energy or nutrient intake based on the presence of metabolic comorbidities. Patients with MAFLD and alcohol intake consumed significantly more energy and presented a tendency for higher intake of carbohydrates and sugar. Patients with harmful alcohol intake presented a higher intake of total fat and cholesterol compared with moderate alcohol intake. There were no differences in DII based on fibrosis severity or the amount of alcohol consumption. This work contributes to the characterization of baseline dietary intake in MAFLD patients, paving the way to design more suited dietary interventional trials.
代谢相关脂肪性肝病(MAFLD)这一术语被提议用于定义与代谢风险因素相关的脂肪性肝病。本研究旨在评估 MAFLD 的饮食摄入,并探讨其炎症特征(通过饮食炎症指数-DII 评估)、肝纤维化程度(通过瞬时弹性成像评估)和酒精摄入量之间可能存在的关系。纳入 MAFLD 患者(n=161),并根据酒精摄入量进行分类,分为无酒精摄入的 MAFLD(n=77)和有酒精摄入的 MAFLD(n=84),其中 19 例存在有害饮酒。饮食摄入量为 1868±415kcal/天,基于代谢合并症的存在,能量或营养摄入没有差异。有酒精摄入的 MAFLD 患者消耗的能量明显更多,且碳水化合物和糖的摄入量有升高的趋势。与适量饮酒相比,有害饮酒者的总脂肪和胆固醇摄入量更高。基于纤维化严重程度或酒精摄入量,DII 没有差异。这项工作有助于对 MAFLD 患者的基线饮食摄入进行特征描述,为设计更适合的饮食干预试验铺平了道路。
