: Diet plays a crucial role in the regulation of chronic inflammation. The sparse evidence available in adult populations indicates that diet quality is linked to the dietary inflammatory potential; however, this association has not been established in youth. : Data were obtained from a representative national sample of 2889 children and young people in Spain, aged 6-24 years. The dietary inflammatory potential was measured by the dietary inflammatory index (DII), and diet quality by three conceptually different measures: the Mediterranean Diet Quality Index for children and adolescents (KIDMED), energy density, and total dietary antioxidants capacity. : The mean DII was 1.96 ± 0.76 units Scoring for the KIDMED index and the total dietary antioxidant capacity significantly decreased ( < 0.001 and = 0.030, respectively) across quintiles of the DII, whereas the opposite was true for energy density ( < 0.001). The effect size of these associations was strongest for energy density, followed by the KIDMED index and total dietary antioxidant capacity. : A healthy diet characterized by high adherence to the Mediterranean diet, high total dietary antioxidant capacity, or low energy density was linked to greater anti-inflammatory potential of the diet, as measured by the DII.
饮食在慢性炎症的调节中起着至关重要的作用。成年人群中现有的稀少证据表明，饮食质量与饮食炎症潜能相关；然而，这种关联在青少年中尚未得到证实。
数据来自西班牙2889名6至24岁儿童和年轻人的具有代表性的全国样本。饮食炎症潜能通过饮食炎症指数（DII）来衡量，饮食质量则通过三种概念上不同的指标来衡量：儿童和青少年的地中海饮食质量指数（KIDMED）、能量密度和总饮食抗氧化能力。
DII的平均值为1.96±0.76单位。在DII的五个五分位数中，KIDMED指数得分和总饮食抗氧化能力显著下降（分别为<0.001和=0.030），而能量密度则相反（<0.001）。这些关联的效应大小以能量密度最强，其次是KIDMED指数和总饮食抗氧化能力。
以高度遵循地中海饮食、高总饮食抗氧化能力或低能量密度为特征的健康饮食，与通过DII衡量的更大的饮食抗炎潜能相关。
