背景和目的：饮食炎症指数（DII）是衡量一个人饮食的整体炎症潜力的指标。然而，目前还没有研究观察DII对肌肉质量和力量的影响。我们的目的是研究DII与中国儿童骨骼肌质量和力量之间的关系。方法和研究设计：共有466名6-9岁的儿童完成了研究。采用双能x线吸收仪测定全身骨骼肌质量（TSM）、阑尾骨骼肌质量（ASM）和阑尾瘦肉质量（ALM）。计算TSM/ flight(2)、TSM/Weight、ASM/Height(2)、ASM/Weight。采用残差法计算经身高和体脂调整后的ALM指数（ALMI）。用手测力仪测定了手握力。DII得分是根据79项食物频率问卷计算的。结果：经完全调整的线性回归模型显示，DII与ASM、ASM/Height(2)、ASM/Weight、ALMI、TSM、TSM/Fleight(2)、TSM/Weight呈显著负相关（p:0.019 ~ 0.014）。协方差分析表明，上述措施的DII极端四分位数（Q4 vs Q1）的百分比差异范围为1.04% ~ 4.36% (p趋势：
Background and Objectives: The dietary inflammatory index (DII) is a measure of the overall inflammatory potential of a person's diet. However, there have been no studies looking at the effect of DII on measures of muscle mass and strength. We aimed to examine the association between DII and skeletal muscle mass and strength in Chinese children. Methods and Study Design: A total of 466 children aged 6-9 years completed the study. Total body skeletal muscle mass (TSM), appendicular skeletal mass (ASM) and appendicular lean mass (ALM) were determined using Dual-energy X-ray absorptiometry. TSM/Fleight(2), TSM/Weight, ASM/Height(2) and ASM/Weight were calculated. The residual method was applied to compute ALM index (ALMI) adjusted for height and body fat. Hand grip strength was measured using hand dynamometer. DII scores were calculated from a 79-item food frequency questionnaire. Results: Fully adjusted linear regression models showed a statistically significant negative relationship between DII and ASM, ASM/Height(2), ASM/Weight, ALMI, TSM, TSM/Fleight(2), and TSM/Weight (p:0.019-0.014). The analysis of covariance indicated that the percentage differences in the extreme quartiles (Q4 vs Q1) of DII for the above-mentioned measures ranged from-1.04% to-4.36% (p-trend:
