Diet may play a role in the regulation of obesity-related low-grade chronic inflammation.
Assess the association of the Dietary Inflammatory Index (DII) with anthropometric indicators of adiposity in Brazilian adolescents.
Data were collected from 71 740 adolescents (12-17 years old) examined in the Study of Cardiovascular Risks in Adolescents. Food consumption was assessed by means of one 24-h dietary recall, and DII was estimated using 39 food parameters. The body mass index (weight/height ) for age and sex was used to define overweight (>1 z-score). Abdominal obesity was indicated by waist circumference (WC) values >80th percentile and waist-to-height ratio (WHtR) > 0.50. The association between DII and anthropometric indicators was assessed using logistic regression models.
The mean DII score was higher in girls than in boys (0.77; SD = 0.04 vs. 0.04; SD = 0.05). Adolescents in the 4th quartile of DII, compared with those in the 1st quartile, had increased odds of being overweight (boys: OR = 1.76; 95% CI: 1.37; 2.25; girls: OR = 1.63; 95%CI: 1.36; 1.95), having abdominal obesity (boys: OR = 1.61; 95%CI: 1.33; 1.95; girls: OR = 1.73; 95%CI: 1.48; 2.03), and having high WHtR (boys: OR = 1.91; 95%CI: 1.52; 2.39; girls: OR = 1.75; 95%CI: 1.46; 2.11).
The findings showed a direct association between the dietary inflammatory potential measured by DII and adiposity.
饮食可能在肥胖相关的低度慢性炎症调节中发挥作用。
评估饮食炎症指数（DII）与巴西青少年肥胖人体测量指标之间的关联。
数据来自青少年心血管风险研究中检查的71740名青少年（12 - 17岁）。通过一次24小时饮食回忆评估食物摄入量，并使用39种食物参数估算DII。使用年龄和性别的体重指数（体重/身高）来定义超重（>1个标准差）。腰围（WC）值>第80百分位数和腰高比（WHtR）>0.50表示腹部肥胖。使用逻辑回归模型评估DII与人体测量指标之间的关联。
女孩的平均DII得分高于男孩（0.77；标准差 = 0.04对0.04；标准差 = 0.05）。与第一四分位数的青少年相比，DII第四四分位数的青少年超重几率增加（男孩：比值比 = 1.76；95%置信区间：1.37；2.25；女孩：比值比 = 1.63；95%置信区间：1.36；1.95），腹部肥胖几率增加（男孩：比值比 = 1.61；95%置信区间：1.33；1.95；女孩：比值比 = 1.73；95%置信区间：1.48；2.03），以及高WHtR几率增加（男孩：比值比 = 1.91；95%置信区间：1.52；2.39；女孩：比值比 = 1.75；95%置信区间：1.46；2.11）。
研究结果表明，通过DII测量的饮食炎症潜力与肥胖之间存在直接关联。
