To determine the association between food insecurity and Dietary Inflammatory Index (DII) in high school girls. This cross-sectional study was conducted on 525 students aged 14-18 years in northern Iran. Dietary assessment was performed using a validated and reliable 147-food item questionnaire. DII was calculated on the basis of 30 available food parameters from this FFQ based on the standard means. The USDA 18-item standard food security questionnaire was used to assess the food security status. Linear regression was performed to determine the association between DII and food insecurity, with DII considered as an outcome and food security score as an exposure. The average age of students was 16.13 ± 0.97 year. Mean BMI and menarche age was 22.64 ± 4.62 kg/m and 12.59 ± 1.09 year. The mean value of DII was -0.003 ± 1.72. Food insecurity prevalence was 40.8%. Protein, and vitamin D and B12 intake were lower in the food insecure group (P < 0.05). Energy intake, total fat and saturated fatty acid (SFA) were higher in the highest tertile vs. the lowest tertile of DII (P < 0.05). Carbohydrate, protein, fiber, magnesium, zinc, folate, selenium, vitamin A, B6, and C, thiamin, riboflavin, niacin and tea intake were lower in the highest tertile vs. the lowest tertile of DII (P < 0.05). There was a positive significant association between DII and food security status. It seems there is an association between DII and food security status. However, further well-designed studies in a different population are suggested.
探讨食物不安全感与青少年女生膳食炎症指数（DII）的相关性。 本横断面研究在伊朗北部选取了 525 名年龄在 14-18 岁的女学生。采用经过验证和可靠的 147 种食物项目问卷进行膳食评估。DII 是根据 30 种基于标准均值的可获得食物参数，通过该 FFQ 计算得出。采用美国农业部 18 项标准食物安全问卷评估食物安全状况。采用线性回归分析 DII 与食物不安全感之间的关系，将 DII 作为因变量，食物安全评分作为自变量。 学生的平均年龄为 16.13±0.97 岁。平均 BMI 和初潮年龄分别为 22.64±4.62kg/m 和 12.59±1.09 岁。DII 的平均值为-0.003±1.72。食物不安全感的患病率为 40.8%。在食物不安全组，蛋白质、维生素 D 和 B12 的摄入量较低（P<0.05）。在 DII 最高 tertile 组，能量摄入、总脂肪和饱和脂肪酸（SFA）高于最低 tertile 组（P<0.05）。在 DII 最高 tertile 组，碳水化合物、蛋白质、纤维、镁、锌、叶酸、硒、维生素 A、B6 和 C、硫胺素、核黄素、烟酸和茶的摄入量低于最低 tertile 组（P<0.05）。DII 与食物安全状况之间存在显著正相关。 看来 DII 与食物安全状况之间存在关联。然而，建议在不同人群中进行进一步设计良好的研究。
