The association between sleep quality and overall health has been extensively examined. However, few studies have investigated the relationship between sleep and the inflammatory potential of the diet. Thus, the purpose of the present study was to explore the association between the scores on the Energy-Adjusted Dietary Inflammatory Index (E-DII) and sleep quality in Lebanese university students. We conducted a cross-sectional study with students attending the Tripoli campus of Beirut Arab University. A total of 270 students aged between 17 and 25 years were randomly selected. All students filled out a multicomponent questionnaire that included an assessment of their sleep quality using the Pittsburg Sleep Quality Index, and of their physical activity level using the short version of the International Physical Activity Questionnaire. The scores on the E-DII were calculated based on a validated food frequency questionnaire. Individuals in the highest (most proinflammatory) quartile of the E-DII were at an increased risk of having poor overall sleep quality compared with the lowest quartile (odds ratio [OR] = 2.86; 95% confidence interval [95%CI]: 1.27-6.44). Regarding the individual domains of sleep quality, subjects in quartiles 3 and 4 of the E-DII were at an increased risk of having poor sleep efficiency compared with those in quartile 1 (OR = 2.49; 95%CI: 1.12-5.54; and OR = 2.52, 95%CI: 1.13-5.62 respectively). However, individuals in quartile 3 were at a reduced risk of having daytime dysfunction compared with those in the lowest quartile (OR = 0.44; 95%CI: 0.23-0.83). The inflammatory potential of the diet seems to be related to sleep quality in our sample of Lebanese university students. Future prospective studies are required to further explore this association.
睡眠质量与整体健康之间的关联已得到广泛研究。然而，很少有研究调查睡眠与饮食的炎症潜能之间的关系。因此，本研究的目的是探讨黎巴嫩大学生的能量调整饮食炎症指数（E-DII）得分与睡眠质量之间的关联。
我们对就读于贝鲁特阿拉伯大学的黎波里校区的学生进行了一项横断面研究。总共随机选取了270名年龄在17至25岁之间的学生。所有学生都填写了一份多成分问卷，其中包括使用匹兹堡睡眠质量指数评估他们的睡眠质量，以及使用国际体力活动问卷简版评估他们的身体活动水平。E-DII得分是根据一份经过验证的食物频率问卷计算得出的。
与最低四分位数相比，E-DII最高（炎症性最强）四分位数的个体总体睡眠质量较差的风险增加（优势比[OR]=2.86；95%置信区间[95%CI]：1.27-6.44）。关于睡眠质量的各个领域，与第一四分位数的受试者相比，E-DII第三和第四四分位数的受试者睡眠效率低下的风险增加（OR分别为2.49；95%CI：1.12-5.54和OR=2.52，95%CI：1.13-5.62）。然而，与最低四分位数的个体相比，第三四分位数的个体白天功能障碍的风险降低（OR=0.44；95%CI：0.23-0.83）。
在我们的黎巴嫩大学生样本中，饮食的炎症潜能似乎与睡眠质量有关。未来需要进行前瞻性研究以进一步探索这种关联。
