Evidence indicates that most college students face reduced sleep quality due to unhealthy dietary habits and hectic daily schedules. While the relationship between sleep quality and general health has been the subject of intensive research, little is known about the association between sleep and its relation with the inflammatory potential of the diet until recently. This study aimed to investigate the association between Energy-Adjusted Dietary Inflammatory Index (E-DII) scores and sleep quality in a group of students from the University of Sharjah (UOS).
A cross-sectional study design was followed, and convenience sampling was used. Participants were assessed for sleep quality using the Pittsburgh Sleep Quality Index (PSQI), E-DII scores were derived from a semi-quantitative food frequency questionnaire (FFQ), and physical activity level was measured using the International Physical Activity Questionnaire (IPAQ). Chi-square tests and two-sample t tests were used to find an association between E-DII scores and sleep quality.
A total of 379 college students were included in the study of whom 64 % were female and 81% were between 18 and 21 years of age. Two-thirds of participants experienced poor sleep quality. Although results were trending in the hypothesized direction, no significant association was found between E-DII scores and sleep quality. Among the individual components of sleep quality, a direct significant association was found between E-DII scores and day dysfunction (P = 0.03).
These results suggest that a pro-inflammatory diet maybe related to increased day dysfunction among UOS students. Consuming a more anti-inflammatory diet may reduce daytime dysfunction. Further prospective and controlled studies are required to confirm this association, and to explore other attributes and their sequelae on sleep quality.
有证据表明，由于不健康的饮食习惯和繁忙的日程安排，大多数大学生的睡眠质量都有所下降。虽然睡眠质量与整体健康之间的关系一直是密集研究的主题，但直到最近，人们才了解到睡眠与饮食的炎症潜力之间的关联。本研究旨在调查沙迦大学（UOS）一组学生的能量调整饮食炎症指数（E-DII）评分与睡眠质量之间的关系。
采用横断面研究设计，并采用便利抽样法。使用匹兹堡睡眠质量指数（PSQI）评估参与者的睡眠质量，从半定量食物频率问卷（FFQ）中得出 E-DII 评分，使用国际体力活动问卷（IPAQ）测量体力活动水平。使用卡方检验和两样本 t 检验来发现 E-DII 评分与睡眠质量之间的关联。
共有 379 名大学生参与了研究，其中 64%为女性，81%的年龄在 18 至 21 岁之间。三分之二的参与者睡眠质量较差。尽管结果朝着假设的方向发展，但 E-DII 评分与睡眠质量之间没有显著关联。在睡眠质量的各个组成部分中，E-DII 评分与日间功能障碍之间存在直接显著关联（P=0.03）。
这些结果表明，促炎饮食可能与 UOS 学生日间功能障碍增加有关。摄入更抗炎的饮食可能会减少白天的功能障碍。需要进一步进行前瞻性和对照研究来证实这种关联，并探索其他属性及其对睡眠质量的影响。
