背景:饮食成分或其整体特性会影响个体的睡眠状态。
目的:这项研究的目的是批判性地寻找,评价,并综合了膳食炎症指数(DII)与睡眠质量及其参数之间关联的研究证据。
方法:关于成人的原始发表研究来自PubMed,Scopus,ScienceDirect,科克伦图书馆,和谷歌学者数据库。
方法:搜索没有日期限制,直到2023年4月。筛选出重复和不相关的调查,其余文章的结果进行了描述性总结,然后进行批判性评估和分析。关于饮食的可能机制途径,全身性炎症,和睡眠状态进行了讨论。
方法:在搜索的102项研究中,23篇文章(n=4项队列研究,18项横断面研究,和1项干预研究)纳入最终审查。在21项研究中主观调查了DII与睡眠状态之间的关联,在6项研究中进行了客观调查。研究的主要睡眠结果是睡眠质量,持续时间,延迟,效率,呼吸暂停,干扰,使用安眠药,白天功能障碍,睡眠开始后的觉醒,和快速的眼球运动。
结论:根据大多数证据,DII可能与整体睡眠质量无关,睡眠持续时间,延迟,效率,和使用安眠药。DII评分高(促炎饮食)与日间功能障碍之间的正相关证据更大,睡眠开始后的觉醒,和睡眠呼吸暂停。没有足够的证据就睡眠障碍和快速眼动做出任何结论。
BACKGROUND: Dietary components or its overall properties can influence an individual\'s sleep status.
OBJECTIVE: The aim for this study was to critically search, appraise, and synthesize research evidence on the association between dietary inflammatory index (DII) and sleep quality and its parameters.
METHODS: Original published studies on adults were obtained from the PubMed, SCOPUS, ScienceDirect, Cochrane Library, and Google Scholar databases.
METHODS: The search was conducted without date limitation until April 2023. Duplicated and irrelevant investigations were screened out, and the results of the remaining articles were descriptively summarized, then critically appraised and analyzed. Possible mechanistic pathways regarding diet, systemic inflammation, and sleep status were discussed.
METHODS: Of the 102 studies searched, 23 articles (n = 4 cohort studies, 18 cross-sectional studies, and 1 intervention study) were included in the final
review. The association between DII and sleep status was investigated subjectively in 21 studies and objectively in 6 studies. The main studied sleep outcomes were sleep quality, duration, latency, efficiency, apnea, disturbances, the use of sleeping medications, daytime dysfunctions, wakefulness after sleep onset, and rapid eye movement.
CONCLUSIONS: According to most of the evidence, DII may not be related to overall sleep quality, sleep duration, latency, efficiency, and the use of sleeping medications. The evidence of positive association was greater between a high DII score (pro-inflammatory diet) with daytime dysfunctions, wakefulness after sleep onset, and sleep apnea. There is insufficient evidence to make any conclusion regarding sleep disturbances and rapid eye movement.
