Research has shown that diet has a significant impact on sleep quality. Diet plays an important role in regulating inflammation. The Dietary Inflammatory Index(DII) is related to the level of inflammation in the body, which is determined by various substances. The present review aimed to clarify the association between DII and sleep quality.</span></span></span></span><br> <span style="unicode-bidi:embed"><span style="line-height:115%"><b><span style="line-height:115%"><span style="color:black">Search Strategy:</span></span></b> <span style="line-height:115%"><span style="color:black">The present systematic review was prepared according to the PRISMA protocol. A search was conducted on the Persian (SID and Magiran) and English (PubMed, Medline, Web of Science, Google Scholar, Scopus) databases from 2010 to October 27, 2023. After searching all databases, 383 articles were identified. After reviewing the titles and abstracts, 60 articles were selected for reviewing their full text. In the end, in terms of the inclusion criteria, 16 articles were included in this systematic review.</span></span></span></span><br> <span style="unicode-bidi:embed"><span style="line-height:115%"><b><span style="line-height:115%"><span style="color:black">Results: </span></span></b><span style="line-height:115%"><span style="color:black">A total of 16 studies met the inclusion criteria and were included in this systematic review. According to the studies, there were nine cross-sectional studies, in which seven showed a significant relationship between DII and sleep quality. It was observed that each unit increases DII score change, increases WASO, decreases sleep efficiency, and delays sleep and waking time. Also, the results showed that this relationship is vital in women, elders, and people with chronic diseases. Seven Case-control studies revealed that diets rich in anti-inflammatory foods have a potential protective effect on sleep quality. Moreover, these studies highlighted the role of inflammatory markers such as C-reactive protein (CRP) and interleukin-6 (IL-6) in this regard.</span></span></span></span><br> <b><span style="line-height:115%"><span style="color:black">Conclusion and Discussion:</span></span></b><span style="line-height:115%"><span style="color:black"> According to the findings, DII and sleep quality have a significant association, and several studies have proven the effect of DII on sleep quality. However, due to the differences in race, weather conditions, and the number of people studied, this issue cannot be definitively stated, and more studies are needed in this field.</span></span></span></span></div> <br> <span style="font-family:Times New Roman;"><img alt="" src="./files/site1/images/888.jpg" style="width: 1000px; height: 36px;" ></span> Diet, Inflammation, Sleep quality 93 93 http://ibj.pasteur.ac.ir/browse.php?a_code=A-10-4696-97&slc_lang=other&sid=1 Arian Bandari Yes Vahideh Aghamohammadi No Sina Mohammadian No Amirhosein Chamani No Erfan Tarighi No Mohammadehsan Nezamloo No Amirhosein Ebrahimi No
