Conclusions
In conclusion, the findings of the present study showed that higher DII score was significantly associated with poor sleep (PSQI>5). After adjustment, participants in the highest quartile of DII score had significantly higher PSQI global score. There was no significant association between DII score and obesity. Our findings underscored the importance of eating an anti-inflammatory diet for good sleep. Future studies with prospective designs, larger sample size and considering more food parameters in the computation of the DII score, should be carried out to clarify this relationship.
