The association between higher adherence of DII and DIL with sleep quality index and circadian rhythm status

DII: dietary insulin index, DIL: dietary insulin load

All data are presented as OR and 95% Cl by binary logistic regression

Adjustment model: based on age, energy intake and IPAQ

Low adherence of DII and DIL, good sleep quality, and normal circadian rhythm group were considered as reference group

P−values ≤ 0.05 were considered significant
