The Dietary Inflammatory Index (DII) reflects the pro-inflammatory potential of the diet, but its association with sleep disorders among individuals with hyperlipidemia remains unclear.

Sleep disorders were defined based on self-reported physician diagnosis. DII scores were calculated based on 22 dietary components.
