Intestinal flora composition and fecal metabolic phenotype in elderly patients with sleep disorders combined with type 2 diabetes.

Objectives: This study aimed to determine whether type 2 diabetes (T2D) is an independent risk factor for sleep disorders in the elderly and explore the possible intestinal flora factors of sleep disorders combined with T2D in this population.

Methods: All hospitalized patients with sleep disorders aged ≥65 years between June and November 2023 were retrospectively analyzed, and they were divided into a sleep disorder group ( = 134) and a control group ( = 109). The logistic regression method was utilized to clarify the causal relationship between T2D and sleep disorders.
