This study aimed to investigate the prevalence and risk factors of type 2 diabetes in individuals suffering from insomnia. A total of 1311 individuals referred for sleep examinations at a specialized sleep center were included in the study. Participants underwent comprehensive medical assessments, including sleep evaluations and blood tests to determine their diabetes status. The findings revealed a significant association between insomnia and type 2 diabetes, with a substantial proportion of participants being diagnosed with the metabolic disorder. Insulin resistance, a key precursor to diabetes, was also more prevalent among individuals with insomnia, indicating an increased risk of developing diabetes. Furthermore, the study highlighted the impact of sleep duration on diabetes risk among insomnia sufferers. Chronic insomnia and consistently insufficient sleep were associated with a higher likelihood of developing diabetes, suggesting that sleep duration is a modifiable factor influencing metabolic health. Obesity, a well-established risk factor for type 2 diabetes, was found to exacerbate the risk in individuals with both insomnia and obesity.
