Analysis of characteristics of hospitalized patients with chronic insomnia: a single-center retrospective study

Objective: Insomnia is a prevalent health issue within the general population. Nonetheless, there is a paucity of research specifically addressing chronic insomnia among hospitalized patients. Consequently, the objective of this study is to investigate chronic insomnia in adult inpatients. Methods: A retrospective analysis was conducted on hospitalized patients at Fengjie County People's Hospital in Chongqing from January 2022 to June 2025. The study included patients aged 18 to 100 years, with comprehensive documentation of their demographic information, laboratory test results, and insomnia treatment details. Patients with incomplete data or those under 18 years of age were excluded from the study. The analysis focused on the age distribution, gender ratio, and BMI distribution of the patients, as well as the prevalence of primary diagnostic categories and the distribution characteristics of fasting blood glucose levels and dyslipidemia. Results: The study included a total of 871 patients, with a male representation of 39.6%. The mean body mass index (BMI) was 23.1 ± 3.7 kg/m², and the mean age was 64.1 ± 13.9 years. The predominant sources of disease were identified as infectious diseases, cardiovascular diseases, neurological disorders, tumors, and musculoskeletal conditions. A significant proportion of patients presented with elevated fasting blood glucose levels and dyslipidemia. Conclusion: Chronic insomnia in hospitalized patients predominantly affects elderly women. Chronic insomnia in hospitalized patients predominantly affects elderly women, who primarily present with infectious diseases, cardiovascular conditions, neurological disorders, tumors, and musculoskeletal issues. These patients often exhibit dyslipidemia and elevated fasting blood glucose levels, necessitating clinical attention.
