ABSTRACT

【Abstract】Objective To investigate the sleep disorder in elderly patients with schizophrenia (SZ) and analyze its influencing factors.
Methods Clinical data of 121 elderly patients with SZ treated in our hospital from June 2022 to June 2024 were retrospectively analyzed according to the Pittsburgh sleep quality index (PSQI). SZ patients were divided into sleep disorder group 66 cases (PSQI≥7 points) and no sleep disorder group 55 cases (PSQI < 7 points). Relevant baseline data, Positive And Negative Syndrome Scale (PANSS) scores and Montgomery-Asberg Depression Rating Scale (MADRS) were compared between the two groups. The risk factors of sleep disorders in elderly patients with SZ were analyzed by multiple factors.
Results Age, PANSS-P score, PANSS-G score and total MADRS score in sleep disorder group were higher than those in no sleep disorder group (P＜0.05). Multivariate Logistic regression analysis confirmed that old age, PANSS-P score, PANSS-G score and MADRS total score were risk factors for sleep disorders in elderly patients with SZ, all with P＜0.05.
Conclusion   Elderly SZ patients are prone to sleep disorders, and old age, PANSS-P score, PANSS-G score and MADRS total score are all influential factors of sleep disorders in elderly SZ patients, which should be paid sufficient attention to clinically.
