Abstract
|
|
|
Objectives：We aimed to investigate the relation between poor quality of sleep and clinical characteristics in patients with schizophrenia.
Methods：Using the Korean version of the Pittsburgh Sleep Quality Index(PSQI-K), the sleep quality was evaluated in 118 patients with schizophrenia. Demographic and clinical variables were compared between schizophrenia patients with and without poor quality of sleep. Laboratory variables, clinical and sociodemographic characteristics were compared between PSQI-K score higher than 5 points group(PSQI-H) and PSQI-K score lower than 4 points group(PSQI-L).
Results：The prevalence of diabetes mellitus(DM) was higher in PSQI-H patients. In patients with DM, sleep duration was shorter and use of sleeping medication was more frequent than patients without DM. In logistic regression analysis, DM was associated with higher score of PSQI-K.
Conclusion：We have found that presence of DM can be associated with poor quality of sleep in patients with schizophrenia. Further studies with more objective assessment on sleep quality and mediation are needed to clarify these relationships between sleep quality disorder and diabetes mellitus.
