Background: To investigate the relationship between daytime sedentary behavior and physical activity and sleep in patients with chronic schizophrenia, particularly focusing on insomnia symptoms, a hallmark of insomnia in patients with schizophrenia.Method: The subjects were 20 patients with chronic schizophrenia more than 1 year after onset (12 men and 8 women with a mean age of 59.0 ± 9.8 years), of whom 4 were outpatients and 16 were inpatients. Sedentary behavior performance and physical activity index (Total sedentary behavior time and sedentary behavior bout number, low-intensity physical activity, MVPA, and steps) were assessed by wearing a triaxial accelerometer (GT3X-BT). Total bed time (TIB), total sleep time (TST), sleep latency (SIL), wake after sleep (WASO), and sleep efficiency (SE) were calculated using a small body dynamometer as an objective sleep index. Both the triaxial accelerometer and the small body dynamometer were worn for 1 week, and the average value of each index was calculated.Results: Total sedentary behavior time was significantly positively associated with TIB and SL (r =. 499, p Conclusion: Daytime sedentary behavior in patients with chronic schizophrenia was associated with insomnia symptoms. It was suggested that decreasing their sedentary behavior time and increasing moderate-to-vigorous intensity activities may improve their sleep quality.In this study, though the relation has not been recognized in CP conversion value and sedentary behavior position action index, the relation between antipsychotic dose and total sedentary behavioral time needs further investigation. |
