Objective: Our study aims to determine the rate of sleep disorders in elderly people aged 65 and older, living in nursing homes in Samsun, and also to investigate the factors affecting sleep quality through a comprehensive geriatric assessment. Methods: Our study was performed in the two largest nursing homes in Samsun province between March 1st and April 30th 2018. The sleep quality of the participating individuals was assessed by the Richard's Campbell Sleep Questionnaire (RCSQ) and the Epworth Sleepiness Scale (ESS). This individuals in our study were assessed using Geriatric Depression Scale (GDS), Mini-Mental State Examination (MMSE), Short Form 36 Health Survey (SF-36), Charlson Comorbidity Index (CCI). The obtained data were analyzed with SPSS 23.0 and p<0.05 was considered as significant. Results: A total of 84 people were included in the study and the mean age was 77.06 +/- 7.97 years. It was determined that 23.8% of the individuals had poor sleep quality at night according to RCSQ and 42.9% of the individuals had increased daytime sleepiness according to ESS. A significant statistical difference was found between the GDS scores with the RCSQ and ESS scores (p<0.001, p=0.001, respectively). The presence of depressive symptoms was associated with sleep quality at night and daytime sleepiness. A statistically significant difference was found between the MMSE and RCSQ scores (p=0.014). The presence of dementia was associated with sleep quality at night. Conclusions: The presence of depressive symptoms was found to cause poor sleep quality at night and increased daytime sleepiness. People with dementia had low sleep quality at night. The low life quality was found to associate poor sleep quality at night and increased daytime sleepiness.
