Factors that related with sleep disturbance among older nursing home residents with dementia

This study aimed to identify factors that related with sleep disturbance among older people with dementia in nursing homes. This cross-sectional study included 140 participants aged 60 years old and over, who were diagnosed with dementia (according to DSM 5 criteria) from November 2022 through January 2023 in 3 nursing homes in Hanoi, Vietnam. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The mean (SD) age among participants was 78.23 (8.73) and the female/male ratio was 1.5. The prevalence of poor sleep was 76.4% (n = 107). The poor sleep was significantly associated with depression (p = 0.007). The prevalence of poor sleep quality among the older people in nursing homes is relatively high. Depression is related to poor sleep quality among participants. Therefore, evaluating sleep quality among nursing homes should be performed as a basic clinical practice.
