Abstract

Background: Thailand has shifted to an aging society. Sleep disturbance is a common problem in the elderly which affects emotion and cognitive levels. Awareness of sleep problems can help implementing elderly care and preventing dementia in the future.

Objective: To study sleep quality and determine factors associated with sleep quality among patients with mild cognitive impairment (MCI).

Methods: The cross-sectional descriptive study was conducted in MCI patients, aged 50 years and above, from a psychiatric outpatient clinic and cognitive fitness center. The data were collected by questionnaires including demographic data and sleep environment questionnaires; Pittsburgh Sleep Quality Index (PSQI); Sleep Hygiene Index (SHI); STOP-Bang questionnaire; Thai Mental State Examination (TMSE); Montreal Cognitive Assessment (MoCA); Thai Geriatric Depression Scale (TGDS), and Neuropsychiatric Inventory Questionnaire (NPI-Q). The sleep quality was presented as frequency and percentage. The associated factors were analyzed by Chi-square test, Fisher’s exact test, and Pearson’s correlation coefficient. The predictors of poor sleep quality were analyzed by multiple logistic regression analysis.

Results: Of the 100 subjects, 65 were female with a mean age of 71.3  7.5 years old: 64% of them had poor sleep quality. The associated factors of sleep quality were having a history of psychiatric disorders, use of sedating psychotropic drugs, low to moderate sleep hygiene, and anxiety domain of neuropsychiatric symptoms. TGDS and STOP-Bang scores were correlated with PSQI scores (r = 0.215 and 0.230, respectively). The predictors of poor sleep quality were the use of sedating psychotropic drugs (P < 0.01), low to moderate sleep hygiene (P < 0.05), and anxiety domain of neuropsychiatric symptoms (P < 0.05).

Conclusion: The prevalence of poor sleep quality in MCI patients was 64%. The associated factors and predicted factors of poor sleep quality were the use of sedating psychotropic drugs, low to moderate sleep hygiene, and anxiety domain of neuropsychiatric symptoms. Therefore, sleep quality should be screened in patients with MCI due to the high prevalence.
