Related Factors to Sleep Quality in Older Adults with Mild Cognitive Impairment at Long Term Care Hospitals in South Korea: A Cross-Sectional Study

Abstract

Purpose: The purpose of this study was to investigate the level of sleep quality among older adults with mild cognitive impairment (MCI) at long-term-care (LTC) hospitals and identify the related sleep-quality factors.Methods: This study was a descriptive study. A total of 150 older adults with MCI at 5 LTC hospitals participated in this study. Data analysis was conducted using descriptive analysis, t-test, ANOVA, Pearson's correlation and stepwise multiple regression with SPSS/20.0 program.Results: The significant related factors to sleep quality of older adults with MCI at LTC hospitals were shown as pain (β=.44, p<.001), environment (β=.26, p<.001) and number of diseases (β=.14, p=.032). Total explained variance was 39.8% (F=4.67, p=.032).Conclusion: Nursing care to control pain and number of disease in older adults with MCI must be developed for improving LTC hospitals’ environments and residents’ sleep quality. This study provides the basic data to develop sleep management programs of MCI older adults at LTC hospitals.
