재가노인의 수면 관련요인

Purpose: Reported insomnia and decreased sleep quality are common among older adults. The purpose of this study was to identify factors contributing to insomnia and decreased sleep quality among elderly persons living within a community. The data will be verified with Actigraph which is a non-invasive measurement of rest/activity cycles. Methods: 137 participants over 65 years old were recruited from a senior welfare center. Their mean age was $74.07{\pm}5.18years$ old and majority was women (69.3%). The quality and quantity of nighttime sleep were assessed using Varren-synder-Halper Sleep Scale and a sleep log. Depression and fatigue were assessed using Geriatric Depression Scale Short Form and Fatigue Severity Scale, respectively. Pain was assessed using 11-point Numeric rating scale. An actigraph was used to verify the self-reported sleep. Results: Ninety-two participants (67.2%) reported insomnia. Sixty-eight subjects (49.6%) reported good sleep. Of the participants, 56.2% reported depression and 33.6% reported fatigue. In logistic regression, depression was related to insomnia (OR=3.09, p=.003). Sleep quality was related to depression (OR=2.13, p=.045) and fatigue (OR=2.24, p=.044). The data from the Sleep logs correlated with data obtained from the actigraph. Conclusion: Depression significantly influenced insomnia and sleep quality whereas fatigue only influenced sleep quality. Thus, depression and fatigue should be closely monitored among elderly persons with sleep disturbances.
