Abstract

The purpose of this study is to investigate the factors affecting sleep quality, depression, and stress on cognitive function in community-dwelling insomnia elderly people. The subjects of the study were 111 elderly registered at a senior center and welfare center in S City who were over 60 years old and complained of insomnia for the past 3 months or more. Self-report questionnaires and the Montreal Cognitive Assessment(Moca-K) were administered. Data were analyzed using SPSS Statistics 25.0 was used for data analysis, and the Pearson's correlation coefficient for the correlation between variables, and multiple regression analysis was used to determine influential factors. As a result of the study, cognitive function was significantly related to sleep quality(r=-0.45, p<.001), depression (r=-0.32, p<.001), and stress(r=-0.56, p<.001). showed a correlation. Predictive factors for cognitive function were identified as sleep quality and stress, and the explanatory power of these variables was found to be 35.0%. Based on these research results, it is necessary to develop a intervention program that can manage sleep quality and psychological symptoms to improve cognitive function in insomnia elderly people living in the community.

본 연구의 목적은 지역사회 거주 불면증 노인의 수면 질, 우울, 스트레스가 인지기능에 미치는 영향요인을 조사하는 것이다. 연구대상자는 S시 소재 시니어센터와 복지관에 등록된 노인 가운데 60세 이상이며, 최근 3개월 이상 불면증을 호소하는 111명을 대상으로 수면 질, 우울, 스트레스 및 인지기능을 평가하였다. 자료분석은 SPSS 25.0을 이용하여 변수 간의 상관관계는 Pearson's correlation coefficient를 산출하였으며 영향요인은 multiple regression 분석을 이용하였다. 연구결과, 인지기능은 수면의 질(r=-0.45, p<.001), 우울(r=-0.32, p<.001), 스트레스(r=-0.56, p<.001)와 유의한 음의 상관관계를 나타냈다. 인지기능의 예측요인은 수면 질, 스트레스로 확인되었으며 이들 변인의 설명력은 35.0%로 나타났다. 이와 같은 연구결과를 바탕으로 지역사회 거주 불면증 노인의 인지기능 향상을 위한 수면 질과 심리적 증상을 관리할 수 있는 중재 프로그램 개발이 필요하다.
