Abstract

The purpose of this study was to examine the mediating effect of stress on the relationship between oral health behaviors and health-related quality of life (HRQOL) in the elderly. We analyzed 8148 subjects aged 65 or older who participated in the Korea National Health and Nutrition Examination Survey (2010-2015). All individuals were asked about their socioeconomic history, general health, and oral health behaviors (the frequency of tooth brushing, regular dental check-ups, and use of interdental cleaners). In the results, HRQOL was low in the elderly from a low socioeconomic class, or with diabetes mellitus, hypertension, or poor oral health behaviors. A partial mediating effect from stress was confirmed on the relationship between oral health behaviors and HRQOL. In conclusion, HRQOL was associated with oral health behaviors, with a mediating effect from stress. Therefore, it is necessary that a convergence health promotion program should be planned with an oral health education program and a stress management program for the elderly.

본 연구는 노인의 구강보건행위가 건강관련 삶의 질(Health-related Quality of Life, HRQOL)에 미치는 영향에서 스트레스의 매개 효과를 분석하기 위하여 국민건강영양조사(2010-2015)를 활용한 이차 자료분석 연구이다. 65세 이상 노인 8,148명을 대상으로 사회 경제상태, 건강 상태, 흡연 및 음주 습관, 스트레스 여부, 그리고 구강보건행위(칫솔질 횟수, 정기적인 치과 검진여부, 치간 세정도구 사용)를 조사하였으며 건강관련 삶의 질 측정을 위해 EuroQol-5 Dimension(EQ-5D) index를 사용하였다. 연구결과, 사회경제학적 수준이 낮거나 고혈압, 당뇨병을 가진 노인들에서 HRQOL이 낮았으며, 칫솔질 횟수가 적거나 정기적인 치과방문을 하지 않거나 치간 세정도구를 사용하지 않는다고 응답한 노인들에서 HRQOL이 낮았다. 그리고 스트레스는 노인의 삶의 질에 부적 상관을 보였으며 구강보건행위와 삶의 질의 관계에서 부분매개효과를 확인하였다. 이러한 결과는 노인의 구강보건행위와 삶의 질의 관계에서 스트레스 매개효과가 있음을 의미한다. 그러므로, 노인의 건강관련 삶의 질 증진을 위해 건강증진프로그램을 수행할 때 스트레스 해소 및 구강건강증진 프로그램을 포함한 융합적인 프로그램이 필요하며, 그러한 정책마련을 위한 기초자료로 제공하고자 한다.
