Abstract

Objectives: As a sequel to the former analysis of the quality of life (QoL) among young-old and old-old in Korea, this research was aimed to identify factors related to the quality of life and the gender difference after controlling for the related factors among Korean elderly. Methods: Selected elderly data of 1,339 subjects from the 5th Korea National Health and Nutrition Examination Survey conducted in 2010 was analyzed. In this survey, QoL was measured using Euro Quality of Life (EQ-5D) instrument. Data were analyzed using complex survey data analysis on IBM-SPSS 20.0. The related factors were identified using general linear models with backward elimination. The gender difference was tested also using general linear models. Results: The distributions of educational level, family income level, and presence of cohabitant were different between male and female elderly in both young-old and old-old age group. So were the health behaviors and perceived health, and experience of stress, depression, and suicidal thoughts. QoL and its subscales- mobility, self care, daily living, pain and discomfort, and anxiety and depression- were consistently better among male elderly regardless of age group. Among the variables considered, education, family income level, presence of cohabitant, perceived health, age group and BMI were found to be related to the QoL at p=.05, and presence of chronic diseases at p=.10. The difference in QoL between male and female elderly after controlling for the variables was statistically significant. Conclusion: Improving QoL is particularly important for the elderly. In order to improve QoL of the elderly, age- and gender- differences need to be considered when developing services and programs for the elderly.

본 연구는 노인의 삶의 질 관련 요인을 파악하고, 관련 요인을 통제한 상태에서 남 녀 노인의 삶의 질에 차이가 있는지 국민건강영양조사 제5기 1차년도 자료를 사용하여, 65세 이상 노인 1,339명을 대상으로 하였다. 자료분석 방법은 층과 집락 가중치를 지정하여 SPSS 20.0 복합표본분석방법으로 분석하였는데, 연령과 성별에 따른 일반적 특성과 건강행위 및 건강상태의 차이는 로지스틱회귀분석을, 삶의 질 차이는 일반선형모형분석을, 삶의 질 관련 요인은 후진제거방법을 이용한 일반선형모형으로 파악하였으며, 성별의 차이 역시 일반선형모형을 이용하여 검증하였다. 일반적 특성에서는 교육수준(p<.001)과 경제수준(p=.005), 동거여부(p<.001)가 성별에 따라 차이가 있었으나, 거주지역은 차이가 없었으며, 건강행위는 흡연(p<.001), 음주(p<.001), 운동(p=.045)에서 차이를 보였고, 건강상태에서는 비만정도(p<.001), 만성질환유무(p<.001), 스트레스(p<.001), 우울(p=.005), 자살사고(p<.001), 주관적 건강상태(p<.001)이 성별에 따라 차이가 있는 것으로 나타났다. EQ-5D는 노년전기, 후기 모두 여자노인보다 남자노인의 점수가 높았으며, 운동능력, 자가간호능력, 일상생활불편감, 통증/불편감, 불안/우울 등 모든 하위영역에서는 여자노인의 삶의 질이 남자보다 낮았다. 삶의 질 관련변수는 교육수준(p=.001), 경제상태(p=.001), 만성질환유무(p=.052), 동거여부(p=.002), 주관적 건강상태(p<.001), 연령(p<.001), BMI(p=.045)로, 이 변수들은 노인 삶의 질의 31.5%를 설명하였다. 노년기에서도 성 인지적 차이를 감안한 접근방안이 필요함을 제언한다.
