Abstract

The main purpose of this study is to investigate the important impacting factors of health-related quality of life (HRQOL) by different age groups. The subjects of this study were 5,976 adults over 19 based on data from the 2014 Korea National Health and Nutrition Examination Survey and EQ-5D index score was used for the measurement of HRQOL. Three age groups were considered of young (19-39), middle (40-65), and old (over 66) and for each age group Bayesian ordered probit model analysis was fitted to identify significant factors and their effects on HRQOL. Sex, subjective awareness of health, stress and diseases have been identified to be common important factors for all age groups. HRQOL of women is more likely to be lower than that of men. Subjective awareness of health affect positively but stress and diseases affect negatively on HRQOL. For middle age group, occupational activities have been found to be important positive factors on HRQOL. On the other hand, obesity is more important factor influencing on HRQOL negatively and frequent walking is recommended for old age group.

본 연구의 목적은 한국인의 연령대에 따라 건강관련 삶의 질에 주요한 영향을 주는 요인들의 효과를 분석, 비교하는 것이다. 연구대상은 2014년도 제 6기 국민건강영양조사자료에 참여한 19세 이상의 성인 5,976 명이며 EQ-5D 점수를 삶의 질에 대한 평가 척도로 이용하였다. 연령대는 젊은층(19세-39세), 중년층 (40세-65세), 노년층 (66세 이상)으로 나누었고 각 연령층에서 총 29개의 요인들에 대하여 베이지안 순서형 프로빗 모형을 이용하였다. 연구결과 전 연령대에서 공통적으로 삶의 질에 주요한 효과를 나타내는 요인은 성별, 건강에 대한 주관적 인식의 정도, 스트레스, 각종 질병요인들이다. 여성의 삶의 질은 남성보다 낮고 건강에 대한 주관적 인식의 정도가 높을수록 삶의 질이 높으며 스트레스는 삶의 질에 부정적 영향을 준다. 특히, 노년층에서 남녀간 차이와 건강에 대한 주관적 인식에 의한 차이가 두드러졌다. 질병은 삶의 질을 저하시키며 그 정도는 중년층, 젊은층, 노년층 순이다. 연령집단을 비교했을 때, 중년기에는 직업 활동이 삶의 질에 주요한 긍정적 효과를 나타내고, 노년기에는 앉거나 누워있는 시간이 많을수록, 비만 정도가 심할수록 삶의 질이 낮고 걷기를 자주 할수록 삶의 질이 높다.
