Abstract

This study was designed to measure the difference in health-related quality of life (HRQOL) among social classes and explore the factors that may explain it. Study subjects were 7,992 Korean adults aged 20-69 from the 4th (2007-2009) Korea National Health and Nutrition Examination Surveys data. We described mean value of EQ-5D index as a HRQOL by class and performed hierarchical multiple regression analysis to find the factors. The result was as follows. In the distribution of EQ-5D index level among social classes, new middle class (class II) had the highest score (0.966 in men and 0.955 in women); upper and middle-upper class (class I) 0.965 in men and 0.936 in women; working class (class IV) 0.958 in men and 0.936 in women; old middle class (class III) 0.955 in men and 0.932 in women; low class (class VI) 0.941 in men and 0.908 in women; and rural self-management class (class V) the lowest score (0.918 in men and 0.866 in women). In men, chronic disease, job stress, education and income level were found to make the difference in the health-related quality of life among social classes; in women, those factors and health behavior explained the difference. In conclusion, the lower social class has lower HRQOL. Except for education and income level, chronic disease may be the major factor to explain the difference in the health-related quality of life among social classes.

본 연구는 우리나라 성인의 사회계층별 건강관련 삶의 질 수준의 차이를 측정하고, 이러한 계층별 건강관련 삶의 질의 수준의 차이를 설명하는 요인을 파악하고자 하였다. 국민건강영양조사 제4기(2007년-2009년) 자료를 이용하여 20-69세 성인 7,992명을 대상으로 성별로 층화 분석한 결과는 다음과 같다. 건강관련 삶의 질 점수인 EQ-5D index의 사회계층별 분포를 보면, 남자에서는 신중간층(II계층)이 0.966점으로 가장 높았으며 상위 및 중상위계층(I계층)이 0.965점, 노동계층(IV계층) 0.958점, 구중간층(III계층) 0.955점, 하위계층(VI계층) 0.941점, 농촌자영자층(V계층) 0.918점 순이었다. 여자에서는 신중간층이 0.955점으로 가장 높았으며 상위 및 중상위계층이 0.955점, 노동계층 0.936점, 구중간층 0.932점, 하위계층 0.908점, 농촌자영자층 0.866점 순으로 계층 간 차이를 보였다. 위계적 회귀분석 결과 건강관련 삶의 질의 사회계층별 차이에 기여하는 요인은 남성의 경우 만성질환, 업무스트레스, 교육, 소득수준 등이었고, 여성의 경우 이들 변수와 함께 건강행태가 기여요인으로 파악되었다. 결론적으로, 낮은 사회계층일수록 낮은 건강관련 삶의 질을 보이며, 교육과 소득수준을 제외하면 만성질환 유병이 사회계층별 건강관련 삶의 질의 차이에 가장 큰 기여를 한 것으로 사료된다.
