Purpose: The purpose of this study is to analyze difference in quality of life related to health according to our country’s social stratification.
Methods: This study had analytical subjects as 7,992 adults(4,557 men, 3,435 women), who are included in a variable by social stratification among 15,691 people in the age group of 20~69 years old as examinees, based on the 4th Korea National Health and Nutrition Examination Survey.
Results: This study obtained the following results. First, seeing the score of health-related life quality by social stratification, namely, the distribution of EQ-5D index, the new middle class(class II) was the highest(men with 0.966 point, women with 0.955 point). The agricultural self-employed class(class V) was indicated to be the lowest(men with 0.918 point, women with 0.866 point). In general, the more belonging to low social stratification led to having shown the lower aspect in EQ-5D index value. Second, as for the results of the hierarchical regression analysis, the factors of contributing to difference by social stratification in health-related quality of life were chronic disease, job stress, education, and income level in both men and women. The health behavior was grasped to be a factor of contributing only to women.
Conclusions: To reduce difference in health-related quality of life according to social stratification in the future, the continuous investment is needed for supporting socially high-quality education and economic stability. The sphere of health will need to be given priority to the prevention of chronic disease and the development in effective management policy for the lower classes.
