Abstract

Background and ObjectiveThe Korean version of the EQ-5D-Y was launched in 2015 by the EuroQol group. Currently, there is no HRQOL data obtained by using the EQ-5D-Y in Korea. This study aimed to measure health-related quality of life of Korean elementary school students using the EQ-5D-Y.MethodsElementary school students were recruited from 11 primary schools in Gyungbuk, South Korea. The EQ-5D-Y was self-administered in the sample population. Demographic characteristics were collected from the subjects’ parents or guardians. The percentage of respondents reporting problems and VAS scores were calculated. Feasibility of the EQ-5D-Y was assessed by analysing the proportion of missing responses. The percentage of reported problems on the dimensions and VAS score between groups were compared by demographic factors.ResultsA total of 2,494 questionnaires were collected. There were 24 (0.96%) missing responses on the EQ-5D-Y and 187 (7.5%) missing VAS score responses. The proportion of reported problems ranged from 2.3% on the mobility dimension to 9.8% on the “having pain or discomfort” dimension. There was no significant difference in the proportion of problems by age group in male participants. However, in females, the older group reported significantly more problems on the “having pain or discomfort” and “feeling worried, sad, or unhappy” dimensions compared to the younger group. Students living with parents with the lowest educational level reported significantly more problems on the “looking after myself” and “doing usual activities” dimensions than did those living with parents with higher levels of education.DiscussionThis study showed the distribution of health-related quality of life and explored the feasibility of the EQ-5D-Y for measuring health-related quality of life in Korean elementary school students. Further studies are required to examine other psychometric properties of the Korean EQ-5D-Y.

Highlights

Interest in health-related quality of life (HRQOL) as an outcome measure in children and adolescents has increased in recent decades in both clinical and community-based research (Higginson & Carr, 2001; Solans et al, 2008)
The use of the EQ-5D-Y Korean version in this study was approved by the EuroQoL group
There was no invalid answer on the EQ-5D-Y descriptive system or EQ visual analogue scale (EQ VAS)

Summary

Introduction

Interest in health-related quality of life (HRQOL) as an outcome measure in children and adolescents has increased in recent decades in both clinical and community-based research (Higginson & Carr, 2001; Solans et al, 2008). Generic instruments can be applied to a wide variety of populations They allow for broad comparisons of the relative impact of various health care interventions or comparisons of HRQOL between healthy and ill children (Fayers & Machin, 2000). Disease-specific instruments can be more sensitive at detecting clinically important differences or changes in specific disease groups (Wiebe et al, 2003) They cannot measure the HRQOL of patients without the specific disease (e.g., cancer), and it is not possible to compare the HRQOL of patients with other diseases (e.g., diabetes mellitus) or of a healthy population. This study aimed to measure health-related quality of life of Korean elementary school students using the EQ-5D-Y. The percentage of reported problems on the dimensions and VAS score between groups were compared by demographic factors. Further studies are required to examine other psychometric properties of the Korean EQ-5D-Y
