To clarify the causes of low QOL among South Koreans
at a national level, targeting adults 19 years of age or
older, we focused on marital status as one socioeconomic
issue and then analyzed its association with quality of life.
Some differences were evident depending on whether we
used EQ-5D or EQ-VAS, but we nonetheless observed
differences in quality of life depending on marital status in
men and women. The EQ-VAS scores of men were a
more sensitive indicator of the decline in the quality of life
that occurred with marriage problems than the decline
associated with single status. However, the decline in
QOL associated with single status was greater than that
associated with marriage problems using the EQ-5D.
