Factors related to quality of life among middle-aged and older korean adults in 2006 and 2014: A nationally representative study.

Factors related to quality of life (QoL) were investigated using data from middle-aged and older Korean respondents to the 2006 and 2014 Korean Longitudinal Study of Ageing. Respondents' QoL score in 2014 (6.03 ± 1.69) was lower than in 2006 (6.20 ± 2.12). All socio-demographic and health-related variables seemed to influence QoL in 2006 (R2 = 0.238) and 2014 (R2 = 0.234). Four factors significantly associated with QoL in both years were health, household income, depression, and regular exercise. Rural and mid-sized city dwellers were more likely to have a better QoL than residents of metropolitan areas; residential area had a greater influence on QoL in 2014.
