Background: This study examined the effect of housing affordability on the incidence of depression in Korean adults aged 45 years and above using the Korean Longitudinal Study of Aging (KLoSA).
Methods: Five-year data from wave two to wave six of the KLoSA provided by the Ministry of Labor were used. In the first year of KLoSA in 2006, among those who did not suffer from depression, ones who had one or more of the survey data from the second to the sixth were analyzed. generalized estimating equation (GEE) regression analysis and chi-square test were used as data processing methods.
Results: According to the 2010 data, out of 4,606 people, 3,558 (77.3%) were in the affordable group, and 1,048 (22.8%) in the experienced overburden group. The result of regression analysis with controlling general characteristics as covariates showed that the experienced overburden group had a higher incidence of depression than the affordable group. A longitudinal analysis of housing affordability and incidence of depression for five years revealed no significant difference in the incidence of depression. However, the overall share of overburden experience increased steadily. A comparison of the incidence of depression between the affordable and experienced overburden groups in each year showed that the incidence of depression was statistically higher each year.
Conclusion: Housing affordability increases the incidence of depression, and eight years of data indicated depression in the experienced overburden group to be higher than the affordable group.
