The Impact of Depression on Ill-Health Retirement and Its Moderating Factors: Analysis From the Korean Longitudinal Study of Aging (2006 to 2014)

OBJECTIVE:To investigate the effect of depressive symptoms on ill-health retirement (IHR). METHODS:Data were collected from the Korean Longitudinal Study of Ageing which conducted biennially from 2006 to 2014. IHR were defined as those who retired due to their health problems. The short-form Center for Epidemiological Studies-Depression scale served as outcome measure for definition of depressive symptoms. Hazard ratios of IHR were estimated by Cox regression. RESULTS:We observed that depressive symptoms significantly increased risk of IHR during 8-year follow-up period. Compared with those without depressive symptoms, depressed worker had 1.27-fold elevated risk for IHR. Subgroup analysis showed that the association between depressive symptoms and IHR is greater in the elders, women, and lower income group than the others. CONCLUSION:Depressive symptoms independently predicted IHR. Moreover, age, sex, and socioeconomic status modified these effects.
