Guided by a life-course perspective, this study investigated the associations between childhood socioeconomic risk factors and depression in old age by identifying subgroups among older adults according to socioeconomic risk factors in childhood. This study used the nationally longitudinal survey data (2006 to 2010) from the Korea Welfare Panel Study (KOWEPS). The sample included 3,779 older adults aged 65 or over. A latent class analysis, one of the person-centered approaches, was adopted to identify latent classes according to childhood socioeconomic risk factors. Then, a multiple regression model was used to analyze the association between the latent classes and depression in old age. This study found three groups of latent classes, which were named as the multiple risk group, the low SES group, and the low risk group. The latent classes by childhood socioeconomic risk factors were associated with current SES variables and depression in old age. Furthermore, the differences between the multiple risk group and the other two groups were still significant with current SES variables controlled. Our findings suggest that childhood socioeconomic risk factors maintain a connection with and have a predictive role in the depression of older adults. The practical implications of these findings were discussed. The strong association between childhood socioeconomic risk factors and depression in old age highlights the importance of early life circumstances on elderly health. Early stage recognition, prevention and supportive measures against childhood socioeconomic disadvantages should be promoted in order to prevent elderly depression and further diminish socioeconomic inequality in health in old age.
