Abstract

|
The purpose of this study was to identify the latent classes of income status over time and to investigate socioeconomic disparities in trajectories of health and medical expenditure among adults aged 55 to 64 years. The data for this study came from the Korea Health Panel, collected from 2008 to 2013. To verify the purpose of this study, we performed latent class growth analyses and latent growth curve analyses. Trajectories of income status were categorized into four latent classes, low-decreasing, mid-low-decreasing, mid-high-stable, and high-stable groups. There were chronic diseases and subjective health status were different over time depending on latent classes of income status, supporting health disparities. Although there were no socioeconomic differences of trajectories in medical expenditure, individuals in low income status may have disadvantages in medical expenditure with the consideration of their health status. As a result, findings from the study highlight the importance of more sophisticated public policy to reduce the gap of trajectories in health and medical expenditure across socioeconomic status.
