The purpose of this study is to describe the health status and health services utilization of older Koreans and examine the factors that are associated with effective health services utilization. The findings are based on data from the first wave of the Korean Longitudinal Study of Ageing (KLoSA) conducted by the Korea Labor Institute. It is anticipated the findings of this study will be of value in identifying the subgroup differences in utilization. The Aday-Andersen model is used to identify the subgroup differences in utilization. Aday and Andersen introduce “equitable distribution”, which is important for addressing the problem of access to care [15,16]. It would be useful to utilize the model to interpret the results of this study.
