Abstract
|
|
|
This study aimed to explore the trajectories of the change and the longitudinal correlations in self-rated health(SRH), unmet healthcare needs(UN) and outpatient service uses(OU), and the factors affecting these trajectories in medical aids(MA) recipients. For this, an analysis was conducted applying the Latent Growth Model for the 168 people who continued to receive MA from 2011 to 2018 in the Korea Health Panel. According to the analysis, the SRH declined, and the rate of experience of UN and the number of OU increased over time. Those with poor initial SRH had a higher rate of experience of UN and a more number of OU.
The initial value and the rate of change between the experience of UN and the number of OU were found to have no statistical correlation. The number of OU increased faster in those with good initial SRH, and the decline of SRH was found to be faster in those who experienced initial UN. The longer the duration of receiving MA is, the better the initial SRH and the slower the rate of increase in the number of OU. This study is significant in that it is the first longitudinal study of health dynamics of MA recipients. We expect this result can be used for seeking policy alternatives to improve health of MA recipients.
