Objectives: The purpose of this study was to investigate effective predictive factors of the persistence of unmet dental care needs. Methods: Data were obtained from the Korea Health Panel studies of 2011 and 2015, and 4,406 subjects, aged 18 years or older, were included in this study. Of these subjects, those who persistently experienced unmet dental care needs over the three-year period were identified. Panel logistic regression analyses were conducted to identify socio-demographic and health-related factors associated with the persistence of unmet dental care needs in two groups, those aged between 18-64 years and over 65 years. Results: Approximately 12% of subjects showed a persistence in unmet dental care needs. Marital status, education level, household income, type of health insurance, and self-rated health status all significantly correlated with the persistence of unmet dental care needs in both age groups. Conclusions: Efforts should be made to identify factors related to the persistence of unmet dental care needs in order to improve patient accessibility to dental care services.

Objectives: Parental socioeconomic status (SES) exerts a substantial influence on children's health. The purpose of this study was to examine factors determining children's private health insurance (PHI) enrolment and children's healthcare utilization according to PHI coverage. Methods: Korea Health Panel data from 2011 (n=3085) was used to explore the factors determining PHI enrolment in children younger than 15 years of age. A logit model contained health status and SES variables for both children and parents. A fixed effects model identified factors influencing healthcare utilization in children aged 10 years or younger, using 2008 to 2011 panel data (n=9084). Results: The factors determining children's PHI enrolment included children's age and sex and parents' educational status, employment status, and household income quintile. PHI exerted a significant effect on outpatient cost, inpatient cost, and number of admissions. Number of outpatient visits and total length of stay were not affected by PHI status. The interaction between PHI and age group increased outpatient cost significantly. Conclusions: Children's PHI enrolment was influenced by parents' SES, while healthcare utilization was affected by health and disability status. Therefore, the results of this study suggest disparities in healthcare utilization according to PHI enrollment.

The purpose of this study was to examine dental care utilization and expenditures among children aged 0 to 19 years using Korea Health Panel Survey (KHPS) data in 2008 - 2013. Weighted estimates were nationally representative and statistical significances were analysed by $x^2$ test or adjusted Wald test using STATA 13 software. While dental care utilization increased steadily among children from 2008 through 2013, less than one-third the children received dental care in 2013. Compared with 2008, the proportion of restorative care, oral surgery, preventive care decreased and the proportion of orthodontic care, prosthetic care increased. While the proportion of amalgam markedly decreased, the proportion of resin increased. This study highlight socioeconomic disparities in dental utilization and expenditures among children. Especially the findings provide a baseline assessment for examining trends on dental care for children in the future.

This paper tests existence of precautionary saving motive under health uncertainty, using household level panel data from Korea. For this purpose, this paper considers a dynamic health capital model with health uncertainty and derives testable equations for changes in consumption and medical expenditures. Under this framework, households who face future health uncertainty will exhibit precautionary behavior by depressing consumption or increasing investment in health. To test this hypothesis, the paper uses the conditional variance of health as the direct measure of health uncertainty, obtained by estimating a multinomial logit model. Empirical results using the Korean Household Panel Study (KHPS, 1993 - 1997) suggest that Korean elderly households follow the precautionary behavior to insure against future health risk.

Purpose: This study investigated the factors associated with suicidal ideation in the Korean Echo Generation using 2012 Korea Health Panel Data. Methods: The 2012 Korea Health Panel Data were collected from February 2012 to July 2012 and included 2,303 people who responded to a question asking whether they had experienced suicidal ideation. The data were analyzed by chi-square and multiple logistic regression test using SPSS 22.0. Results: The rate of suicidal ideation was 4.2% in the Echo Generation. Factors associated with suicidal ideation in the Echo Generation revealed that the following variables increased the rate of suicidal ideation: sex(odd ratio: 2.39, CI: 1.39-4.09), education(odd ratio: 1.95, CI: 1.08-3.52), depression(odd ratio: 12.06, CI: 6.92-21.03), frustrating experience(odd ratio: 2.52, CI: 1.22-5.20), anxiety about the future(odd ratio: 14.58, CI: 3.20-66.41), self-rated health status(odd ratio: 2.39, CI: 1.39-4.09 and odd ratio: 6.41, CI 2.87-14.33). Conclusion: This study provides a preliminary examination of the factors associated with suicidal ideation in the Echo Generation. A more careful examination may be warranted.

Objective : In order to understand the scale of medicinal expenditure in the Korean medicine, an analysis has been made of Korean National Health Account and statistic archives used to estimate the Korean National Health Account and also of such archives as are contributory to learn the scale of total health expenditures in the Korean medicine. Method : From the Korean National Health Account archives, an analysis has been made of National health insurance statistic annual reports, National health insurance non-payment items, Korean Economic Census (The Service Industy Survey), and Korea Health Panel data. Moreover, in order to know the sales of overall Korean medicine clinics, relevant data have been utilized and cited from investigations into National tax statistics, Korean medicine medical institutions and Korean medicines used, and current states of medicinal herbs and Korean medicine industry. Results : It is found that the average scale of each section of the medical expenditures archives in the Korean medicine in 2012 was KRW 3.5638 billion and that the average medical expenditures in the Korean medicine derived from Total Health Expenditure, The Service Industy Survey, National tax statistic, and Korean medicine industry are approximately KRW 3.3901, 3.4796, 3.7218 and 3.9634 billion. And the average expenditures derived from National health insurance patients and Korea Health Panel data are 2.5162 and 2.2292 billion won and those from the users and consumers of Korean medicines and herbs are 5.6,461 billion won. In order to verify the appropriateness of estimated medical expenditures in the Korean medicine included in the archives, an analysis has been made of uninsured costs which come from the aggregate sales amount surveyed minus health insurance treatment expenditures and it is found that the ratio of insured costs against total health expenditures in 2006 was 50.67% and 41.92% in 2012 and that the ratio based on National tax statistics and The Service Industy Survey was 52.19% and 49.28% in 2006 and 50.54% and 50.64% in 2012 and that the ratio of uninsured costs against Korean medicines and herbs and Korean medicine industry was 37.5% and 58.27% in 2013. Conclusion : It calls for the improvement of the accuracy of an investigation into Total Health Expenditure which comprise the actual conditions of health insurance and Korea Health Panel, the development of statistic schemes for understanding and classifying medical expenditures of all the Korean medicine medicinal institutions like medicinal clinics, and enhanced methods for independent panels to comprehensively collect and analyze the number of sampled Korean medicine medical institutions.

Background: This study aims to analyze the effects of air pollutants, such as particular matter, to the number of outpatient visits for allergic rhinitis in eup, myeon, and dong administrative boundaries. Methods: Dependent variable was the number of outpatient visits for allergic rhinitis per 10,000 people by region. Independent variables were air pollutants such as PM₁₀, PM_2.5, SO₂, O₃, CO₂, NO₂, and temperature that estimated by using Kriging analysis in all eup, myeon, and dong boundaries. Panel analysis was applied for the analysis to prove the relation between outpatient visits and the concentration of air pollutants. Results: Analysis results showed that particular matter concentration varied by regions and season. Panel analysis showed that outpatient visits for allergic rhinitis had positive relationships with PM₁₀, PM_2.5, SO₂, O₃, and CO₂ in all panel models. Conclusion: Regional variation of particular matter concentration should be considered in establishing regional policies for allergic rhinitis.

Korea Health Panel Survey (KHPS) has been conducted to provide nationally representative estimates of health care use and expenditures for non-institutionalized population in Korea since 2008. The aim of this study was to present estimates from KHPS on dental utilization and expenditures from 2008 to 2011. While weighted estimates were presented for each year from 2008 to 2011, the focus of this study was on the 2011 estimates and changes in dental utilization and expenditures between 2008 and 2011. Weighted estimates were obtained using population weights and statistical significances were analysed by independent t-test or ANOVA test using SPSS version 20 for Windows. In 2011, 21.1% of Korean population obtained outpatient dental services from dentists. From 2008 to 2011, the percent of people with a dental visit in each year increased slightly. In 2011, the mean number of dental visits was 4.46. While the mean number of dental visits remained stable by 2010, it increased slightly in 2011. The total annual dental expense in 2011 for people with a visit was about 460,000 Korean Won and 10% higher in 2008. In summary, this study results highlight low rates of dental utilization and high dental expenses in Korean population.
