Objective : This study aimed to analyze the association between lifestyle and medical expenses of older adults with mental illness using claims data. Methods : We conducted secondary data analysis using the older adult cohort database provided by the Korea National Health Insurance Service. The lifestyle and medical expense variables were extracted from the cohort database. We used a generalized linear model to examine the association between lifestyle and medical expenses. Results : In total, 32,853 records were extracted. The results showed that smokers had medical expenses (estimate = -218,255, p = .037). As the number of days of walking increased, medical expenses significantly decreased (estimate = -58,843, p < .0001). Furthermore, as the number of days of drinking decreased, medical expenses increased (estimate = 692,289, p < .0001). Conclusion : This study analyzed the estimates of medical expenses according to lifestyle among older adults with mental illness. Smoking and exercise were negatively associated with medical expenses. These results suggest the importance of a healthy lifestyle for older adults with mental illness. In addition, this study can be used as clinical evidence for lifestyle management programs to improve physical and mental health.

This study analyzed the size and influence factors of annual average health expenditure according to job type. Using data from the Korea Health Panel (2012), the final analysis was conducted on adults aged 20 years or older, excluding the missing data. Data analysis was done by logistic regression analysis to analyze the factors affecting medical expenditure. As a result of the study, Model 1 showed higher expenditure on medical expenses by skilled workers in agriculture and forestry fishery than those in simple labor. Model 2 was analyzed as having a positive effect on the increase of medical expenditure by the simple worker in the sales of the occupation, statistically significant by sex, marriage, income level and chronic disease. Therefore, it would be necessary to establish social security and health care & welfare policies, in order to grasp the disease with a high frequency rate according to occupation status and activate the physical examination and preventive actions.

Background: In recent years, studies have shown conflicting results regarding the benefits of dietary supplements in reducing healthcare expenditures. This study aimed to address this inconsistency by examining the association between supplement consumption and health expenditures using nationally representative data from the Korea Health Panel Survey (2019-2020). Methods: A 1:1 matched case-control dataset was established using propensity score matching technique based on supplement consumption. Then, total annual healthcare expenditures were compared between the two groups. In addition, a multivariate regression analysis (Proc Surveyreg) was performed to determine the association between the supplement consumption and medical costs. Results: The supplement user group spent about 1.72 million Korean won, while the non-user group spent about 1.43 million Korean won on medical services (p=0.0186). The results of multivariate regression showed that the costs were approximately 26.15% higher in the user group than in the non-user group (p=0.0004). Conclusion: Contrary to the previous studies that have shown the benefits of supplement use in reducing healthcare costs, this study showed that those who consistently consumed supplements spent more on medical services. This can be interpreted in the same context as previous studies suggesting that dietary supplement intake is a healthy behavior for managing one's health. However, we caution against drawing firm conclusions due to data limitations. Further analysis using patient-level epidemiologic data is needed.

현재 흡연으로 인한 COPD(만성폐쇄성폐질환)의 국내 의료비 부담이 심각한 것으로 드러났다. COPD 의료비 증가로 인한 경제적 부담감도 심각하지만, 천식 등으로 오인되는 COPD 환자 등 잠재환자의 증가와 더불어 COPD로 인한 사회경제적 손실도 더욱 커질 전망이다.

This study tried to find the relationship between household income level and medical expense to household income ratio. For data analysis, it used 2010 and 2011 yearly data beta version of Korea Health Panel, co-managed by Korea Institute for Health and Social Affairs and National Health Insurance Corporation. To find out how the effect of independent variable changes in 2010 and 2011, the interaction effect between year and independent variable was examined, and separating the factors that showed interaction effect into each year, linear regression analysis was conducted using generalized estimating equations method. As a result of reviewing the factors that were related to medical expense to household income ratio among the people who used medical services, it was found that the higher the household income level, the lower the medical expense. It indicates that policy measures are needed to lessen the medical burden of low-income families.

In this study, only 2,877 men, 2,614 men (44.6%), and 143 women (2.3%) were selected as the subjects who were over 18 years old in response to the health consciousness of the Korean medical panel data in 2012. Emergency of smokers through medical use and medical expenditure data by smoking. The social costs were estimated through medical expenses according to the number of hospitalization and outpatient medical use. The social cost was calculated by summing the social expenditure on health care costs, insurer (corporation) costs, copayment, non - salary, and productivity costs by adopting the social perspective established by the health economist Rice (1968). The rate of annual emergency medical use by smoking status is 7.5% for smokers per 100 people, 9.8 times for use, and 809,003 won for social expenses. The annual rate of hospitalization per 100,000 population by smoking status was 9.6% for smokers per 100 population, 9 times for use, The social cost is 706,870 won.

This study aims to examine the trend in household catastrophic medical expenditure according to the healthcare coverage types and its associated factors based on the raw data of the Korean Health Panel over the years 2008 to 2011. Correspondence analysis was used to investigate the trend in the incidence rates of annual catastrophic medical expenditure and generalized estimating equation to examine the factors influencing the incidence of catastrophic medical expenditure. The annual mean incidence rates of household catastrophic medical expenditure were 25.1%, 15.4%, 10.1%, 5.4% and 3.2% in the threshold levels of 10%, 15%, 20%, 30%, and 40% respectively. The incidence rate of household catastrophic medical expenditure was higher when the total annual household income was lower, the education level of the householder was lower, the healthcare coverage type was National Health Insurance, the householder had disability, the age of the householder was older, the number of household members was smaller, the subjective health status of household members was lower, and the prevalence rate of the chronic disease of the household was higher(p<0.05). Therefore, a policy for vulnerable households with older or patient members of chronic diseases should be established.
