Health literacy and its influencing factors among the chronically ill
Health literacy (HLIT) is critical for effective self-care in managing chronic illnesses and their outcomes, necessitating targeted interventions. However, existing research is limited in size and scope. This study analysed the status and influencing factors of HLIT among chronically ill individuals in South Korea using a population-based national survey from the Korea Health Panel Survey. From March to July 2021, data were collected from 5652 re…
Health literacy disparities in South Korea
The findings underscore the need for targeted interventions to address the unique challenges faced by populations with low health literacy in a universal health coverage system such as that of South Korea. By identifying those at highest risk for low HLit and targeting policy measures accordingly, healthcare systems can allocate resources more effectively and make health information genuinely accessible for all. In doing so, such strategies can u…
Identifying determinants of unmet healthcare needs in South Korea
Despite a comprehensive national health insurance system in South Korea, achieving universal healthcare access remains challenging. Unmet healthcare needs reflect a confluence of individual-level barriers and broader structural constraints. This study aimed to identify and compare the most influential factors determining unmet healthcare needs using multiple machine learning techniques. This study included 1,489,560 adults aged ≥ 20 who participa…
Unmet healthcare needs and the local extinction index
Background: This study examines the factors affecting unmet healthcare experiences by integrating individual-and community-level extinction indices. Methods: Using spatial autocorrelation and multilevel modeling, the study utilizes data from the Community Health Survey and Statistics Korea for 218 local government regions from 2018 to 2019. Results: The analysis identifies significant clustering, particularly in non-metropolitan regions with a hi…
Regional disparities in health literacy for chronic diseases
Objective: This study compared disparities between community health characteristics and health literacy levels for hypertension and diabetes by combining community-level characteristics, such as the local extinction index and healthcare resources, with individual-level characteristics based on the Andersen healthcare utilization model. Method: Data obtained from the 2017, 2019, and 2021 Community Health Surveys, Korean Statistical Information Ser…
The impact of the expanded health insurance coverage policy on healthcare spending
We observed the policy's intervention effect over time as a decrease in non-payments, on the effectivity of remunerating covered medical services. However, the policy did not work for NHI payments and OOP, suggesting that it failed to control the creation of new non-covered services as noncovered services were converted into covered ones. Thus, it is crucial to discuss the financial spending of health insurance regarding the inclusion of non-cove…
Suicide among Older Adults with Dementia
South Korea recently expanded its coverage rate of long-term care insurance (LTCI) by adding a "dementia special grade" in 2014 to improve care service accessibility and extend health life for older adults with dementia. In this study, we propose a multifaceted policy to reduce the suicide risk among older adults with dementia by evaluating the effectiveness of using the long-term care services (LTCS). A sample of 62,282 older adults was selected…
Self-Rated Health Status Based on the Type of Health Insurance
To investigate the effects of public and private health insurance on self-rated health (SRH) status within the National Health Insurance (NHI) system based on socioeconomic status in South Korea. The data were obtained from 10 867 respondents of the Korea Health Panel (2008-2011). We used hierarchical panel logistic regression models to assess the SRH status. We also added the interaction terms of socioeconomic status and type of health insurance…
Has the long-term care insurance resolved disparities in mortality for older Koreans? examination of service type and income level
The Effect of Usual Source of Care on the Association of Annual Healthcare Expenditure with Patients’ Age and Chronic Disease Duration
Along with rapid population aging, the importance of chronic disease management increases with high growth of national healthcare expenditures, and efficient spending on healthcare is required to reduce unnecessary utilizations. For that reason, this study examined the association of annual healthcare expenditure with age and disease duration of chronic patients. Furthermore, the study investigated the effect of usual source of care (USOC) to sug…
Sitting Time and Obesity or Abdominal Obesity in Older South Koreans
We examined relationships between sitting time and obesity or abdominal obesity according to sex and socioeconomic status in elderly people. We analyzed data from the Korean National Health and Nutrition Examination Survey 2013, and 1565 participants were included in the study. Multivariate logistic regression analysis was used to examine relationships between sitting time and obesity or abdominal obesity according to sex and socioeconomic status…
