Health and Medicine

FSI’s researchers assess health and medicine through the lenses of economics, nutrition and politics. They’re studying and influencing public health policies of local and national governments and the roles that corporations and nongovernmental organizations play in providing health care around the world. Scholars look at how governance affects citizens’ health, how children’s health care access affects the aging process and how to improve children’s health in Guatemala and rural China. They want to know what it will take for people to cook more safely and breathe more easily in developing countries.

FSI professors investigate how lifestyles affect health. What good does gardening do for older Americans? What are the benefits of eating organic food or growing genetically modified rice in China? They study cost-effectiveness by examining programs like those aimed at preventing the spread of tuberculosis in Russian prisons. Policies that impact obesity and undernutrition are examined; as are the public health implications of limiting salt in processed foods and the role of smoking among men who work in Chinese factories. FSI health research looks at sweeping domestic policies like the Affordable Care Act and the role of foreign aid in affecting the price of HIV drugs in Africa.

Abstract

 

Introduction

Like many other countries, China had a fragmented health insurance system; in China's case, there were two separate schemes covering rural and urban residents. This study focused on the policy implications of integrating the schemes, particularly on the psychological effects.

 

Methods

The study used four waves of data from the China Health and Retirement Longitudinal Study (CHARLS) collected in 2011, 2013, 2015, and 2018, adopting a time-varying DID approach to capture the effect of integration on depressive symptoms among rural residents.

 

Results

The average CES-D score of rural adults decreased by 0.424, and the likelihood of depressive symptoms decreased by 3.5% after the implementation of the urban–rural health insurance integration policy. The positive effects may be due to the reduced cost-sharing rates as well as improvements in health satisfaction, social interactions, and physical activity. The integration reform had a limited impact on improving the mental health of those with the lowest economic status, the worst health status, and those aged 40–49 or over 70.

 

Discussion

This health insurance integration helped to improve mental health among rural adults. There are several policy implications:

  1. The positive policy effects suggest that further improvements could result from the Chinese government expanding coverage of the rural program, moving up to provincial- or national-level pooling, and encouraging more to enroll.
  2. More targeted solutions to decrease inequity should be considered, like focusing on rural adults over 70 with low income/low wealth
  3. Reimbursement rates under the rural insurance program remain low, so increased funding for the program is warranted.
  4. Strengthening healthcare facilities and resources in rural areas is an important next step

 

Highlights
 

  • CES-D scores for rural adults decreased by 0.424
  • Likelihood of depressive symptoms decreased by 3.5%
  • Benefits began appearing two years before integration, perhaps indicating positive expectations

Alzheimer’s disease and related dementias (ADRD) are putting a significant strain on families and healthcare systems worldwide, and with increasing life expectancies, they pose an escalating global challenge. As one of the world’s fastest aging economies, South Korea’s efforts to address the burden of care for people living with ADRD offer valuable lessons for other nations grappling with the social and economic pressures of the demographic transition.

new comprehensive review of Korea’s programs and policies to promote healthy aging and diagnose, treat, and care for people living with ADRD sheds light on progress and ongoing challenges. Published in the May 2025 issue of Alzheimer's & Dementia: The Journal of the Alzheimer's Association, the review offers insights from Korea’s strategies that resonate far beyond its borders.

The co-authors – Stanford health economist Karen Eggleston, the director of APARC’s Asia Health Policy Program (AHPP), and Daejung Kim, an associate research fellow at the Korea Institute for Health and Social Affairs – focus on recent policies supporting “aging in place” for independent seniors and palliative care for those needing greater support.

Eggleston and Kim used a mixed-methods review of dementia care in Korea over the past 25 years, combining a critical analysis of peer-reviewed social science and health policy studies in both English and Korean, quantitative analysis of Korean statistical agency data compared with other OECD countries, and interviews with local policymakers and welfare administrators in a region with a high proportion of elderly population.



Social and Policy Pressures in a Rapidly Aging Economy


Korea is aging fast, and the prevalence of ADRD among older adults is expected to surge, as is the projected social and economic toll of dementia care. Demographic and economic projections suggest that the annual cost of ADRD in Korea would increase from 0.9 percent to almost four percent of GDP from 2019 to 2050.

“Korea’s demographic transition, like its economic development, has been compressed into just a few generations,” Eggleston and Kim explain. “As a result, its triumph of longevity and current extra-low fertility engender social strains and policy pressures to address the burgeoning needs for long-term services and support – including prevention of ADRD, investing in early detection, and providing appropriate care for people with ADRD, which often involves addressing the broader social issue of financial support for older adults and detecting cognitive decline in those still engaged in the labor force.”

A Foundation for Dementia Care Service Delivery


Korea has taken decisive steps to build a comprehensive system for dementia care, leveraging its national health insurance and long-term care insurance (LTCI). This dual insurance framework aims to reduce unnecessary hospitalizations and shift social care away from medical settings.

Research shows that “the adoption of LTCI in 2008 helped to address regional disparities by providing nationwide risk pooling for long-term care services,” but the system still faces hurdles. Within Korea’s private-dominated service delivery system, the public-private balance varies significantly across different services, coordination between healthcare and long-term care services remains fragmented, and there is a need for better integration of community-based support.

Furthermore, “social insurance is no panacea for mitigating disparities and securing financial support for the most vulnerable citizens, such as people with ADRD and their families,” Eggleston and Kim note. Out-of-pocket payments for medical care still constitute a substantial portion of Korean household consumption.

The economic and social costs of dementia will impose an even greater burden if population aging further slows GDP growth in Korea beyond current projections (for example, because of labor shortages and lower productivity growth in specific sectors of the economy).
Eggleston & Kim

Livelihood and Workforce Challenges


In light of Korea’s limited sources of financial support for its older citizens, the country has relatively high labor force participation, especially among older men. This high level of employment of older Koreans may bode ill in an economy where many of the “senior employment” positions – primarily low-paying roles in the service sector – are not age-friendly.

Giving elderly persons a reason to get up in the morning has its benefits, Eggleston and Kim note, but having them perform service jobs is not a sustainable way to support livelihoods and healthy aging. “How decision-making by cognitively impaired individuals affects health and financial well-being can be considered the defining feature of the economics perspective on ADRD and its social impacts,” the co-authors say.

The growing demand for professional dementia care strains Korea’s caregiving workforce in other ways. Amid the shortage and aging of caregivers, much of dementia care falls on unpaid family members, often women in their 50s, lowering their rates of labor force participation in prime age. The burden on these informal caregivers is profound.

The authors note that “Korea needs more strategies to recruit, retain, and empower a knowledgeable and resilient caregiving workforce.”

Prevention and Early Diagnosis: A Mixed Picture


Early detection is critical for planning care and support for people with ADRD, and Korea is taking steps to design programs and incentives for healthy aging habits and early ADRD detection. These efforts, however, require stronger staffing and funding to offer more personalized and coordinated care.

Another set of challenges stems from the underuse of existing long-term services and support programs and the need to diversify them. Currently, providers have weak incentives to offer palliative care, while families and patients often struggle to choose comfort care over ongoing medical treatments.

Policymakers must also expand the target group of beneficiaries and diversify long-term services and support for daily life, including promoting a reduction in risk factors associated with dementia, such as low educational attainment, smoking, physical inactivity, uncontrolled chronic diseases, and depression. Eggleston and Kim call for developing “additional care service types such as hospital companion and nutrition support services” and integrating new technologies as part of a diversified, long-term aging-in-place care system.

Better care support for daily life would involve the development of additional care service types, such as hospital companion services and nutrition support services. Aging-in-place also relies on effective housing support.
Eggleston & Kim

Expanding Care Options 


The demographic transition has been accompanied by shifting social norms regarding responsibilities and caregiving, meaning significantly fewer Koreans believe care for older parents is the sole responsibility of family members. Accordingly, Korean policies aim to strengthen home- and community-based services (HCBS). Yet, the country’s share of at-home care recipients remains lower than in many peer economies.

“Making the vision of quality HCBS a reality involves multiple dimensions of financing and service delivery, tailored to local and individual circumstances while supporting equitable access nationally for those in need,” write Eggleston and Kim.

Institutional care in residential facilities remains a necessity for frail older people with ADRD and multiple comorbidities. While the supply of such service providers has greatly improved and long-term care insurance coverage has enhanced their affordability for families, wide disparities in quality of care for those in residential facilities persist. Meanwhile, hospice and palliative care remain largely an underdeveloped care option for people with ADRD in Korea.

Lessons for Aging Economies


South Korea’s dementia care journey illustrates the complex balancing act of addressing the multiple dimensions of a rapid demographic transition. The country’s efforts to promote healthy aging and diagnose, treat, and care for people with ADRD offer valuable insights for other economies that must prepare to provide long-term support for their aging populations.

One major imperative in Korea and elsewhere is ensuring that dementia care policies and programs are based on robust evidence. “To utilize limited resources most effectively, it will be critical to design and collect policy-relevant evidence about what works for people with ADRD and their care partners,” Eggleston and Kim write.

In Rapidly Aging South Korea, the Economy Is Slow in Creating “Age-Friendly” Jobs

Despite the nation’s rapidly aging demographics, South Korea's economy has not adapted as well as the United States, a new study finds. The researchers, including Stanford health economist and director of the Asia Health Policy Program at APARC Karen Eggleston, show that age-friendly jobs attract a broad range of workers and that structural barriers in the labor market influence which groups can access these roles.

Abstract

 

 

Cover of Vol. 21, Issue 5, of "Alzheimer's & Dementia: The Journal of the Alzheimer's Association"

Introduction

As one of the most rapidly aging societies globally, Korea's efforts to mitigate the social burden of Alzheimer's disease and related dementias (ADRD) may provide valuable insights.

 

Methods

We conducted a mixed-methods review of studies and policies related to dementia care in Korea over the past 25 years, including quantitative analysis of administrative and comparative data.

 

Results

Estimates suggest a high social burden from ADRD, with annual costs increasing from 0.9% to 3.8% of gross domestic product between 2019 and 2050. Pilot programs for integrated community care and hospice palliative care reveal the advantages of innovating from a foundation of national health insurance and long-term care insurance, as well as the continuing challenges of appropriately designing programs and incentives for early detection, integrated care, and late-life palliative care.

 

Discussion

A rigorous analysis of programs addressing uneven quality and a study of the impact of integrated care models for home- and community-based services would be valuable.

 

Highlights
 

  • A mixed-method review highlights the challenges of rapid aging in Korea.
  • Universal health and long-term care systems support innovation for dementia care.
  • Dementia costs are projected to increase from 0.9% to 3.8% of gross domestic product in 2019–2050.
  • Pilots of integrated community care and hospice palliative care show promise.
  • Rigorous analysis of programs to address uneven quality would be valuable.

Alberto Diaz Cayeros seminar

The conquest of the Americas produced a radical transformation of pre-colonial Empires and City States. Europeans established a new institution, the Encomienda, which “entrusted” indigenous communities to individual conquistadores, which resulted in the dismemberment and fragmentation of prior political authority. Using a simple model of temporal horizons and rent extraction, I explore demographic change and epidemic disease after the conquest of Mexico. Data is drawn from the legal and census records of Tepetlaoztoc, a polity within the Acolhua Kingdom, one of the three parts of the Aztec Empire. This rich dataset allows for the reconstruction of demographic change and the calculation of individual and household level epidemiological models. The analysis suggests that the dramatic demographic decline of the 16th century in Mexico, rather than an inevitable result of exposure to unknown pathogens or epidemic diseases beyond human control, was a consequence of colonial rent extraction and the loss of political autonomy and sovereignty.

Mai Nguyen joins the Walter H. Shorenstein Asia-Pacific Research Center (APARC) as Asia Health Policy Postdoctoral Fellow for the 2024-2025 academic year. She holds a PhD in health services and health policy from Queensland University of Technology (QUT), Australia, and a Master of Science from Heller School for Social Policy and Management, Brandeis University.

Her doctoral research focused on how the expanding private healthcare sector can be managed more effectively to better supplement public health services to achieve universal health coverage in Vietnam. The study analyzed large and complex national health datasets from two consecutive Household Living Standard Surveys, clinical hospital data at national levels and in-depth interviews with key stakeholders of Vietnam's health system to investigate consumers' choice for private and public health care services in Vietnam. Her research findings have implications for policy change in terms of harnessing and regulating private health services in Vietnam and other Asia-Pacific countries, especially low and middle-income countries.

Dr. Nguyen has worked as a senior health specialist at Vietnam Ministry of Health. Her research interest stems from her professional experience in health policy and program management, including health policy and management, health services, private healthcare and health equity. Her works have been published in many Q1-international journals such as BMC Public Health, BMC Health Services Research, Human Resources for Health and International Journal of Health Policy and Management.

At APARC, Dr. Nguyen will extend her research on the roles of private healthcare to supplement the public health sector to address the growing burden of chronic diseases and conditions in Vietnam.

Asia Health Policy Postdoctoral Fellow, 2024-2025
Jinseok Kim_0.jpg

Jinseok Kim joins the Walter H. Shorenstein Asia-Pacific Research Center (APARC) as Asia Health Policy Postdoctoral Fellow for the 2024-2025 academic year. He recently obtained his Ph.D. in economics at the Technology, Economics, Management and Policy Program of Seoul National University. He holds a Master of Science degree in Environmental Technology from Imperial College of London as well as Bachelor of Arts and Sciences from University College London. His research interest mainly lies in behavioral economics, demand forecasting, and policy analysis in the fields of technology diffusion, energy and environment.

His thesis (tentative title), “Quantum-like Approach to Random Utility Maximization Framework: Application to Discrete Choice Modelling,” applies the concepts of quantum mechanics to provide a reinterpretation of human decision-making process under the random utility maximization framework, which is found to derive an expanded model that accounts for the randomness of human choice as well as the effect of self-uncertainty at the individual-level. Through choice analysis under this new quantum-like theoretical framework, this study endeavors to make both theoretical and empirical contributions to choice modeling. 

During his time in Shorenstein Asia-Pacific Research Center, he hopes to expand his area of expertise by taking upon a research project that aims to analyze the impact of population aging to innovation diffusion and technology consumption. Through this project, he hopes to make real contributions to future preparations and policy structuring for imminent changes in society.
