Demographic change is fast becoming one of the most globally significant trends of the 21st century. Declining fertility rates and rising life expectancy -- two of the patterns triggering demographic change -- will cause vast socioeconomic strains, especially in the Asia-Pacific region, which has some of the world's most populous countries. Stanford health researcher Karen Eggleston says comparison and cross-collaboration are needed to induce creative solutions.

In an interview with the Office of International Affairs, Eggleston discusses her research approaches and partnerships in the study of healthcare systems and health policy in the Asia-Pacific region. She leads a multiyear research initative that examines comparative policy responses to demographic change in East Asia. Eggleston says the goal is to help move global health policy to a place where everyone has an "equal opportunity for a healthier and longer life."

Analyzing demographic change in China, Japan and South Korea is the focus of the book Aging Asia, an outcome of a conference between the Walter H. Shorenstein Asia-Pacific Research Center and the Stanford Center on Longevity.

Eggleston also coedited a special issue of the Journal of the Economics of Ageing with David Bloom, a professor at Harvard University, looking at a range of economic issues related to population change in China and India.

“I am the first child of my parents. I have a small brother at home. If the first child were a son, my parents might be happy ... but I am a daughter. I complete all the household tasks, go to school, again do the household activities in the evening … my parents do not give value or recognition to me.”

Stanford Assistant Professor of Medicine Marcella Alsan often refers to this comment by a 15-year-old girl from Nepal when she talks about how the division of labor among men and women starts at a young age in the developing world.

“Anecdotally, girls must sacrifice their education to help out with domestic tasks, including taking care of children, a job that becomes more onerous if their younger siblings are ill,” said, Alsan, a core faculty member at the Center for Health Policy/Center for Primary Care and Outcomes Research (CHP/PCOR) within the Freeman Spogli Institute of International Studies, and the Department of Medicine.

More than 100 million girls worldwide fail to complete secondary school, despite research that shows a mother’s literacy is the most robust predictor of child survival. So Alsan is analyzing whether medical interventions in children under 5 tend to lead their older sisters back to school.

She is one of two winners of this year’s Rosenkranz Prize for Health Care Research in Developing Countries, awarded by CHP/PCOR to promising young Stanford researchers.

Her Stanford Department of Medicine colleague, Jason Andrews, is the other recipient of the $100,000 prize given to young Stanford researchers to investigate ways to improve access to health care in developing countries.

Andrews is looking at cheap, effective diagnostic tools for infectious diseases, while Alsan is researching how older girls in poorer countries are impacted by the health of their younger siblings.

“My proposed work lays the foundation for a more comprehensive understanding of how illness in households and early child health interventions impact a critical determinant of human development: an older girl’s education,” she said.

Alsan, the only infectious-disease trained economist in the United States, said Stanford is the ideal place to carry out her interdisciplinary global health research.

“I am humbled and honored to receive this prize, since Dr. Rosenkranz has done so much for women’s health worldwide,” she said.

Alsan – an MD with a specialty in infectious disease who has a PhD in economics from Harvard – said she intends to estimate the impact that illnesses in under-5 children have on older girls’ schooling using econometric tools.

She will compile data from more than 100 Demographic and Health Surveys (DHS) covering nearly 4 million children living in low- and middle-income countries.

The surveys ask about episodes of diarrhea, pneumonia and fever in children under 5 and record data on literacy and school enrollment for every child in the household.

Alsan also intends to collaborate with partners in sub-Saharan Africa to study the gendered effect of household illness on time use, using culturally appropriate questionnaires.

Douglas K. Owens, a Stanford professor of medicine and director of CHP/PCOR, called Alsan’s work “groundbreaking.”

“Although training is critical, more importantly, her work to date shows a degree of innovation, creativity and rigor that led us to conclude she was likely to become one of the top investigators in her field worldwide,” he said.

Low-Cost Diagnostic Tools

Andrews, also an assistant professor of medicine, has been working on ways to bring low-cost diagnostic tools to impoverished communities that bear the brunt of disability and death from infectious disease.

“I began working in rural Nepal as an undergraduate student and as a medical student founded a nonprofit organization that provides free medical services in one of the most remote and impoverished parts of the country,” Andrews said. “As I became a primary physician, and then an infectious diseases specialist, one of the consistent and critical challenges I encountered in this setting was routine diagnosis of infectious disease.”

He said those routine diagnostics were typically hindered by lack of electricity, limited laboratory infrastructure and lack of trained lab personnel.

“In my experiences working throughout rural Nepal – and in India, South Africa, Brazil, Peru and Ethiopia – I found these challenges to be common across rural resource-limited settings,” said Andrews, who founded a nonprofit Nyaya Health – recently renamed Possible Health – which provides modern, low-cost healthcare to rural Nepal.

Andrews has been collaborating with engineers to develop an electricity-free, culture-based incubation and identification system for typhoid; low-cost portable microscopes to detect parasitic worm infections; and most recently an easy-to-use molecular diagnostic tool that does not require electricity.

“The motivation for these projects was not to develop fundamentally new diagnostic approaches, but rather to find simple, low-cost means to make established laboratory techniques affordable and accessible,” he said.

“We then perform isothermal amplification heated by a reusable, solar-heated, phase-change material,” Andrews said, adding that the entire process is completed in less than 20 minutes and can be performed by anyone with minimal training.

Andrews will enroll 250 patients with suspected cases of cholera in Nepal, using the new diagnostic tools and adapting as many local supplies as possible.

Andrews also intends to establish and curate a website to gather open-source ideas and evidence on diagnostic techniques for use in the developing world.

“Stanford is one of the world’s greatest hubs for innovation and information sharing as pertains to science and technology and is an ideal home for this venture,” he said.

In the current scientific climate, most National Institutes of Health grants go to established researchers. The Rosenkranz Prize aims to stimulate the work of Stanford’s bright young stars – researchers who have the desire to improve health care in the developing world, but lack the resources.

The award’s namesake, George Rosenkranz, first synthesized cortisone in 1951, and later progestin, the active ingredient in oral birth control pills. He went on to establish the Mexican National Institute for Genomic Medicine, and his family created the Rosenkranz Prize in 2009.

The award embodies Dr. Rosenkranz’s belief that young scientists hold the curiosity and drive necessary to find alternative solutions to longstanding health-care dilemmas.

“As in past years, the competition was extremely tough,” said Grant Miller, a senior fellow at the Freeman Spogli Institute and associate professor of medicine who chaired the prize committee this year.

“It’s exciting to see all of the truly innovative global health research being done by junior scholars at Stanford,” he said. “Both Jason and Marcella really exemplify this – and the legacy of George Rosenkranz.”

Maria Polyakova, an assistant professor of health research and policy at the Stanford School of Medicine, is this year’s recipient of the Ernst-Meyer Prize, which recognizes original research about risk and health insurance economics.

Polyakova, who wrote her thesis, “Regulation of Public Health Insurance,” while working on her Ph.D. in economics at MIT, was given the award by The Geneva Association, an international insurance economics think tank based in Switzerland.

Courbage said the topic not only had considerable academic interest, but also was “an important public policy issue in both the United States and Europe.

“This work makes extremely useful insights about an important area of public policy that has yet to get the attention it needs: the interaction of regulation with important demand and supply-side features of private insurance markets.”

Polyakova said she was honored to receive the award and thanked her thesis committee for their “unbounded support” of her work.

“I am especially grateful to Amy Finkelstein for inspiring my interest in social insurance in general, and health insurance, in particular,” she said. “I hope to continue my work in this area."

A summary of Polyakova’s thesis will be published in the July 2015 issue of The Geneva Association’s Insurance Economics newsletter.

A rapidly aging population poses serious challenges for many countries around the world, particularly in Asia, home to the most populous countries. China and India account for nearly 36% of the world’s population, and are expected to face social and economic complications from demographic change in the next decades.

A special issue of the Journal of the Economics of Ageing explores these trends in a comparative perspective, “The Economic Implications of Population Ageing in China and India” (December 2014), co-edited by David Bloom, a professor at Harvard University’s School of Public Health, and Karen Eggleston, a Center Fellow at the Shorenstein Asia-Pacific Research Center.

“Population ageing represents uncharted waters for China and India,” Bloom and Eggleston write in their coauthored introduction.

The special issue is a collection of 10 articles that examine the economic benefits and potential dilemmas arising from decreased fertility and increased life expectancy, two trends that will impact the development and future trajectories of China and India at the micro- and macroeconomic levels.

Dropping or continued low birth rates imply fewer young people to refresh the labor market. But will this cause the workforce to shrink to an unsustainable level? Demand will increase for health care, long term care, and other social services that support the elderly. What must the government do to ensure adequate access to care?

Empirical data and commentary presented in the special issue seek to inform stakeholders about emerging patterns, and to provide insight on how to best address related policy challenges going forward.

“By adopting responsive behaviors and consultative institutions that address the challenges of population ageing in ways that are appropriate to their unique circumstances, China and India could reap the full economic and social benefits of longer, healthier lives,” they write.

The special issue includes an introduction by Bloom and Eggleston, a feature interview with Richard Suzman, and additional analysis by noted global health experts following each article. The titles and authors of the 10 original research articles are listed below:

China’s State Council has put forth draft legislation that would ban smoking in public spaces, part of the government’s larger advocacy efforts to help curb tobacco use nationwide. Matthew Kohrman, a professor of anthropology at Stanford University, said it’s a step forward but the ban’s long-term success would depend on local enforcement.

Despite popular belief, global cigarette production has tripled worldwide since the 1960s. Leading the surge has been China.

“China has become the world’s cigarette superpower,” said Kohrman, in an interview on National Public Radio’s program, Marketplace.

Moreover, local governments in China have become dependent on tax revenues generated from tobacco sales, thus reinforcing the cigarette’s ubiquity and ease of access.

China has implemented smoking bans in the past, but with varied success. Now rising healthcare costs caused by tobacco-related diseases are creating urgency for new regulations.

“Whether or not these new regulations will be enforced will, in the end, come down to local politics,” he said.

Matthew Kohrman is part of the Asia Health Policy Program at the Shorenstein Asia-Pacific Research Center, and leads the project, Cigarette Citadels, a peer-sourced mapping project that compiles more than 480 cigarette factories globally.
