Yunwei is a Postdoctoral Scholar at Stanford University, with a background training in global health economics. Prior to joining Stanford, she earned a PhD in Health Policy and Management (Economics Track) from the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill in 2024. Her research explores innovative solutions for effective delivery of public health interventions in resource-limited settings with rigorous experimental and quasi-experimental designs. Her current research agenda is centered on integrating digital health technologies to develop comprehensive and tailored interventions for children and mothers living in resource-limited settings during crucial developmental stages, aiming for both effectiveness and scalability.

Despite recent reductions in prevalence, China still faces a substantial tuberculosis (TB) burden, with future progress dependent on the ability of rural providers to appropriately detect and refer TB patients for further care. This study (a) provides a baseline assessment of the ability of rural providers to correctly manage presumptive TB cases; (b) measures the gap between provider knowledge and practice and; (c) evaluates how ongoing reforms of China’s health system—characterized by a movement toward “integrated care” and promo- tion of initial contact with grassroots providers—will affect the care of TB patients.

Prof. Stephen Luby studied philosophy and earned a Bachelor of Arts summa cum laude from Creighton University. He then earned his medical degree from the University of Texas Southwestern Medical School at Dallas and completed his residency in internal medicine at the University of Rochester-Strong Memorial Hospital. He studied epidemiology and preventive medicine at the Centers for Disease Control and Prevention.

Prof. Luby's former positions include leading the Epidemiology Unit of the Community Health Sciences Department at the Aga Khan University in Karachi, Pakistan, for five years and working as a Medical Epidemiologist in the Foodborne and Diarrheal Diseases Branch of the U.S. Centers for Disease Control and Prevention (CDC) exploring causes and prevention of diarrheal disease in settings where diarrhea is a leading cause of childhood death.  Immediately prior to joining the Stanford faculty, Prof. Luby served for eight years at the International Centre for Diarrhoeal Diseases Research, Bangladesh (icddr,b), where he directed the Centre for Communicable Diseases. He was also the Country Director for CDC in Bangladesh.

During his over 25 years of public health work in low-income countries, Prof. Luby frequently encountered political and governance difficulties undermining efforts to improve public health. His work within the Center on Democracy, Development, and the Rule of Law (CDDRL) connects him with a community of scholars who provide ideas and approaches to understand and address these critical barriers.

We conducted a survey of 1707 children in 141 impoverished rural areas of Guizhou and Sichuan Provinces in Southwest China. Kato-Katz smear testing of stool samples elucidated the prevalence of ascariasis, trichuriasis and hookworm infections in pre-school and school aged children. Demographic, hygiene, household and anthropometric data were collected to better understand risks for infection in this population. 21.2 percent of pre-school children and 22.9 percent of school aged children were infected with at least one of the three types of STH. In Guizhou, 33.9 percent of pre-school children were infected, as were 40.1 percent of school aged children. In Sichuan, these numbers were 9.7 percent and 6.6 percent, respectively. Number of siblings, maternal education, consumption of uncooked meat, consumption of unboiled water, and livestock ownership all correlated significantly with STH infection. Through decomposition analysis, we determined that these correlates made up 26.7 percent of the difference in STH infection between the two provinces. Multivariate analysis showed that STH infection is associated with significantly lower weight-for-age and height-for-age z-scores; moreover, older children infected with STHs lag further behind on the international growth scales than younger children.

Background: To study how misaligned supply-side incentives impede health programs in developing countries, we tested the impact of performance pay for anemia reduction in rural China. To the best of our knowledge, our study is the first to evaluate performance pay for actual health improvement.

Methods: We conducted a cluster randomised trial of information, subsidies, and incentives for school principals to reduce anemia among fourth and fifth grade students in 72 randomly-selected rural primary schools across northwest China. Our experiment included a control and three treatment arms: (1) an information arm in which principals received education about anemia; (2) a subsidy arm in which principals received information and unconditional subsidies; and (3) an incentive arm in which principals received information, subsidies, and financial incentives for reducing anemia among students. Students, parents, nursing teams, and survey enumerators were blind to arm assignment. Primary outcomes were student hemoglobin concentrations; secondary outcomes were behavioral responses to the interventions.

Findings: Mean student haemoglobin concentration rose by 1.5 g/L (95% CI –1.1 to 4.1) in information schools, 0.8 g/L (–1.8 to 3.3) in subsidy schools, and 2.4 g/L (0 to 4.9) in incentive schools compared with the control group. This increase in haemoglobin corresponded to a reduction in prevalence of anaemia (Hb <115 g/L) of 24% in incentive schools. Interactions with pre-existing incentives for principals to achieve good academic performance led to substantially larger gains in the information and incentive arms: when combined with incentives for good academic performance, associated effects on student haemoglobin concentration were 9.8 g/L (4.1 to 15.5) larger in information schools and 8.6 g/L (2.1 to 15.1) larger in incentive schools.

Interpretation: Financial incentives for health improvement were modestly effective. Understanding interactions with other motives and pre-existing incentives is critical.

As a health and development economist based at the Stanford School of Medicine, Dr. Miller's overarching focus is research and teaching aimed at developing more effective health improvement strategies for developing countries.

His agenda addresses three major interrelated themes: First, what are the major causes of population health improvement around the world and over time? His projects addressing this question are retrospective observational studies that focus both on historical health improvement and the determinants of population health in developing countries today. Second, what are the behavioral underpinnings of the major determinants of population health improvement? Policy relevance and generalizability require knowing not only which factors have contributed most to population health gains, but also why. Third, how can programs and policies use these behavioral insights to improve population health more effectively? The ultimate test of policy relevance is the ability to help formulate new strategies using these insights that are effective.
