Background. Despite growing wealth and the growing commitment of China’s government to providing quality education, a significant share of children across rural China still have no access to regular sources of iron-rich foods, vitamins and other micronutrients. Such poor diets may not only result in high incidences of nutritional problems, including anemia, good nutrition has been shown to be an effective input into the creation of human capital.

Objective. To increase our understanding of the extent of anemia in poor Shaanxi Province’s primary schools, and identify structural correlates of anemia in this region. Methods. A cross-section survey was conducted. Data were collected from 4000 grade fourth grand students (ages 9 to 11) in 70 primary schools in poor rural areas of Shaanxi province. Structured questionnaires and standard test were used to gather data. Trained nurses carried out the hemoglobin tests (using Hemocue finger prick kits) and anthropomorphic measurements using high quality equipment.

Results. The paper shows that the overall anemia rate is 21.5% (39%) when using a blood hemoglobin cutoff of 115 g/L (120 g/L). We find that those students that are boarding at school and those students that eat lunch away from home are more likely to be anemic. Children with anemia are found to have lower height for age (HAZ) scores and have higher incidences of stunting.

Conclusions. If this part of Shaanxi province is representative of the rest of Shaanxi’s poor rural areas (or all national designed poor counties in China), this means that tens of thousands (or millions) of children in rural Shaanxi (all national designed poor counties in China) may be anemic. Although we were not able to pinpoint the exact determinates and causal effects of anemia, the main implication of this work is that anemia remains a serious health problem for educators and health officials in rural China.

Scott Rozelle is the Helen F. Farnsworth Senior Fellow at the Freeman Spogli Institute for International Studies and Stanford Institute for Economic Policy Research at Stanford University. He received his BS from the University of California, Berkeley, and his MS and PhD from Cornell University. Previously, Rozelle was a professor at the University of California, Davis and an assistant professor in Stanford’s Food Research Institute and department of economics. He currently is a member of several organizations, including the American Economics Association, the International Association for Agricultural Economists, and the Association for Asian Studies. Rozelle also serves on the editorial boards of Economic Development and Cultural Change, Agricultural Economics, the Australian Journal of Agricultural and Resource Economics, and the China Economic Review.

His research focuses almost exclusively on China and is concerned with: agricultural policy, including the supply, demand, and trade in agricultural projects; the emergence and evolution of markets and other economic institutions in the transition process and their implications for equity and efficiency; and the economics of poverty and inequality, with an emphasis on rural education, health and nutrition.

Rozelle's papers have been published in top academic journals, including Science, Nature, American Economic Review, and the Journal of Economic Literature. His book, Invisible China: How the Urban-Rural Divide Threatens China’s Rise, was published in 2020 by The University of Chicago Press. He is fluent in Chinese and has established a research program in which he has close working ties with several Chinese collaborators and policymakers. For the past 20 years, Rozelle has been the chair of the International Advisory Board of the Center for Chinese Agricultural Policy; a co-director of the University of California's Agricultural Issues Center; and a member of Stanford's Walter H. Shorenstein Asia-Pacific Research Center and the Center on Food Security and the Environment.

In recognition of his outstanding achievements, Rozelle has received numerous honors and awards, including the Friendship Award in 2008, the highest award given to a non-Chinese by the Premier; and the National Science and Technology Collaboration Award in 2009 for scientific achievement in collaborative research.

Paragraphs

The main goal of this paper is to document the nature of boarding schools and empirically analyze the difference of nutrition intake and malnutrition status between boarding and non-boarding students in western rural China. By using two data sets about boarding schools and boarding students in Shaanxi Province, a representative province in western rural China, this paper finds that dormitory and student canteen facilities in boarding schools are under-equipped and services are poor quality and far below that needed for student development. Poor services in boarding schools and inadequate nutrition intake may be an important cause of low student height-for-age Z-scores (HAZ), as students eating at school have a much lower HAZ on average than that of non-boarding students. Furthermore, girls and students with more siblings have relatively lower HAZ, while the higher the number of parents a student has and the more educated they are exert a positive influence on child nutritional status in terms of HAZ. Finally, our analysis implies that the effective way to decrease the inequality of health, malnutrition and human capital between urban and rural in the long run is to improve the facilities and services of boarding schools in rural China.
