This study uses a randomized controlled trial of a school-based anemia reduction program in rural China to examine how increased school emphasis on health promotion affects academic performance. Although education and health promotion are complementary functions of schools, they do compete for finite school resources. We compare the effects of a traditional program that provided only information about anemia and subsidies to an otherwise identical program that included performance incentives for school principals based on school-level anemia prevalence. By the end of the trial, exam scores among students who were anemic at baseline improved under both versions of the program, but scores among students in the incentive group who were healthy at baseline fell relative to healthy students in the control group. Results suggest that performance incentives to improve student health increase the impact of school-based programs on student health outcomes, but may also lead to reallocation of school resources.

In this paper we report the results of a randomized controlled trial designed to measure the impact of a parental training program on the nutritional status of primary school students in rural Shaanxi Province, in Northwest China. Using hemoglobin (Hb) levels as the outcome variable, we first measure the overall impact of a nutritional training program, then measure the impact separately by gender. We use both descriptive and multivariate analyses.

The results for the descriptive and econometric results were robust and consistent with the literature. Overall, we find no impact on students’ Hb levels when we trained their parents about undernutrition and anemia. In both the descriptive and multivariate results, there was no difference in the change of Hb levels between control and treatment students. Parents in the treatment group did learn more about anemia than parents in the control group, but this increased knowledge did not lead to sharp changes in behavior, in general. We did find, however, that there was a measurable impact of parental training on the Hb levels of female students. In both the descriptive and econometric results we found that the Hb levels of female students rose more than that of male students, and that this difference was statistically significant. We conjecture that the parents of female students may have recognized from the training that they were not providing their daughters with sufficient nutrition. Our data show that parents in the treatment group responded by increasing the daily provision of meat, fish, eggs and beans, relative to parents of girls in the control group.

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.

Background. Despite growing wealth and a strengthening commitment from the government to provide quality education, a significant share of students across rural China still have inadequate access to micronutrient-rich regular diets. Such poor diets can lead to nutritional problems, such as iron-deficiency anemia, that can adversely affect attention and learning in school.

Objective. The overall goal of this paper is to test whether simple nutritional interventions lower rates of anemia and to assess whether this leads to improved educational performance among students in poor areas of rural China.

Approach: We report on the results of a randomized control trial (RCT) involving over 3600 fourth grade students, mostly aged 9 to 12, from 66 randomly-chosen elementary schools in 8 of the poorest counties in Shaanxi Province in China’s poor northwest region. The design called for random assignment of schools to one of three groups: two different types of treatment/intervention schools; a non-intervention, control group. The two interventions were designed to improve hemoglobin (Hb) levels, which is a measure of iron deficiency. One intervention provided a daily multivitamin with mineral supplements, including 5 milligrams of iron, for 5 months. The other informed the parents of their child’s anemia status and suggested several courses of action (henceforth, the information treatment).

Findings: Some 38.3 percent of the students had Hb levels of below 120 g/L, the World Health Organization’s cutoff for anemia for children 9 to 12 years old. In the schools that received the multivitamins with mineral supplements, Hb levels rose by more than 2 g/L (about 0.2 standard deviations). The standardized math test scores of the students in the schools that received the multivitamin with mineral supplements also improved significantly. In schools that received the information treatment, only students that lived at home (and not the students that lived in boarding schools and took most of their meals at schools) registered positive improvements in their Hb levels. The reductions in anemia rates and improvements in test scores were greater for students that were anemic at the beginning of the study period. Overall, these results should encourage China’s Ministry of Education (MOE) to begin to widen its view of education (beyond teachers, facilities and curriculum) and provide better nutrition and health care for students.

Objectives: To determine whether China's New Rural Cooperative Medical Scheme (NCMS), which aims to provide health insurance to 800 million rural citizens and to correct distortions in rural primary care, and the individual policy attributes have affected the operation and use of village health clinics.

Design: We performed a difference-in-difference analysis using multivariate linear regressions, controlling for clinic and individual attributes as well as village and year effects.

Setting: 100 villages within 25 rural counties across five Chinese provinces in 2004 and 2007.

Participants: 160 village primary care clinics and 8339 individuals.

Main outcome measures: Clinic outcomes were log average weekly patient flow, log average monthly gross income, log total annual net income, and the proportion of monthly gross income from medicine sales. Individual outcomes were probability of seeking medical care, log annual "out of pocket" health expenditure, and two measures of exposure to financial risk (probability of incurring out of pocket health expenditure above the 90th percentile of spending among the uninsured and probability of financing medical care by borrowing or selling assets).

Results: For village clinics, we found that NCMS was associated with a 26% increase in weekly patient flow and a 29% increase in monthly gross income, but no change in annual net revenue or the proportion of monthly income from drug revenue. For individuals, participation in NCMS was associated with a 5% increase in village clinic use, but no change in overall medical care use. Also, out of pocket medical spending fell by 19% and the two measures of exposure to financial risk declined by 24-63%. These changes occurred across heterogeneous county programmes, even in those with minimal benefit packages.

Conclusions: NCMS provides some financial risk protection for individuals in rural China and has partly corrected distortions in Chinese rural healthcare (reducing the oversupply of specialty services and prescription drugs). However, the scheme may have also shifted uncompensated new responsibilities to village clinics. Given renewed interest among Chinese policy makers in strengthening primary care, the effect of NCMS deserves greater attention.

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.

In this paper, we examine the effect of maternal education on the health of young children by using a large sample of adopted children from China. As adopted children are genetically unrelated to the nurturing parents, the educational effect on them is most likely to be the nurturing effect. We find that the mother's education is an important determinant of the health of adopted children even after we control for income, the number of siblings, health environments, and other socioeconomic variables. Moreover, the effect of the mother's education on the adoptee sample is similar to that on the own birth sample, which suggests that the main effect of the mother's education on child health is in post-natal nurturing. Our work provides new evidence to the general literature that examines the determinants of health and that examines the intergenerational immobility of socioeconomic status.

This paper examines the determinants of child educational attainment. In addition to those examined in previous studies, it is found that maternal childcare is another important determinant of child educational attainment. The results are robust after controlling for endogeneity. The IV estimates show that once childcare time is controlled for, child health does not have an effect on school enrolment age. This finding suggests that omitting the childcare time may have biased the estimated effect of child health on school enrolment in previous studies.
