Effectiveness of Provider Incentives for Anaemia Reduction in Rural China: A Cluster Randomised Trial

Objectives To test the impact of provider performance pay for anaemia reduction in rural China. Design A cluster randomised trial of information, subsidies, and incentives for school principals to reduce anaemia among their students. Enumerators and study participants were not informed of study arm assignment. Setting 72 randomly selected rural primary schools across northwest China. Participants 3553 fourth and fifth grade students aged 9-11 years. All fourth and fifth grade students in sample schools participated in the study. Interventions Sample schools were randomly assigned to a control group, with no intervention, or one of three treatment arms: (a) an information arm, in which principals received information about anaemia; (b) a subsidy arm, in which principals received information and unconditional subsidies; and (c) an incentive arm, in which principals received information, subsidies, and financial incentives for reducing anaemia among students. Twenty seven schools were assigned to the control arm (1816 students at baseline, 1623 at end point), 15 were assigned to the information arm (659 students at baseline, 596 at end point), 15 to the subsidy arm (726 students at baseline, 667 at end point), and 15 to the incentive arm (743 students at baseline, 667 at end point). Main outcome measures Student haemoglobin concentrations. Results 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. Conclusions Financial incentives for health improvement were modestly effective. Understanding interactions with other motives and pre-existing incentives is critical.

Nutrition and Educational Performance in Rural China’s Elementary Schools: Results of a Randomized Control Trial in Shaanxi Province

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. The overall goal of this article 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. To meet this goal, we report on the results of a randomized control trial involving over 3,600 fourth-grade students, mostly aged 9–12, from 66 randomly chosen elementary schools in eight 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 and a nonintervention, 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). We found that 38.3% of the students had Hb levels below 120 grams per liter (g/L), the World Health Organization’s cutoff for anemia for children 9–12 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 who lived at home (and not the students who 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 who were anemic at the beginning of the study period. Overall, these results should encourage China’s Ministry of Education to begin to widen its view of education (beyond teachers, facilities, and curriculum) and to provide better nutrition and health care for students.

Soil-Transmitted Helminth Infections and Correlated Risk Factors in Preschool and School-Aged Children in Rural Southwest China

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.

Nutritional Deficiencies, the Absence of Information and Caregiver Shortcomings: A Qualitative Analysis of Infant Feeding Practices in Rural China

Background and Objectives Development during the first two years of life is critical and has a lasting impact on a child’s health. Poor infant and child nutrition can lead to deficiencies in essential micronutrients, which may cause a weakened immune system and lasting effects on childrens growth and development. Recent studies in rural Shaanxi Province found an anemia prevalence of 54.3% among rural children aged six to twelve months. While new large-scale, quantitative research has begun to catalogue the extent of child malnutrition and anemia, no effort has yet been made to look more closely at the potential reasons for rural children’s nutritional deficiencies through qualitative analysis. This study aims to elucidate some of the fundamental causes of poor complementary feeding practices that may lead to anemia among children in rural Shaanxi Province, China. Methodology We interviewed sixty caregivers participating in a large survey on child health and nutrition. We conducted three waves of interviews with children’s primary caregivers in seventeen rural villages within four nationally-designated poverty counties in the southern part of Shaanxi Province. Results The qualitative analysis reveals that poor complementary feeding practices are common across our sample. Information gathered from our interviews suggests that complementary feeding practices are impeded by two constraints: absence of understanding topics related to infant health and nutrition under caregivers, as well as inadequate sources of information on these topics. Poverty does not appear to constrain child feeding practices. Conclusion Our results uncover lack of proper knowledge on infant and child nutrition among rural caregivers in China. This situation causes them to fail incorporating micronutrient rich foods in their childrens diet. Age-appropriate complementary feeding can stimulate children’s physical and cognitive development, but in its absence it leads to iron-deficiency anemia. We suggest that steps be taken to educate caregivers to improve complementary feeding of their infants and children.

The Effect of Early Commitment of Financial Aid on Matriculation to Senior High School Among Poor Junior High Students in Rural China

Students from poor, rural areas of China receive less secondary schooling than their urban peers in part because of high direct and opportunity costs. This study uses a randomized controlled trial to estimate the effectiveness of providing early commitment for financial aid (ECFA) in mitigating secondary schooling costs among poor ninth graders (eight months before their graduation). We find that the likelihood of attending senior high school increases by 9.7 percentage points among ECFA recipients. However, ECFA does not measurably increase student academic performance, reduce dropout, or increase self-esteem.

The Education Gap of China’s Migrant Children and Rural Counterparts

Abstract Rural residents in China today face at least two key decisions: a) where to live and work; and b) where to send their children to school. In this paper we study the second decision: should a rural parent send their child to a public rural school or have him or her attend a private migrant school in the city. While there is an existing literature on the impact of this decision on student academic performance, one of the main shortcomings of current studies is that the data that are used to analyse this issue are not fully comparable. To fill the gap, we collected data on the educational performance of both migrant students who were born in and come from specific source communities (prefecture) in rural China and students who are in rural public schools in the same source communities. Specifically, the dataset facilitates our effort to measure and identity the academic gap between the students in private migrant schools in Shanghai and Suzhou and those in the public rural schools in Anhui. We also seek to identify different sources of the gap, including selection effects and observable school quality effects. According to the results of the analysis, there is a large gap. Students in public rural schools outperform students in private migrant schools by more than one standard deviation (SD). We found that selection effects only account for a small part of this gap. Both school facility effects and teacher effects explain the achievement gap of the students from the two types of schools, although these effects occur in opposite directions.

Passive parenting and its Association with Early Child Development

ABSTRACT This study aims to investigate the developmental status of rural Chinese children, the extent of interactive parenting they receive, and the relation between the two. A sample of 448 six to eighteen-month-old children and their caregivers were randomly selected from two rural counties in Hebei and Yunnan provinces. According the third edition of the Bayley Scales of Infant and Toddler Development, 48.7% of sample children exhibited cognitive delays, 40.6% language delays, and 35% social-emotional delays. According to responses from caregivers, parenting in rural China is largely passive, lacking in interactive practices like storytelling, singing, and playing. Children-with-siblings, left-behind children, and children with less-educated mothers were even less likely to receive interactive practices. Children of caregivers who did engage in best parenting practices showed better cognitive, language, and social-emotional development; however, the public health system provides no platform for learning about optimal parenting.

Effect of Deworming on Indices of Health, Cognition, and Education among Schoolchildren in Rural China: A Cluster-Randomized Controlled Trial

AbstractSoil-transmitted helminths (STHs) infect over one billion people worldwide. There is concern that chronic infection with STHs among school-aged children may detrimentally affect their development, including their health, cognition, and education. However, two recent Cochrane reviews examining the impact of deworming drugs for STH on nutrition, hemoglobin, and school performance found that randomized controlled trials (RCTs) in the literature provide an insufficient evidence base to draw reliable conclusions. This study uses a cluster-RCT to add to existing evidence by assessing the impact of a deworming intervention on nutrition, cognition, and school performance among schoolchildren in rural China. The intervention, implemented by local health practitioners in a setting with a baseline infection prevalence of 41.9% (95% confidence interval [CI] = 39.8%, 43.9%) and infection intensity of 599.5 eggs per gram of feces among positive-tested schoolchildren (95% CI = 473.2, 725.8), consisted of distributing a 400-mg dose of albendazole accompanied with educational training about STH infection, treatment, and prevention. The intervention was conducted twice over the course of the study-at baseline in May 2013 and later in November 2013. We found that the deworming intervention reduced both infection prevalence and infection intensity, but these declines in infection were not accompanied by an impact on outcomes of nutrition, cognition, or school performance. Our interpretation is that the impact of deworming was attenuated by the light infection intensity in our sample population. Evidence from future RCTs is needed to assess the effect of deworming on key outcomes in areas with moderate and severe worm infections.

Are Children with Siblings Really More Vulnerable Than Only Children in Health, Cognition and Non-cognitive Outcomes? Evidence from a Multi-province Dataset in China

The general goal of the present study is to analyze whether children with siblings lag behind their only-child counterparts in terms of health and nutrition, cognition and educational performance, and non-cognitive outcomes. We draw on a dataset containing 25 871 observations constructed from three school-level surveys spanning four provinces in China. The analysis compares children with siblings and only children aged 9 to 14 years old in terms of eight different health, cognitive and non-cognitive indicators. We find that with the exception of the anemia rate, health outcomes of children with siblings are statistically indistinguishable from those of only children. In terms of cognition, children with siblings performed better than only children. Moreover, outcomes of children with siblings are statistically indistinguishable from those of only children in terms of the non-cognitive outcomes provided by measures of anxiety. According to our results, the same general findings are true regardless of whether the difference between children with and without siblings is disaggregated by gender.

To Board or Not to Board: Evidence from Nutrition, Health and Education Outcomes of Students in Rural China

The debate over whether boarding school is beneficial for students still exists in both developing and developed countries. In rural China, as a result of a national school merger program that began in 2001, the number of boarding students has increased dramatically. Little research has been done, however, to measure how boarding status may be correlated with nutrition, health and educational outcomes. In this paper, we compare the outcomes of boarding to those of non-boarding students using a large, aggregate dataset that includes 59 rural counties across five provinces in China. We find that for all outcomes boarding students perform worse than non-boarding students. Despite these differences, the absolute levels of all outcomes are low for both boarding and non-boarding students, indicating a need for new policies that will target all rural students regardless of their boarding status.
