Anemia is one of the most prevalent public health problems among infants and iron deficiency anemia has been related to many adverse consequences. The overall goal of this study is to examine the prevalence of anemia among infants in poor rural China and to identify correlates of anemia. In April 2013, we randomly sampled 948 infants aged 6–11 months living in 351 villages across 174 townships in nationally-designated poverty counties in rural areas of southern Shaanxi Province, China. Infants were administered a finger prick blood test for hemoglobin (Hb). Anthropometric measurement and household survey of demographic characteristics and feeding practices were conducted in the survey. We found that 54.3% of 6–11 month old infants in poor rural China are anemic, and 24.3% of sample infants suffer from moderate or severe anemia. We find that children still breastfed over 6 months of age had lower Hb concentrations and higher anemia prevalence than their non-breastfeeding counterparts (p < 0.01), and that children who had ever been formula-fed had significantly higher Hb concentrations and lower anemia prevalence than their non-formula-fed counterparts (p < 0.01). The results suggest the importance of iron supplementation or home fortification while breastfeeding.

Junior high dropout rates are up to 25% in poor, rural areas of China. Although existing studies have examined how factors such as high tuition and opportunity costs contribute to dropout, fewer studies have explored the relationship between dropout rates and mental health in rural China. The overall goal of this study is to examine the relationship between dropout and mental health problems in rural Chinese junior high schools. Correlational analysis was conducted among 4,840 students across 38 junior high schools in rural China. Ordinary least squares (OLS) regressions were used to determine the types of students most at risk for mental health problems and whether mental health problems are correlated with dropout behavior. Our measure for mental health is based on the Children’s Manifest Anxiety Scale. Mental health problems are widespread in the sample of rural children, with 74% of students at risk for mental health problems. The student and family characteristics that correlate with dropout (poverty and low achievement) also correlate with mental health problems. More importantly, even after controlling for these background characteristics, mental health problems remain correlated with dropout rates. Mental health problems, especially among low-achieving poor students, may be contributing to the high dropout rates in rural China today. This finding suggests that interventions focusing on mental health in rural areas may also help reduce dropout.

Empirical evidence suggests that the prevalence of soil-transmitted helminth (STH) infections in remote and poor rural areas is still high among children, the most vulnerable to infection. There is concern that STH infections may detrimentally affect children’s healthy development, including their cognitive ability, nutritional status, and school performance. Medical studies have not yet identified the exact nature of the impact STH infections have on children. The objective of this study is to examine the relationship between STH infections and developmental outcomes in 2,180 school-aged children in seven nationally-designated poverty counties in rural China. We conducted a large-scale survey in Guizhou province in southwest China in May, 2013. Overall, 42 percent of elementary school-aged children were infected with one or more of the three types of STH—Ascarislumbricoides (ascaris), Trichuris trichuria (whipworm) and the hookworms Ancylostoma duodenaleor Necator americanus. After controlling for socioeconomic status, we observed that children infected with one or more STHs have worse cognitive ability, worse nutritional status, and worse school performance than their uninfected peers.

Research increasingly indicates the importance of the nutritional programming that occurs in the first 2–3 years of life. Quality nutrition during this brief window has been shown to have large and significant effects on health and development throughout childhood and even into adulthood. Despite the widespread understanding of this critical window, and the long-term consequences of leaving nutritional deficiencies unaddressed, little is known about the status of infant nutrition in rural China, or about the relationship between infant nutrition and cognitive development in rural China.

We found that 48.8% of sample infants were anaemic, 3.7% were stunted, 1.2% were underweight and 1.6% were wasted. Approximately 20.0% of the sample infants were significantly delayed in their cognitive development, while just over 32.3% of the sample infants were significantly delayed in their psychomotor development. After controlling for potential confounders, infants with lower haemoglobin counts were significantly more likely to be delayed in both their cognitive (p<0.01) and psychomotor development (p<0.01).

Over the past decade, China has implemented reforms designed to expand access to health care in rural areas. Little objective evidence exists, however, on the quality of that care. This paper reports results from a standardized patient study designed to assess the quality of care delivered by village clinicians in rural China. To measure quality, we recruited individuals from the local community to serve as undercover patients and trained them to present consistent symptoms of two common illnesses (dysentery and angina). Based on 82 covert interactions between the standardized patients and local clinicians, we find that the quality of care is low as measured by adherence to clinical checklists and the rates of correct diagnoses and treatments. Further analysis suggests that quality is most strongly correlated with provider qualifications. Our results highlight the need for policy action to address the low quality of care delivered by grassroots providers.

Despite their recent deterioration, village clinics have historically been an important source of health care for the poor and elderly in rural China. In this paper, we examine the current role of village clinics, the patients who use them and some of the services they provide. We focus specifically on the role of village clinics in meeting the health-care needs of the rural poor and elderly. We find that although clinics are continuing to decline financially, they remain a source of care for the rural elderly and poor. We estimate that the elderly are 10–15 percent more likely than young individuals to seek care at a clinic. We show that clinics provide many unique services to support the rural elderly (and the elderly poor), such asin-home patient care, the option for patients to pay on credit, and free and discounted services.

Despite increasing institutional and financial support, certain public health issues are still neglected by the Chinese Government. The present paper examines the soil-transmitted helminth (STH) infection and reinfection rates by conducting a survey on 1724 children in Guizhou Province, China. Our results indicate that 37.5 percent of children had been infected with one or more of the three types of tested STH. However, only 50.4 percent of children reported having taken deworming medicine during the 18-month period before the survey. Of those who reported being dewormed, 34.6 percent tested positive for STH infections. Poverty and number of siblings are significantly and positively correlated with infection and reinfection, and parental education is significantly and negatively correlated with infection and reinfection. Given the ineffectiveness of treatment in these areas to date, for anthelminthic campaigns to actually succeed, China must pay more attention to locallevel incentives to improve children’s health.

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 health, attention and cognitive ability. The overall goal of this paper is to assess the impact of multiple micronutrient supplementation on anemia and anxiety among students in poor areas of rural China. We report on the results of a randomized control trial (RCT) involving over 2700 fourth grade students, mostly aged 9 to 12, from 54 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 two groups. One group received a daily multivitamin with mineral supplements, including 5 milligrams of iron, for 5 months while the other group was a non-intervention, control group. Anemia was defined as < 120 g/L. We found that 42.4 percent of students were anemic at baseline In the schools that received the multivitamins with mineral supplements, Hb levels rose by more than 1.7 g/L over the control schools. The test for anxiety showed that students that received the multivitamin with mineral supplements also improved significantly. Overall, these results should encourage further research on the interaction between nutrition and mental health in a development context.

There is little evidence showing whether health information transmitted via text messages can change health and educational outcomes. We conducted a randomized field experiment involving 900 primary students in rural China to study whether a health education campaign conducted via text message could affect caregiver knowledge or student outcomes. When caregivers received both weekly health messages and monthly quiz questions (testing retention of the information conveyed in the weekly messages), caregiver knowledge improved and students experienced gains in both health and academic performance. When caregivers received weekly health messages only, there was no impact on caregiver knowledge or student outcomes.

We describe the degree to which household income is negatively associated with the prevalence of different types of disability (i.e. medical impairments) in China using data from the 2006 China National Sample Survey of Disabled Persons. We then calculate the extra costs of disability across different types of households and show how these costs differ by the type and severity of disability in both urban and rural areas. We finally use nationally-representative panel data on persons with disabilities from 2007 to 2009 to examine the degree to which social security measures are reaching persons with different types and severity of disabilities in both urban and rural areas. We conclude that while social assistance and insurance for households with disabilities is increasing rapidly over time, it is still not enough to offset the income differential between households with and without disabled persons, especially when accounting for the extra costs of living associated with disability.
