Timing is Everything: The Impact of School Lunch Length on Children's Body Weight

The large number of overweight children in the United States has prompted school administrators and policy makers to identify practices in schools that contribute to unhealthy weight outcomes for children and develop strategies to prevent further increases. Advocates for school nutrition reform have suggested that it is important for children to have an adequate amount of time to eat meals in school in order to maintain a healthy weight. This article examines whether the length of time children are given to eat lunch in school has an impact on their weight. I find evidence that an increase in lunch length reduces the probability a child is overweight, and this finding is robust across various econometric specifications, including a two‐sample instrumental variable model and difference‐in‐differences model that account for the potential endogeneity of lunch length.     

Does wealth matter? An assessment of China's rural-urban migration on the education of left-behind children

This paper decomposes the impact of parental migration on the education of children left behind. In particular, we examine whether children are enrolled in school on a timely basis according to their age when their parents are away. We found both theoretical and empirical evidence to support that parental migration generates a strong positive impact on timely enrollment if a child is from a less wealthy background. However, the effect decreases with family wealth, and reverses after reaching a threshold; we find this point using family house size as our proxy and the turning point occurs at a moderate size of approximately 148 square meters. In addition, we find a compensating effect that migrants tend to spend more on a child's education investment to offset for the loss of parental time care. Lastly, we found the overall impact of parental migration is negative on the timely enrollment of child. Thus, with the important heterogeneities attributed to wealth, our results suggest that the left behind children of more affluent parents may be pushed into worse human capital outcomes; given the rapid development of China, it may be the case that the current cohort of left behind children is less likely to be enrolled in school than earlier cohorts.     

Finding the Benefits: Estimating the Impact of The South African Child Support Grant

This paper estimates the impact of the South African Child Support Grant (CSG) on child health, nutrition and education. Data from the 2008 South African National Income Dynamics Study are used to estimate the impact of the CSG on six different outcomes measuring child well‐being. We find a positive treatment effect of the CSG on children's height‐for‐age, progress through the school system, as well as household expenditure on food items using a continuous treatment estimator developed by Hirano and Imbens. Robustness analysis using the inverse probability weighting approach by Flores and Mitnik is also implemented. Although these estimates provide some evidence of a positive impact resulting from the CSG, they are not conclusive in showing that the cash transfers are spent mainly on improving the lives of beneficiary children, as the treatment effects are quite small.     

Socioeconomic Determinants of Child Health: Empirical Evidence from Indonesia

This paper characterizes the socioeconomic determinants of child health using height‐for‐age z‐score (HAZ), a long‐run measure of chronic nutritional deficiency. We construct a panel data that follows children between ages 3 and 59 months in 1993 through the 1997 and 2000 waves of the Indonesian Family Life Survey. We use this data to identify the various child‐level, household‐level and community‐level factors that affect children's health. Our findings indicate that household income has a large and statistically significant role in explaining improvements in HAZ. We also find a strong positive association between parental height and HAZ. At the community level, we find that provision of electricity and the availability of paved roads are positively associated with improvements in HAZ. Finally, in comparison to community‐level factors, household‐level characteristics play a large role in explaining the variation in HAZ. These findings suggest that policies that address the demand‐side constraints have greater potential to improve children's health outcomes in the future.     

The Contribution of the School Environment to the Overall Food Environment Experienced by Children

Despite the important role of schools in the food environment faced by children, most research examining access to healthy food has focused on the retail sector. We create a database of school menus and the nutritional information about each item on the menu from nearly all school districts in the United States to examine the influence of the school‐based food environment on the nutritional choices of children. Using the National Household Food Acquisition and Purchase Survey (FoodAPS), we find that, holding constant the neighborhood retail food environment, exposure to healthier meals at school increases the healthfulness of foods acquired by children throughout the day.     

Is There any Threshold in the Relationship Between Mother's Education and Child Health? Evidence from Nigeria

The literature on mother's education and child health casually observes some nonlinearities and also a threshold in the relationship. Even though this nonlinearity or threshold has significant bearing on policy matters such as quality of education, any rigorous attempt to address this issue is missing in the literature. With height for age z‐score as a proxy for long‐run child health capital, regression results reveal that there are significant effects of mother's education on child health if mothers do not continue past primary school. Rather, poor quality of education at the primary level, especially literacy, is argued to have given rise to this threshold. It indicates that greater public investment in improving quality of education at the primary level is essential for maximizing the nonmarket outcomes of girls’ education in developing countries.     

Solution or isolation: Is boarding school a good solution for left-behind children in rural China?

In recent decades, rural China has experienced a rapid increase in boarding school enrollment rates and in the population of left-behind children (LBC) (i.e., rural children whose parents migrate to urban areas for work). LBC tend to be worse off in numerous dimensions. At 61 million, China has the world's largest population of LBC. As it provides a different residential environment, boarding school can potentially exacerbate or mitigate the negative effects of parental migration. Using nationally representative data on Chinese families, we estimate the impact of parental migration and boarding school on child outcomes in cognition and physical and mental health. We find that while boarding school has no effect on LBC physical and mental health, it substantially improves performance on achievement tests for both LBC and non-LBC. Policies aimed at improving boarding school conditions in China, may improve not only cognitive outcomes, but also child physical and mental well-being.     

The reach and impact of Child Support Grants: evidence from KwaZulu-Natal

This paper examines the reach and impact of the South African Child Support Grant, using longitudinal data collected through the Africa Centre for Health and Population Studies. The grant is being taken up for a third of all age-eligible resident children, and appears to be reaching those children living in the poorer households of the demographic surveillance area (DSA). Children who received the grant are significantly more likely to be enrolled in school in the years following grant receipt than are equally poor children of the same age. However, older brothers and sisters of grant recipients, when they were observed at younger ages, were less likely than other children to be enrolled in school – perhaps reflecting the greater poverty in grant-receiving households. Thus the grant appears to help overcome the impact of poverty on school enrolment.     

THE IMPACT OF THE INDONESIAN FINANCIAL CRISIS ON CHILDREN: AN ANALYSIS USING THE 100 VILLAGES DATA

This paper examines the impact of the Asian financial crisis on children in Indonesia. Specifically, data from four rounds of the 100 Villages Survey are used to examine changes in school attendance rates, child labour force participation and health status. The paper also examines ways in which households are coping with the crisis. The findings provide little evidence that the crisis has had a dramatic negative impact on children. School attendance dropped slightly after the onset of the crisis but has since rebounded to higher than pre-crisis levels. Fewer children are now working, although the older children who are working and not attending school seem to be working longer hours. Comparisons of child health status indicators over time are complicated by changes in the questionnaire but appear to show a relatively stable pattern of child health.     

Parental income and child health in Japan

Previous studies have consistently found evidence of an income gradient in health among children in various countries, and studies in Anglo-Saxon countries have found that this gradient increases with child age. Using nationally representative individual-level data, I examine the association between child health and parental income in Japan. Japan has a child poverty rate that is similar to the rate of many countries that have been studied previously, but Japan outperforms those countries on most health indicators. I find that an income gradient exists in child health in Japan, but that it is limited to specific health measures and symptoms, and that it is weaker overall in that respect than the gradient found in other countries or among Japanese adults. Moreover, I find no evidence that the gradient increases with child age. The fact that children in low-income families have relatively modest and non-accumulating health disadvantages may contribute to the overall health of the Japanese population. Nevertheless, there is a statistically significant negative association between parental income and the incidences of asthma, hearing problems, and dental symptoms in children, implying that future efforts to improve the health of underprivileged children should focus on the prevention and control of these diseases.     

Determinants of Indonesian rural secondary school enrolment: gender,neighbourhood and school characteristics

In recent years the school enrolment rates of children aged 13–15 and 16–18 years have increased sharply in Indonesia, not only in urban but also in rural areas. Using various data sets spanning the years from 1993 to 2007, this paper investigates changes in factors associated with the enrolment of secondary school aged children in rural areas. It sheds light on the roles of gender and of neighbourhood and school characteristics, which have rarely been examined in the Indonesian context. The study finds that the disappearance of a gender gap in secondary enrolments between 1993 and 2007 contributed significantly to the rise in the overall enrolment rate. The findings also show that children living in wealthier communities and communities with a high proportion of enrolled children are more likely to attend school. Finally, various school characteristics are shown not to be strongly or consistently correlated with school enrolment.     

Large-scale school meal programs and student health: Evidence from rural China

Reducing urban-rural gaps in child health is one of the most difficult challenges faced by many countries. This paper evaluates the impact of a large-scale school meal program in rural China on the health and nutritional status of students aged 6–16 in compulsory education. We use data from the China Health and Nutrition Survey corresponding to four pre-treatment years (2004, 2006, 2009, and 2011) and one post-treatment year (2015) and find that program participation is, on average, associated with a higher child height-for-age. The impacts are larger among students in a better health condition but small or not significant among the most disadvantaged. We do not observe heterogeneous effects across several individual and household characteristics. We also find positive but not significant effects on Body Mass Index-for-age and weight-for-age. The results suggest that NIP partially improved students' health over the first years of implementation, but more support is needed to achieve broader impacts that effectively reach all vulnerable students.     

Impact of International Remittances on Schooling in the Philippines: Does the Relationship to the Household Head Matter?

We study the impact of international remittances on schooling in the Philippines, taking into account the school‐age individual's relationship to the household head. This consideration is important because employment opportunities abroad may be taken at the expense of the quality of child rearing. Our estimation results indicate that there are, indeed, significant negative guardian effects on school attendance and education expenditures when children with overseas parents are looked after by a relative other than a parent or grandparent. However, these negative effects tend to be outweighed by the positive impact of remittance flows from overseas.     

Women’s Empowerment and Child Malnutrition: The Case of Mozambique

Using data from the 2011 Demographic and Health Survey in Mozambique this paper checks whether women empowerment has an impact on the nutritional status of children. We evaluate the degree of empowerment of women via multidimensional approaches, making a distinction between five domains: decision making, use of violence by husband/partner, attitude of the woman towards this use of violence, available information, material resources. Each domain includes several questions reflecting different aspects of empowerment. For each domain of empowerment, three different methods of aggregation are used: correspondence analysis, the so‐called Alkire and Foster methodology and the “fuzzy sets” approach. The impact of women empowerment on the nutritional status of children is analyzed via the MIMIC approach. No clear‐cut conclusion concerning the possible impact of women’s empowerment on the nutritional status of children could be drawn. But, ceteris paribus, the material wealth of the household, the educational level of the mother and her BMI are positively correlated with the nutritional status of children which is also higher when the child is female. Finally, there are important differences in the nutritional status of children between the various regions of Mozambique and this nutritional status is in most regions lower in rural areas.     

Child day‐labourers in agriculture: evidence from farm accounts, 1740–18501

While child labour has always been an important part of the industrial revolution story, there is little quantitative evidence about the number of child workers in the 1740–1850 period. This article estimates trends in the percentage of the agricultural day‐labouring workforce that were children. By using the wage level to identify child workers, it is possible to estimate child labour for a large sample of English farms. It is found that girls were rarely employed as day‐labourers, while boys were employed about as frequently as women. The percentage of boys in the day‐labour workforce increased until the 1820s and then declined.     

The Effect of Household Socioeconomic Status on the Demand for Child Health Care Services

The health of the child is an important factor for proper childhood development. Unfortunately, efforts to improve child health in many countries have not yielded the desired results as many children do not receive appropriate health care, hence contributing to high child mortality and morbidity from avoidable causes. To address this problem, it is important that we understand the factors that drive the demand for child health care services. This study, employing the binary and multinomial logistic regression models, examines the effect of household socioeconomic status on the demand for child health care in Ghana, Kenya and Zambia using data from the 2014 Demographic and Health Surveys. The results indicate that the likelihood of seeking appropriate health care for the child is higher when both parents make decisions. The findings further indicate that the odds of seeking treatment for the child falls with the birth order and age of the child, but increases with household wealth, insurance status and proximity to the health facility. Working women are more likely to demand child health care than their counterparts who are unemployed. Our results, therefore, suggest that improving child health will need the participation of both parents in the household on such decisions. Besides, there is the need to educate parents on the importance of seeking appropriate care for all the children born irrespective of the birth order and age of the child. There should also be deliberate efforts to improve the economic lot of households to enhance their purchasing power and encourage them to participate in health insurance schemes to enable effective utilization of health care services for the child in the efforts to improve child health.     

Parental Education and child Nutrition in Indonesia

This study uses 1989 Susenas household data to examine the impact of parental education on pre-school children's nutritional status, as measured by weight-for-age Z-scores. Reduced form regressions are estimated separately for boys and girls in rural and urban areas; explanatory variables include mother's and household head's education; per capita household expenditure; and aspects of the household sanitary environment. The analysis controls for influence of unobserved heterogeneity at village level, e.g. differences in prices and medical service provision. The estimates show a significant effect of parental schooling on child health status, varying between urban and rural areas, and by child gender and age. Mothers with secondary education typically have healthier boys than those with less schooling, while this effect is seen for girls only if the mother has more than secondary education. Maternal schooling significantly affects 2–5 year olds' health, but has little direct effect on that of younger children.     

Parental Behavior and the Value of Children's Health: A Health Production Approach

Data on individual children and on sibling pairs are used to examine how family resource allocations affect children's health and to estimate willingness to pay for reduced acute illness in children. Results highlight the importance of accounting for the endogeneity of child health and suggest that children with greater stocks of health capital whose parents invest in preventive and remedial medical care experience fewer days of illness. Estimated willingness to pay to avoid one day of illness-induced school loss is about $100 to $150, a range broadly consistent with limited prior evidence but substantially more than unit values applied in recent policy analyses. All else equal, willingness to pay is higher among single parents and for uninsured children, and the estimated income elasticity is only 0.14. Implied aggregate benefits of reductions in children's sick time associated with air pollution control may be substantial.     

Parental Education and Child Health: Evidence from China*

This paper examines the effect of parental, household and community character‐istics on the health of children in China. We find that birth order, death of elder siblings, use of prenatal care and alcohol consumption by the mother when pregnant have statistically significant effects on the health of children. Although parental education does not have a significant direct effect on child health, it does affect mothers’ behavior during pregnancy and inflfluences the use of health inputs, indirectly impacting the health of children. The research findings have important implications for both family planning programs and broader social policies in China.     

Children's growth in an adaptive framework: explaining the growth patterns of American slaves and other historical populations

This article presents a new adaptive framework for understanding children's growth in the past. Drawing upon the recent work on adaptive responses in relation to growth, it presents prenatal and postnatal adaptive mechanisms that affect the growth patterns of children. The most novel adaptive response to the historical literature is the prenatal predictive adaptive response where the metabolism and growth trajectory of a child is programmed to match predicted conditions later in life. Having discussed the framework in detail, a reinterpretation of the growth pattern of American slaves is then suggested. It seems likely that a mismatch between relatively good conditions in utero and absolutely appalling conditions in infancy and early childhood led slave children to become extremely stunted by the age of three or four. However, after this age, slave children experienced catch‐up growth because their immune systems had become more developed and because their diet improved tremendously and hookworm exposure was reduced. Thus, it seems that American slave children may have experienced substantial catch‐up growth because they were prenatally programmed for a higher metabolism and growth trajectory. The article concludes by setting out some stylized facts about children's growth in the past and pointing toward areas of future research.
