Reading, Writing and Raisinets: Are School Finances Contributing to Children's Obesity?

The proportion of adolescents in the United States who are obese has nearly tripled over the last two decades. At the same time, schools, often citing financial pressures, have given students greater access to "junk" foods, using proceeds from the sales to fund school programs. We examine whether schools under financial pressure are more likely to adopt potentially unhealthful food policies. We find that a 10 percentage point increase in the probability of access to junk food leads to about a one percent increase in students' body mass index (BMI). However, this average effect is entirely driven by adolescents who have an overweight parent, for whom the effect of such food policies is much larger (2.2%). This suggests that those adolescents who have a genetic or family susceptibility to obesity are most affected by the school food environment. A rough calculation suggests that the increase in availability of junk foods in schools can account for about one-fifth of the increase in average BMI among adolescents over the last decade.

Maternal employment and overweight children

This paper seeks to determine whether a causal relationship exists between maternal employment and childhood overweight. We use matched mother/child data from the National Longitudinal Survey of Youth and employ econometric techniques to control for observable and unobservable differences across individuals and families that may influence both children's weight and their mothers' work patterns. Our results indicate that a child is more likely to be overweight if his/her mother worked more hours per week over the child's life. Analyses by subgroups show that it is higher socioeconomic status mothers whose work intensity is particularly deleterious for their children's overweight status.Employment (Economic theory) ; Overweight children

Maternal Employment and Overweight Children

This paper investigates whether children are more or less likely to be overweight if their mothers work. The prevalence of both overweight children and working mothers has risen dramatically over the past few decades, although these parallel trends may be coincidental. The goal of this paper is to help determine whether a causal relationship exists between maternal employment and childhood overweight. To accomplish this, we mainly utilize matched mother/child data from the National Longitudinal Survey of Youth and employ three main econometric techniques, probit models, sibling difference models, and instrumental variables models in this analysis. Our results indicate that a child is more likely to be overweight if his/her mother worked more intensively (in the form of greater hours per week) over the child's life. This effect is particularly evident for children of white mothers, of mothers with more education, and of mothers with a high income level. Applying our estimates to the trend towards greater maternal employment indicates that the increased hours worked per week among mothers between 1975 and 1999 led to about a 0.4 to 0.7 percentage point increase in overweight children, which represents a relatively small share of the overall increase.

Childhood Disadvantage and Obesity: Is Nurture Trumping Nature?

Obesity has been one of the fastest growing health concerns among children, particularly among disadvantaged children. For children overall, obesity rates have tripled from 5% in the early 1970s to about 15% by the early 2000s. For disadvantaged children, obesity rates are closer to 20%. In this paper, we first examine the impact of various measures of disadvantage on children's weight outcomes over the past 30 years, finding that the disadvantaged have gained weight faster. Over the same period, adult obesity rates have grown, and we expect parental obesity to be closely tied to children's obesity, for reasons of both nature and nurture. Thus, examining changes in the parent-child correlation in BMI should give us some insight into the ways in which the environment that parents and children share has affected children's body mass, or into how the interaction of genes and environment has changed. We find that the elasticity between mothers' and children's BMI has increased since the 1970s, suggesting that shared genetic-environmental factors have become more important in determining obesity. Despite the faster weight gain for the disadvantaged, there appears to be no clear difference for by disadvantaged group in either the parent-child elasticity or in identifiable environmental factors. On average, the increases in parents' BMI between the early 1970s and the early 2000s can explain about 37 percent of the increase in children's BMI. Although common environmental/genetic factors play a larger role now than in earlier time periods, child specific environments such as schools and day care play a potentially important role in determining children's health status.

Economic perspectives on childhood obesity

Obesity rates in the U.S. have skyrocketed in the last 30 years. Among adults, obesity rates more than doubled from the early 1970s to the late 1990s. Children obesity rates nearly tripled over the same period. This article discusses why obesity is of interest from an economic perspective. It them examines changes in children's lives, particularly the increase in maternal employment, that may have contributed to increases in children's weight.Overweight children

The US safety net caught some poor households during the Great Recession, but many just above the poverty line slipped through the cracks.

The Great Recession saw large increases in unemployment and greater housing insecurity for many, which in turn led to increased take up of social safety net programs such as food stamps. In new research, Patricia M. Anderson, Kristin F. Butcher and Diane Whitmore Schanzenbach find that while households that are below the poverty line were largely shielded from additional hardships during the Great Recession, those with incomes just above it slipped through the cracks of the safety net, and experienced additional hardships

Adequate (or Adipose?) Yearly Progress: Assessing the Effect of "No Child Left Behind" on Children's Obesity

This paper investigates how accountability pressures under No Child Left Behind (NCLB) may affect children’s rate of overweight. Schools facing increased pressures to produce academic outcomes may reallocate their efforts in ways that have unintended consequences for children’s health. For example, schools may cut back on recess and physical education in favor of increasing time on tested subjects. To examine the impact of school accountability programs, we create a unique panel data set of schools in Arkansas that allows us to test the impact of NCLB rules on students’ weight outcomes. Our main approach is to consider schools to be facing increased pressures if they are on the margin of passing – that is, if any subgroup at the school has a passing rate that is close to the AYP passing threshold, where we define close as being 5 percentage points above or below the threshold. We find evidence of small effects of accountability pressures on the percent of students at a school that are overweight. A follow-up survey of school principals points to reductions in physical activity and worsening of the food environment as potential mechanisms.
