摘要：The number of overweight youth has more than doubled since the early 1970s. According
to the Center for Disease Control, approximately 13 percent of children and adolescents are
seriously overweight. Obesity among adolescents has been linked with behavioral and
psychological problems, affecting adolescent socialization, self-esteem, and performance in all
facets of life. Using data from the 1997 National Longitudinal Survey of Youth, we employ
ordinary least squares, instrumental variables, and quantile regression models to investigate how
being overweight can impact a youth’s education performance measured as actual creditweighted
grade point average. Overall, we find a negative relationship between being overweight
and GPA. We also find that the negative relationship is more pronounced in urban areas than in
rural areas. The quantile regression estimate indicates that the magnitude of the relationship
between youth’s GPA and being overweight depends on the GPA quantile in question.
