This papers adds to the literature on child bodyweight and human capital using data from the Early Childhood Longitudinal Survey Kindergarten Class of 2010–2011. We examine how bodyweight is related to both children's test scores and teacher assessment of ability. We find bodyweight has little effect on math or reading for girls, but is negatively related to test scores and teacher assessments in science. Obese boys are found to have lower test scores in math and are assessed more negatively by teachers in all three academic areas. We also examine bodyweight and noncognitive skills, finding negative relationships for both girls and boys. Obesity-related differences in these skills mitigate observed disparities for boys between teacher assessment and test scores in the areas of reading and math but not science. Finally, we explore whether bodyweight differentially affects teacher and parent-assessment of children's noncognitive traits, finding a more negative effect on teacher-assessed skills.

本文使用2010-2011年儿童早期纵向调查幼儿园班级的数据，增加了有关儿童体重和人力资本的文献。我们研究体重与孩子的考试成绩和教师能力评估之间的关系。我们发现体重对女孩的数学或阅读影响不大，但与科学中的考试成绩和老师评估负相关。发现肥胖男孩的数学考试成绩较低，并且在所有三个学术领域中，教师对它们的评价都较差。我们还检查了体重和非认知能力，发现男孩和女孩之间都存在负面关系。这些技能中与肥胖有关的差异可以缓解男孩在阅读和数学领域但在科学和数学领域教师评估和考试成绩之间的差异。最后，
