Obesity and student performance at school.

To review the state of research on the association between obesity among school-aged children and academic outcomes, the authors reviewed published studies investigating obesity, school performance, and rates of student absenteeism. A table with brief descriptions of each study's research methodology and outcomes is included. Research demonstrates that overweight and obesity are associated with poorer levels of academic achievement. Data on the association of child overweight or obesity with levels of attendance are too sparse to draw conclusions.
