In the first study of how weight may affect school attendance, researchers at the University of Pennsylvania and Temple University have found that overweight children are at greater risk of school absenteeism than their normal-weight peers.
The study of more than a thousand 4th, 5th and 6th graders in the Philadelphia school system also determined that body mass index, or BMI, is as significant a factor in determining absenteeism from school as age, race, socioeconomic status and gender, formerly the four main predictors.
The study found that overweight children were absent on average 20 percent more than their normal-weight peers.
"At this young age, children are not necessarily experiencing the health problems that will likely confront them later in life unless serious intervention takes place," said Andrew B. Geier, a doctoral candidate in the Department of Psychology in the School of Arts and Sciences at Penn. "However, they are missing school at a greater rate than their peers, setting themselves up for the negative fallout that accompanies absenteeism. What's keeping them from school, more than heath issues, is the stigma and the bullying that accompanies being overweight. Future research should explore this additional, very damaging side effect of being overweight."
