Childhood obesity is proving to be a problem not only at the doctor's office but in the classroom as well—especially for girls. Researchers looked at 6,000 children in the United Kingdom ages 11 to 16 and found that only 15 percent of them were at a healthy weight. Obese students, primarily girls, had a higher chance of receiving a D instead of a C, which was used as an "average" grade in the study. Results, which were published in the International Journal of Obesity, showed that the weight-grades correlation was not as prevalent in boys.
"Researchers took into account factors like socio-economic deprivation, mental health, IQ and age of menarche for the study," according to Red Orbit. Those factors, however, did not change the connection between obesity and lower grades.
