A new study has claimed to have discovered a link between obesity and lower academic achievement among teenage girls.

The research found that girls who were obese at the age of 11 had lower attainment at ages 11, 13 and 16 when compared to those of a healthy weight.

Adolescent girls who were obese were found to achieve grades "lower by an amount equivalent to a D instead of a C", researchers said. The study found no similar link among boys of the equivalent age.

The research, carried out by Dundee, Strathclyde, Georgia and Bristol universities was published in the International Journal of Obesity and claims to be the most comprehensive of its kind.
