More and more parents are worrying about their daughters who have become overweight. Girls who think they aren’t popular at school are at higher risk for weight gain, according to a new study. It’s long been known that being overweight can lead to social exclusion for teens, but researchers at Harvard University discovered: whether a student’s opinions of her social position played a role in her weight.

To find out, the researchers measured the body weight of nearly 4,500 girls aged 12 to 18. Two years later, the researchers found all of the girls had gained weight—no surprise, since they were all growing. But girls who thought they were less popular at school were at a 70 percent higher risk of gaining extra weight.

The researchers considered something else besides the collected information, including whether a child was overweight at the start of the study, family income, a mother’s weight, diet, television viewing habits and some other things that can affect childhood weight gain. But the opinions of girl’s popularity are more likely to affect the girls, weight.

Experts suggested that parents concerned about a girl’s weight should look not only at eating habits but also at their child's social network, encouraging relationships with friends and joining in group activities. Meanwhile schools should also organize more programs to help girls build social skills, they added.
