What do I need to know about obesity in children?

Childhood obesity is growing at an alarming rate and statistics show that children who are obese will grow up to be obese adults.

Childhood obesity has the same basic cause as adult obesity: too many calories are consumed and there is not enough physical activity. Children do need extra nutrients and calories for growth and will gain weight in proportion to that growth. But when children eat more calories than they need, they gain weight. Some genetic diseases and hormonal disorders also cause childhood obesity, but those affect a small number of children.

Doctors determine childhood obesity by calculating a child’s body mass index (BMI). They compare that to a national BMI-for-age growth chart. The chart allows a doctor to compare the child’s BMI to other children of the same sex and age. If a child’s BMI is between the 85th and 94th percentiles (that means that between 85 and 94 percent of children of that age have a lower BMI), the child is overweight. If BMI is at the 95th percentile or above, the child is obese. The doctor also looks at family history, the child’s eating habits and activity level to determine healthy weight.

The best way to prevent – and treat -- childhood obesity is for children to eat a healthy diet and increase their physical activity. Parents must make sure they provide the right foods (such as fruits, vegetables, and healthy snacks) and limit the times the family eats out. It is also good for parents to make sure their children are physically active, even if they just go outside and play. Weight loss drugs and surgery are available for adolescents, but they are rarely used and do not replace the need for a healthy diet and regular physical activity.
