Prevention of childhood obesity needs to begin before a woman ever gets pregnant.

It looks like it starts very early.

Obesity continues to rise in adults. And that risk has increased in children, too. Interventions should begin immediately for children who are already overweight at these young ages.

It's important for women to understand that their weight status does matter long-term to their children's weight status.
