Although childhood obesity rates have stabilized, the fight to combat the epidemic is far from over, according to American Heart Association Deputy Chief Science Officer Eduardo Sanchez, M.D., M.P.H.

Dr. Sanchez tells parents in a video that they must work closely with schools and communities to help children reach and maintain a healthy weight.

He suggests parents remember the numbers 5, 2, 1, 0  as they work to introduce and maintain healthy habits.

“Five is five servings of fruits and vegetables a day. Two is the number of hours maximum that children should spend looking at a screen. One is the one hour, at least, of physical activity that they should be engaged in. And zero is about zero calories when you are hydrating yourself,” he said.

The interview appears on, which offers information on a variety of health topics and is hosted by several Blue Cross and Blue Shield divisions of Health Care Service Corp.

One third of children in the United States are overweight or obese, meaning they are likely to face early heart disease, disability and possibly death.
