Blood Pressure Rising Among US Kids; Salty Snacks to Blame

The high volume of salt-laden snack foods consumed by American children is the culprit cited in an article published in the journal Hypertension for a marked rise in cases of high blood pressure among US kids and teens.  The percentage of kids between ages 8 and 17 with high blood pressure--a major risk factor for cardiovascular disease, heart attacks, and strokes--has increased 27 percent over the past 13 years, according to researchers.  More from NBC News:

The new research, published Monday in the journal Hypertension, positively links rising blood pressure to increasing body mass index, especially waist circumference, and sodium intake. In short, far too many American children are too fat and eating too many salty snacks.

More than a third of children and teens in the United States are overweight or obese, according to the Centers for Disease Control and Prevention. "The reason we're seeing high blood pressure in kids, is due to the obesity epidemic," said pediatrician Dr. Joanna Dolgoff.

Dolgoff has been seeing elevated blood pressure in so many of her young patients, she thought her equipment was broken.

"Recently, I've been a lot more of my patients having high blood pressure," Dolgoff, a child obesity expert and creator of the "Red Light, Green Light, Eat Right" nutrition program, said. "I thought perhaps my blood pressure machine was broken. But actually the incidence of high blood pressure in children is increasing."

Being overweight is a key risk factor for high blood pressure in adults so "it stands to reason that it would be the same in children," said Dolgoff.
