Child Heart Disease Risks on the Rise
Early Prevention Efforts for Hypertension and Obesity Needed to Stave Off Epidemic of Heart Disease

Oct. 10, 2008 (New York) -- The rate of premature heart disease among obese teens is set to triple, and the increasing
prevalence of high blood pressure in children is a major culprit,
experts warned at a news conference sponsored by the American Society of
"The presence of child obesity results in higher rates of high blood pressure," which is a major risk factor for
stroke and heart attack, said Bonita Falkner, MD, a professor of
medicine and pediatrics at Thomas Jefferson University in Philadelphia.
"This is a problem that is not going to magically go away, and it puts
children at risk for premature cardiac events at an earlier period in their
The statistics are staggering. Seventeen percent of children are obese and
20% are overweight, which means that about 12 million children under age 18 are
overweight or obese, Falkner says.
As it stands, 3.5% of children have high blood pressure and another 3.5%
have pre-hypertension, meaning that they are at risk of developing high blood
pressure in the future.
There is no magic number that defines high blood pressure in children.
Instead, a child's sex, age, and height are used to determine age-, sex- and
height-specific systolic and diastolic blood pressure percentiles.
Pediatricians typically begin to measure blood pressure when a child turns 3 as
part of a standard well visit.
Metabolic Syndrome Risks
What should concerned parents and pediatricians do to ward off this
potentially devastating health crisis?
"If we have a child with obesity plus high blood pressure, that is a
child that we should have further evaluated for other risk factors such as cholesterol, sleep apnea, or sleep disturbances and if they have a family history of
diabetes, they may need further screening of [blood
sugar] metabolism," Falkner said. Obesity and high blood pressure are two
components of metabolic syndrome, a cluster of risk factors that
increases the risk of heart attack, stroke, and diabetes.
"They just need one more risk factor and they have the syndrome,"
Treating children with essential high blood pressure (high blood pressure
that is not caused by another disease or condition) starts with lifestyle
changes. This means "trying to modify diet, increase physical activity, and if they are overweight, controlling
their weight," Falkner says. "In children with more
severe hypertension and no response to a reasonable period of lifestyle changes
[who have] evidence of organ injury [from the high blood pressure], medication is indicated."
The same drugs that are used to treat adults with high blood pressure are
also used in these children. These drugs do have side effects, Falkner says,
and "we are very concerned about the side effects of these drugs and up
until the last 15 years we have been doing this blind without data on
