Obesity
Ups Kids' Health
Risk More Than Expected
Obese children are more likely
than previously thought to develop a cluster of health conditions
that put them at increased risk of diabetes and cardiovascular
disease, results of a new study suggest.
The more weight children gain,
the more likely they are to develop so-called metabolic syndrome,
researchers report.
"Obesity in children and adolescents
can lead to a number of complications like high blood pressure,
type 2 diabetes and so forth," Dr. Sonia Caprio stated.
"Obesity is not a cosmetic issue
and preventive measures ought to be implemented to stop further
weight gain," said Caprio, who is at Yale University School of
Medicine in New Haven, Connecticut.
The metabolic syndrome is a cluster
of risk factors that often precedes type 2 diabetes and cardiovascular
disease. Signs of the metabolic syndrome include abdominal obesity,
high levels of blood fats called triglycerides, low levels of
HDL ("good") cholesterol, high blood pressure and high blood sugar.
It's no secret that the waistlines
of America's children and teens are rapidly expanding, so Caprio
and her colleagues set out to measure the relationship between
obesity and a variety of health risk factors.
The study included 439 obese children
and adolescents as well as 20 of their non-obese brothers and
sisters and 31 overweight siblings.
Obese children and adolescents
were at high risk of the metabolic syndrome, Caprio and her team
report in this week's issue of The New England Journal of Medicine.
Almost 39 percent of moderately
obese children and almost 50 percent of the severely obese were
classified as having the metabolic syndrome. The higher a child's
body mass index (BMI) -- a measure of weight in relation to height
- the greater was the risk of the metabolic syndrome.
"Our findings suggest that the
metabolic syndrome is far more common among children and adolescents
than previously reported and that its prevalence increases with
the degree of obesity," the team writes.
Obesity was also associated with
an increased risk of impaired glucose tolerance, a condition marked
by elevated blood sugar levels that often precedes type 2 diabetes.
"If the weight and degree of obesity
increases, the child or the adolescent is at risk for the development
of type 2 diabetes and cardiovascular disease at a young age,"
Caprio said.
In fact, among a group of children
and adolescents who were re-examined two years later, eight participants
who already had the metabolic syndrome had developed type 2 diabetes.
Future studies should examine the
underlying causes of the metabolic syndrome in children and how
to reverse it, Caprio said. "More importantly, we need to prevent
childhood obesity," she said.
