Obese Kids' Wrist Size May Predict Heart
MONDAY, April 11 (HealthDay News) -- The wrist size of
overweight or obese children and teens may reveal those at
increased risk of developing cardiovascular disease, says a new
Italian researchers measured the wrist circumference of 477
overweight or obese youngsters, average age 10. They also used a
painless nuclear imaging technique on about 50 of the children to
measure the fatty and bony areas of the wrist more precisely.
Blood tests were then conducted to measure the children's
insulin levels and amount of insulin resistance.
The study authors concluded that wrist circumference accounted
for 12 to 17 percent of the total variance of insulin
Insulin resistance -- a condition in which the body has
difficulty using insulin to break down blood sugar -- is a known
risk factor for cardiovascular disease. Recent studies have shown
an association between high blood insulin levels and increased bone
The study is published April 11 in the journal
"This is the first evidence that wrist circumference is highly correlated to evidence of insulin resistance," senior author Dr. Raffaella Buzzetti, of Sapienza University of Rome, said in a journal news release. "Wrist circumference is easily measured, and if our work is confirmed by future studies, wrist circumference could someday be used to predict insulin resistance and cardiovascular disease risk."
It is the wrist's bony tissue, not the fatty tissue, that
explains insulin resistance, the researchers said.
