Kids' Waists May Show Pre-Diabetes Problem
Big Waists May Predict Blood Sugar Problems, Metabolic Syndrome
Aug. 1, 2005 -- Children with large waists are more likely to have trouble
controlling their blood sugar.
The blood sugar problem, called insulin resistance, rears its ugly head
before obvious diabetes develops.
In insulin resistance, the body starts to lose its ability to respond to the
hormone insulin. Insulin helps to move sugar (glucose) from the blood into the
cells to be used for energy. As insulin resistance worsens, the body's blood
sugar levels slowly rise.
Insulin resistance is a hallmark of the metabolic syndrome, a group of
abnormal conditions linked to heart disease and diabetes.
Signs of metabolic syndrome include excess body fat (especially around the
belly), insulin resistance, high blood pressure, and poor cholesterol/blood fat
Metabolic syndrome has been seen in
Waist size could be a clue about whether a child may have metabolic
syndrome, researchers write in the Archives of Pediatrics & Adolescent
Doctors working on the study included Valeria Hirschler, MD, of the Durand
Hospital in Buenos Aires, Argentina. They studied 44 girls and 40 boys aged
6-13. The kids ranged from being obese or overweight to normal weight.
Their waists were measured. The kids also got blood tests to check levels of
insulin. Insulin levels rise as insulin resistance develops.
Bigger Waists, Bigger Problem?
Larger waists were tied to insulin resistance, write the researchers. They
plan to study the kids over time.
"Waist circumference is a predictor of insulin resistance syndrome in
children and adolescents," write the researchers.
Measuring a child's waist could be a simple way for doctors to help identify
kids at risk of metabolic syndrome, write Hirschler and colleagues.
The researchers used previously created charts to determine waist sizes that
were associated with an increased risk of metabolic syndrome.
Researchers determined that waist sizes greater than 90% of other kids were
associated with too much belly fat. This level also predicted the presence of
Examples of risky waist sizes are:
- A 5-year-old boy or girl with a waist size of 22 inches or more
- A 10-year-old boy with a waist size of 26 inches or more
- A 10-year-old girl with a waist size of 25 inches or more
- A 15-year-old boy with a waist size of 31 inches or more
- A 15-year-old girl with a waist size of 28 inches or more
Metabolic Syndrome Can Be Reversed
If metabolic syndrome is found, positive lifestyle changes could greatly
improve future health.
