Children's Fitness Unrelated to Glucose Tolerance
Overweight Hispanic children with impaired glucose tolerance are just aboutas fit and maintain the same level of physical activity as those with normalglucose tolerance, according to a study reported in the InternationalJournal of Obesity.
Research shows that a reduced level of fitness is a risk factor forcardiovascular disease in adults. A group of investigators at University ofSouthern California and University of Alberta examined differences incardiovascular fitness—based on treadmill performance—of 173overweight Hispanic children 8–13 years old with a family history oftype 2 diabetes.
No differences in fitness were noted among those with and without glucoseintolerance, determined by an oral glucose tolerance test. This is not to saythat being sedentary is OK, but the results add information to the puzzle ofhow cardiovascular risk factors emerge. The researchers suggest that long-termstudies may provide insight into how risk develops and may help in the designof interventions for youth at high risk of type 2 diabetes.
