Metabolic and cardiovascular risk factors in subjects with impaired fasting glucose: the 100 versus 110 mg/dL threshold.

Background: In 2003, the American Diabetes Association (ADA) established a new cutoff for impaired fasting glucose (IFG) by reducing it from 110 to 100 mg/dL. This change was challenged as to its appropriateness. A few studies have examined the impact of the ADA(2003) threshold of IFG on metabolic and cardiovascular risk factors.
