Using simple clinical measures to predict insulin resistance or hyperglycemia in girls with polycystic ovarian syndrome.

Background: Polycystic ovarian syndrome (PCOS) includes insulin resistance (IR) and impaired glucose tolerance (IGT) in youth, and a greatly elevated risk of type 2 diabetes in adulthood. Identifying IR is challenging and documenting IGT requires an oral glucose tolerance test (OGTT).

Objective: Identify easily applied surrogate measures for IR and IGT in girls with PCOS.
