Insulin resistance in pregnant women with and without polycystic ovary syndrome, and measures of body composition in offspring at birth and three years of age.

In our cohort, maternal polycystic ovary syndrome was not associated with insulin resistance after correcting for body mass index and was not an independent predictor of offspring birthweight. However, both polycystic ovary syndrome and high maternal body mass index may increase risk of childhood obesity at three years of age.
