Diabetes is More Nurture Than Nature

A study of twins suggests that the development of insulin resistance, a precursor to adult-onset diabetes, is influenced more by current body weight than by birth weight.

Low birth weight has been linked to high insulin levels. But this relationship may occur strictly in the womb, and not in later life.

Investigators studied the between birth weight, body mass index (BMI), and insulin resistance in almost 1200 female twins. They failed to find any significant relationship between weight at birth and the development of insulin resistance. There was, however, a significant relationship between insulin resistance and current weight.
