Birth weight, type 2 diabetes, and insulin resistance in Pima Indian children and young adults.

Abstract

Low-birth-weight Pimas are thinner at ages 5-29 years, yet they are more insulin resistant relative to their body size than those of normal birth weight. By contrast, those with high birth weight are more obese but less insulin resistant relative to their body size. The insulin resistance of low-birth-weight Pima Indians may explain their increased risk for type 2 diabetes.
