Abstract/OtherAbstract:
OBJECTIVE: To examine changes in insulin sensitivity (SI), compensatory acute insulin response (AIR), and β-cell function/disposition index (DI) across puberty in overweight Latino boys and girls.
STUDY DESIGN: Latino children (n = 253) were followed annually for up to 5 years. Longitudinal modeling was used to examine changes in SI, AIR, DI, and fasting and 2-hour glucose and insulin across Tanner stage.
RESULTS: In boys, SI decreased in early puberty with a recovery by late puberty. The compensatory increase in AIR was appropriate in early maturation, but after Tanner stage 3, AIR declined by more than that predicted from the recovery in SI. For girls, SI decreased in early puberty and across all stages of maturation. In early maturation, there was an appropriate compensatory increase in AIR, but after Tanner stage 3, AIR decreased. Thus, DI deteriorated across puberty in boys and girls.
CONCLUSIONS: In overweight Hispanic youth, compensatory changes in insulin secretion fails after Tanner stage 3 in both sexes, indicating β-cell deterioration during this critical period of development, thus increasing risk for type 2 diabetes.
