| pubmed-article:16492692 | pubmed:abstractText | Low-birth-weight (LBW) girls who enter puberty earlier (around 8-9 yr) tend to have earlier menarche, earlier growth arrest, and a shorter adult stature. At present, there is no therapy for most of these girls. In LBW girls with early puberty, hyperinsulinemic insulin resistance could underpin their rapid transit through puberty and their loss of adult stature. We explored the effects of insulin sensitization with metformin during puberty. SETTING, DESIGN, AND PATIENTS: In an open-labeled, prospective study, 22 LBW girls (birth weight < -1.5 sd score for gestational age) with early-normal puberty (stage 2 breast development at age 8-9 yr) were randomized to remain untreated (n = 12) or to receive metformin (850 mg/d; n = 10) for 36 months (mean age at start, 9.0 yr). All girls remained untreated between 36 and 42 months. | lld:pubmed |
