Brief Summary
The purpose of this study is to learn if obese pre- and early pubertal girls with hyperandrogenemia (HA) are more insulin resistant (i.e., have lower insulin-stimulated glucose disposal) compared to obese peripubertal girls without HA; and that overnight mean luteinizing hormone (LH) concentration is also an independent predictor of free testosterone concentrations, especially in mid- to late pubertal girls.

Study Arms (1)
peripubertal obese girls
Peripubertal obese girls, aged 8 - 16 years, who are obese (BMI-for-age percentile greater or equal to 95)
Eligibility Criteria
Generally healthy peripubertal girls ages 8 - 16 years with a BMI of \> or = to 95th percentile will be recruited from the general population of the surrounding area.
You may qualify if:
- Peripubertal (Tanner stage 1 to 5) girl, age 8-16 years
- Obesity (BMI-for-age ≥ 95th percentile)
- Generally healthy (save for exogenous obesity)
- Ability and willingness of subject/parents to provide informed assent/consent
You may not qualify if:
- Age \< 8 or \> 16 y
- Greater than 4 y post-menarche
- Obesity associated with a diagnosed (genetic) syndrome (e.g., Prader-Willi syndrome, leptin deficiency), obesity related to medications (e.g., glucocorticoids), etc.
- Pregnancy or lactation
- Virilization
- Total testosterone \> 150 ng/dl, which suggests the possibility of a virilizing neoplasm
- DHEAS greater than twice upper limit of age-appropriate normal range
- OHP greater than 250 ng/dl, which suggests the possibility of congenital adrenal hyperplasia (if postmenarcheal, the 17-OHP will be collected during the follicular phase, or \> 60 if oligomenorrheic) NOTE: If a 17-OHP \> 250 ng/dl is confirmed on repeat testing, an ACTH stimulation test will be offered, with a post-ACTH 17-OHP \< 1000 ng/dl being required for study participation
- History of premature adrenarche (i.e., appearance of pubic and/or axillary hair before age 8)
- Fasting glucose \> 125 mg/dl or hemoglobin A1c \> 7.0%
- Abnormal TSH or prolactin
- Evidence of Cushing's syndrome by history or physical exam (e.g., history of impaired growth, striae)
- Hematocrit \< 36% or hemoglobin \< 12 g/dl
- Significant and current cardiac or pulmonary dysfunction (e.g., known or suspected congestive heart failure; asthma requiring systemic intermittent corticosteroids; etc.)
- Abnormal liver enzymes, age-specific alkaline phosphatase, or a bilirubin \> 1.5 times upper limit of normal
- +2 more criteria
