NAFLD in Adolescents and Young Adults With PCOS

This project focuses on an at-risk adolescent and young adult population who may gain long-term health benefits from detection of risk factors at a young age. The primary aims of this proposal are: 1) To observe whether adolescents and young adults with Polycystic Ovary Syndrome (PCOS) are more likely to have elevated liver fat (\>/=4.8%) than controls by studying liver fat deposition measured by magnetic resonance spectroscopy (MRS); 2) To assess the association of percentage liver fat with biomarkers of Non-alcoholic fatty liver disease (NAFLD), dyslipidemia, insulin resistance and body composition in PCOS and controls. In the proposed study, 40 adolescents and young adults with PCOS and 40 age-comparable control subjects will be evaluated for metabolic disturbances and elevated liver fat using noninvasive and state-of-the-art techniques including MRI, dual-energy x-ray absorptiometry and an oral glucose tolerance test in order to fully assess the metabolic and body composition differences between these groups. This research proposal represents a critical step in understanding the metabolic and cardiovascular comorbidities of PCOS and their relationship to NAFLD. The investigator hopes to use the results generated by this research proposal in order to lay the groundwork for the prevention and treatment of metabolic disorders in adolescents with PCOS. The overarching goal is to decrease and prevent lifelong morbidity associated with this common disorder.

Inclusion Criteria: * All: Healthy; between 14 and 25 years; at least 2 years postmenarche * PCOS: Clinical hyperandrogenism and/or hyperandrogenemia, menstrual dysfunction (oligomenorrhea or amenorrhea) and exclusion of other known disorders. PCOS will be diagnosed using the NIH 1990 criteria. * Controls: Regular menses; no clinical hyperandrogenism and/or hyperandrogenemia Exclusion Criteria: * Past or present history of a medical disorder or medication known to affect body composition, insulin secretion and sensitivity, or the growth hormone (GH)-insulin-like growth factor 1 (IGF1) axis (eg steroid hormone or thyroid replacement). * History of current or past pregnancy * Hormonal contraceptive or metformin use within 3 months of enrollment * Nonclassical congenital adrenal hyperplasia
