Context: Most of the estimates of the prevalence of hyperandrogenic states refer to the general adult population. Objective: The objective of the study was to estimate the prevalence of hyperandrogenic states in late adolescence and youth and to evaluate potential independent predictors. Design: This was a cross-sectional study. Setting: The study was conducted in high schools. Patients: Patients included female students, aged 16-19 years. Main Outcome Measures: The study protocol was designed with 3 possible levels of participation: the first level consisted of a self-compiled questionnaire; the second level added a medical examination; and the third level added a blood sample for laboratory testing. Liquid chromatographytandem mass spectrometry was used to measure total testosterone, and a reference interval was established in-house. Results: We offered participation to 2052 students, and 1469 of those compiled the questionnaire. Of these, 1038 were examined, and 519 also provided blood samples. Two hundred three of the 1038 examined students and 125 of the 519 students who provided blood samples were subsequently excluded because of treatment with oral contraceptives or because of endocrine disorders. In the sample of women with a questionnaire + a medical examination, 13% were affected by isolated menstrual irregularity, 16.1% by isolated clinical hyperandrogenism, and 3.8% by both states. A similar prevalence of isolated menstrual irregularity (10.2%) and isolated clinical hyperandrogenism (16.7%) was found in the subsample of women with laboratory tests; in addition, 6.6% showed isolated hyperandrogenemia, and 4.3% proved to be affected by polycystic ovary syndrome. Conclusions: This study provides for the first time a reliable assessment of the prevalence of hyperandrogenic states in late adolescent and young females and confirms that hyperandrogenic disorders originate at a young age.
