Abbreviations: AMH, anti-Müllerian hormone; BMD, bone mineral density; BMI, body mass index; FSH, follicle-stimulating hormone; HDL< high-density lipoprotein; LH, luteinizing hormone.
aAMH and insulin were log transformed to normalize their distribution. In simple regression analyses, inhibin B was related to age, Tanner genital stage, BMI Z-score, systolic blood pressure, fat mass percentage, testosterone, estradiol, AMH, FSH, LH, total bone mineral density Z-score (BMD Z score), and lumbar BMD Z-score. In simple regression analyses, testosterone was related to age, Tanner genital stage, systolic blood pressure, fat mass percentage, inhibin B, AMH, estradiol, FSH, LH, insulin, and total and HDL cholesterol. In simple regression analyses, AMH was related to age, Tanner genital stage, systolic and diastolic blood pressure, fat mass percentage, fasting insulin, HDL cholesterol, total BMD Z-score, and inhibin B, testosterone, FSH, LH, and estradiol levels.
