secular trend
Long-term population-wide changes in growth patterns and pubertal timing over generations.
17-hydroxyprogesterone
Steroid hormone precursor elevated in congenital adrenal hyperplasia, particularly 21-hydroxylase deficiency.
21-hydroxylase deficiency
Most common form of congenital adrenal hyperplasia caused by mutations in the CYP21A2 gene affecting cortisol and aldost...
acanthosis nigricans
Dark, velvety skin patches typically in body folds, often indicating insulin resistance or hyperinsulinemia in children.
ACTH stimulation test
Diagnostic test using synthetic adrenocorticotropic hormone to evaluate adrenal cortex function and diagnose adrenal ins...
adiposity rebound
The normal increase in BMI that occurs around 5-7 years of age after the initial decline in early childhood.
adrenarche
Early stage of puberty involving activation of adrenal androgen production, typically preceding gonadarche.
ambiguous genitalia
External genital appearance that cannot be easily classified as typically male or female at birth.
androgen insensitivity syndrome
X-linked disorder where individuals with male chromosomes are resistant to androgen action, resulting in female external...
androstenedione
Androgen precursor hormone that can be elevated in CAH, PCOS, and other conditions causing hyperandrogenism.
anti-Müllerian hormone
A hormone produced by developing gonads that indicates ovarian reserve in girls and testicular function in boys.
aromatase inhibitor
Medication that blocks estrogen synthesis, sometimes used to delay bone maturation and preserve growth potential.
auxology
The scientific study of human growth and development, particularly height and weight patterns in children.
bone age
Radiological assessment of skeletal maturity used to evaluate growth and pubertal development.
bone age advancement
Condition where skeletal maturation exceeds chronological age, indicating accelerated bone development.
CAH
Inherited disorders affecting adrenal steroid synthesis, commonly causing ambiguous genitalia and growth abnormalities.
CAH newborn screening
Routine blood test performed on newborns to detect congenital adrenal hyperplasia by measuring 17-hydroxyprogesterone le...
catch-up growth
Accelerated growth that occurs when children recover from growth-inhibiting conditions, allowing them to return to their...
CDGP
Constitutional delay of growth and puberty - a normal variant where children experience delayed but ultimately normal gr...
central diabetes insipidus
Condition caused by deficient production or release of antidiuretic hormone, resulting in excessive urination and thirst...
clitoromegaly
Abnormal enlargement of the clitoris, often due to androgen exposure during fetal development or childhood.
constitutional delay
Normal variant of delayed growth and puberty with eventual catch-up to genetic potential.
cranial diabetes insipidus
Condition caused by inadequate antidiuretic hormone production by the hypothalamus or posterior pituitary, resulting in...
craniopharyngioma
Benign brain tumor near the pituitary gland that can cause growth hormone deficiency and other endocrine problems in chi...
cryptorchidism
Failure of one or both testes to descend into the scrotum by the expected age.
