title: Update on pubertal development.
abstract: This review provides updated information relating to the timing of pubertal onset from a large study of girls seen in pediatric practices. In addition, new studies investigating the relationship of the hormone leptin to the onset of puberty are discussed, as well as new information on the neuroendocrine control of pubertal regulation. A provocative study documenting poor mental health, more behavior problems, and lower IQ in children with premature adrenarche when compared with controls raises the question of whether psychological stress triggers premature adrenarche or whether the early increase in adrenal hormone secretion causes psychosocial problems. Finally, significant advances in the management of central precocious puberty in girls have been made over the past year.
