Model showed a SA predictive capacity of 93.2% in boys and 96.8% in girls. In boys, it predicts pubarche only, with intriguing implications for understanding those processes which stimulate adrenarche (23). The second hit occurs at the childhoodjuvenility transition, using adiposity and its rebound (2,18,21) and is a second opportunity for an adaptive response to the environment. The AH was below 152cm in 7 girls, of whom 3 were characterized by paternal transmission of the advanced puberty.
