PUBERTY BEFORE AGE 10: The New Normal? “For many parents of early-developing girls, ‘normal’ is a crazy-making word, especially when uttered by a doctor; it implies that the patient, or patient’s mother, should quit being neurotic and accept that not much can be done. . . . Now most researchers seem to agree on one thing: Breast budding in girls is starting earlier. The debate has shifted to what this means.”
Plus: “Bruce Ellis, a professor of Family Studies and Human Development at the University of Arizona, discovered along with his colleagues a pattern of early puberty in girls whose parents divorced when those girls were between 3 and 8 years old and whose fathers were considered socially deviant (meaning they abused drugs or alcohol, were violent, attempted suicide or did prison time). In another study, published in 2011, Ellis and his colleagues showed that first graders who are most reactive to stress — kids whose pulse, respiratory rate and cortisol levels fluctuate most in response to environmental challenges — entered puberty earliest when raised in difficult homes. Evolutionary psychology offers a theory: A stressful childhood inclines a body toward early reproduction; if life is hard, best to mature young. But such theories are tough to prove.” Read the whole thing.
