Obesity may be the cause (1 out of 5 children in the United States is overweight.) Premature birth or low birth weight babies Psychosocial stressors like an absence of a mother Formula feeding: “In Puerto Rico it was found that mothers were feeding their infants soy based formulas that mimic the production of estrogen in the child’s body.” Endocrine disrupters which are, “Naturally occurring compounds or man-made chemicals that may interfere with the production or activity of hormones of the endocrine system leading to adverse health effects.” Bisphenol A (BPA) is a manmade chemical that can leach out of plastic products when heated. This can mimic or partly mimic naturally occurring hormones, or interfere or block the way naturally occurring hormones or receptors are made. Phthalate exposure: this chemical is found everywhere in industrial chemicals, building materials, food packaging, toys, etc. and can disrupt the endocrine system.

“Preventions Starts Here”
http://www.cosmeticsdatabase.com allows teens to search their favorite cosmetic product to see if there are harmful chemicals in them. • Doctor’s can diagnose early onset puberty by doing specific tests such as measuring height, weight, and bone age to determine overall bone maturity. • Doctors can recommend a medicine called Lupron that mimics the natural hormones of the body. It is a shot given once a month, with no side effects, and once the shots are stopped puberty begins again normally. • Parents and children need to educate themselves so they are prepared to handle any problems that arise with early puberty. • “The Care & Keeping of You: The Body Book for Girls,” is a good resource for both parents and their children. •
