Premature pubarche, or the development of pubic hair before the age of 8 in girls or 9 in boys, is most commonly caused by premature adrenarche. Adrenarche is the maturation of the adrenal zona reticularis in both boys and girls, resulting in the development of pubic hair, axillary hairNoun. axillary hair (usually uncountable, plural axillary hairs) (uncountable) Androgenic hair growing in the armpit, normally beginning at the onset of, or shortly after, pubarche.https://en.wiktionary.org › wiki › axillary_hair
It's not uncommon for young children to show certain traits associated with puberty, including some pubic hair, underarm hair and the beginnings of breast development, said Dr. Paul Kaplowitz, who led the American Academy of Pediatrics report.
Hormonal basis
It is normal for production of these hormones to increase (something we call adrenarche) and for pubic hair to appear after age 8 in girls or 9 in boys. The reason why this increase occurs earlier in some children is not known.
In Stage 2, physical changes begin. Between the ages of 8 and 13, girls typically experience: Their breasts begin to bud, and their areolas (pigmented area around the nipple) enlarge. Scant pubic hair appears.
Pubic hair of infancy is due to transiently elevated androgen levels in the first few months of life and increased sensitivity of sexual hair follicles to androgens. Precocious puberty can be differentiated by the concomitant appearance of pubic hair with breast development in girls or testicular enlargement in boys.
But it's perfectly normal for puberty to begin at any point between the ages of 8 and 13 in girls and 9 and 14 in boys. There's not usually any need to worry if puberty does not start around the average age, but it's a good idea to speak to your GP for advice if it starts before 8 or has not started by around 14.
Common signs of early puberty are the appearance of pubic hair and body odor. A female might have early breast development, but this is often fatty tissue and may not lead to progressive growth.
Uterus begins to get larger, and small amounts of pubic hair start growing on the lips of the vulva.
Premature adrenarche doesn't require treatment. However, it will cause your child's body to change sooner than those of her peers, and this may make her feel self-conscious. It's important to reassure her that the changes in her body are completely normal, even if she is experiencing them earlier than other children.
Higher total protein, animal protein and meat intake in children ages 3 to 7 have been associated with earlier onset of menstruation. High protein intake elevates IGF-1 levels and promotes growth, which could accelerate the onset of puberty.
When does adrenarche start? It is a development that happens before puberty, usually between the ages of 6 and 8 years (precocious puberty). During this time certain hormones (biological messengers) begin to increase. They may either go unnoticed or can cause changes in the body like new hair growth and body odour.
Handling the Adrenarche Phase
Make sure to "be consistent, firm, and fair." And work together to come up with strategies to help your little one deal with their feelings. "One way could be to encourage them to take deep breaths when they are feeling annoyed," says Joshi.
The cause of precocious puberty often can't be found. Rarely, certain conditions, such as infections, hormone disorders, tumors, brain abnormalities or injuries, may cause precocious puberty. Treatment for precocious puberty typically includes medication to delay further development.
The reason for it is most likely genetics — if you or your child's other parent had a lot of body hair as a toddler (or someone in either of your families did), your toddler simply "inherited" the body hair. Body hair is often darker, and therefore more noticeable, on children with darker complexions.
(1999a, 2008) found that girls and boys with premature adrenarche (a clinical term characterizing high levels of DHEA and Tanner stage 2 pubic hair in 6–8 year olds) demonstrate increased levels of depression, anxiety and behavioral problems compared with their normatively developing peers.
If the clinical signs, together with elevated DHEAS concentrations, are seen before the age of 8 years in a girl or 9 years in a boy, adrenarche is regarded as premature [reviewed in Ref. (1, 2)]. In Finland, the prevalence of premature adrenarche (PA) is 8.6% in girls and 1.8% in boys (3).
Premature pubarche, or the development of pubic hair before the age of 8 in girls or 9 in boys, is most commonly caused by premature adrenarche. Adrenarche is the maturation of the adrenal zona reticularis in both boys and girls, resulting in the development of pubic hair, axillary hair, and adult apocrine body odor.
Sometimes, treatment of a related health problem can stop the precocious puberty. But in most cases, there's no other disease, so treatment usually involves hormone therapy to stop sexual development. The currently approved hormone treatment is with drugs called LHRH analogs.
Growing pubic hair
Soon after her breasts start to form, she'll start developing pubic hair. It will be soft and thin at first and then gradually become coarser. Her first period usually arrives around one to two years after pubic hair starts growing.
Some children can have different patterns. Some girls develop breasts at a very young age but have no other signs of sexual development. A few children have pubic and armpit hair long before other signs of sexual growth.
Generally, the first major signs of puberty are getting taller and the beginning of breast changes. Rapid changes in a girl's height happen later. Pubic hair often appears next, followed by the beginning of menstrual periods, full breast maturity, and the release of eggs from the ovary every month (ovulation).
Mood swings are a normal part of puberty
Your child may have strong emotions that they've never experienced before. It's common for them to feel confused, scared or angry and not know why. They also might be more sensitive and become more easily upset than usual.
Fact: There is no scientific evidence that drinking milk causes early puberty. In the United States, girls are entering puberty at younger ages than they were in the first half of the 20th century. Researchers do not know the exact trigger for early-onset puberty, although it is likely influenced by many factors.
