Short height. Children with precocious puberty may grow quickly at first and be tall, compared with their peers. But, because their bones mature more quickly than normal, they often stop growing earlier than usual. This can cause them to be shorter than average as adults.
All puberty variables had high internal consistency. In girls, earlier age of menarche, breast development, and growth spurt were related to shorter height. In boys, earlier age of growth spurt and slower progression through puberty were related to taller height at age 18 years.
Myth: menarche means the end of growth is near
The reality is that the average gain in height after menarche is about 7 cm (3 inches), and it is even greater for girls who menstruate on the early side of normal.
Children with early puberty are more at risk for low self-esteem, depression, and substance abuse. Your son or daughter may require counseling to help address the changes in their body and the effects of any treatments they receive.
The average age for girls to start puberty is 11, while for boys the average age is 12. 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.
What causes precocious puberty? It may be caused by tumors or growths on the ovaries, adrenal glands, pituitary gland, or brain. Other causes may include central nervous system problems, family history of the disease, or certain rare genetic syndromes. In many cases, no cause can be found for the disorder.
A major growth spurt happens at the time of puberty, usually between 8 to 13 years of age in girls and 10 to 15 years in boys. Puberty lasts about 2 to 5 years.

Puberty effects on health
“Early puberty in girls has been associated with increased risk of breast cancer, ovarian cancer, obesity and even diabetes in adult life,” Chapa said. “Some of these conditions are related to prolonged and early exposure to estrogen from the active ovarian cycle.”
Some research suggests that early puberty might compound the problems associated with early adversity to boost the risk of depression and other mental health problems even higher. "These risk factors may be additive," Graber says.
In general, boys begin puberty between the ages of 10 and 13 years old and experience growth spurts between 12 and 15 years old. This means their biggest growth spurt happens about two years after it does with girls. Most boys stop gaining height by age 16, but their muscles may continue to develop.
How Tall Should a 12 Year Old Be? We can only speak to national average heights here in North America, whereby, a 12 year old girl would be between 137 cm to 162 cm tall (4-1/2 to 5-1/3 feet). A 12 year old boy should be between 137 cm to 160 cm tall (4-1/2 to 5-1/4 feet).
Boys tend to show the first physical changes of puberty between the ages of 10 and 16. They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
Genetic changes happen randomly. There is nothing a parent could do before or during pregnancy to prevent this change from happening. A genetic counselor can help determine the chances of having a child with dwarfism. Depending on the type of dwarfism, two average-height parents can have a child with short stature.
The genetics of height
If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents. Genes aren't the sole predictor of a person's height. In some instances, a child might be much taller than their parents and other relatives.
On average, boys reach puberty later than girls, and researchers have found that the differences in the onset of puberty could explain around half of the gender differences in grades. “Pupils who reach puberty earlier perform better. This applies to both boys and girls.
Most cases of early puberty cannot be prevented. Limiting your child's exposure to reproductive hormones from outside sources may prevent precocious puberty. These sources may include estrogen or testosterone creams, lotions, or other medications.
When do most girls get their period? Most girls get their first period when they're between 10 and 15 years old. The average age is 12, but every girl's body has its own schedule. Although there's no one right age for a girl to get her period, there are some clues that it will start soon.
For girls, puberty usually starts around age 11. But it can start as early as age 6 or 7. For boys, puberty begins around age 12. It can start as early as age 9.
Most boys with constitutional delayed puberty are short compared with their peers, but because they have a delayed growth spurt, they usually catch up to other boys by the time they are 18 and have heights in the normal range as adults.
Genetics plays the biggest role in a person's final adult height. The best predictor of height is parents' height or, more specifically, midparental height. You can calculate midparental height by adding the mother's and father's height in inches. Add 5 more inches for boys or subtract 5 inches for girls.
An adolescent may grow several inches in several months followed by a period of very slow growth, then have another growth spurt. Changes with puberty may occur gradually or several signs may become visible at the same time.
The most common cause of short stature is having parents whose height is below average, but around 5 percent of children with short stature have a medical condition. Conditions that can underlie short stature include: undernutrition, due to a disease or lack of nutrients.
