Late childhood is considered to encompass ages 9through 12, approximately.

Other terms linked with late childhood are "puberty"

and "preteen.” Although most children experience puberty between

the ages of 9 and 12, some can start before age 9.

On the other hand, there are some children who arelate bloomers, not reaching puberty until age 13 or

even later. If children are either early or late in going through

puberty, it's important for parents to reassure theirchildren that there isn't anything wrong with them.



The primary symptom of late physical

development in adolescence is delayedpuberty, which is evident if a girl has shownno signs of breast development and has notyet begun her menstrual cycle by age 13.

Girls who display breast growth on time butdo not menstruate for five years also areconsidered to have late physical

development.



Basic characteristics General impact onperformance

Significant proportional changes

occur in bone, muscle, and fattissue.

Athletes may temporarily lose

some of their kinaestheticawareness, their ability to ‘knowwhere they are’.

Different parts of the body grow atdifferent rates. Arm and leg lengthincreases before the trunk.

Athletes may appear gangly andlose control of their extremities.

Decreases in flexibility resultdirectly from growth.

Movement may become restricted.

Increases in growth and decreasesin flexibility make adolescents prone to injury from acute impact.

Injury can result from exercise of an acute nature such as forcedelongation of muscles during

kicking and jumping or fromoveruse.



chromosomal abnormality diabetes

anemia

abnormal hormone levels

run in families - Learning to walk late can alsorun in families or it may be a reflection of yourchild's personality: some children are moreindependent than others, and this has a bearingon how soon they learn various skills. You mayalso find your child takes no interest in walkingfor months and then makes a sudden leapforwards (literally!).



inherited from biological parents Delays based on genetic influences are

estimated to account for about 15 to 25percent of developmental disorders.

metabolic conditions (e.g., PKU) orsyndromes (e.g., fragile-X) are examples of genetic factors that contribute to biological

changes.



Infections lead poisoning

head injuries

prenatal exposure to toxins

Some children will have delays in a particulararea, such as walking, while the rest of theirskills continue developing on or ahead of schedule. If that's the case for your child, it may

just mean he's concentrating so hardon talking or understanding that his brain haspushed walking to a back burner for themoment.

If symptoms are serious, a doctor can runblood tests, do an X-ray to observe bonematurity or, less commonly, run an MRI or CTscan.

Once the cause is determined, appropriatetreatment will begin, unless the delayedgrowth is hereditary.

Hormone therapy or surgery are possibletreatment options.
