The genetic predisposition, environment factors, physical activity and the child's food significantly affect growth rates of the child. Verification of the current parameters of growth with norm, will help to define lag or advancing of development of the kid.
Features of growth of children
Since the birth the child continuously grows, accelerating, reducing rates. Most intensively growth is observed in the first years of life. By seven years growth slows down, and to twelve accelerates again. Sometimes, behind growth of the kid internals will not be in time. However by the end of teenage age everything will be balanced.
Imperceptibly in the early childhood, but it is obvious at a teenage stage, a difference in growth indicators at boys and girls. Growth rates are affected by genetic predisposition. If parents of low growth, you do not expect that their child will have a big increase of growth during growing. It should be taken into account also factors of the environment, in the cities with an adverse ecological situation of a deviation it norms in physical development of children are observed more often. If the ecological situation is not subject to parents, then the dream and healthy nutrition prevents negative consequences and help the child to raise and develop correctly.
For normal physical development children need to have the constant physical activity and physical activity corresponding to their age.
Norm of growth at girls
At the birth growth of girls averages 49 cm. By a year the increase makes 16 cm. By three years of the girl have growth - about 95 cm. The growth rate is not reduced also by 5 years, at this time it already varies from 108 to 110 cm. Little schoolgirls, on average, about 120 cm in height. After seven years of the girl add 5-6 cm a year, and by 10 years the height meter shows 138-140 cm.
Norm of growth at boys
Newborn boys are born, having growth a little more, than girls have 50 cm. In 12 months the kid will grow by 17 cm. In 3 years boys of 96 cm in height that differs on only 1 cm from norm for girls. The five-year-old boy, on average, has height of 110 cm. In 7 years - 122 cm. By 10 years at boys growth indicators - 137 cm decrease.
Reasons for rejection from norm of growth
Parents need to watch constantly parameters of growth of the child, the delay can testify to a deviation in physical development. Experts consider the lag reasons: prematurity of the child, a trauma during the birth, rickets and adverse social conditions.
In case of an essential aberration it is necessary to undergo medical examination.
Acceleration - the accelerated growth of the child, is an aberration too, though does not meet so often. At children with the accelerated growth the increased fatigue and reduced working capacity is observed.
