Factors affecting the growth

     Each child has a particular rhythm of development, but the process by which individual growth is identical in all cases. The differences are explained in this evolution is interpreted as the sum of a series of factors that influence each other to determine. Some correspond to inherent aspect of the subject's physiology, and are both internal, others no less essential, are derived from their relationship with various elements of the external environment and are considered, therefore, external.

The main internal factors we highlight the following:

HERITAGE: genetic endowment that the child has received from its parents contains coded information that determines a potential level of development. (This however continues to depend on other factors, internal and external, being practically impossible to distinguish which correspond to each of them).

ENDOCRINE SYSTEM: In the first months of life, growth is regulated primarily by the thymus, pancreas and adrenal cortex; later thyroid begins to intervene, and soon after, the pituitary, the proper functioning of the endocrine system, thus, it is a prerequisite for child development.

METABOLISM: Equally essential are the basic processes of metabolism: digestion, intestinal absorption, gas exchange, blood flow and renal activity, feeding alone is not enough for the child to grow, as exist in metabolic functions dramatically altered, never be able to fulfill its mission to fully satisfy the needs of the organism.

External factors determining growth we find two fundamental causes, the food supply and the whole environment.

NUTRITIONAL CONTRIBUTION. The full development of the individual is impossible without a sufficient intake of protein and vitamins. The lack of a food material, especially in primordial times of growth irreversibly affects the child. A severe lack of vitamin D, for example, in the first years of life, is the cause of rickets, a disease whose consequences persist in the adult.

ENVIRONMENT. Should be included in this section from the weather and geographical conditions to socioeconomic and cultural situation of the family environment and the context of close relationships, are all certainly very heterogeneous aspects, but that influence child development, and influence, reciprocally, with extreme importance because nobody puts in discussion.

Food is essential for growth, but any impaired metabolism without any effect.

                   

ON CHILD GROWTH FACTORS INVOLVED within the organism, such as heredity, endocrine or metabolism, but are equally FURTHER FACTORS DETERMINING THE INDIVIDUAL AS FOOD, the geographical environment, the socioeconomic environment FAMILY, ETC.
