Immunization: childhood injuries, children"s physical size and rate of growth are related to those of their parents, heredity when diet and health are adequate, height and rate of physical growth. Genes influence physical growth by controlling production of hormones. are largely determined by heredity. Body growth and change: height and weight. Average growth is 2. 5 inches and 5 to 7 pounds per year during early childhood. Growth hormone deficiency: produced by the pituitary gland to stimulate the body to grow: again we see general growth patterns and are also advised that each child grows at their own individual rate, both in height and weight. The growth hormone (gh) acts directly, but also stimulates release of insulinlike growth factor 1 (ibf-1), which triggers cell duplication. About 2% of children suffer from inherited conditions that cause either gh or igf-1 deficiency.
