Introduction

The human growth curve divides into three distinct time-spans. There is a period of rapid and rapidly decelerating growth during infancy. This changes in the third year to a period of steady and slowly decelerating growth during childhood. Growth is completed by the adolescent growth spurt which, because it occurs later and is slightly greater in magnitude in boys than in girls, accounts for the sex differences in adult height.

Growth in infancy

Clinical observation of patients born with congenital hypopituitarism indicates clearly that growth hormone is important for growth from the day of birth. On the other hand, it seems likely that nutritional influences play the major role in fetal and infantile growth; such

Introduction Hormonal disturbance, in either secretion amount or function, often occurs in parallel with impairment of glucose/lipid/protein metabolism in obesity. Two pivotal hormones, insulin and growth hormone (GH), which synergistically

In a child, puberty encompasses a series of events which include the completion of growth and the maturing of the reproductive system. One of the common hormonal links between these two processes is growth hormone (GH) and, although it has been known for some time that the reproductive axis influences GH secretion and growth, increasing interest is developing in the alternative possibility of GH modifying reproductive processes.

In the normal child, there is an increase in GH secretion from mid-childhood with a shift in periodicity and an increase in pulse amplitude (Hindmarsh, Mathews & Brook, 1988). The two- to threefold rise in GH secretion during puberty is a product of the increase in pulse amplitude over the prepubertal value (Martha, Rogol, Veldhuis et al. 1989; Delemarre-van de Waal, Wennink & Odink, 1991). GH pulse amplitude is increased during early puberty in girls and at a later stage in boys, corresponding

Introduction The production and secretion of growth hormone (GH) from the anterior pituitary is stimulated by the hypothalamic growth hormone releasing hormone (GHRH) and inhibited by somatostatin ( Muller et al. 1999 ). GHRH is
