Figure 2-4 Correlations between adult height and height of the same individuals as children. (Source Tanner J. Growth at Adolescence, 2nd ed. Oxford Blackwell Scientific Publications, 1962.) was carried out in the 1930s by Sir John Hammond at Cambridge University.6 Using artificial insemination techniques, this research group crossed a Shetland pony mare with a Shire horse sire, and a Shire horse mare with a Shetland pony sire. Birth-weights of the foals were in accordance with maternal size....

Growth in Infancy and Childhood A Pediatric Approach Service of Growth and Development, Hospital Garrahan, Buenos Aires, Argentina At birth the infant is delivered into a postnatal environment characterized by extremely varied and changing conditions. He or she will be subject to intense and continuous physiological demands, which will require consequent adaptive responses during the first years of life. Growth evolving under these circumstances becomes a central subject in pediatric practice,...

Figure 1-3 The growth of De Montbeillard's son 1759-1777 Velocity. (Redrawn from Tanner JM. Growth at Adolescence, 2nd ed. Oxford Blackwell Scientific Publications, 1962.) growth is smooth and rapid during the first half of pregnancy. Indeed, it is so smooth between 11 and 14 postmenstrual weeks, when the growth velocity is 10-12 mm week-1, gestational age can be calculated from a single measurement to within 4.7 days. The 95 error band when three consecutive measurements are taken is 2.7 days....

Et al.59 found a larger sex difference in adult height D 14.2 cm , mainly due to a relatively more important adolescent gain than in the British children, whereas data for the Belgian population show, such as for the British children, a relatively larger contribution of DT to the sex differences in adult height.60 Table 3-2 shows that the decomposition of adult sex differences in sitting height is percentagewise table 3-2 Decomposition of Sexual Dimorphism in Adult Size of Height, Sitting...
