Growth and puberty in a fostered kindred
- 19 Downloads
A kindred of four children of different ages was at the same time adopted and transferred from a very poor to a fairly good environment. A rapid catch-up growth was observed in all four during the first 2 years after adoption. Beyond the 2nd year, physical development varied according to age, sex, and the rhythm of sexual maturation. Puberty was not advanced. Final height depended mainly on the height at the onset of puberty. The homogeneity of this familial story can contribute to a better understanding of the age-related interactions between the nutritional and environmental conditions and the genetic factors in human development. The growth and puberty of children coming from poor areas of the world to be fostered in families living in industrialized countries may shed some light on the role of nutritional and environmental factors in human development.
