Constitution and growth biology of 6 to 7 years old children from a European city ("Braunschweiger Längsschnitt") and a country with rather original habits (extreme rural area of Kenya, "Abaluya"--administrative name of Bantuid tribes from W-Kenya--out of the region of Idakho and Tiriki, elevated in spring 1990) were comparatively studied. To achieve comparability in physique and body height, the elevated data were "allometrically standardized". The statistical parameters and the results of correlation statistics were shown by comparing the two groups of children. This paper is thought to be the first attempt of a more extensive study in which further more comparative data from other age groups of children and different ecological factors as climate or nutrition should be involved in the analysis. At least the knowledge of standardized data is a cogent assumption to judge about constitution, typology and health of populations.
