[Variability of anthropometric traits at birth in healthy children and children suffering from acute respiratory diseases in the first year of life].
Variation of 5 anthropometric traits at birth in groups of normal children who had suffered from acute respiratory diseases during their first year of life was studied in Russian migrant and native population inhabiting the Western area of Baikal-Amur Railway. It was shown that affected children from migrant and native population had lower average values of all traits, as compared with normal children. In order to reduce the number of variable, the principal component analysis was applied. Stronger similarity was found between groups of normal children from native and migrant populations than between normal children and affected children from one population. This can be the evidence of the formation of similar adaptive norm for children from both Russian populations.
