La proporción entre la estatura y el peso corporal

Abstract

Several studies of height and weight during growrh have been published for Mexico City since 1913, which show a general increase in both measurements in recent years. In order to determine if the proportion of height and weight is nowadays the same as before, the z values proposed by Ross and Wilson (1974) for the unisex Phantom were calculated. The results showed that after the age of 7 to 8 years, the recent increase in satarure is accopanied by a bigger increase in the proportional weight, specially in girls. Comparing our data with those existing for belgian and Hungarian children up to l3 years of age, it was shown that in the European studies the proportional
weight is lower than that found in Mexico Here the results of the more recent studies are only slightly higher in the proportional
weight based on the data of Faulhaber, while that presented by
Ramos Galván is very much bigger fiom 8 to l3 years than the ones from Europe. These facts, due possibly to differences in diet. have to be taken into account when the nutritional status is evaluaied in Mexican children on the basis of the later proportional weight.
