Heights and weights of Swedish school children born in 1955 and 1967

Samples of Swedish school children born in 1955 and 1967 were compared regarding average heights and weights from 10-15 years. The main findings were that both boys and girls had been gaining more weight than height, especially around the ages at which peak velocity generally occurs. Since the advantage in height of children born in 1967 gradually diminishes after age at peak height velocity, it seems that the height difference during puberty mainly reflects an earlier maturation of these children, compared to the children born in 1955.
