ABSTRACT
In the 1997-1998 and 1998-1999 school years we measured head dimensions of 1600 boys from 6 to 13 years attending elementary and middle schools in towns of the Cagliari area (Sardinia, Italy). For each age, we compared the mean values for circumference, length and width of the head with Canadian standards, widely used by Sardinian pediatricians. The t-test shows that the means of the three variables are significantly lower in the Cagliari boys than in their Canadian contemporaries, with the exception of head circumference in 6 and 7 year-olds, and of head width in 10 year-olds. Therefore, it is necessary to produce specific growth charts for circumference, length and width of the head of Sardinian children rather than evaluate their growth using standards of populations with different ethnic, geographical and socio-economic backgrounds.
