Head circumference reference data for Egyptian children and adolescents

Data from a cross-sectional study of 27 826 healthy children in Cairo, Egypt, were used to construct standard growth charts of head circumference and reference values of relative head circumference to length/height for each sex. The sample was collected during the Egyptian Growth Curve Project for children and adolescents in 2002. Values were obtained for each month cohort for children aged 1–24 months, then for each year cohort until age 18 years. The values were compared with those of other populations. The constructed growth standards are suitable for growth monitoring programmes throughout Egypt.
