Aim: To create up-to-date reference standards for Turkish children, and to compare these with growth standards for US children (CDC 2000 Growth Charts) and with previous local data. Subjects and methods: Height and weight measurements of 1100 boys and 1020 girls were obtained by biannual visits to six schools located in relatively well-off districts of Istanbul city. All children came from well-to-do families and all were healthy. All measurements were made by two trained technicians. The LMS method was used in the analyses. Results: Heights of the boys and girls in all age groups were close to the updated 2000 USA growth references and showed an increase from data on Turkish children born 30 y earlier. Weight values were high compared to reference data on US children and to the older data on Turkish children.
