AIMS: To provide head circumference references for school-aged children in western Romania, and compare them with references from other European countries. METHODS: A total of 2742 children, aged 6-19 years, from Timis county, were examined by medical students, between February 2010-June 2011. Head circumference references were constructed by Cole's LMS method with LMSChartMaker software. The Romanian 3rd, 50th and 97th percentiles for head circumference were compared with recent references from Belgium and Germany. RESULTS: Generally, boys show significantly larger head circumference compared to girls at any age. The head circumference increments between 6 and 19 years are < 1 cm/year. Head circumference increments decrease in increasing age of the children. In girls, adult head circumference is reached at the age of 16 years, whereas head circumference growth continues, in boys, slowly until 18 years. The comparison of Romanian head percentiles with those from Belgium and Germany revealed a smaller head circumference in Romanian children (both girls and boys). CONCLUSIONS: Comparing head circumference references from Romania to those from Germany and Belgium, we found lower median head circumference in Romanian boys and girls, that could be explained by a taller stature of boys and girls in Germany and Belgium compared to Romania.
