Since height and weight are determined by genetic, racial and environmental factors, body mass index can differ from one population to another. The aim of this study was to prepare the normogram of (7-120year old) children body mass index (BMI) in Birjand and to compare it with that of with the center of disease control (CDC). Materials and Methods: This cross-sectional, descriptive, analytic study was performed in 2002 on 1928 primary school students, including 1010 boys and 918 girls, who were selected through two- stage sampling (cluster and systematic). Their height and weight were measured. Body mass index (BMI) was defined as weight- Kg / Height-m2. The relevant percentiles of BMI for sex and age were established and compared with CDC percentiles. Findings: The BMI percentiles of 7-12 year old children in Birjand were significantly lower than CDC. Mean percentile of BMI among girls of most age groups under study was 10-25 percentiles of the CDC and below 10 percentile of CDC for boys. Conclusion: Regarding the results of this study which is much below CDC, there is a difference between CDC normograms and BMI of Birjand children. This difference can be attributed to racial differences and some environmental factors. It is recommended that the regional normograms should be developed through more comprehensive studies, so that they could be used for the assessment of weight disorders among Iranian children. M3 ER -
