Several methods have been used to estimate adiposity with high precision, but BMI has becomethe most common marker in identifying overweight and obese subjects. This study was performed to presentreference data for body mass index (BMI) of school children aged 6.5-11.5 years in Shiraz, southern Iran.Methods: The data of present study are based on a random multi stage sample survey of 2397 healthy schoolchildren in Shiraz, southern Iran. The participants were 1268 boys and 1129 girls and their heights and weightswere measured in 2002-2003 academic year. Joint height-weight measurements were available for 2195 (91.6%)including 1138 boys (89.7%) and 1057 girls (93.6%). Healy-Rasbash-Yang (HRY) distribution-free method wasapplied to estimate BMI age-related centiles.Results: Cubic polynomials in age are shown to adequately fit the BMI data (on log scale). Children are nowheavier than those born over ten years earlier. Boys BMI lie above girls to around 10 years of age, which is subsequentlyreversed for overweight and obese centiles.Conclusions: Comparison of these BMI curves with those of CDC charts showed substantial differences atevery age and suggested the necessity for the use of locally based BMI norms for assessing body mass index ofchildren in Shiraz, Southern Iran. Also, a positive secular trend in BMI is seen during the past decade in Iran.
