The aim of this study was to provide updated data on the pubertal development of girls and to evaluate precocious puberty in our population. Methods: This cross sectional study was conducted in 6 to 16 year old school girls during 2009-2010 in Qazvin. 2240 healthy girls from all geographical regions with every socioeconomic status were selected by a stratified multistage cluster design to obtain representative sample of population.
