More than 190000 schoolchildren aged between 7 and 17 years of 232 regular schools of Rostov region (Southern Federal District of Russia) participated in current study (it is about 40% of schoolchildren living in Rostov region). The purpose of this study was to develop references for growth and physical development of schoolchildren from Rostov region. According to our data, at the period of life from 6 to 18 years children have intensive growth and physical development. The boys and girls have the similar age-related changes of weight, height and other functional parameters of organism. But girl’s height and weight values demonstrated acceleration from 10 to 12 years and its deceleration after 14 years. The height and weight values monotonically increased in boys with ages and accelerated between 12 and 13 years. The girls were taller than boys at the 11-12 years. Girls had acceleration at ages between 11 – 14 years to the weight, height, force index and respiratory output data. The boys had height acceleration since 12-13 years to 18 years and changing of height is monotonically across all ages. In whole, data of current study have showed what children’s development realized not only in relation with ontogeny but in accord with ecological and social factors too.
