title: [Specific features of sexual maturation in urban and rural adolescent girls].
abstract: Eight hundred and fifteen adolescent girls aged 14 to 17 years who live in Orenburg and rural areas have been examined. The age-specific and regional features of their physical and sexual maturation were studied. Assessment of the findings suggests that there are differences in the processes of physical and sexual development between urban and rural adolescent girls. Early identification of the factors that influence the development of senior schoolgirls will allow one to implement preventive measures to preserve reproductive health in the girls.
