Features of Physical Development in Adolescents Aged 12–14 Years: Assessment and Analysis

Abstract

BACKGROUND: The review examines the main stages of the formation of anthropometric monitoring of the physical development of children and adolescents in pediatric practice. Various factors that have a complex effect on the growth and physical development of the child’s body are shown. AIM: The aim of research is to identify features of physical development in adolescents aged 12–14 years and make assessment and analysis. The importance of conducting modern research to determine the anthropometric indicators of the norm for children and adolescents living in different regions is indicated. The research was conducted in educational institutions. METHODS: A total of 756 boys and girls aged 13–14 were examined. The study of the main trends in the formation of physical and sexual development of children and adolescents over the past decade can serve as a basis for the development of measures to preserve reproductive health. RESULTS: Assessment of the physical development of children showed that 72-73% of children aged 13-14 years have a harmonious (normal) physical development. Among 14-year-olds, the deficit is relatively more common among girls, and the excess is the opposite among boys. CONCLUSION: The progress of the external signs of puberty at the height of puberty was determined by the actual age (internal clock, i.e., the genetic program) and, in addition, and independently of this, the achieved body weight.
