[Functional abilities of the teenager's body based on body mass index]

The nutrition status was investigated according to the body weight index (BWI) in teenagers studying at different educational facilities. 77.1% of male teenagers and 70% of female teenagers from among all examined subjects (1456 persons) were assigned to the group with normal BWI ranging from 18.5 to 25.0 kg/m2. Male teenagers with a lower BWI (below 18.5 kg/m20) were more often encountered in boarding schools and specialized technical-and-professional schools; as for female teenagers, subjects with a lower BWI were more often encountered in general education schools and among first-year students of high schools (24 and 43.75%, respectively). An insignificant number of teenagers with an excessive body weight was detected in all educational facilities. Finally, it was concluded that teenagers with normal BWI have the best indices of functional abilities.
