Dynamic assessment of school students nutritive status

Abstract

In order to study the dynamics of the harmony of physical development of schoolchildren of the metropolis, 414 students of secondary schools of St. P etersburg (213 boys and 201 girls) at the age of 16 years were examined. The survey of adolescents included somatometry (measurement of length and body weight) and evaluation of nutritional status in accordance with who standards — “WHO Growth Reference 2007”. On the basis of medical documentation the analysis of changes of physical development for the period of training at school is carried out. We have revealed that the ratio of length and body weight in most adolescents was harmonious (69.1%). In girls, body weight deficit (18.5%) was registered more often than in boys (11.7%; p=0.05). In the group of boys had more students with overweight (14.9 percent) and obesity (4.7 per cent) than girls (8.5 percent; p=0.039 inch and 3.5%, respectively). During the school years, the most stable group were children with harmonious physical development: 73.3% retained the correspondence of length and body weight. In children with disharmonious variants of physical development, more pronounced changes
in nutritional status were noted. The results obtained by us are a pilot project and serve as a reason for further research with the identification of factors that have a negative impact on the growth and development of schoolchildren.
