Summary

Objective: to study the indicators of the physical development of children in the city of Cheboksary and to identify risk factors affecting the physical development of children with chronic nasopharyngeal infection.

Material and methods: The study of the developmental histories of 167 children from 7 to 17 years old with chronic tonsillitis and 370 children with chronic nasopharyngitis was conducted. The control group consisted of 32 healthy children.

Results: The largest lag in the body length of children with chronic nasopharyngitis (CN) compared with the control group is 7-9, as well as 16-17 years of age. The lag in the growth of children with chronic tonsillitis begins from 10–13 years of age, with a maximum at the age of 16–17. The body weight of children with CN is lower in all groups; at the age of 14-15, it approaches the mass of children in the control group. The body weight of children with chronic tonsillitis (CT) compared with the control group is significantly lower for children under 15 years old inclusive, and in older age there is an advance in body weight. There was a significant reduction in body mass index in children with chronic tonsillitis in all age groups compared with the control group. There is a decrease in the performance of dynamometry of children with chronic nasopharyngeal infection (the power index is below the average found in 90% of children). In spirometry indicators of children with chronic nasopharyngeal infection, changes in the form of light restriction were detected in 63% of cases. The greatest lag in sexual development was in girls with CT (75%) and boys with CN (64.8%). In girls, the lag in the formation of secondary sex characteristics was detected more often in 12-13 years, in boys, starting at the age of 14.

Conclusion: Children with chronic foci of infection have changes in the indicators of physical development, functional indicators (spirometry, dynamometry), which makes it possible to conclude that these foci have a direct effect on the physical development of children. Identified risk factors in children with delayed physical development and chronic nasopharyngeal infection. These include frequent exacerbations of acute respiratory infections and sore throats, leading to even greater changes in the tissues of the Pirogov-Valdeyer lymphoid ring and the further formation of a chronic focus of infection. A significant number of disorders of sexual development of children with chronic tonsillitis compared with the control group was revealed. Therefore, children with chronic nasopharyngeal pathology are in a high-risk group, which requires timely preventive measures.

 Key words: children, nasopharyngeal pathology, physical development, spirometry.
