8–17 éves gyermekek légzésfunkciós és testszerkezeti mutatói kapcsolatának vizsgálata

Abstract

The development of children’s respiratory functions and body structural parameters, as well as the relationship between body structural and respiratory parameters were analysed in a subsample of the Second Hungarian National Growth Study (n: 1339 children, aged between 8–17). The spirometric parameters (forced vital capacity, forced expiratory volume in the 1st second, peak expiratory flow in 1 minute) of children were recorded alongside their body structural parameters. The nutritional status of children was assessed by body mass index, children were divided into underweight, normal, overweight and obese subgroups. There was a significant difference between the two sexes’ respiratory functions in each age-group starting from the age of 13 years. While girls’ pubertal growth started to come to an end at the age of 15 years, boys’ developmental changes only slowed at the age of 17 years and continued even after. By considering nutritional status, it could be observed that overweight and obese children surpass their peers in spirometric functions in almost every age-group. We recommend the use of references of body weight-related spirometric parameters for paediatric use in overweight and obese children, such references of the three studied spirometric parameters are constructed on the basis of the studied sample of Hungarian children. The children scoring below the 5th centile should be considered for further respiratory examinations.
