Abstract
Objective: to identify smoking, nicotine addiction, and study the parameters of external respiration using computer bronchophonography in children depending on smoking.
Materials and methods: 142 children aged 11–17 years, hospitalized in a pediatric hospital, were examined. Smoking in children was detected by questionnaire and determination of cotinine in urine, the degree of nicotine addiction was determined by the Fagerström test, and computer bronchophonography was used to assess the function of external respiration.
Results: it has been established that more than 40% of children aged 11–17 years old try to smoke and more than 27% are smokers. More than 20% of children smoke daily and have an average smoking experience of 2.5 years at this age. Every fourth smoking child has a weak to very strong nicotine addiction. When comparing the acoustic parameters of external respiration using computer bronchophonography, it was found that the indicators in the mid-frequency range were four times higher among smoking children compared to non-smoking children.
Conclusions: thus, more than 27% of children over the age of 11 smoke and have varying degrees of nicotine addiction. Smoking children have increased acoustic spectrum of external respiration in the medium-frequency range, which may indicate the predominant lesion of the middle bronchi in smoking. Computer bronchophonography is an important method of early diagnosis of respiratory pathology in smoking children.
