Abstract
OBJETIVO: Fornecer valores de referência e avaliar os fatores que influenciam a mobilidade torácica de crianças entre sete e 11 anos. MÉTODOS: Foram avaliadas 166 crianças de escolas públicas e privadas (90 meninas e 76 meninos) da cidade de Natal, no estado do Rio Grande do Norte. Foram coletados dados pessoais, antropométricos e perímetros torácicos por cirtometria. O teste t de Student não pareado e a análise de variância compararam o coeficiente respiratório xifoidiano entre os sexos e as idades, respectivamente. Diferenças no coeficiente respiratório axilar entre os sexos e as idades foram verificadas com os testes de Mann-Whitney e Kruskal-Wallis, respectivamente, com diferenças localizadas pelo teste post-hoc de Duncan. Coeficientes de correlação de Spearman e Pearson relacionaram variáveis independentes com os coeficientes avaliados. RESULTADOS: As médias das perimetrias axilar e xifoidiana foram 5,00±1,59 e 4,75±1,56cm, respectivamente. Observou-se baixa correlação, sem significância estatística, entre o coeficiente respiratório xifoidiano e as variáveis idade, sexo, peso, altura e índice de massa corpórea. O coeficiente respiratório axilar correlacionou-se com peso e altura. Foram encontradas diferenças no coeficiente respiratório axilar nas faixas etárias entre oito e dez anos (p=0,03) e 10 e 11 anos (p=0,02). CONCLUSÕES: Foram disponibilizados valores de referência de cirtometria torácica para crianças entre sete e 11 anos. Sexo, idade, peso, altura e índice de massa corpórea não influenciaram o coeficiente respiratório xifoidiano. O coeficiente respiratório axilar diferiu-se entre idades, a partir dos oito anos, sendo influenciado pelo peso e pela altura, independentemente do sexo.
Highlights
Evidence-based practice is currently a reality in healthcare
Thoracoabdominal mobility and/or expansibility provide information on the presence or absence of thoraco-pulmonary stiffness, which is often related to respiratory diseases[3]. This method has been used in individuals with respiratory diseases, in the postoperative period, and before and after therapeutic interventions[4], since thoracic mobility, among other evaluation criteria of lung function, can be considered an important parameter for diagnosis, follow-up of disease evolution, and assessment of the efficacy of the treatment proposed for different clinical conditions that present with respiratory impairment[5]
The present study aims to provide reference values for thoracic mobility using thoracic cirtometry, and to evaluate the factors correlated with chest mobility in healthy Brazilian children aged 7 to 11 years from the city of Natal, state of Rio Grande do Norte, Brazil (Natal-RN)
Summary
Evidence-based practice is currently a reality in healthcare. It consists of developing a clinical assessment through quality tests and measurements, which enables the identification of the problem. Thoracic mobility is related to the integrity of respiratory muscles that assist in thoracic expansion and retraction[2] In clinical practice, this measurement is used with the aim of evaluating parameters such as chest width, lung volumes and capacities, pulmonary compliance, thoracoabd ominal mechanics, diaphragmatic function, muscle work, and dyspnea[1]. Thoracoabdominal mobility and/or expansibility provide information on the presence or absence of thoraco-pulmonary stiffness, which is often related to respiratory diseases[3] This method has been used in individuals with respiratory diseases, in the postoperative period, and before and after therapeutic interventions[4], since thoracic mobility, among other evaluation criteria of lung function, can be considered an important parameter for diagnosis, follow-up of disease evolution, and assessment of the efficacy of the treatment proposed for different clinical conditions that present with respiratory impairment[5]
