Previous issue date: 2018-03-14 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Introduction: Asthma is a chronic respiratory disease of high prevalence in the child
population. Its diagnosis and correct treatment are essential so that the patient does not
move away from their routine activities. For this population, guided physical activity
can help decrease the symptoms of the disease, improve cardiorespiratory fitness,
reduce fat levels and increase muscle mass, decrease school absenteeism levels, and
raise quality of life scores. Objective: To evaluate and correlate levels of physical
activity with the pulmonary function of children diagnosed with asthma at school.
Methods: This study was accomplished out in two phases, in schoolchildren from Porto
Alegre / RS, from 8 to 16 years old. In the phase I (transversal) the sample was
characterized, being applied to the responsible ones of the students a questionnaire of
diagnosis of the asthma, following the standards of the international study "The
International Study of Asthma and Allergies in Childhood - ISAAC". In phase II (casecontrol)
after the characterization and identification of the asthma and control groups
(healthy) the anthropometry, physical activity levels and pulmonary function
(spirometry) were evaluated. For the purposes of statistical analysis, the descriptive and
categorical variables were presented by absolute and relative frequencies. The
descriptions of the continuous variables were presented through mean and standard
deviation (SD). For comparison between groups, the values were analyzed using the
chi-square test and the Pearson test correlations, with a significance value at p<0.05.
Results: A total of 605 students participated in the study, of which 290 were children
with clinical diagnosis of asthma and 315 were classified as controls. Of the total, 280
(47.3%) male children, with a mean age of 11.0?2.3 years. The categorical spirometric
values showed differences in the classifications of airway obstruction levels between
asthma and control groups (p 0.005), and the response to bronchodilator use >12% for
FEV1/FVC (p=0.023). The values of pulmonary function, anthropometric measurements
and physical activity levels were significantly different for spirometric values, showing
differences in pre-FEV1 and FEV1/FVC, p=0.008 and p<0.001, respectively)
(FEV1/FVC, p=0.003), for the anthropometric values, only the RCE variable presented
a modest difference (p=0.048), not being different for the means of physical activity or
risk of physical inactivity idle time in front of screens. In the correlation evaluation,
these results show a low correlation between the time spent in physical activities for the
FEV1 variables [R2=0.13; p=0.012] and FVC [R2 0.12; p=0.035]) for the asthma group,
at the time after bronchodilator use. Conclusion: The study shows differences in
spirometric volumes, especially after bronchodilator application, indicating obstructive
disorders in asthmatic children. At the same time, it shows a low relation between
anthropometric values and levels of physical activity with the pulmonary function of
school children. / Introdu??o: A asma ? uma doen?a cr?nica respirat?ria de elevada preval?ncia na
popula??o infantil. Seu diagn?stico e tratamento correto s?o imprescind?veis para que o
paciente n?o se afaste das suas atividades rotineiras. Para esta popula??o, a atividade
f?sica orientada pode auxiliar na diminui??o dos sintomas da doen?a, na melhora do
condicionamento cardiorrespirat?rio, na diminui??o os n?veis de gordura e aumento da
massa muscular, na diminui??o dos n?veis de absente?smo escolar, elevando os escores
da qualidade de vida. Objetivo: Avaliar e correlacionar os n?veis de atividade f?sica
com a fun??o pulmonar de crian?as com diagn?stico de asma em fase escolar. M?todos:
Estudo realizado em duas fases, em escolares da rede p?blica de Porto Alegre/RS, de 8
a 16 anos. Na fase I (transversal) a amostra foi caracterizada, sendo aplicado aos
respons?veis pelos escolares um question?rio de diagn?stico da asma, seguindo os
padr?es do estudo internacional ?The International Study of Asthma and Allergies in
Childhood ? ISAAC?. J? na fase II (caso-controle) ap?s a caracteriza??o e identifica??o
dos grupos asma e controle (h?gidos) os desfechos de antropometria, n?veis de atividade
f?sica e fun??o pulmonar (espirometria) foram avaliados. Para fins de an?lise estat?stica,
as vari?veis descritivas e categ?ricas foram apresentadas por frequ?ncias absolutas e
relativas. As descri??es das vari?veis cont?nuas foram apresentadas atrav?s de m?dia e
desvio padr?o (DP). Para compara??o entre os grupos, os valores foram analisados
utilizando os testes de qui-quadrado e as correla??es pelo teste de Pearson, com um
valor de signific?ncia com p<0,05. Resultados: Participaram do estudo 605 escolares,
sendo 290 crian?as com diagn?stico cl?nico de asma e 315 classificadas como controle.
Do total, 280 (47,3%) crian?as do sexo masculino, com idade m?dia de 11,0?2,3 anos.
Os valores espirom?tricos categ?ricos demonstram diferen?as nas classifica??es dos
n?veis de obstru??o das vias a?reas entre grupos asma e controle (p=0,005), al?m da
resposta ao uso de broncodilatador >12% para o VEF1/CVF (p=0,023). J? para as
vari?veis de escores cont?nuas os valores de fun??o pulmonar, medidas antropom?tricas
e n?veis de atividades f?sicas, houve diferen?as para os valores espirom?tricos,
demonstrando diferen?as nos volumes pr? (VEF1 e VEF1/CVF, p=0,008 e p=<0,001,
respectivamente), bem como nos volumes p?s (VEF1/CVF, p=0,003), para os valores
antropom?tricos, apenas a vari?vel RCE apresentou uma diferen?a modesta (p=0,048),
n?o sendo diferente para as m?dias de atividade f?sica ou risco de inatividade f?sica por
tempo ?cio na frente de telas. Na avalia??o da correla??o tais resultados, demonstram
haver baixa correla??o entre o tempo gasto em atividades f?sicas para as vari?veis VEF1
[R2=0,13; p=0,012] e CVF [R2=0,12; p=0,035]) para o grupo asma, no momento p?s
uso de broncodilatador. Conclus?o: O estudo demonstra existir diferen?as nos volumes
espirom?tricos, principalmente ap?s a aplica??o de broncodilatador, indicando
dist?rbios obstrutivos em crian?as asm?ticas. Ao mesmo tempo, demonstra baixa
rela??o entre valores antropom?tricos e n?veis de atividade f?sica com a fun??o
pulmonar de crian?as em fase escolar.
