Asma inducida por ejercicio: Diferencias en la percepciónde síntomas entre pacientes pediátricos y sus padres / Exercise-induced asthma as perceived by pediatric patients and their parents

ABSTRACT

Background: Exercise is a frequent trigger of symptoms in asthmatic children and it worsens their quality of life. Aim: To compare the perception about exercise among asthmatic pediatric patients and their parents. Material and methods: Asthmatic patients with symptoms related to exercise, were tested with an exercise challenge test following the Tal protocol. Before testing, a questionnaire about symptoms triggered by exercise was answered by children and their parents. The data was analyzed with a Kappa correlation test. Results: Seventy five patients, aged 6 to 15 years, were studied. Forty one percent exercised less than one hour per week. Although 64% reported to experience respiratory difficulty and 80% cough during exertion, 87% were willing to perform more exercise. Forty percent of all patients had a positive challenge test for exercise-induced asthma. Correlation between patient's and parent's answers about the effect of physical activity exercise was low, with a kappa of 0.53. There was no correlation between exercise test and the answers to the questionnaire. Conclusions: Children with asthma frequently have exercise-associated symptoms and parental perception about this problem is very low.
