Exercise-induced dyspnea is a problem among the general adolescent population

Abstract

Adolescents with undiagnosed exercise-induced dyspnea have respiratory symptoms and are affected in daily life but have the same level of physical activity as adolescents without exercise-induced respiratory symptoms.

Prevalence of exercise-induced bronchoconstriction and exercise-induced laryngeal obstruction in a general adolescent population

“…During 2011 all 12–13-year-old adolescents in the city of Uppsala (n=3838) received a questionnaire on exercise-induced respiratory problems 1. The adolescents were also asked to report exercise-induced respiratory symptoms by answering the following question: ‘Have you had any of the following symptoms more than once during or after physical exercise during the last 12 months; wheeze, chest tightness, cough, throat tightness, choking sensation, hoarseness or inspiratory stridor?’.…”

“…Exercise-induced dyspnoea was reported by 14% of Swedish adolescents1 and exercise-related wheezing was reported by 19% in the International Study of Asthma and Allergies 2. Although common, the reasons for exercise-induced respiratory symptoms have not been thoroughly investigated and are not well understood.…”

Influência dos polimorfismos no receptor beta 2 adrenérgico na presença de broncoespasmo induzido pelo exercício em adolescentes

“…O Índice de Massa Corporal (IMC) foi calculado pela fórmula IMC (kg/m2)=Massa corporal (kg)/Estatura2 (m). Essa variável foi convertida para IMC-escore Z, por meio do software WHO Anthroplus v.1.0.4 desenvolvido pela Organização Mundial da Saúde (OMS), classificado de acordo com os pontos de corte propostos pela OMS em 2006 17…”

“…Exercise-induced bronchospasm (EIB) is defined as temporary narrowing of the airways that occurs after strenuous exercise in up to 90% of asthmatic individuals1 and in almost 20% of individuals with no history of respiratory disease 2. The presence of excess weight can contribute to increased severity of EIB in asthmatics 3.…”

“…O broncoespasmo induzido pelo exercício (BIE) é definido como estreitamento transitório das vias aéreas que acontece logo após exercícios intensos em até 90% dos indivíduos asmáticos1 e em quase 20% das pessoas sem histórico de doenças respiratórias 2. A presença de excesso de peso pode contribuir para aumento da gravidade do BIE em asmático 3.…”
