“…Table shows the results of the subgroup analyses for the prevalence of EIB in general population of children and adolescents. Seven studies with sample size less than 400 showed a pooled mean prevalence of 15% (95% CI: 11‐19%), compared with 9% (95% CI: 7‐10%) in 12 studies with sample size between 400 and 1000, and 8% (95% CI: 7‐9%) in 14 studies with sample size greater than 1000 ( P < 0.001 for heterogeneity between subgroups). The global mean prevalence of EIB was 8% (95% CI 7‐9%) and 9% (95% CI 8‐10%) in the post hoc sensitivity analyses, excluding seven studies with sample size less than 400 and two studies with “poor” study quality, respectively.…”

“…We found 64% of pectus patients reported dyspnea on exertion, a finding almost identical to Kelly's 63% in a prospective observational study of 327 pectus patients 34 . Prior studies in adolescents report an overall prevalence of dyspnea with exertion ranging from 7% to 14% suggesting individuals with pectus experience greater dyspnea symptoms than would be expected in the general population 35,36 . In our study, among the those reporting dyspnea on exertion nearly three-quarters had normal CPET, and dyspnea was not associated with a reduced VO 2 by multivariable linear regression modeling.…”

Pulmonary defects are reported in pectus excavatum but the physiological impact on exercise capacity is unclear. To test the hypothesis that pectus deformities are associated with a pulmonary impairment during exercise we performed a retrospective review on pectus patients in our center who completed a symptom questionnaire, cardiopulmonary exercise test, pulmonary function tests (PFT), and chest magnetic resonance imaging. Of 259 patients studied, dyspnea on exertion and chest pain was reported in 64% and 41% respectively. Peak oxygen uptake (VO2) was reduced in 30% and classified as mild in two-thirds. A pulmonary limitation during exercise was identified in less than 3%. Ventilatory limitations on PFT was found in 26% and classified as mild in 85%. Obstruction was the most common abnormal pattern (11%) followed by a nonspecific ventilatory limitation and restrictive pattern (7% each). There were no differences between patients with normal or abnormal PFT patterns for the anatomic degree of pectus malformation, VO2, or percentage reporting dyspnea or chest pain. Scatter plots demonstrated significant inverse relationships between severity of the pectus deformity with lung volumes on PFT and VO2 but no correlation between the severity of the pectus deformity and lung volumes during exercise. We conclude that resting lung volume measurements were associated with the anatomic degree of pectus severity but respiratory limitations during maximal exercise are uncommon and PFT patterns have poor correlation with symptomatology or VO2. These findings suggest non-respiratory causes are more likely for the high rates of dyspnea and reduced aerobic fitness reported in pectus.

“…In a study made with the aim to understand if school also could be a significant site of allergen exposure for children in terms of environmental factors, such as atmospheric conditions and the presence of allergens, both potentially predictive of exercise-induced symptoms during physical education, it was showed an effect of environmental factors, like humidity and barometric pressure, and environmental allergens, in particular it was observed of cat allergens, on the occurrence of the EIB and cough in schoolchildren (38). Atopy and upper airway diseases are also known to influence EIB.…”

Sport is an essential part of childhood, with precious and acknowledged positive health effects but the impact of exercise-induced bronchoconstriction (EIB) significantly reduces participation in physical activity. It is important to recognize EIB, differentiating EIB with or without asthma if the transient narrowing of the airways after exercise is associated with asthmatic symptoms or not, in the way to select the most appropriate treatment among the many treatment options available today. Therapy is prescribed based on symptoms severity but diagnosis of EIB is established by changes in lung function provoked by exercise evaluating by direct and indirect tests. Sometimes, in younger children it is difficult to obtain the registration of difference between the preexercise forced expiratory volume in the first second (FEV1) value and the lowest FEV1 value recorded within 30 min after exercise, defined as the gold standard, but interrupter resistance, in association with spirometry, has been showed to be a valid alternative in preschool age. Atopy is the main risk factor, as demonstrated by epidemiologic data showing that among the estimated pediatric population with EIB up to 40% of them have allergic rhinitis and 30% of these patients may develop adult asthma, according with atopic march. Adopting the right treatment and prevention, selecting sports with no marked hyperventilation and excessive cooling of the airways, children with EIB can be able to take part in physical activity like all others.

School environmental factors are predictive for exercise-induced symptoms in children

Abstract: This study showed an effect of cat allergen and environmental factors (humidity, air pressure) on the appearance of exercise related cough/bronchoconstriction during activity class in a natural environment at school in a large urban population of schoolchildren.
