BACKGROUND Most of the studies investigating the prevalence of asthma in various countries have focused on children below the age of 15 years or adults above the age of 18 years. There is limited knowledge concerning the prevalence of asthma in 16- to 18-year-old adolescents. Our objective was to study the prevalence of asthma and associated symptoms in 16- to 18-year-old adolescents in Saudi A...

It is not clear whether asymptomatic bronchial responsiveness is a risk factor for development of asthma. A cross-sectional study was conducted to determine the prevalence of asthma among schoolchildren from Barcelona (Spain). The association between respiratory symptoms and bronchial responsiveness to exercise was examined. For this study 3,033 schoolchildren aged 13-14 yrs were studied from t...

BACKGROUND The role of physical training in the management of children with exercise-induced asthma is controversial. A study was undertaken to determine whether a relationship could be found between the occurrence of exercise-induced asthma and the degree of cardiovascular fitness in asthmatic children. METHODS Twenty eight children aged 6-13 with mild to moderate asthma and dyspnoea during ...

Several calcium antagonists, each with significantly different chemical structures, have demonstrated variable attenuation of exercise-induced asthma. Quantitative comparisons have been hampered by differences in the intensity of challenge and the severity of the underlying disease between groups of patients. In 12 asthmatic adults with relatively severe exercise-induced asthma, we compared the...

Konig, P., and Godfrey, S. (1973). Archives of Disease in Childhood, 48, 513. Prevalence ofexercise-induced bronchial lability in families ofchildren with asthma. Exercise tests and skin tests were performed in 65 members of the families of 12 children with asthma. A positive response to skin and exercise challenge frequently, but not invariably, occurred together. Abnormal exercise-induced bro...

Methods In this cross sectional study were included 115 asthmatic children and adolescents 9 to 19 years old and their mothers. For the children, asthma severity, PA level and exercise induced bronchospasm (EIB) were evaluated. The mothers were investigated on their beliefs about PA in non-asthmatic and asthmatic children, if they imposed restrictions to their children PA, perception of exercis...

"If from running, gymnastic exercises, or any other work, the breathing becomes difficult, it is called Asthma (<XmJlCX)". Aretaeus the Cappodician; lst Century AD [1]. Exercise-induced bronchoconstriction (EIB) was long ago recognized as a manifestation of asthma [1], and exercise-induced asthma (EIA) is a common presentation of childhood asthma. BACKER and ULRIK [2] reported that 16% of 494 h...

Exercise-induced bronchospasm (EIB) can represent a substantial barrier to physical activity. We present the cases of two patients with EIB, one with asthma, and one without asthma, who were evaluated at our primary care practice. The first case was a 44-year-old man with a history of seasonal allergic rhinitis but no asthma, who reported difficulty breathing when playing tennis. The second cas...
