“…In the present study, children in the lower socioeconomic class had the highest frequency of exercise induced bronchospasm, although this difference was not statistically significant. This finding is similar to what was reported by Kuti et al [22] in Nigeria. Other researchers have also reported similar findings [29,31].…”

“…With regards to the demographic characteristics of the respondents, the early adolescents (age 10-13 years) had a significantly higher frequency of EIB than older children. This is similar to the studies of Onazi et al [5] and Kuti et al [22] who both reported a higher prevalence of EIB in the early adolescent age group; 10-14 and 11-13 years respectively. This finding may be explained by the fact that asthma and related disorders have been observed to be commoner during early puberty, and this is particular so in girls; this is because of the changes in level of female hormones during this period [23].…”

Introduction: Exercise-induced bronchospasm (EIB) is a transient narrowing of the airway that usually occurs shortly after exercise. It occurs commonly in people with asthma; however EIB has also been reported in individuals without clinical asthma. The study aimed to determine the prevalence and factors associated with EIB among secondary school students. Methods: It was a descriptive cross-sectional school-based study involving secondary school students aged between 10 and 17 years without previous history of asthma. Subjects undertook a six-minute running test, spirometry was done and the best of three FEV 1 readings were obtained pre-exercise, at 5, 10, 15 and 30 minutes post exercise. The diagnosis of EIB was made when there was a decrease in FEV 1 of ≥10% from baseline after exercise. Results: Of the 265participants studied, 34 (12.8%) had EIB at 5 minutes post exercise. EIB was significantly more in the 10-13 years age group (χ2 = 18.416, p = <0.001), there was no significant gender difference. The presence of allergic (vernal) conjunctivitis and rhinitis were both significantly associated with the development of EIB (χ2 = 13.574, p < 0.001 and 0.011 respectively). There was no significant association with previous history of wheeze and exposure to indoor air pollution such as cooking with biomass fuel and parental cigarette smoking. Conclusion: EIB exist among non-asthmatic school children, and it is more frequent in the early adolescent age-group. Students with allergic conjunctivitis and rhinitis are more likely to manifest exercise induced bronchospasm.

“…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.…”

Exercise-induced bronchoconstriction (EIB) can occur in individuals with and without asthma, and is prevalent among athletes of all levels. In patients with asthma, symptoms of EIB significantly increase the proportion reporting feelings of fearfulness, frustration, isolation, depression and embarrassment compared with those without symptoms. EIB can also prevent patients with asthma from participating in exercise and negatively impact their quality of life. Diagnosis of EIB is based on symptoms and spirometry or bronchial provocation tests; owing to low awareness of EIB and lack of simple, standardised diagnostic methods, under-diagnosis and mis-diagnosis of EIB are common. To improve the rates of diagnosis of EIB in primary care, validated and widely accepted symptom-based questionnaires are needed that can accurately replicate the current diagnostic standards (forced expiratory volume in 1 s reductions observed following exercise or bronchoprovocation challenge) in patients with and without asthma. In patients without asthma, EIB can be managed by various non-pharmacological methods and the use of pre-exercise short-acting β2-agonists (SABAs). In patients with asthma, EIB is often associated with poor asthma control but can also occur in individuals who have good control when not exercising. Inhaled corticosteroids are recommended when asthma control is suboptimal; however, pre-exercise SABAs are also widely used and are recommended as the first-line therapy. This review describes the burden, key features, diagnosis and current treatment approaches for EIB in patients with and without asthma and serves as a call to action for family physicians to be aware of EIB and consider it as a potential diagnosis.

Prevalence and factors associated with exercise-induced bronchospasm among rural school children in Ilesa, Nigeria

Abstract: The prevalence of EIB among rural schoolchildren in Ilesa was 9.2%. EIB was associated with the history of allergies and wheeze and presence of household poultry birds. We recommend routine screening of these children for early diagnosis and good asthma symptom control.
