Many studies have shown an increased risk of developing exercise-induced bronchoconstriction among the athletic population, particularly at the elite level. Subjective methods for assessing exercise-induced bronchoconstriction such as surveys and questionnaires have been used but have resulted in an underestimation of the prevalence of airway dysfunction when compared with objective measurements. The aim of the present study was to compare the prevalence of exercise-induced bronchoconstriction among Tunisian elite athletes obtained using an objective method with that using a subjective method, and to discuss the possible causes and implications of the observed discrepancy. As the objective method we used spirometry before and after exercise and for the subjective approach we used a medical history questionnaire. All of the recruited 107 elite athletes responded to the questionnaire about respiratory symptoms and medical history and underwent a resting spirometry testing before and after exercise. Post-exercise spirometry revealed the presence of exercise-induced bronchoconstriction in 14 (13%) of the elite athletes, while only 1.8% reported having previously been diagnosed with asthma. In conclusion, our findings indicate that medical history-based diagnoses of exercise-induced bronchoconstriction lead to underestimations of true sufferers.
许多研究表明，在运动员群体中，尤其是精英运动员，患运动诱发支气管收缩的风险增加。已采用主观方法评估运动诱发支气管收缩，如调查和问卷，但与客观测量相比，这些方法导致气道功能障碍患病率被低估。本研究的目的是比较使用客观方法和主观方法得出的突尼斯精英运动员中运动诱发支气管收缩的患病率，并讨论观察到的差异的可能原因及影响。作为客观方法，我们在运动前后使用了肺活量测定法；作为主观方法，我们使用了病史问卷。所有招募的107名精英运动员都回答了有关呼吸道症状和病史的问卷，并在运动前后接受了静息肺活量测定测试。运动后肺活量测定显示，14名（13%）精英运动员存在运动诱发支气管收缩，而只有1.8%的人报告曾被诊断为哮喘。总之，我们的研究结果表明，基于病史对运动诱发支气管收缩的诊断会导致对真正患者的低估。
