Since 2001 the International Olympic Committee-Medical Commission (IOC-MC) has required athletes using inhaled beta2 agonists to provide clinical evidence of their asthmatic condition. The aim of this study was to compare the reported prevalence of asthma at the 2000 and 2004 Olympic Games in the Great British Olympic team (Team GB).
Following local ethics committee approval, 271 athletes (165 men) from the 2004 Team GB volunteered and provided written informed consent. An athlete was confirmed asthmatic if he or she had a positive bronchoprovocation or bronchodilator test as defined by the IOC-MC. Pre-Olympic medical forms from the 2000 Team GB were also examined to establish the prevalence of asthma among the members of Team GB at the 2000 Olympic Games.
The prevalence of asthma in the two teams at the 2000 and 2004 Olympic Games was similar (21.2% and 20.7%, respectively). In the 2004 Olympic Games 13 of 62 athletes (21.0%) with a previous diagnosis of asthma tested negative. A further seven with no previous diagnosis of asthma tested positive.
The prevalence of asthma within Team GB remained unchanged between 2000 and 2004. The IOC-MC requirement that asthmatic athletes must submit documented evidence of asthma has highlighted that 13 (21.0%) previously diagnosed as asthmatic failed to demonstrate evidence of asthma while seven athletes with no previous history or diagnosis of asthma tested positive. Screening for asthma within elite athletic populations using bronchoprovocation challenges appears warranted to assist athletes in preparing more effectively for major sporting events.
自2001年以来，国际奥委会医学委员会（IOC-MC）要求使用吸入性β2激动剂的运动员提供其哮喘病情的临床证据。本研究的目的是比较2000年和2004年英国奥运代表队（英国队）中报告的哮喘患病率。
经当地伦理委员会批准，2004年英国队的271名运动员（165名男性）自愿参与并提供了书面知情同意书。如果运动员的支气管激发试验或支气管扩张试验呈阳性（按照IOC-MC的定义），则被确认为哮喘患者。还检查了2000年英国队的赛前医疗表格，以确定2000年奥运会英国队队员中哮喘的患病率。
2000年和2004年奥运会上两队的哮喘患病率相似（分别为21.2%和20.7%）。在2004年奥运会上，62名先前被诊断为哮喘的运动员中有13名（21.0%）检测呈阴性。另外7名先前未被诊断为哮喘的运动员检测呈阳性。
2000年至2004年期间，英国队的哮喘患病率保持不变。IOC-MC要求哮喘运动员必须提交哮喘的书面证明，这凸显出13名（21.0%）先前被诊断为哮喘的运动员未能证明哮喘证据，而7名先前无哮喘病史或诊断的运动员检测呈阳性。在精英运动员群体中使用支气管激发试验筛查哮喘似乎有必要，以帮助运动员更有效地为重大体育赛事做准备。
