The present study examines whether physical activity level (hours per week) among children with and without asthma are associated with the prevalence of reported wheezing and whistling in the chest in the last 12 months. The data are based on a survey of school children, aged 7-16 years (n = 2188), in Oslo in 1994 that employed the ISAAC questionnaire. In children reporting asthma, wheezing and whistling in the chest in the last 12 months was less prevalent among inactive children (66.7%) compared to those who exercised (89.4%) (p = 0.05). The prevalence of wheeze also differed among inactive (4.4%) and active (8.8%) children not reporting asthma (p = 0.02). Positive associations between physical activity and wheezing and whistling in the chest remained present using multiple logistic regression analysis adjusting for sex, age and atopy. Children who are engaged in sports or exercise seem to report asthma symptoms differently than inactive children. These findings raise the question whether level of physical activity could affect some of the variability in reported asthma symptoms when such morbidity is measured as 'wheeze in last 12 months'.
本研究调查了患有和未患哮喘的儿童的身体活动水平（每周小时数）是否与过去12个月内报告的胸部喘息和哮鸣患病率相关。数据基于1994年在奥斯陆对2188名7至16岁学童进行的一项调查，该调查采用了国际儿童哮喘和过敏研究（ISAAC）问卷。在报告患有哮喘的儿童中，过去12个月内胸部出现喘息和哮鸣的情况在不活动的儿童中（66.7%）比运动的儿童中（89.4%）更为少见（p = 0.05）。在未报告患有哮喘的不活动（4.4%）和活动（8.8%）儿童中，喘息患病率也存在差异（p = 0.02）。在对性别、年龄和特应性进行调整的多因素logistic回归分析中，身体活动与胸部喘息和哮鸣之间的正相关关系依然存在。参与运动或锻炼的儿童报告哮喘症状的方式似乎与不活动的儿童不同。这些发现提出了一个问题，即当将哮喘发病率衡量为“过去12个月内的喘息”时，身体活动水平是否会影响报告的哮喘症状的某些变异性。
