PHYSICAL ACTIVITY LEVEL IN ASTHMATIC ADOLESCENTS: CROSS-SECTIONAL POPULATION-BASED STUDY

ABSTRACT Objective: To assess the level of physical activity in asthmatics in comparison with non-asthmatics in a population study. Methods: Cross-sectional study with 13 to 14-year-old adolescents who participated in the International Study of Asthma and Allergies in Childhood (ISAAC). The subjects were classified into three groups: individuals with active asthma, individuals diagnosed with asthma, and respiratory asymptomatic individuals. To evaluate the level of physical activity, the International Physical Activity Questionnaire (IPAQ-short version) was used. The analysis consisted of comparing individuals with active asthma, diagnosed as asthmatic and asymptomatic, with a significance level of 5%. Results: The participants were 1,591 adolescents, of which 791 (49.7%) were male. There were 222 (14.0%) individuals with active asthma and 284 (17.8%) asthma diagnoses; 55% of the population were physically active. Adolescents diagnosed with asthma were more active than their non-asthmatic peers (64.4 versus 53.3%; p=0.001). Conclusions: Adolescents diagnosed with asthma were more physically active than their non-asthmatic peers.

摘要 研究目的：本研究旨在通过人群研究，对比哮喘患者与非哮喘人群的身体活动水平。研究方法：本研究为横断面研究，纳入参与国际儿童哮喘与过敏性疾病研究（International Study of Asthma and Allergies in Childhood, ISAAC）的13~14岁青少年作为研究对象。将研究对象分为三组：活动性哮喘患者、确诊哮喘患者以及呼吸道无症状者。采用国际身体活动问卷简版（International Physical Activity Questionnaire, IPAQ-short version）评估研究对象的身体活动水平。统计学分析以5%作为检验水准，对比三组研究对象的身体活动水平差异。研究结果：本研究共纳入1591名青少年，其中791名（49.7%）为男性。活动性哮喘患者共222例（占比14.0%），确诊哮喘患者共284例（占比17.8%）；总体人群中55%的研究对象身体活动充足。确诊哮喘的青少年较非哮喘同龄人群身体活动水平更高（64.4% vs 53.3%；p=0.001）。研究结论：确诊哮喘的青少年身体活动水平高于非哮喘同龄人群。
