The asthma control test (ACT) is a validated tool for assessing control in asthmatic children aged 12 years and older. Using the ACT, we sought to assess asthma control and knowledge in London secondary school children.
Secondary schools in London, UK, participated in this study. Children with doctor-diagnosed asthma were invited to complete an online questionnaire that included the ACT and questions about asthma. Suboptimal asthma control was defined as an ACT score of ≤ 19 out of a maximum score of 25. Data are summarised as median and interquartile range (IQR), and were analysed by either Mann-Whitney test, or chi-square test. A p value of < 0.05 was considered significant.
A total of 799 children completed the questionnaire; 689 (86.2%) were included for analysis. Suboptimal asthma control was reported by 49.6% of students. Over a third (42.4%) of students prescribed a short-acting β2-agonist inhaler felt uncomfortable using it at school, and 29.2% (n = 173) reported not using this inhaler when wheezy. 56.4% (n = 220) of those with regular inhaled corticosteroids did not take them as prescribed, and 41.7% did not know what this inhaler was for. Suboptimal control was associated with a greater proportion of students reporting that they were 'somewhat', 'hardly' or 'not at all' comfortable using inhalers at school (52.7% vs 29.1%, p < 0.01) and outside school (22.8% vs. 14.8%, p < 0.01).
Suboptimal asthma control and poor asthma knowledge are common in London schoolchildren.
哮喘控制测试（ACT）是一种经过验证的工具，用于评估12岁及以上哮喘儿童的病情控制情况。我们使用ACT来评估伦敦中学生的哮喘控制情况和相关知识。
英国伦敦的中学参与了本研究。邀请医生诊断为哮喘的儿童完成一份在线问卷，其中包括ACT以及有关哮喘的问题。哮喘控制不佳定义为ACT得分在满分25分中≤19分。数据以中位数和四分位间距（IQR）进行汇总，并通过曼-惠特尼检验或卡方检验进行分析。p值<0.05被认为具有统计学意义。
共有799名儿童完成了问卷；689名（86.2%）纳入分析。49.6%的学生报告哮喘控制不佳。超过三分之一（42.4%）使用短效β2受体激动剂吸入器的学生在学校使用时感到不适，29.2%（n = 173）报告喘息时未使用该吸入器。56.4%（n = 220）规律使用吸入性糖皮质激素的学生未按医嘱用药，41.7%不知道该吸入器的用途。哮喘控制不佳与更大比例的学生报告在学校（52.7%对29.1%，p < 0.01）和校外（22.8%对14.8%，p < 0.01）使用吸入器时“有些”“几乎不”或“根本不”舒适有关。
哮喘控制不佳和哮喘知识匮乏在伦敦学童中很常见。
