Asthma control
The Asthma Control Test (ACT), validated for Brazilian Portuguese use, was used to assess the level of asthma control (12). The ACT has five questions regarding activity limitation, shortness of breath, and nighttime symptoms experienced over the last four weeks. Each question has five response options ranging from 1 (worst) to 5 (best). The ACT scores range from 0 (totally uncontrolled asthma) to 25 (totally controlled asthma), and scores ≥20 indicate controlled asthma (12).
