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).
