Asthma is a multifactorial chronic respiratory disease resulting from both genetic and environmental factors. Asthma control is the ultimate goal of asthma management. Asthma control is assessed primarily by clinical evaluation. There are several easy and accessible methods for assessing asthma control, such as the ACT and the ACQ. We present a retrospective and comparative study, including 80 patients seen in allergology consultations at the respiratory diseases department of the Hôpital 20 aout in Casablanca over a period extending from January 2020 to October 2022. The results are compared with those of a previous study carried out in the same department in 2019, which enrolled 173 patients. Patients are divided into two groups. The aim of this study is to determine the factors associated with asthma non-control and to analyze the evolution of predictive factors of asthma non-control in asthmatic patients seen at the respiratory diseases department of the August 20 Hospital in Casablanca.
