2 Methods
Studies published from November 2021 to February 2022 were identified
from PubMed® and Google Scholar databases using the
search terms ‘lockdown’, ‘COVID-19’, ‘asthma morbidity’, ‘asthma
control’, ‘asthma exacerbations, ‘behavioural changes’, ‘treatment
compliance’, ’pollution’ and ‘respiratory viral infections’. Studies
were selected if the target population was asthmatic children and the
outcomes were changes in morbidity and control, or changes in any
behaviour affecting their exposure to asthma triggers, during the
COVID-19 lockdown periods. Studies observing alterations in pollution
and implementation of restrictive measures were also included.
