Objective: To verify the frequency of risk factors for hearing loss in newborns and their possible associations with universal neonatal hearing screening results before and during the COVID-19 pandemic.

Methods: Historical cohort study with data analysis of newborns attended in a reference hearing health service of the Unified Health System (SUS) between January 2017 and December 2021.
