Abstract
Background: Narratives about complaints in children and adolescents caused by wearing a mask are accumulating. There is, to date, no registry for side effects of masks.
Methods: At the University of Witten/Herdecke an online registry has been set up where parents, doctors, pedagogues and others can enter their observations. On 20.10.2020, 363 doctors were asked to make
entries and to make parents and teachers aware of the registry.
Results: By 26.10.2020 the registry had been used by 20,353 people. In this publication we report the results from the parents, who entered data on a total of 25,930 children. The average wearing time of the
mask was 270 minutes per day. Impairments caused by wearing the mask were reported by 68% of the parents. These included irritability (60%), headache (53%), dificulty concentrating (50%), less happiness
(49%), reluctance to go to school/kindergarten (44%), malaise (42%) impaired learning (38%) and
drowsiness or fatigue (37%).
Discussion: This world’s first registry for recording the effects of wearing masks in children is dedicated to a new research question. Bias with respect to preferential documentation of children who are particularly
severely affected or who are fundamentally critical of protective measures cannot be dismissed.
The frequency of the registry’s use and the spectrum of symptoms registryed indicate the importance of the
topic and call for representative surveys, randomized controlled trials with various masks and a renewed risk-benefit assessment for the vulnerable group of children: adults need to collecticely reect the
circumstances under which they would be willing to take a residual risk upon themselves in favor of enabling children to have a higher quality of life without having to wear a mask.
