Questionnaire about coronavirus (COVID-19) for parents and children

In March/April 2020, MoBa began sending out questionnaires about the coronavirus to all participants. As of November 2022, close to 60 questionnaires have been sent out to monitor the prevalence and burden of disease. Collection is still ongoing. Variables from these forms are now available on request, but they are not yet organized in a way that makes them suitable for disclosure. This makes the data demanding to extract, and it must therefore be noted that delivery can take a long time, especially in cases where a large number of variables are needed. We recommend starting with a smaller number of variables. Please contact the MoBa administration to receive an overview of the variables available.
