The aim of the COMO study is to analyze changes in (1) physical and (2) mental health, as well as (3) health behavior in children and adolescents during the years 2023, 2024, and 2025, following the COVID-19 pandemic, considering (4) socioecological contexts. The goal is to identify particularly vulnerable groups and thus create a (5) data foundation for targeted health promotion, prevention, and intervention approaches.

The COMO study is based on two existing population-based longitudinal studies (COPSY, MoMo-Corona-Study) as well as a new study sample. Children and adolescents (aged 4-17) from the new sample and their parents are invited to complete an online questionnaire in  2023, 2024 and 2025. The online survey includes for example questions on health behavior, mental and physical health, as well as socioecological variables.  In addition,  a subsample is invited to complete a digital motor performance test (online survey 2023) and/or to wear an accelerometer for 7 days to assess physical behaviour (online survey 2024). Participants who took part in all surveys of the MoMo-Corona study are asked  to participate in an in-depth, smartphone-based survey at the individual level.
