NCT06420622

Brief Summary

The study investigates the genetic backgrounds of extreme childhood obesity (using saliva sample) and contains short online questionnaires on family history, phenotypical characteristics and hunger behavior. It is an observational study in a predefined cohort (subjects with data in CrescNet aged 0-18 with BMI measurement(s) above the 99.5th percentile). Recruitment will initially be from CrescNet data through the cooperating pediatric and adolescent medical institutions associated with these initiative of data collection in Germany.
