Design outcomes

Primary

MeasureTime frame
The primary objective is the molecular biological, immunological, and genetic characterization of the biological samples obtained after discharge from the hospital until the age of five in order to identify risk markers for better early detection and/or to develop more targeted therapeutic strategies for children born at risk. The child's developmental status, the psychosocial environment of the child and parents, and parent-child interactions are also recorded using questionnaires. Data collection ends once a case number of n=500 (main group, premature infants) and n=200 (reference group, full-term infants after high-risk birth) children has been reached. The study will end 10 years after the last patient has been included in the study in order to allow for all necessary analyses and evaluations. The number of participants and the end date of the study will be recorded by the UOL trust agency, which monitors the consent and pseudonymization of participants.
