What this trial studies

This observational study explores the genetic backgrounds of extreme obesity in children by analyzing saliva samples and collecting data through online questionnaires regarding family history, phenotypical characteristics, and hunger behaviors. It targets children aged 0-18 with BMI measurements above the 99.5th percentile, utilizing existing data from the CrescNet registry. Pediatricians will identify eligible patients and facilitate telemedical consultations for informed consent and sample collection, ensuring a streamlined process for participation across Germany.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 0-18 with extreme obesity, defined as having a BMI above the 99.5th percentile.

Not a fit: Patients with known causes of severe early obesity may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a better understanding of the genetic factors contributing to extreme childhood obesity, potentially informing future treatments and interventions.

How similar studies have performed: While this approach is observational and builds on existing data, similar studies investigating genetic factors in obesity have shown promise in understanding the condition.
