Tongue ultrasound for children and teens with obesity

Standardized Tongue Ultrasound Protocol for Tongue Characteristics in Children and Adolescents With Obesity After a 30-week Inpatient Weight Loss Program

Observational Haute Ecole Bruxelles-Brabant · NCT07370350

For children and teens with obesity enrolled in a 30-week inpatient weight-loss program, this project uses ultrasound to see if tongue size, fat content, and stiffness relate to body measurements and sleep apnea and change after the program.

What this trial studies

This is a prospective observational cohort of children and adolescents (6–18 years) with obesity who undergo standardized submental ultrasound at baseline and after a 30-week inpatient multidisciplinary weight-loss rehabilitation program. Ultrasound measures include tongue morphology, fat-related imaging biomarkers, and mechanical properties using shear-wave elastography. Anthropometric data and validated sleep-disordered breathing questionnaires are collected in parallel, and measurement reliability is tested. The study explores associations between ultrasound parameters, body measurements, and obstructive sleep apnea outcomes over time.

Who should consider this trial

Good fit: Children and adolescents aged 6–18 years with a diagnosis of obesity who are already enrolled in the Zeepreventorium 30-week inpatient weight-loss rehabilitation program and whose guardians provide consent.

Not a fit: People without obesity, those not enrolled in the Zeepreventorium inpatient program, or those with cervicocephalic conditions or other contraindications to ultrasound are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the project could provide a noninvasive ultrasound way to identify and monitor tongue features linked to sleep apnea risk and response to weight loss in young people.

How similar studies have performed: Some adult and small pediatric studies have shown promising correlations between tongue ultrasound/elastography and fat or sleep-disordered breathing, but longitudinal validation during pediatric weight-loss programs remains limited.
