About this trial

This longitudinal observational study aims to validate ultrasound-based tongue markers related to tongue characteristics, including fat accumulation, morphologic and mechanical properties of the tongue in children and adolescents with obesity. Participants are assessed at baseline and after completion of a standardized 30-week inpatient weight-loss rehabilitation program at the Zeepreventorium (De Haan, Belgium). Tongue ultrasound parameters are examined in relation to anthropometric characteristics and obstructive sleep apnea condition.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Children and adolescents aged 6 to 18 years

Diagnosis of obesity

Already enrolled in the inpatient weight-loss rehabilitation program at the Zeepreventorium

Written informed consent from legal guardian and assent from the participant, following the legal requirements

Disqualifiers

Treatments tested in this trial

  • Submental ultrasound

    Other intervention

    Tongue ultrasound via a submental approach. This non-invasive, risk-free and harmless protocol will study both morphological and dynamic characteristics of the tongue.

Trial outcomes

Primary outcomes

1

Tongue stiffness

Tongue stiffness is measured by shear-wave elastography and expressed in kPa.

Time frame
at baseline and after 30-weeks weight loss program
2

Intraclass correlation coefficient, ICC

Intraclass correlation coefficient will be used to assess intra and inter-rater reliability of ultrasound markersUltrasound reliability and repeatability of tongue measurements will be assessed with intraclass correlation coefficients (ICC), along with their 95% confidence intervals. Each ultrasound measurement (tongue size and morphological parameters, echo intensity, stiffness, tissue attenuation imaging, tissue scatter distribution imaging, and fat fraction) in sagittal and coronal planes will be performed twice in fifteen participants by the principal investigator, with a 24-hour interval between examinations.

Time frame
Baseline

Secondary outcomes

1

Tongue thickness

Tongue thickness (expressed in cm) will be measured with ultrasound as the perpendicular distance from the deep fascia of the geniohyoid muscle to the highest lingual dorsum in the midsagittal plane

Time frame
at baseline and after 30 weeks weight loss program
2

Echo Intensity

Echo intensity will be measured with ImageJ / Fiji software (ImageJ, US NIH, Bethesda, USA) and refers to the mean value of pixels of an area, based on a grey scale between 0 (black) and 255 (white)

Time frame
at baseline and after a 30 weeks weight loss program
3

Tissue Attenuation Imaging index

Attenuation will be measured with ultrasound and depicts the quantitative measurement of ultrasound attenuation in tissues. It is expressed as an attenuation coefficient in dB/cm/MHz.

Time frame
at baseline and after a 30 weeks weight loss program
4

OSA-18 questionnaire

The Obstructive Sleep Apnea - 18 questionnaire is specific to obstructive sleep apnea in children and will be used for correlation analysis. Quality of life is assessed using the Obstructive Sleep Apnea - 18 Quality of Life Survey (OSA-18), a validated questionnaire comprising 18 items. Total scores range from 18 to 126, with higher scores indicating poorer quality of life and greater disease impact, and lower scores reflecting better outcomes.

Time frame
Baseline and after a 30-weeks weight loss program
