Pediatric reference curves for multi-site quantitative ultrasound and its modulators

Area of Science:

• Pediatric bone health
• Quantitative ultrasound
• Skeletal development

Background:

• Peak bone mass accrual is critical during childhood and adolescence.
• Quantitative ultrasound (QUS) offers a non-invasive method for bone assessment.
• Establishing pediatric reference data is crucial for bone health evaluation.

Purpose of the Study:

• To establish pediatric reference curves for bone Speed of Sound (SOS) using multi-site quantitative ultrasound.
• To assess the feasibility of the Sunlight Omnisense 7000P for pediatric bone property assessment.
• To investigate correlations between SOS and demographic, anthropometric, lifestyle, and pubertal factors.

Main Methods:

• Analysis of 1085 healthy subjects aged 0-18 years (595 females, 490 males).
• Multi-site quantitative ultrasound measurements at the mid-shaft tibia and distal radius using Sunlight Omnisense 7000P.
• Collection of demographic, anthropometric, calcium intake, and physical activity data.

Main Results:

• Age-related SOS curves demonstrated distinct growth patterns in tibia and radius, with a pubertal growth spurt.
• Low physical activity was associated with lower Z-scores (P<0.05).
• Pre-menarche girls had significantly lower SOS than post-menarche girls (P<0.05); calcium intake showed no correlation.

Conclusions:

• The study successfully established pediatric reference curves for bone SOS using the Sunlight Omnisense 7000P.
• These reference curves support the use of this device for assessing pediatric bone properties.
• Further research in pediatric disease groups is recommended to support clinical evaluation and fracture risk prediction.
