Summary
This study found that body weight is a strong predictor of lumbar spine bone mineral density in children aged 5-11. A specific equation using weight can estimate bone density in healthy youth.
Area of Science:
- Pediatrics
- Orthopedics
- Radiology
Background:
- Bone mineral density (BMD) is crucial for skeletal health.
- Understanding pediatric BMD development is essential for identifying potential issues early.
- Factors influencing BMD in children require further investigation.
Purpose of the Study:
- To assess the relationship between anthropometric measurements and lumbar spine bone mineral density in healthy children.
- To develop a predictive model for bone mineral density based on easily measurable parameters.
Main Methods:
- Dual photon absorptiometry was used to measure bone mineral density at the L2-L4 lumbar spine in 184 healthy children (aged 5-11.99 years).
- Measurements included weight, height, age, triceps skinfold thickness, and midarm circumference.
- Statistical analysis involved correlation and regression modeling.
Main Results:
- Weight, height, and age showed significant correlations with lumbar spine bone mineral density.
- A quadratic regression equation incorporating body weight provided the best model for predicting bone mineral density: BMD = 0.3209 + 0.0168(weight) - 0.0001(weight²).
Conclusions:
- Body weight is a key determinant of lumbar spine bone mineral density in healthy children within the studied age range.
- The derived regression equation offers a practical tool for estimating bone mineral density in pediatric populations.
- Further research can explore the application of this model in diverse pediatric groups.
