Abstract
Objectives: This study was designed to evaluate bone mineral density (BMD) and to set a standardized pediatric normative database for BMD in a representative sample of healthy Egyptian females.
Methods: Twenty healthy females aged between 10 to 11 years were evaluated for weight, height, body mass index (BMI), calcium intake, sunlight exposure, physical activity, laboratory bone parameters and BMD. BMD was measured by bone densitometry (DXA) in lumbar spine and proximal femur regions and the total body.
Results: In general, whole body BMD was positively corelated with each of age, weight, height and BMI.
Conclusion: DXA parameters are affected by anthropometric measurement in the same age group.
Introduction:
Since its introduction in eighties, dual energy X-ray absorptiometry (DXA) has become a widely available and clinically useful tool in the evaluation and management of adult bone diseases. More recently its utilization in the pediatric population has rapidly increased. (Binkovitz and Henwood 2007)
The demand for bone mineral assessments in pediatrics has grown in the past decade. This trend likely reflects greater awareness of the importance of early bone health for osteoporosis prevention, as it is considered an adult problem with pediatric roots (Bachrach et al.,2007)
DXA is a preferred method for measuring BMD for many reasons as it is quick, easy, relatively safe requiring minimal radiation exposure, inexpensive compared to other assessment modalities (Guss et al., 2020)
