Bone size and body size adjustment

A context node for how body size, height, and bone size can shape areal BMD interpretation, especially in pediatric use.

What it is

Bone size and body size adjustment keeps height, body size, and areal BMD measurement mechanics near the interpretation layer.[1]

Why it matters

Areal BMD can be influenced by bone size, so small or delayed-growth bodies can make density comparisons look different from volumetric bone strength.[1]

What it affects

  • Pediatric densitometry guidance highlights adjustment for short stature or growth delay when interpreting Z-score context.[1]
  • Body-size context also reminds adult comparisons not to treat device output as a biology-only statement.[2]

Interpretation traps

  • BioConst does not perform size correction formulas or replace a clinician/lab report interpretation.[1]
