- Body Measures
CDC/NCHS documentation supports continuity of the core NHANES anthropometry protocol across Continuous NHANES. Indexed differences for standing height are limited to dataset context and documentation wording, not a confirmed measurement discontinuity.
Evidence provenance: CDC/NCHS source-confirmed evidence · Praxis deterministic adjudication
Evidence signals: source-stated
Praxis harmonization actions
- Pool standing height across calibrated cycles without a method adjustment when no substantive variable-level change is present. Preserve age eligibility and relevant measurement comment-code exclusions.
