- Dataset
- Body Measures
CDC/NCHS documentation supports continuity of the core NHANES anthropometry methods across Continuous NHANES, including waist circumference. Indexed differences for this variable are limited to dataset context and documentation wording, not a confirmed waist-measurement discontinuity.
Evidence provenance: CDC/NCHS source-confirmed evidence · Praxis deterministic adjudication
Evidence signals: source-stated
Praxis harmonization actions
- Pool waist circumference across calibrated cycles without a method adjustment when no substantive variable-level change is present. Preserve age eligibility, comment codes, and cycle-appropriate survey design requirements.
