Growth Reference
https://schema.aidops.org/vocab/growth-reference
The reference population used to derive z-scores and band classifications from anthropometric measurements. Different references produce different z-scores for the same raw measurement, so the reference must travel with the derived values.
Standard reference
WHO Child Growth Standards and Growth Reference (https://www.who.int/tools/child-growth-standards)
WHO publishes two references: the 2006 Child Growth Standards for children 0-59 months and the 2007 Growth Reference for school-age children and adolescents (5-19 years). The CDC 2000 Growth Charts and the earlier NCHS/WHO 1977 reference are still encountered in US and historical datasets.
Values
| Code | Label | Standard code | Definition |
|---|---|---|---|
who_2006 | WHO Child Growth Standards (2006) | Reference for children 0-59 months. The default for most humanitarian, national surveillance, and public-health anthropometry today. | |
who_2007 | WHO Growth Reference (2007) | Reference for school-age children and adolescents (5-19 years). Uses BMI-for-age rather than weight-for-height. | |
cdc_2000 | CDC 2000 Growth Charts | US CDC growth charts, widely used in the United States. Not interchangeable with the WHO 2006 standards: the same raw weight-for-height can classify differently under the two references. | |
nchs_1977 | NCHS/WHO 1977 Growth Reference | Legacy reference. Still present in historical datasets; superseded for active use by WHO 2006. | |
other | Other | A named reference not listed above. Use only when the actual reference is known and documented elsewhere on the record. |
