Guidance

Parameter Case Report Form Response Options
Body mass index Body mass index as kg/m2

The body mass index is specified as a specific value (e.g. 18.14 kg/m2) in Observation.valueQuantity. The unit is fixed to the UCUM code #kg/m2.

​This profile of a FHIR Observation is derived from the vital-signs-base profile of the German Corona Consensus Dataset (GECCO).
