You asked

​​Please could you let me have any data you may have for what ever date range you can on the average BMI of Covid deaths

We said

Thank you for your request.

Our mortality data is taken from the information provided on death certificates.

The death certificate used in England and Wales is compatible with that recommended by WHO. It is set out in two parts. Part I gives the condition or sequence of conditions leading directly to death, while Part II gives details of any associated conditions that contributed to the death but are not part of the causal sequence.

BMI is not recorded as part of the cause of death, therefore we do not hold the data you have requested.

Public Health England (PHE) may be better placed to answer this query. They can be contacted via email at wn_coronavirus@phe.gov.uk.
