Could be interesting. And I agree with the relevance of BMI in the outcome of a covid infection.
But I do think we need to ask a few questions on the purpose of adding it to Coronastatus specifically.
Does BMI differ very much with the township/postcode someone lives in? As opposed to country?
Does knowing BMI help map the spread and possible future outbreaks?
Will there be a significant lowering of filled out forms due to this being a hard to fill out question (apart from possibly confronting). And thus having a negative NET impact on mapping covid spread?
With recent focus on obesity, please include BMI in self report
