The questionnaire, it is stated, is the result of a collaboration between the NHS website, Public Health England, UCL and the British Heart Foundation.
One obvious concern there is no clear definition of “heart age” alongside the questionnaire with the result that quite a few people have the impression that if they have a heart age of, say, 80 when they are actually 70, that that means that their heart is in the same state as that of an eighty year old. However, that is not the case.
The purpose of the questionnaire is plainly a positive one - to motivate people to make lifestyle changes to improve their heart health, but it seems to me that the absence of a clear definition people many people will be made anxious and/or lack confidence in the reliability questionnaire.
If there are any doctors or medical professionals reading this (or anyone from BHF) perhaps they could clarify/ validate the concept of “heart age”?
