Hello didier1976,
Apple always recommends not sharing an Apple ID with multiple people.
To my knowledge, unfortunately, there would be no way to transfer the data off of your Apple ID onto the newly created one.
One way to accomplish this would be going into the Health app and manually entering the data into the app and removing it from your Apple ID as you go. Obviously if you have a lot of data to move over this could become tedious.
Another potential option would be to create a new Apple ID for yourself and make the current one hers as then the data wouldn’t need to be transfer. However, I’m not familiar with your situation and what data you’d be loosing by creating a new Apple ID for yourself.
