I don’t have “Health” on my iPad Air (latest gen).
I suspect that’s because iPads don’t have the health sensors and access to the AppleWatch the iPhone does. That’s likely why you won’t find that. It’s also there on iPhones for access from the lock screen for emergency purposes if you’re found non-responsive have been in an accident. People in an ER can find out necessary contact information and other health information that can help you from that health access.
