If you talk to your doctor about it they should be able to give you information on it. Most CF Accredited Clinics do yearly checks now to see if a person is or has developed CFRD.
It is definitely something worth keeping an eye on - but I say talk to your doc about reall in detail information.
If you do a search on the forums though and type in CFRD you should get a TON of posts about that topic. It is discussed frequently on here.
Take Care,
