This is just a shot in the dark but all I coud guess is that a person "knowing" they were an accident would be more then likely a person born to older parents. I am talking parents in the age range of late 40's and up. Now, I don't know but possibly these children of said parents might be more predisposed to certain illness that have been tracked back to these types of births. Maybe they were trying to keep from asking "were your parents old when they had you" which would also seem rather odd. Just a guess on my part so take it with a grain of salt.
