Since I'm a pilot, the US Federal Aviation Administration requires me to reveal every detail of my medical history under penalty of prison regardless of whether a condition affects my ability to pilot an airplane. At least the laws discourage anything embarrassing from making the papers, though it usually comes out anyway. Because of the laws, I won't get involved in medical data unless I'm indemnified. I have worked with people from a number of other countries and continents. I have not found any differences.
Engineering seems to be universal.
