I was a Health and Society major...aka Public Health (although Rochester will insist to you that Health and Society is different than just Public Health because of a greater focus on all of society or something).
It's interdisciplinary but I don't think it really included the natural sciences. You can take history courses, anthropology courses, psychology courses, sociology courses, philosophy courses towards the major. But obviously most of these would relate to healthcare somehow (like medical ethics would be a philosophy course), and the ones that didn't relate as much are mostly there so you can take ones that relate to medicine (so like, you'd take regular ethics and it'd count towards the major). And the history classes would focus on western medicine, american medicine, etc. And anthropology would be more like, medical anthropology.
Good major but I wouldn't get into it if you weren't sure you were going to go to medical school or it's damned hard to get a job, lol. (by job I mean one that pays you in something other than skittles and twizzlers)
