* Car accidents, because we drive much more and are much more spread out than other countries.
* Drug overdoses, though other countries are starting to catch up to us there.
* Homicide, because of our gun policy and the universality of firearms (which also bears on our suicide stats).
* CVD.
That last item sounds like an indictment of the US health care system, but it isn't. If you break CVD out by state, northeastern states like Massachusetts have outcomes resembling the Nordics, and Mississippi has outcomes like a developing country. But the structure of the health care system is the same in both places.
