This could also mean that women avoid getting married to men who are prone to "higher death, suicide, crime, and disease rates". For example, how many women would really get married to a hobo?
Yeah, selection bias. Not just shiftless hobos, either. As a man you're going to have a harder time finding a wife if you're sick or have unhealthy habits (like obesity or heavy drinking).
Edit: I expect the same is true for single women, too. I doubt single women live as long as their married counterparts on a statistical basis.
