"People who regularly groom their pubic hair are 75% more likely to develop a sexually transmitted infection"

UPDATE: "People who regularly groom their pubic hair are 75% more likely to develop a sexually transmitted infection than non-groomers"

From the comment section:

I think that may be what we call mutual correlation to a third variable.

People who are not sexually active are less likely to bother with removing their pubes, since it's no one else's problem.

Scoop's note:

That comment is almost certainly correct, although the article seems to speculate otherwise. The correlation most likely means that people who have the most sex are most likely to contract sexually transmitted infections (which is pretty obvious), and are also most likely to groom their bodies (which is not completely obvious, but is probable). You would probably also find that people who buy the most condoms are most likely to have STI's, because people who don't have sex don't buy many condoms. That does not mean (obviously) that condoms cause STIs. This story is probably an excessively superficial summary of the actual research. If the researchers are any good at all, they have performed statistical tests to eliminate codependence from their conclusions.
