They are much less likely to be breastfed, which can change IQ by 3 points.
Not to detract from your main point, but breast feeding is one of those topics which has been highly politicized and any weird claims like this should be taken with a grain of salt. I've read a study claiming what you say (can't find it now), here's another study claiming that isn't true. There are many more. Enough that I think you'd need to be an expert in the field in order to sort between them.
Usually though, when researchers start dickering over this sort of thing, what you can say for sure is that whatever the effect may be it isn't large enough or definitive enough to shut up all the people who are wrong about it. So at the end of the day it likely doesn't matter.
