I think its important to note the distintion between those who deliver prematurely due to preeclampsia vs. preterm labor. Lots of things are attributed to premature birth - for the mother and research on preemies - when they really mean those who have gone through preterm labor (which includes, apparently, lots and lots of hormonal changes). This article is great because it actually lists preeclampsia separate. Wish others have as well...
