A positive history of maternal mood or anxiety disorder was associated with a 2.12-fold increased risk of preeclampsia after adjustment for age, race/ethnicity, and pre-pregnancy body mass index (95% CI 1.02-4.45). The risk of preeclampsia appeared to be more strongly related with maternal mood or anxiety disorders first diagnosed during the index pregnancy (adjusted RR = 3.64; 95% CI 1.13-11.68). The corresponding RR for maternal mood and anxiety disorders diagnosed before pregnancy was 1.73 (95% CI 0.71-4.20)...
Okay, now *this* confirms a lot of our speculation. Being a nervous anxious person makes you at higher risk for preeclampsia, and diagnosed anxiety first diagnosed during pregnancy makes that pregnancy more than three and a half times more likely to develop it. Which is 5%x3.64= 18.2%.
Which makes it *much* more likely that if pregnancy makes you anxious, it's not the anxiety causing the PE -- it's the preeclampsia causing the anxiety.
