Background to preeclampsia
Prevalence
PE develops in 2-5% of pregnancies. The rate depends on the demographic characteristics of the population under investigation. For example in Black women the rate is 2-3 times higher than in White women.
In one third of the cases the condition leads to delivery at <37 weeks’ gestation (preterm PE) and in two thirds delivery occurs at ≥37 weeks (term PE)
