Statistics about Preeclampsia


advertisement

About statistics: This page presents a variety of statistics about Preeclampsia. The term 'prevalence' of Preeclampsia usually refers to the estimated population of people who are managing Preeclampsia at any given time. The term 'incidence' of Preeclampsia refers to the annual diagnosis rate, or the number of new cases of Preeclampsia diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.

Prevalence and incidence statistics for Preeclampsia: (see also prevalence and incidence page for Preeclampsia)
  Incidence (annual) of Preeclampsia: 146,320 cases (1998/NHLBI); about 5% of pregnancies.
  Incidence Rate: approx 1 in 1,858 or 0.05% or 146,320 people in USA [about data]
  Prevalance of Preeclampsia: Preeclampsia is the most common hypertensive disorder during pregnancy, affecting an estimated 5-8% of pregnant women annually in the United States, and has the greatest effect on maternal and infant outcome.1
  Incidence of Preeclampsia: High blood pressure problems occur in 6 percent to 8 percent of all pregnancies in the U.S., about 70 percent of which are first-time pregnancies. In 1998, more than 146,320 cases of preeclampsia alone were diagnosed.2
