Screening for Preeclampsia: US Preventive Services Task Force Recommendation Statement

摘要

Approximately 4% of pregnancies in the United States are affected by preeclampsia, defined as new-onset hypertension (or worsening hypertension in patients with existing hypertension) after 20 weeks' gestation, combined with either new-onset proteinuria or other symptoms involving multiple organ systems. This disorder is associated with poor maternal and fetal outcomes, including maternal mortality, maternal stroke, low birth weight, and stillbirth. African American women are affected by preeclampsia at a higher rate than are white women and also have higher fatality rates related to preeclampsia, which may be due to unequal access to adequate care.
