Pregnant women at risk for developing preeclampsia should take low-dose aspirin daily to reduce their chance of developing the disorder according to new recommendations by the U.S. Preventive Services Task Force (USPSTF).
The USPSTF recommends low-dose aspirin (81 mg/day) preventive medication after 12 weeks’ gestation in women who are at high risk for preeclampsia.
Women at high risk include:
- Prior preeclampsia, especially when accompanied by an adverse outcome
- Multiple gestation pregnancy
- Chronic hypertension
- Type 1 or 2 diabetes
- Renal disease
- Autoimmune disease (i.e., systemic lupus erythematous, antiphospholipid syndrome)
In addition The U.S. Preventive Services Task Force (USPSTF) recommends women with more than one moderate risk factor for pre-eclampsia should to take 81 mg of aspirin daily after 12 weeks of gestation
Moderate risk factors include:
- Nulliparity (first pregnancy)
- Obesity (i.e., body mass index >30 kg/m2)
- Family history of preeclampsia (i.e., mother, sister)
- Sociodemographic characteristics (i.e., African American race, low socioeconomic status)
- Age ≥35 years
- Personal history factors (e.g., low birth weight or small for gestational age, previous adverse pregnancy outcome, >10-year pregnancy interval)
The USPSTF recommendations are similar to recommendation given by the National Institute for Health and Clinical Excellence (NICE) in previous years.
