Preeclampsia in a previous pregnancy is the biggest risk factor for developing preeclampsia.[1] Use of assisted reproduction technology (e.g., in vitro fertilization) is also a risk factor; however, this may be confounded by advanced maternal age because older parents are more likely to use assisted reproduction technology. Some additional risk factors for preeclampsia are similar to the risk factors for cardiovascular disease, such as pregestational diabetes, high blood pressure, and a BMI over 30.
