What are some risk factors for placental abruption?

Placental abruption, the premature separation of the placenta from the uterine wall, has specific risk factors associated with its occurrence. Chronic hypertension is one of the most significant risk factors for placental abruption, as elevated blood pressure can compromise the placental blood supply and contribute to placental ischemia. Additionally, the risk of abruption increases with multiple gestations, which can create increased uterine distension and complications in placental attachment and vascularization.

In contrast, the other risks presented may not directly correlate with an increased likelihood of placental abruption. While obesity and diabetes can have various negative impacts on pregnancy, they are not recognized as primary risk factors for this specific condition. Similarly, advanced maternal age and low levels of PAPP-A (pregnancy-associated plasma protein A) can indicate other risks in pregnancy but do not specifically point to placental abruption as strongly as chronic hypertension and multiple gestation do.

Thus, chronic hypertension and multiple gestation are well-supported risk factors for placental abruption, rightfully making this the correct set of options related to the question of risk factors.
