Question: 1 / 400

Which of the following is a risk factor for placental abruption?

Increased age above 35

Smoking

Smoking is a well-established risk factor for placental abruption, which is the premature separation of the placenta from the uterine wall. The harmful chemicals in tobacco smoke can lead to vascular changes and reduce blood flow to the placenta, which may ultimately contribute to its detachment. Additionally, smoking is also associated with other adverse pregnancy outcomes, such as preterm birth and low birth weight, further highlighting its detrimental impact on maternal and fetal health.

While factors like increased maternal age, malnutrition, and low prenatal care visits may influence overall pregnancy health, they are not as directly linked to placental abruption as smoking is. Therefore, identifying smoking as a specific and significant risk factor for placental abruption is critical in prenatal care and counseling.
