Final answer:
Aspirin intake during Pregnancy may not be directly associated with lower birth weights and pre-term births, but it carries other risks to fetal health, especially when used in the third trimester.
Step-by-step explanation:
Taking aspirin during pregnancy can potentially lead to several adverse outcomes for the fetus. However, the impact mentioned in the student's question—lower birth weights and pre-term births—is not commonly associated with aspirin unless taken close to delivery. Aspirin belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs) and while it is often prescribed in low doses for certain conditions during pregnancy, its use is typically avoided, especially in the third trimester due to potential risks.
These risks include but are not limited to issues with fetal circulation and potential effects on the heart and lungs. Research indicates that other substances such as alcohol, nicotine, and various drugs can cause problems such as fetal alcohol spectrum disorders, low birth weight, pre-term birth, and sudden infant death syndrome (SIDS). Moreover, as it affects platelet function and may prolong bleeding, aspirin might increase the risk of hemorrhage in the newborn if ingested close to delivery.
