CDC Study Links Smoking in Early Pregnancy to Increased Risk of Heart Defects

Maternal smoking during the first three months of pregnancy correlates with a heightened risk of specific congenital heart defects in infants, according to a study released by the Centers for Disease Control and Prevention (CDC). Researchers found that women who smoked cigarettes during this period showed a 20 to 70 percent increased probability of giving birth to a child with such defects.

The CDC study examined the relationship between smoking and various types of heart malformations. The study emphasizes that not all congenital heart defects manifested the same increases in risk.

Congenital heart defects are structural abnormalities of the heart present at birth. These defects can range in severity, sometimes requiring surgery or lifelong medical care. The CDC continues to investigate factors that contribute to these conditions.

Researchers at the CDC encourage women who are pregnant or planning to become pregnant to abstain from smoking. They also recommend consulting with healthcare providers on strategies to quit smoking and for further information regarding prenatal health.
