Smoking Can Cause Clefts
As part of National Cleft and Craniofacial Awareness and Prevention Month, CDC urges women to quit smoking before pregnancy to reduce the risk of clefts of the lip or palate in babies. For free help quitting, call 1-800-QUIT-NOW (1-800-784-8669).
Although we don't know the causes of most orofacial clefts (clefts of the lip or palate) in babies, the 2014 Surgeon General's Report confirmed that smoking in early pregnancy can cause orofacial clefts in babies. This highlights an important prevention opportunity to improve the health of babies.1 Research has shown that about 6% of orofacial clefts in the United States are caused by smoking during early pregnancy. This means that over 400 babies could be born without orofacial clefts each year in the United States if women did not smoke early in pregnancy. Because these conditions often require numerous surgeries for repair, preventing orofacial clefts caused by smoking could save an estimated $40 million in healthcare costs each year for children up to age 10 years.2 Orofacial cleft defects happen very early in pregnancy, so quitting smoking before becoming pregnant is best.
Other Health Concerns
Most people know that smoking leads to cancer, heart disease, and other major health problems. However, women who smoke during pregnancy place themselves – and their unborn babies – at risk for even more health problems. Some of the dangers of smoking during pregnancy include premature birth, certain birth defects (like cleft lip and/or cleft palate and possibly some heart defects), and Sudden Infant Death Syndrome (SIDS). Even being around cigarette smoke puts a woman and her baby at risk for health problems.
Quitting smoking before becoming pregnant is best. But for women who are already pregnant, it is never "too late" to quit smoking. Quitting after becoming pregnant can still help protect against some health problems, such as the baby being born at a low birth weight (less than 5 ½ pounds).
Quit for Good
It is important to quit smoking for good. Some women might think it is safe to start smoking again after their baby is born, but their babies are not out of harm's way. Babies who are around cigarette smoke have weaker lungs than babies who aren't around cigarette smoke. They are also more likely to have other health problems, such as infections and frequent asthma attacks. Being around cigarette smoke can also increase the risk of SIDS.
