Sudden Infant Death Syndrome (SIDS) is the unexpected and unexplained death of an infant under the age of one. SIDS is one of the leading causes of infant mortality, with an estimated 3,500 cases each year in the United States alone.
Despite decades of research, the exact cause of SIDS is still unknown. However, research has identified several risk factors that increase the likelihood of SIDS.
Preventative Measures
The most important preventative measure for reducing the risk of SIDS is placing infants on their backs to sleep. This is known as the “back-to-sleep” position, and it has been shown to reduce the risk of SIDS by 50%.
Other preventative measures include avoiding smoking during pregnancy and after birth, breastfeeding, and using a firm sleep surface such as a bassinet or crib with a tightly fitted sheet.
Environmental Risk Factors
Research has identified several environmental risk factors that increase the likelihood of SIDS. These include sleeping on soft surfaces such as couches or pillows, sleeping in the same bed as the parents, and sleeping in an overheated room.
Infants who are exposed to secondhand smoke also have an increased risk of SIDS.
Maternal Risk Factors
Maternal risk factors can also contribute to SIDS. One of the most significant risk factors is smoking during pregnancy. Infants whose mothers smoke during pregnancy are three times more likely to die from SIDS than infants whose mothers do not smoke.
Other maternal risk factors include drug or alcohol use during pregnancy, poor prenatal care, and premature birth.
Infant Care Risk Factors
There are several infant care-related risk factors associated with SIDS. These include placing infants to sleep on their stomachs or sides, using soft bedding or loose objects in the crib, and overbundling infants.

Infants who are born with a low birth weight or who have siblings who died from SIDS may also be at increased risk.
Genetic Risk Factors
While the exact cause of SIDS is unknown, research suggests that genetics may play a role. Studies have shown that infants who die from SIDS are more likely to have abnormalities in their brain stem, which controls breathing and heart rate.
There may also be genetic factors that contribute to certain infant sleep patterns or behaviors that increase the likelihood of SIDS.
Prevention and Education
While there is no guaranteed way to prevent SIDS, parents and caregivers can take steps to reduce the risk.
These include following safe sleep practices, practicing good prenatal care, avoiding smoking and secondhand smoke, and seeking medical care promptly if an infant shows signs of illness or distress.
Education is also key in preventing SIDS. Parents and caregivers should be educated on safe sleep practices for infants, including the importance of placing infants on their backs to sleep and avoiding loose bedding or objects in the crib.
Education should also include information on maternal risk factors and the importance of seeking prenatal care.
Conclusion
Sudden Infant Death Syndrome is a tragic and devastating event that can occur in seemingly healthy infants. While the exact cause of SIDS is unknown, research has identified several risk factors that increase the likelihood of SIDS.
By following safe sleep practices, practicing good prenatal care, and seeking medical care promptly, parents and caregivers can reduce the risk of SIDS and protect the health and wellbeing of their infants.
