How many infants die from SIDS or are at risk for SIDS?

Data from the Centers for Disease Control and Prevention (CDC) estimate that about 3,000 infants died from a sudden unexpected infant death, with more than 1 in 3 dying from sudden infant death syndrome (SIDS) in 2022 (the most recent year for which data are available).1

What factors increase the risk of SIDS?

Currently, there is no known way to prevent SIDS, but there are ways to reduce the risk. Several factors present during pregnancy, at birth, and throughout the first year after birth can impact SIDS risk. Many of these factors can be controlled or changed to reduce the risk, but some cannot be controlled or changed.

One of the most effective actions that parents and caregivers can take to lower SIDS risk is to place their baby to sleep on their back for all sleep times.

Research shows that:3

  • Back sleeping carries the lowest risk for SIDS and is recommended.
  • Stomach sleeping carries higher risk than back sleeping for SIDS. It is not recommended.
  • The side-lying position also increases the risk. It is unstable and babies can easily roll to their stomach. It is not recommended.

Other known risk factors for SIDS include the following:

  • Preterm birth. Infants born before 37 weeks in the womb are at higher risk for SIDS than are infants born at full term.2
  • Smoking. Maternal smoking during pregnancy and smoke in the infant's environment increase the risk of SIDS.2
  • Race/ethnic origin. African American and American Indian/Alaska Native infants are at higher risk for SIDS than are White, Hispanic American, or Asian/Pacific Islander American infants.1
