SUID refers to the unexpected death of an infant under 1 year old when the cause of death is unknown prior to a more thorough examination. It includes sudden infant death syndrome (SIDS), as well as accidental suffocation Trusted Source Centers for Disease Control and Prevention (CDC) As the nation’s health protection agency, CDC saves lives and protects people from health threats.

According to data from the Centers for Disease Control and Prevention, there are about 3,400 SUID cases in the U.S. annually. The recent study, led by researchers from a division of the CDC, examined SUID incidents that occurred from 2011 to 2020.

The study found that infants were sharing a sleep surface in about 60% of the sudden unexpected infant deaths examined. Of those cases, around 75% of infants were in an adult bed, and about 68% were sharing the bed with adults only.

The researchers also looked at other factors involved in sudden unexpected infant deaths. Compared with SUID cases involving infants sleeping alone, those sharing a bed were more likely to be non-Hispanic Black, publicly insured, and under 3 months old.

The study found that infants were sharing a sleep surface in about 60% of the sudden unexpected infant deaths examined.

The data also revealed a higher rate of bed-sharing deaths among infants whose mother smoked while pregnant and those with a caregiver under the influence of drugs or alcohol at the time of the baby’s death.

The American Academy of Pediatrics states that infants should sleep alone and on their back in a crib or a bassinet on a firm, flat mattress with just a fitted sheet and no other objects present, including loose blankets, pillows, bumpers, and toys. Trusted Source American Academy of Pediatrics (AAP) The AAP and its member pediatricians dedicate their efforts and resources to the health, safety and well-being of infants, children, adolescents and young adults.
