What is a major risk factor for sudden infant death syndrome (SIDS)?

The major risk factor for sudden infant death syndrome (SIDS) is indeed related to the sleep position of the infant, particularly when they are placed to sleep on their stomachs. Research has consistently shown that infants who are laid down to sleep on their stomachs are at a significantly higher risk for SIDS compared to those who sleep on their backs. This is believed to be due to the potential for airway obstruction or impaired arousal mechanisms, which can occur when a baby is placed in this position.

The Back to Sleep campaign launched in the 1990s has successfully reduced the incidence of SIDS by recommending that infants be placed on their backs for all sleep times, including naps and overnight. This guideline is a fundamental part of safe sleep practices for infants and is supported by substantial epidemiological research.

While other factors may contribute to SIDS risk, such as environmental, biological, or physiological elements, the position in which an infant sleeps remains a primary focus in prevention strategies. Understanding this significant risk factor is key to educating caregivers about safe sleep practices.
