Higher SIDS Risk Found in Infants Placed in Unaccustomed Sleeping Position

03.03.2003


Infants accustomed to sleeping on their backs who are then placed to sleep on their stomachs or sides are at an increased risk for SIDS-greater than the increased SIDS risk of infants always placed on their stomachs or sides. The study, conducted by Kaiser Permanente in Northern and Southern California and supported by the National Institute of Child Health and Human Development (NICHD) and the National Institute on Deafness and Other Communications Disorders (NIDCD), appears in the current issue of the American Journal of Epidemiology.



The study also shows that infants sleeping on their sides are at an increased risk of SIDS. The researchers think that a large part of the risk may be due to the instability of the side sleeping position and the tendency for infants sleeping in this position to turn onto their stomachs.

The study, which was conducted in 11 counties in Northern and Southern California, is the first to examine the relationship between infant sleeping position and SIDS in a racially diverse U.S. population. The incidence of SIDS has declined over 50 percent since 1992, when the American Academy of Pediatrics recommended that infants be placed on their backs to sleep. Before the current study, evidence of the link between stomach sleeping and SIDS risk was based largely on overseas studies, where populations and cultural practices are different from those in the United States.


"These findings reinforce the importance of placing infants on their backs at all times," said Duane Alexander, M.D., Director of the NICHD. "This is the first study of infant sleeping position in relation to SIDS risk to be conducted completely after our ’Back to Sleep’ campaign was launched in 1994. It provides us with important information that will inform the campaign’s future messages."

The research team included De-Kun Li, M.D., Ph.D., senior investigator with Kaiser Permanente’s Division of Research in Oakland, CA. He and his colleagues completed in-person interviews with 197 women whose infants had died of SIDS and with 312 mothers of living infants. Each SIDS infant was compared to a living infant of the same race and age, and born in the same county. Both sets of women answered questions about infants’ sleeping positions, including:

  • the position in which the infant had last been put down to sleep
  • the position in which the infant was found
  • changes in sleeping position since birth, during the two weeks before death, and on the death date.

The researchers also collected information about bedding materials, type of mattress, room- or bed-sharing, room temperature, exposure to passive smoking, and infant sickness.

The researchers found that infants last placed on their sides for sleep were twice more likely to die of SIDS than infants last placed on their backs. In addition, the risk of SIDS was significantly increased if infants turned from their sides to their stomachs during sleep. While the reason isn’t clear, the researchers think that the instability of the side position makes it more likely for babies who are placed to sleep in this position to roll over onto their stomachs.

A pattern also emerged when the researchers looked specifically at the position in which an infant was last placed to sleep, compared to their usual sleeping position. If an infant who was usually placed to sleep in the low-risk position-- on the back--was then placed to sleep in a high-risk position (the stomach or side), his or her SIDS risk was seven to eight times greater than that of an infant who was always placed to sleep on his or her back.

"The message here is ’every night and nap time count’," said study co-author Dr. Marian Willinger of NICHD. "Parents and caregivers should place their babies on their backs every time they go to sleep. Consistency is the key."

One of the strengths of this study is that the researchers interviewed a racially- and culturally diverse group of mothers-White, African American, Hispanic, and Asian/Pacific Islander, although the small sample size limited the researchers’ ability to examine risk within each racial group. This study provides results from the first study of infant sleeping position in relation to SIDS risk to be collected entirely after the NICHD’s "Back to Sleep" campaign was launched to inform the public about the importance of sleep position in preventing SIDS.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
