What you really need to know about Sudden Infant Death Syndrome (SIDS)
Myth I, "Supine sleeping has greatly reduced the incidence of SIDS since 1992."
FALSE. SIDS deaths in the U.S. decreased from 4,895 in 1992 to 2,247 in 2004. But, during a similar time period, 1989 to 2004, SIDS being listed as the cause of death for sudden infant death (SID) decreased from 80% to 55%. According to Dr. John Kattwinkel, chairman of the Center for Disease Control (CDC) Special Task Force on SIDS "A lot of us are concerned that the rate (of SIDS) isn't decreasing significantly, but that a lot of it is just code shift. In fact, a resent recommendation published in the Forensic Science, Medicine, and Pathology Journal outlining new guidelines for SIDS classification resulted in a large percentage (69%) of original SIDS diagnosis being classified as positional asphyxiation. The report concludes that SIDS has been mislabeled....when the new recommended classification scheme is used; these deaths are not coded as SIDS, and indicated asphyxia as the potential contributor to, or as the specific cause of death, that appears to exist in a large percentage of cases originally designated as SIDS using older classification schemes. When certifiers use a classification system that focuses upon potential asphyxia in determining the cause of death the incidence of SIDS dramatically decreases.
Myth 2, "There is a regulated, standard, routine procedure for determining an infant death as SIDS. FALSE. Deaths that are determined to be SIDS deaths are as variable as the doctor or coroner determining the cause of death. There is currently no law regulating the national standards for investigation only voluntary recommendations. The Scripps review of 40,000 infant deaths going back to 1992 revealed that the quality of infant death investigations, the level of training for coroners, and the amount of oversight and review vary enormously across the country. In many cases, professional bias.” both for and against a diagnosis of SIDS” trumps medical evidence. President Obama and the CDC are only just (as of this year, 2009) beginning to make legislation to standardize these investigations.
Myth 3, "Supine sleeping, prevents SIDS."
FALSE. No one thing prevents SIDS. It is a mysterious occurrence that the medical world only has theories about. It seems to be an environmental incident, closely related to the infant's home environment, environmental exposures, pre and antenatal care, among other factors.
Myth 4, "Because I know that supine sleeping prevents SIDS, it must be safe to place my baby to sleep this way." Not entirely false, not entirely true. There are several current completed and working studies that indicate that supine sleeping may be dangerous. We do know that back sleeping decreases the baby’s comfort level with tummy time, and minimizes the baby’s sensory input to the oral motor region. Variety is normal, and sleeping in one position decreases “normal” variety for developing infants. Other side effects of the back sleeping position include increased rates of shoulder retraction, positional plagiocephaly (flattened back of the head) and positional torticollis . A research study on children with plagiocephaly found that 26% had mild to severe psychomotor delay. This study also showed that 10% of infants with plagiocephaly had mild to severe mental development delay. Because of the delays caused by back sleep, some medical professionals have suggested that the "normal" ages at which children had previously attained developmental milestones should be pushed back. This would enable medical professionals to consider children who previously were considered developmentally delayed as "normal" (Stevens P, "The Flip Side of Back to Sleep", The O&P Edge.)
Additional studies have reported that the following negative conditions are associated with the back sleep position: increase in sleep apnea, decrease in sleep duration, strabismus, social skills delays, and temporomandibular jaw difficulties . Other studies have reported that the prone position prevents subluxation of the hips, increases psychomotor development, prevents scoliosis, lessens the risk of gastroesophageal reflux, decreases infant screaming periods, causes less fatigue in infants, and increases the relief of infant colic. In addition, prior to the Back to Sleep campaign, many babies self-treated their own torticollis by turning their heads from one side to the other while sleeping in the prone position (Graham J, Gomez M, Halberg A, Earl D, Kreuzman J, Cui J, Guo X. Management of Deformational Plagiocephaly: Repositioning Versus Orthotic Therapy. The Journal of Pediatrics. 2005;10.016:258-22).
Dr. Rafael Pelayo from Stanford University and a number of other pediatric sleep researchers in the U.S. have stated that they believe that the American Academy of Pediatrics' recommendations regarding co-sleeping and pacifier use may have unintended consequences. They have stated that the SIDS prevention strategy of the American Academy of Pediatrics which keeps infants at a low arousal threshold and reduces the time in quiet sleep may be unhealthy for children. They state that slow wave sleep is the most restorative form of sleep and limiting this sleep in the first 12 months of life may have unintended consequences to both the sleep and the infant.
Since 1998 there have been several studies published which report that infants placed to sleep in the supine position lag in motor skills, social skills, and cognitive ability development when compared to infants who sleep in the prone position. In a 1998 article entitled “Effects of Sleep Position on Infant Motor Development” by Davis, Moon, Sachs, and Ottolini, the authors state We found that sleep position significantly impacts early motor development. The prone (stomach) sleeping infants in this study slept an average of 225.2 hours (8.3%) more in their first 6 months of life than the supine (back) sleeping infants.
Back-sleeping significantly reduces the amount of slow wave sleep that infants engage in and it is theorized that infants that have the brain-stem defect are at increased risk of being unable to arouse from SWS (also called deep sleep) and therefore have an increased risk of SIDS due to their decreased ability to arouse from SWS (Kattwinkel J, Hauck F.R., Moon R.Y., Malloy M and Willinger M Infant Death Syndrome: In Reply, Bed Sharing With Unimpaired Parents Is Not an Important Risk for Sudden\Pediatrics 2006;117;994-996). (Basically they're saying that if the infant has this defect, then they are at risk. Healthy infants are not apparently at risk for not arousing from SWS, and prenatal factors are what affect the development of the brainstem). SWS is vitally important to development and growth, and studies indicate that supine-positioned infants are being deprived of it, thereby aiding in cognitive and psychomotor delay.
The purpose of this post is the advocacy that “sleep should be safe in any position.” There is a lot of scientific data proving that air permeable sleep surfaces “significantly” reduce the risk of positional asphyxiation. The message that simply putting your baby to sleep on their back will save their lives is ludicrous. SIDS will happen......the true meaning of SIDS is an unexplained death. Positional asphyxiation and suffocation (which most of these deaths are labeled as SIDS) can, however, be prevented.
Always place baby in crib alone.
