Milestones of the Back-to-Sleep Campaign
• 1992 – AAP issues statement that all healthy full term infants should be placed in non-prone positions to reduce the risk of SIDS.
• 1994 – The “Back to Sleep Campaign launched
• 1998 – The back sleeping campaign reduces SIDS deaths by 30 - 50 %.
• 2000 -- AAP statement - supine position poses lowest risk; side position less than prone
• 2005 – The AAP issues revised policy – supine only
• 2011 – The AAP updates its policy
6
Healthy People 2020 & 2011 AAP Safe Sleep Recommendations
• Healthy People 2020 goal – 75.9% back sleeping for infants < 8 months
• More detailed recommendations from AAP– Back only sleep position– Firm sleep surface– No soft objects, loose bedding or bumpers– Separate but close sleep environment– Encourage breastfeeding– Avoid smoking during pregnancy– Keep infants up to date on immunizations– Offer pacifier during sleep– Avoid commercial devices claiming to decrease

Barriers to Adopting Safe Sleep Practices
22
Barriers to Following Recommendations:Importance of Message and Messenger
• Lack of or wrong advice• Lack of trust in providers• Concerns about safety
– Worried about choking• Concerns about comfort
– Babies sleep better prone• Lack of knowledge
– Sleeping with mother or adult is best way to prevent SIDS
Colson ER, Levenson S, Rybin D, et al. Barriers to following the supine sleep recommendation among mothers at four centers for the Women, Infants, and Children Program. Pediatrics.2006;118(2):e243-e250.
23
Understanding Influence of the Messenger
Although physicians are expected to provide these recommendations, it is not clear –-
• How mothers of young infants rate physician qualification to give advice in the 3 AAP targeted areas of sleep position, bed sharing and pacifier use
• If maternal ratings of physician qualification are associated with the recommended maternal behavior in these 3 areas.
Smith LA, Colson E, Rybin D, , Colton T, Margolis A, Lister G, Corwin MJ. Parental Assessment of Physician Qualification to Give Advice on AAP Recommended Infant Sleep Practices Related to SIDS. Academic Pediatrics, 2010;10 (6):383-388
24
Methods
• Convenience sample of 1580 mothers of infants less than 8 months of age
• WIC centers in – Birmingham, AL– Clarksdale and Jackson, MS– Dallas, TX– Detroit, MI– New Haven, CT
• In-person, semi-structured interviews conducted June-December 2006 and 2007
25
Primary Outcome Variables
• Usually placed supine for sleep
• Usually does not share bed with adult during sleep
• Usually use pacifier during sleep
26
Independent Variables
Maternal rating of physician qualification
“Doctors give advice to parents about different topics. How qualified do you think your baby’s doctor is to give you advice on ….”
– 3 AAP targeted behaviors: sleep position, bed sharing, pacifier use
– 3 other domains: feeding practices, vaccinations, fever control
– Rating scale,1-5: High (4 or 5), Low ( ≤ 3)
27
Independent Variables
• Nature of physician advice– Concordant w/ recommendations– Contrary to recommendations– No advice

Limitations
• Data were collected from 6 geographic sites which may limit generalizability.
• We rely on parental report of the nature of physician advice and sleep behaviors.
33
Conclusion
• Low income, minority mothers rate physician qualification to give advice lower in the 3 AAP targeted safe sleep topics than in 3 more “medical” topics.
• Many mothers in this potentially vulnerable group report receiving no or non-AAP recommended advice, especially regarding pacifier use.
• High qualification ratings and the receipt of AAP-consistent advice from doctors are related to higher rates of recommended behavior.
34
Implications
• Focus on populations with low rates of acceptance of recommendations
• AAP may need to consider alternative methods, in addition to relying on physician education, to encourage adoption of recommended behaviors to prevent SIDS.
• Focus on message and messenger
Safe Sleep Controversies
36
What to do about bedsharing?
• Increase in infant deaths in setting of bedsharing in MA – More cases referred to
DCF
• Renewed focus on issue after controversial case in Milwaukee
37
Bedsharing Controversy
Why babies should never sleep alone: A reviewof the co-sleeping controversy in relation to SIDS,bedsharing and breast feeding
“At very least, we hope that the studies and data described in this paper, which show that co-sleeping at least in the form of roomsharing especially with an actively breast feeding mother saves lives, is a powerful reason why the simplistic, scientifically inaccurate and misleading statement ‘never sleep with your baby’ needs to be rescinded, wherever and whenever it is published.”
J McKenna, T McDade 2005
38
Why Mothers Chose Bedsharing?
Inner-City Caregivers’ Perspective on Bedsharing with their Infants
“Parents expressed divergent views about the safety of bed sharing: 1)ambivalence regarding balancing risks of overlaying and suffocation with benefits of bed sharing, or 2) assertion that bed sharing poses no risks for their child. Common to all groups was the finding that clinicians’ advice against bed sharing did not influence parents’ decision, but advice to increase safety when bed sharing would be appreciated.”
J Chianese, et al, 2009

41
Some Public Health Messaging
42
Baltimore City Effort: ABC
• “B’more for Healthy Babies: Every baby counts on you”
• Uses testimonials from parents whose infants have died in bedsharing situations
• Focus on 3 part “ABC” message– Alone– Back– Crib
Evolution of DPH Efforts
44
• Safe Sleep Policy Recommendation– The safest place for an infant to sleep is on
his or her back in the same room with a parent or caregiver and in a separate sleep space such as a crib or bassinet.
• Recommended sleep position• Recommended sleep environment• Bedsharing precautions
MA Department of Public HealthSafe Sleep Policy, 2009
45
Prior MA DPH Bedsharing Recommendations:
Risk Reduction Approach Some parents may decide to sleep in the same bed with their
infant despite the MDPH safe sleep policy recommendation that an infant sleep in a separate space. If a parent chooses to bed share, the MDPH offers the following precautions to reduce the risk of SIDS or an adult rolling over on an infant.
The MDPH recommends that an adult never sleep with an infant if the adult is:
• On soft bedding such as a sofa, couch, futon, cushioned chair, recliner, pillow, or water bed;
• Using medications that cause drowsiness;• Using any amount of alcohol or drugs (prescription or illicit) ;• Sick;• Unusually tired;• Severely overweight or obese; or• A smoker.
46
New AAP Guidelines Approach to Bedsharing
There are specific circumstances in which bed-sharing is particularly hazardous, and it should be stressed to parents that they avoid the following situations at all times:– When parent smokes– When parent uses alcohol, drugs or medications– When infant < 3 months– On waterbeds, sofas, armchairs– With soft bedding, pillows, blankets– With multiple people in the bed
47
Are risk reduction messages confusing?
• Risk reduction vs. strict prohibition – which is more effective and for whom?– Possibility that choice could exacerbate disparities
• What does it mean to acknowledge possibility of non-recommended behavior– “If you are not going to use a car seat, at least put
your toddler in seatbelt”– “If you are going to drink during pregnancy, at
least wait until the 3rd trimester when all of the organs are formed”
48
Safe Sleep Challenges
No cost, effective intervention – should be easy to adopt, but …
• Skepticism regarding mechanism• Alternative strongly held beliefs on
sleep position and environment– Concern about safety – preventing
choking– Co-sleeping is protective for baby– Better/longer sleep for mother and
baby– Facilitating breastfeeding
• Discounting doctor’s advice – sleep isn’t their domain
49
What’s Next?
• Issue new DPH Safe Sleep Policy• Communication campaign with
State Child Fatality Review Team partners and others
• Redesign public health messaging to target persistently vulnerable groups– Fear vs. positive messages
• Reinforce key points in all DPH programs, policies, outreach, contracts
