Hi folks - I originally started this thread off in the pregnancy section before moving it here and over there things got quite heated and indiginant! Anyway I did some research looking at the research and the stats and I have copied the info below for your information.
Whoa - I seem to have kicked off a massive debate and as my maternity leave started today and I am a medic I thought I would have a look at some of the research into the FSIDs guidelines. It appears that 4 main papers are quoted, all of which seem to mainly look at co sleeping rather than room sharing.
- One of the papers I'm having difficulty accessing.
- Blair et al 1999 report, 'Cosleeping in terms of room sharing increases the sensory exchanges possible between parent and infants,22 but further research is required to investigate whether room sharing is protective in itself or merely a marker for hidden confounders not measured in this study'
- Tappin et al 2005 'Separate room not sharing (Table I) was not associated
with a risk of SIDS on univariate analysis (OR 1.32 95% CI
0.67, 2.60) but became a risk on multivariate analysis (OR
3.26 95% CI 1.03, 10.35). Variables were removed singly to
ascertain which were important in converting a nonsignificant
univariate model to a significantmultivariate model. The main
factor was parental smoking. Further stratified analysis
showed that separate room was associated with a significant risk of SIDS only if a parent smoked (OR 12.2 95% CI 2.25,
66.4) and not if parents were nonsmokers (OR 1.25 95% CI
0.16, 10.06).
- Carpenter 2004 This is the paper that I think the guidelines are probably most based on but it does combine the risk of bed sharing and room sharing. It uses Population attributable fractions (PAF; often called
population attributable risk) reported as percentages.These fractions estimate the expected percentage reduction
of cases if a particular exposure were eliminated.The largest
PAF was for sleeping place. This PAF was 35·9%
because, on average, 53% of cases were last left in another
room (range 18?88% across the 15 centres for which this
information was available) and 68% of the risk was
attributable. Additionally, the PAF for bed-sharing was
15·9%, so the data suggested that 52% of cases might
have been prevented had the baby slept in the parents?
room but not in their bed. They report in the discussion, 'An unexpected finding was that the factor with the largest PAF was that associated
with either the baby sleeping in another room or bedsharing.
On average, cases slept in another room 26
(11·3?41·5) days earlier than controls, but the OR did not
change with age. Why the baby sleeping in the parent?s
room reduced the risk is unclear.'
So there you go the hard statistical facts which may be a bit dry to digest but it essentially shows that there may be a small risk attributable to separate room but that this data is by no way conclusive or understood and is based much more on data regarding co sleeping. There are much clearer risks related to other issues - sleeping prone, temp, smoking.
Guidelines are just that and it is up to the individual to weigh up risks, there is no easy answer to the topic but I don't think that people should be too pious regarding this issue as the researchers themselves are not clear on causes/ confounders. Also the risk of SIDS is reduced greatly after 3 months so maybe it is worth taking that into account.
And finally everyone of course my bloody cat doesn't take precedent over the baby but living in a small london flat it is not possible to lock the cat out of the bedroom as we don't have a downstairs etc, she will just sit outside the bedroom door or the door to outside crying until we let her in - believe me if there was a way we could keep her out the room we would do it!
Anyway the cat net has arrived and we are just going to see how it goes, hopefully my cat won't be interested and if she is it may mean I need to decamp to the nursery for the first couple of months with baby.
